  • Prostate cancer: Short-course radiation as effective as longer-term treatments

    Prostate cancer: Short-course radiation as effective as longer-term treatments

    high angle view of a doctor holding a tablet with an illustration of male reproductive organs, showing a male patient during a consultation.

    It used to be that radiation therapy for prostate cancer involved weeks or months of repeat visits to a clinic for treatment. Today that’s not necessarily true. Instead of giving small doses (called fractions) per session until the full plan is completed, radiation delivery is moving toward high-dose fractions that can be given with fewer sessions over shorter durations.

    This “hypofractionated” strategy is more convenient for patients, and mounting evidence shows it can be accomplished safely. With one technology called stereotactic body radiation therapy (SBRT), patients can finish their treatment plans within a week, as opposed to a month or more. Several devices are available to deliver hypofractionated therapy, so patients may also hear it referred to as CyberKnife or by other brand names.

    An SBRT session takes about 20 to 30 minutes, and the experience is similar to receiving an x-ray. Often, doctors will first insert small metal pellets shaped like grains of rice into the prostate gland. Called fiducials, these pellets function as markers that help doctors target the tumor more precisely, so that radiation beams avoid healthy tissue. During treatment, a patient lies still while the radiation-delivery machine rotates around his body, administering the therapy.

    How good is SBRT at controlling prostate cancer? Results from a randomized controlled clinical trial show that SBRT and conventional radiotherapy offer the same long-term benefits.

    How the study was conducted

    The trial enrolled 874 men with localized prostate cancer, meaning cancer that is still confined to the prostate gland. The men ranged between 65 and 74 years in age, and all of them had prostate cancer with a low or intermediate risk of further progression. The study randomized each of the men to one of two groups:

    • Treatment group: The 433 men in this group each got SBRT at the same daily dose. The treatment plan was completed after five visits given over a span of one to two weeks.
    • Control group: The 441 men in this group got conventional radiotherapy over durations ranging from four to 7.5 weeks.

    None of the men received additional hormonal therapy, which is a treatment that blocks the prostate cancer–promoting effects of testosterone.

    What the study showed

    After a median duration of 74 months (roughly six years), the research found little difference in cancer outcomes. Among men in the treatment group, 26 developed visibly recurring prostate cancer, or a spike in prostate-specific antigen (PSA) levels suggesting that newly-forming tumors were somewhere in the body (this is called a biochemical recurrence). By contrast, 36 men from the control group developed visible cancer or biochemical recurrence. Put another way, 95.8% of men from the SBRT group — and 94.6% of men in the control group — were still free of prostate cancer.

    A word of caution

    Earlier results published two years into the same study showed higher rates of genitourinary side effects among the SBRT-treated men. Typical genitourinary side effects include inflammatory reactions that increase pain during urination, or that can make men want to urinate more often. Some men develop incontinence or scar tissues that make urination more difficult. In all, 12% of men in the SBRT group experienced genitourinary side effects at two years, compared to 7% of the control subjects.

    “Interestingly, patients who were treated with CyberKnife appeared to have lower significant toxicity at two years compared with those treated on other platforms,” said Dr. Nima Aghdam, a radiation oncologist at Beth Israel Deaconess Medical Center and an instructor of radiation oncology at Harvard Medical School. By five years, the differences in side effects between men treated with SBRT or conventional radiation had disappeared.

    The authors advised that men might consider conventional radiation instead of SBRT if they have existing urinary problems before being treated for cancer. Patients with baseline urinary problems are “more likely to have long-term toxic effects,” the authors wrote, adding that the new findings should “allow for better patient selection for SBRT, and more careful counseling.”

    “This is an important study that validates what’s becoming a standard practice,” said Dr. Marc Garnick, the Gorman Brothers Professor of Medicine at Harvard Medical School and Beth Israel Deaconess Medical Center, and editor in chief of the Harvard Medical School Guide to Prostate Diseases. “The use of a five-day treatment schedule has been well received by patients who live long distances from a radiation facility, given that treatment can be completed during the weekdays of a single week. As with any cancer treatment choice, the selection of the appropriate patient is crucial to minimize any potential side effects, and this can only be done after a careful consideration of the patient’s other medical conditions.”

    “This elegant study will put to rest any questions regarding the validity of SBRT as a standard-of-care option for many patients with prostate cancer,” Dr. Aghdam added. “Importantly in this trial, we see excellent outcomes for many patients who were treated with radiation alone. As this approach gains broad acceptance in radiation oncology practices, it remains critical to carefully consider each patient based on their baseline characteristics, and employ the highest level of quality assurance in delivering large doses of radiation in fewer fractions. As the overall duration of radiation therapy gets shorter, every single treatment becomes that much more important.”

  • Wildfires: How to cope when smoke affects air quality and health

    Wildfires: How to cope when smoke affects air quality and health

    A barge on a New York City river and skyscrapers, all blurred by orange-gray smoke from massive wildfires

    As wildfires become more frequent due to climate change and drier conditions, more of us and more of our communities are at risk for harm. Here is information to help you prepare and protect yourself and your family.

    How does wildfire smoke affect air quality?

    Wildfire smoke contributes greatly to poor air quality. Just like fossil fuel pollution from burning coal, oil, and gas, wildfires create hazardous gases and tiny particles of varying sizes (known as particulate matter, or PM10, PM2.5, PM0.1) that are harmful to breathe. Wildfire smoke also contains other toxins that come from burning buildings and chemical storage.

    The smoke can travel to distant regions, carried by weather patterns and jet streams.

    How does wildfire smoke affect our health?

    The small particles in wildfire smoke are the most worrisome to our health. When we breathe them in, these particles can travel deep into the lungs and sometimes into the bloodstream.

    The health effects of wildfire smoke include eye irritation, coughing, wheezing, and difficulty breathing. The smoke may also increase risk for respiratory infections like COVID-19. Other possible serious health effects include heart failure, heart attacks, and strokes.

    Who needs to be especially careful?

    Those most at risk from wildfire smoke include children, older adults, outdoor workers, and anyone who is pregnant or who has heart or lung conditions.

    If you have a chronic health condition, talk to your doctor about how the smoke might affect you. Find out what symptoms should prompt medical attention or adjustment of your medications. This is especially important if you have lung problems or heart problems.

    What can you do to prepare for wildfire emergencies?

    If you live in an area threatened by wildfires, or where heat and dry conditions make them more likely to occur:

    • Create an evacuation plan for your family before a wildfire occurs.
    • Make sure that you have several days on hand of medications, water, and food that doesn't need to be cooked. This will help if you need to leave suddenly due to a wildfire or another natural disaster.
    • Regularly check this fire and smoke map, which shows current wildfire conditions and has links to state advisories.
    • Follow alerts from local officials if you are in the region of an active fire.

    What steps can you take to lower health risks during poor air quality days?

    These six tips can help you stay healthy during wildfire smoke advisories and at other times when air quality is poor:

    • Stay aware of air quality. AirNow.gov shares real-time air quality risk category for your area accompanied by activity guidance. When recommended, stay indoors, close doors, windows, and any outdoor air intake vents.
    • Consider buying an air purifier. This is also important even when there are no regional wildfires if you live in a building that is in poor condition. See my prior post for tips about pollution and air purifiers. The EPA recommends avoiding air cleaners that generate ozone, which is also a pollutant.
    • Understand your HVAC system if you have one. The quality and cleanliness of your filters counts, so choose high-efficiency filters if possible, and replace these as needed. It's also important to know if your system has outdoor air intake vents.
    • Avoid creating indoor pollution. That means no smoking, no vacuuming, and no burning of products like candles or incense. Avoid frying foods or using gas stoves, especially if your stove is not well ventilated.
    • Make a "clean room." Choose a room with fewer doors and windows. Run an air purifier that is the appropriate size for this room, especially if you are not using central AC to keep cool.
    • Minimize outdoor time and wear a mask outside. Again, ensuring that you have several days of medications and food that doesn't need to be cooked will help. If you must go outdoors, minimize time and level of activity. A well-fitted N95 or KN95 mask or P100 respirator can help keep you from breathing in small particles floating in smoky air (note: automatic PDF download).

  • 21 spices for healthy holiday foods

    21 spices for healthy holiday foods

    Colorful herbs and spices arrayed in sprays and heaped on silver teaspoons against a dark background

    The holiday season is one of the hardest times of the year to resist salty, fatty, sugary foods. Who doesn’t want to enjoy the special dishes and treats that evoke memories and meaning — especially during the pandemic? Physical distancing and canceled gatherings may make you feel that indulging is a way to pull some joy out of the season.

    But stay strong. While it’s okay to have an occasional bite or two of marbled roast beef, buttery mashed potatoes, or chocolate pie, gorging on them frequently can lead to weight gain, and increased blood pressure, blood sugar, and “bad” LDL cholesterol.

    Instead, skip the butter, cream, sugar, and salt, and flavor your foods with herbs and spices.

    The bounty of nature’s flavor-makers go beyond enticing tastes, scents, and colors. Many herbs and spices contain antioxidants, flavonoids, and other beneficial compounds that may help control blood sugar, mood, and inflammation.

    Amp up holiday foods with herbs and spices

    Try flavoring your foods with some of the herbs and spices in the list below. Play food chemist and experiment with combinations you haven’t tried before. The more herbs and spices you use, the greater the flavor and health rewards. And that’s a gift you can enjoy all year through.

    Allspice: Use in breads, desserts, and cereals; pairs well with savory dishes, such as soups, sauces, grains, and vegetables.

    Basil: Slice into salads, appetizers, and side dishes; enjoy in pesto over pasta and in sandwiches.

    Cardamom: Good in breads and baked goods, and in Indian dishes, such as curry.

    Cilantro: Use to season Mexican, Southwestern, Thai, and Indian foods.

    Cinnamon: Stir into fruit compotes, baked desserts, and breads, as well as Middle Eastern savory dishes.

    Clove: Good in baked goods and breads, but also pairs with vegetable and bean dishes.

    Cumin: Accents Mexican, Indian, and Middle Eastern dishes, as well as stews and chili.

    Dill weed: Include in potato dishes, salads, eggs, appetizers, and dips.

    Garlic: Add to soups, pastas, marinades, dressings, grains, and vegetables.

    Ginger: Great in Asian and Indian sauces, stews, and stir-fries, as well as beverages and baked goods.

    Marjoram: Add to stews, soups, potatoes, beans, grains, salads, and sauces.

    Mint: Flavors savory dishes, beverages, salads, marinades, and fruits.

    Nutmeg: Stir into fruits, baked goods, and vegetable dishes.

    Oregano: Delicious in Italian and Mediterranean dishes; it suits tomato, pasta, grain dishes, and salads.

    Parsley: Enjoy in soups, pasta dishes, salads, and sauces.

    Pepper (black, white, red): Seasons soups, stews, vegetable dishes, grains, pastas, beans, sauces, and salads.

    Rosemary: Try it in vegetables, salads, vinaigrettes, and pasta dishes.

    Sage: Enhances grains, breads, dressings, soups, and pastas.

    Tarragon: Add to sauces, marinades, salads, and bean dishes.

    Thyme: Excellent in soups, tomato dishes, salads, and vegetables.

    Turmeric: Essential in Indian foods; pairs well with soups, beans, and vegetables.

  • Beyond the usual suspects for healthy resolutions

    Beyond the usual suspects for healthy resolutions

    photo of a new pair of white and orange sneakers in a box, viewed from above on a white and orange background with an angled division between the colors

    Early in the new year, promises to reboot your health typically focus on diet, exercise, and weight loss. And by now you may have begun making changes — or at least plans — to reach those goals. But consider going beyond the big three.

    Below are 10 often-overlooked, simple ideas to step up personal health and safety. And most won’t make you break a sweat.

    Review your health portals

    Your medical information is kept in electronic records. You have access to them through the patient portal associated with your doctor’s office. Set aside time to update portal passwords and peruse recent records of appointments, test results, and notes your doctor took during your visits.

    “Many studies have shown that when patients review the notes, they remember far better what went on during interactions with their clinicians, take their medicines more effectively, and pick up on errors — whether it’s an appointment they forgot to make or something their doctor, nurse, or therapist got wrong in documenting an encounter,” says Dr. Tom Delbanco, the John F. Keane & Family Professor of Medicine at Harvard Medical School and cofounder of the OpenNotes initiative, which led shared clinician notes to become the new standard of care.

    Doing this can help you become more engaged in your care. “We know from numerous studies that engaged patients who share decisions with those caring for them have better outcomes,” he adds.

    Ask about health insurance freebies

    Your insurance plan may offer perks that can lead to better health, such as:

    • weight loss cessation programs
    • quit-smoking programs
    • free or reduced gym memberships.

    Some insurers even offer breastfeeding counseling and equipment. Call your insurance company or take a close look at their website to find out if there’s anything that would help you.

    Get rid of expired medications

    Scour your cabinets for expired or unneeded drugs, which pose dangers for you and others. Look for prescription and over-the-counter medications (pills, potions, creams, lotions, droppers, or aerosol cans) as well as supplements (vitamins, minerals, herbs).

    Bring your finds to a drug take-back site, such as a drugstore or law enforcement office, or a medical waste collection site such as the local landfill.

    As a last resort, toss medications into the trash, but only after mixing them with unappealing substances (such as cat litter or used coffee grounds) and placing the mixture in a sealable plastic bag or container.

    Invest in new sneakers

    The wrong equipment can sabotage any exercise routine, and for many people the culprit is a worn pair of sneakers. Inspect yours for holes, flattened arch support, and worn treads. New sneakers could motivate you to jazz up your walking or running routine.

    For example, if it’s in the budget, buy a new pair of walking shoes with a wide toe box, cushy insoles, good arch support, a sturdy heel counter (the part that goes around your heel), stretchy uppers, and the right length — at least half an inch longer than your longest toe.

    Cue up a new health app

    There are more than 350,000 health apps geared toward consumer health. They can help you with everything from managing your medications or chronic disease to providing instruction and prompts for improving diet, sleep, or exercise routines, enhancing mental health, easing stress, practicing mindfulness, and more.

    Hunt for apps that are free or offer a free trial period for a test drive. Look for good reviews, strong privacy guardrails, apps that don’t collect too much information from you, and those that are popular — with hundreds of thousands or millions of downloads.

    Make a schedule for health screenings and visits

    Is it time for a colonoscopy, mammogram, hearing test, prostate check, or comprehensive eye exam? Has it been a while since you had a dermatologist examine the skin on your whole body? Should you have a cholesterol test or other blood work — and when is a bone density test helpful?

    If you’re not sure, call your primary care provider or any specialists on your health team to get answers.

    Four more simple healthy steps

    The list of steps you can take this year to benefit your health can be as long as you’d like it to be. Jot down goals any time you think of them.

    Here are four solid steps to start you off:

    • Take some deep breaths each day. A few minutes of daily slow, deep breathing can help lower your blood pressure and ease stress.
    • Get a new pair of sunglasses if your old ones have worn lenses. Make sure the new pair has UV protection (a special coating) to block the sun’s ultraviolet (UV) light, which can cause eye damage and lead to permanent vision loss.
    • Make a few lunch dates or phone dates with friends you haven’t seen in a while. Being socially connected wards off loneliness and isolation, which can help lower certain health risks.
    • Do a deep cleaning on one room in your home per week. Dust and mold can trigger allergies, asthma, and even illness.

    You don’t have to do all of these activities at once. Just put them on your to-do list, along with the larger resolutions you’re working on. Now you’ll have a curated list of goals of varying sizes. The more goals you reach, the better you’ll feel. And that will make for a very healthy year, indeed.

  • Winter hiking: Magical or miserable?

    Winter hiking: Magical or miserable?

    Winter hiker, viewed from waist down, wearing blue snowpants and walking on a snowy trail between pine trees

    By midwinter, our urge to hibernate can start to feel constricting instead of cozy. What better antidote to being cooped up indoors than a bracing hike in the crisp air outdoors?

    Winter backdrops are stark, serene, and often stunning. With fewer people on the trail, you may spot more creatures out and about. And it’s a prime opportunity to engage with the seasons and our living planet around us, says Dr. Stuart Harris, chief of the Division of Wilderness Medicine at Massachusetts General Hospital. But a multi-mile trek through rough, frosty terrain is far different than warm-weather hiking, requiring consideration of health and safety, he notes. Here’s what to know before you go.

    Winter hiking: Safety first

    “The challenge of hiking when environmental conditions are a little more demanding requires a very different approach on a winter’s day as opposed to a summer’s day,” Dr. Harris says. “But it gives us a chance to be immersed in the living world around us. It’s our ancient heritage.”

    A safety-first attitude is especially important if you’re hiking with others of different ages and abilities — say, with older relatives or small children. It’s crucial to have both the right gear and the right mindset to make it enjoyable and safe for all involved.

    Planning and preparation for winter hikes

    Prepare well beforehand, especially if you’re mixing participants with vastly different fitness levels. Plan your route carefully, rather than just winging it.

    People at the extremes of age — the very old or very young — are most vulnerable to frigid temperatures, and cold-weather hiking can be more taxing on the body. “Winter conditions can be more demanding on the heart than a perfectly-temperatured day,” Harris says. “Be mindful of the physical capabilities of everyone in your group, letting this define where you go. It’s supposed to be fun, not a punishing activity.”

    Before setting out:

    • Know how far, high, and remote you’re going to go, Dr. Harris advises, and check the forecast for the area where you’ll be hiking, taking wind chill and speed into account. Particularly at higher altitudes, weather can change from hour to hour, so keep abreast of expectations for temperature levels and any precipitation.
    • Know if you’ll have access to emergency cell coverage if anything goes wrong.
    • Always share plans with someone not on your hike, including expected route and time you’ll return. Fill out trailhead registers so park rangers will also know you’re on the trail in case of emergency.

    What to wear for winter hikes

    Prepare for extremes of cold, wind, snow, and even rain to avoid frostbite or hypothermia, when body temperature drops dangerously low.

    • Dress in layers. Several thin layers of clothing are better than one thick one. Peel off a layer when you’re feeling warm in high sun and add it back when in shadow. Ideally, wear a base layer made from wicking fabric that can draw sweat away from the skin, followed by layers that insulate and protect from wind and moisture. “As they say, there’s no bad weather, just inappropriate clothing,” Dr. Harris says. “Take a day pack or rucksack and throw a couple of extra thermal layers in. I never head out for any hike without some ability to change as the weather changes.”
    • Protect head, hands, and feet. Wear a wool hat, a thick pair of gloves or mittens, and two pairs of socks. Bring dry spares. Your boots should be waterproof and have a rugged, grippy sole.
    • Wear sunscreen. You can still get a sunburn in winter, especially in places where the sun’s glare reflects off the snow.

    Carry essentials to help ensure safety

    • Extra food and water. Hiking in the cold takes serious energy, burning many more calories than the same activity done in summer temperatures. Pack nutrient-dense snacks such as trail mix and granola bars, which often combine nuts, dried fruit, and oats to provide needed protein, fat, and calories. It’s also key to stay hydrated to keep your core temperature normal. Bonus points for bringing a warm drink in a thermos to warm your core if you’re chilled.
    • First aid kit. Bandages for slips or scrapes on the trail and heat-reflecting blankets to cover someone showing signs of hypothermia are wise. Even in above-freezing temperatures, hypothermia is possible. Watch for signs such as shivering, confusion, exhaustion, or slurring words, and seek immediate help.
    • Light source. Time your hike so you’re not on the trail in darkness. But bring a light source in case you get stuck. “A flashlight or headlamp is pretty darn useful if you’re hiking anywhere near the edges of daylight,” Harris says.
    • Phone, map, compass, or GPS device plus extra batteries. Don’t rely on your phone for GPS tracking, but fully charge it in case you need to reach someone quickly. “Make sure that you have the technology and skill set to be able to navigate on- or off-trail,” Harris says, “and that you have a means of outside communication, especially if you’re in a large, mixed group.”

  • Is the portfolio diet the best diet ever?

    Is the portfolio diet the best diet ever?

    White table with healthy plant-based foods including Buddha bowl, lettuce wraps, colorful vegetables, grains, legumes, and dips

    News flash: What we eat can play a pivotal role in warding off — or treating — disease and enhancing quality of life. You may already believe this, and certainly mounting evidence supports that idea. But on the cluttered shelf of diets claiming top health benefits, which one ranks as the absolute best?

    That’s a trick question. In fact, there is no single best diet. A good diet for me may be different from what’s best for you. And for either of us, there may be several good choices with no clear winner.

    How can you choose the right diet for you?

    When thinking about what diet might be best for you, ask yourself:

    • What goals are most important? A goal might be weight loss, improved health, avoiding disease, or something else.
    • How do you define “best”? For some people, best means the diet with the highest number of health benefits. For others, it may focus on one specific health benefit, such as lowering cholesterol. Still other people may prefer a diet that delivers the greatest benefit for the lowest cost. Or a diet that is healthy and also easy to stick with.
    • What health problems do you have? One diet may have an advantage over another depending on whether you have cancer, cardiovascular disease, diabetes, or none of these.
    • Which foods do you like best? Your tastes, culture, and location may shape your dietary preferences, and powerfully affect how likely you are to stick with a specific diet.

    Which diets are high in health benefits?

    Two very well studied diets demonstrate clear benefit, including lowering risk for heart disease and stroke and reducing high blood pressure: the Mediterranean diet and the DASH diet.

    But the portfolio diet may be as good as or better than these plans, at least for combatting cardiovascular disease that contributes to clogged blood vessels, heart attacks, and stroke. What? You’ve never heard of the portfolio diet? You’re not alone.

    What is the portfolio diet?

    Just as a financial advisor may recommend having a diverse investment portfolio — not just stocks, not just bonds — the portfolio diet follows suit. This largely plant-based diet focuses on diverse foods and food groups proven to lower harmful blood lipids, including LDL (so-called bad cholesterol) and triglycerides.

    If you choose to follow this eating pattern, you simply need to learn which foods have a healthy effect on blood lipids and choose them in place of other foods. For some people, this only requires small tweaks to embrace certain foods while downplaying other choices. Or it may call for a bigger upheaval of longtime eating patterns.

    Which foods are encouraged in the portfolio diet?

    Below are the basics. Eating more of these foods regularly may help lower levels of harmful blood lipids:

    • plant-based proteins such as soy, beans, tofu, peas, nuts, and seeds
    • high-fiber foods such as oats, barley, berries, apples, and citrus fruit; other examples include bran, berries, okra, and eggplant
    • phytosterols, which are a natural compound in plant-based foods such as whole grains, fruits, vegetables, and nuts (other sources are foods fortified with phytosterols or dietary supplements)
    • plant-based oils high in monounsaturated fat such as olive oil, avocado oil, safflower oil, and peanut oil.

    See? Some of your favorite foods make the cut. That’s a major strength of this approach: the list of recommended foods is long. So, it’s likely that you’re already eating and enjoying some of the recommended foods.

    Which foods are not part of the portfolio diet?

    It’s worth highlighting foods that are not on this list, such as

    • red meat
    • highly processed foods
    • refined grains and added sugar, which may contribute to chronic inflammation
    • butter, cream, and other dairy products high in saturated fat and cholesterol.

    What can the portfolio diet do for you?

    Researchers have shown that the portfolio diet can improve blood lipids. But can it also lower the risk of heart attack, stroke, and other cardiovascular problems?

    Yes, according to a 2023 study published in Circulation. More than nearly 17,000 people kept careful food diaries for 30 years. Those who most closely followed the portfolio diet, compared with those who followed it the least, were more likely to have favorable lipids and inflammation. They were also 14% less likely to have a heart attack, and 14% less likely to have a stroke.

    This was true even after accounting for factors that could affect cardiovascular disease risk, such as taking cholesterol-lowering medications, exercise, smoking, or having diabetes or a family history of cardiovascular disease.

    Because this was an observational study, it can’t conclusively prove that the portfolio diet, rather than another factor, was responsible for the observed cardiovascular benefits. And we don’t know how much benefit came from reducing or eliminating certain types of foods, rather than from the specific foods eaten.

    Does the portfolio diet help people lose weight or deliver other health advantages?

    What about the portfolio diet for weight loss? Although some people lose weight on the portfolio diet, it’s not billed as a weight-loss diet. Understanding its potential benefit for other conditions such as obesity, cognitive decline, diabetes, and cancer awaits further research.

    Go beyond diet to boost health

    Of course, diet is not the only way to improve cardiovascular health and your overall health. You’ll stay healthier by

    • not smoking
    • getting regular exercise
    • maintaining a healthy blood pressure and weight
    • preventing diabetes when possible, or getting good medical care to treat it if necessary
    • taking prescribed medications such as cholesterol-lowering drugs.

    The bottom line

    It’s probably best to move past the idea of there being a single best diet. The overall pattern of your diet and your portion sizes are probably more important. For most people, it’s also a good idea to move away from restrictive diets that are nearly impossible to stick with and toward healthier overall eating patterns. The portfolio diet checks both those boxes.

    There’s a lot of overlap between the portfolio diet and other healthy diets. So, no one should be suggesting it’s the best diet ever. But if you’re trying to eat healthier, it’s a great place to start.

    Although inflammation serves a vital role in the body’s defense and repair systems, chronic inflammation can cause more harm than good. And that may make you wonder: what can I do about it?

    In fact, there’s a lot you can do. And you may already be doing it. That’s because some of the most important ways to fight inflammation are measures you should be taking routinely.

    Let’s take a look at key elements of fighting chronic inflammation: prevention, detection, and treatment.

    Six ways to prevent unhealthy inflammation

    Six of the most effective ways to ward off inflammation are:

    • Choose a healthy diet. Individual foods have a rather small impact on bodywide inflammation, so no, eating more kale isn’t likely to help much. But making sure you eat lots of fruits and vegetables, whole grains, healthy fats, and legumes — sometimes called an anti-inflammatory diet — may reduce inflammation and lower risk for chronic illnesses like diabetes and heart disease. Not only can these diets help reduce inflammation on their own, but replacing foods that increase inflammation (such as sugary drinks and highly processed foods) benefits your body, too.
    • Exercise regularly.Physical activity may help counter some types of inflammation through regulation of the immune system. For example, exercise has anti-inflammatory effects on white blood cells and chemical messengers called cytokines.
    • Maintain a healthy weight. Because excess fat in cells stimulates bodywide inflammation, avoiding excess weight is an important way to prevent fat-related inflammation. Keeping your weight in check also reduces the risk of type 2 diabetes, a condition that itself causes chronic inflammation.
    • Manage stress. Repeatedly triggered stress hormones contribute to chronic inflammation. Yoga, deep breathing, mindfulness practices, and other forms of relaxation can help calm your nervous system.
    • Do not smoke. Toxins inhaled in cigarette smoke trigger inflammation in the airways, damage lung tissue, and increase the risk of lung cancer and other health problems.
    • Try to prevent inflammatory conditions, such as
      • Infection: Take measures to avoid infections that may cause chronic inflammation. HIV, hepatitis C, and COVID-19 are examples. Practicing safer sex, not sharing needles, and getting routine vaccinations are examples of effective preventive measures.
      • Cancer: Get cancer screening on the schedule recommended by your doctors. For example, colonoscopy can detect and remove polyps that could later become cancerous.
      • Allergies: By avoiding triggers of asthma, eczema, or allergic reactions you can reduce the burden of inflammation in your body.

    Do you need tests to detect inflammation?

    While testing for inflammation is not routinely recommended, it can be helpful in some situations. For example, tests for inflammation can help to diagnose certain conditions (such as temporal arteritis) or monitor how well treatment is controlling an inflammatory condition (such as Crohn’s disease or rheumatoid arthritis).

    However, there are no perfect tests for inflammation. And the best way to know if inflammation is present is to have routine medical care. Seeing a primary care physician, reviewing your medical history and any symptoms you have, having a physical examination, and having some basic medical tests are reasonable starting points. Such routine care does not typically include tests for inflammation.

    How is inflammation treated?

    At first glance, treating unhealthy, chronic inflammation may seem simple: you take anti-inflammatory medications, right? Actually, there’s much more to it than that.

    Anti-inflammatory medicines can be helpful to treat an inflammatory condition. And we have numerous FDA-approved options that are widely available — many in inexpensive generic versions. What’s more, these medicines have been around for decades.

    • Corticosteroids, such as prednisone, are the gold standard. These powerful anti-inflammatory medicines can be lifesaving in a variety of conditions, ranging from asthma to allergic reactions.
    • Other anti-inflammatory medicines can also be quite effective for inflammatory conditions. Ibuprofen, naproxen, and aspirin — which may already be in your medicine cabinet — are among the 20 or so nonsteroidal anti-inflammatory drugs (NSAIDs) that come as pills, tablets, liquids taken by mouth, products applied to skin, injections, and even suppositories.

    Yet relying on anti-inflammatory medicines alone for chronic inflammation is often not the best choice. That’s because these medicines may need to be taken for long periods of time and often cause unacceptable side effects. It’s far better to seek and treat the cause of inflammation. Taking this approach may cure or contain many types of chronic inflammation. It may also eliminate the need for other anti-inflammatory treatments.

    For example, chronic liver inflammation due to hepatitis C infection can lead to liver scarring, cirrhosis, and eventually liver failure. Medicines to reduce inflammation do not solve the problem, aren’t particularly effective, and may cause intolerable side effects. However, treatments available now can cure most cases of chronic hepatitis C. Once completed, there is no need for anti-inflammatory treatment.

    Similarly, among people with rheumatoid arthritis, anti-inflammatory medicines such as ibuprofen or steroids may be a short-term approach that helps ease symptoms, yet joint damage may progress unabated. Controlling the underlying condition with medicines like methotrexate or etanercept can protect the joints and eliminate the need for other anti-inflammatory drugs.

    The bottom line

    Even though we know that chronic inflammation is closely linked to a number of chronic diseases, quashing inflammation isn’t the only approach, or the best one, in all cases.

    Fortunately, you can take measures to fight or even prevent unhealthy inflammation. Living an “anti-inflammatory life” isn’t always easy. But if you can do it, there’s an added bonus: measures considered to be anti-inflammatory are generally good for your health, with benefits that reach well beyond reducing inflammation.

  • No-cost, low-cost, and bigger splurges for climate-conscious gifts

    No-cost, low-cost, and bigger splurges for climate-conscious gifts

    Looking for gifts to give or donate this year? Climate-conscious gifts come in many guises. They may directly support our environment, for example, or aim to reduce fossil fuel use and electronic, textile, and food waste. Or they might offer enjoyable, creative ways to connect, reuse, and recycle — and possibly even regift.

    “Our purchases and choices impact our climate and planet,” notes Dr. Wynne Armand, a physician and associate director of the Massachusetts General Hospital Center for the Environment and Health. Small steps like these do help, she says, even when the complex issues of climate change leading to health-compromising pollution, extreme weather, and a stressed planet feel so large and overwhelming.

    “Unquestionably, we need bold, strong leaders to seek policy changes that address these problems at a systems level. But, as individuals we can make a difference through small steps,” says Dr. Armand. “Our choices help drive cultural and market shifts that hopefully push our neighbors, businesses, and policy leaders in the right direction.”

    Four climate-conscious principles for gifting

    • Channel the 5 Rs. Refuse, reduce, reuse, repurpose, and only then recycle. Say no to excess. Comic sections from print newspapers or beautiful images from last year’s calendars or magazines make great envelopes and gift wrap. If you’re choosing clothes, consider buying upcycled clothing or at resale shops, as appropriate.
    • Beware of greenwashing. Eco-consciousness is big business, and the benefits of what you buy may be questionable. If you have a small lawn that needs infrequent maintenance, says Dr. Armand, keeping a trusty (albeit gas-fueled) mower could be a better choice for the planet than buying an electric mower, when factoring in upstream costs of natural resources and the carbon footprint required to manufacture and ship the new — and toss out the not-so-old. (Alternatively, maybe it’s time to replant that lawn with wildflowers and vegetables?)
    • Skip what’s not needed. A new backpack crafted from water bottles? Another sweater to add to a closetful? If there’s no apparent need, think twice about purchases.
    • Double down on experiences and connection. Think concert tickets, museum passes, or energetic options like rock-climbing gym passes and outdoor skills classes. “Gifts of experience are great, especially for people who already have all they need. If you buy for two or try a skills swap you also get to enjoy that time together,” says Dr. Armand.

    25 climate-conscious gifts

    Below are 25 suggestions for climate-conscious giving intended to work with many budgets.

    Small but mighty climate-conscious gifts

    1. Soft, warm sweaters, thick socks, or puffer vests can help people turn down the heat, saving energy resources and money.

    2. Rechargeable batteries reduce materials and packaging waste.

    3. An electric kettle, induction hot plate, or toaster oven can help limit indoor pollutants from gas stoves.

    4. Perfectly Good Food: A Totally Achievable Zero Waste Approach to Home Cooking aims to pare back food waste and is available online.

    5. Shop local artisans and craft fairs rather than buying online.

    6. Plants brighten any room and help scrub the air: choose easy-care varieties, such as succulents, colorful coleus, and some herbs.

    7. Protect the natural world: birds, bees, and other insects could use your help. Consider a small bird feeder that attaches to a window, a bee house, gardening tools, or seeds for a pollinator garden of colorful flowers.

    8. Donate to national or worldwide climate or environmental organizations, local green spaces, and local conservation groups.

    9. Gift green bonds for companies that support renewable energy — do your research, though, because greenwashing can be an issue.

    10. Secret gifter-giftee swaps with large groups save sanity and throttle back waste.

    Bigger splurges on climate-conscious gifts

    11. When appliances reach the end of useful life, consider replacing gas stoves, water heaters, washers, dryers, and similar items with electric versions.

    12. Plan a week of nearby tours and events with friends or family instead of flights and faraway travel.

    13. Gift clothes and tools to enjoy the natural world: for example, warm, waterproof clothing and hiking boots, cross-country skis or skates, good binoculars for bird-watching.

    14. Composters (or a weekly composting service subscription) recycle food scraps and organic waste into soil-enriching “black gold.”

    15. Electric bikes may be a boon if they reduce reliance on vehicles using fossil fuels.

    16. Help fund energy-efficient heat pumps or renewable solar energy.

    17. Substantial donations and sustaining donor gifts to climate-conscious organizations can help in many ways.

    No-cost climate-conscious gifts

    18. Offer to gather information on big-ticket items in the big splurges section, including state and federal rebates and 0% loans for heat pumps, energy-efficient furnaces, solar panels, and energy-efficient appliances.

    19. Teach a skill one-on-one, such as home repair, skating, chess, training for a mud run, knitting, cooking, orienteering, or gardening, or organize skills swaps with friends.

    20. Gift the human power needed to replant portions of a lawn with vegetables or pollinator plants, or make a rain garden (note: automatic download) to help divert storm water.

    21. Combine a no-cost reminder of the environmental benefits of no-mow May and leave the leaves campaigns with an offer to help peel back these layers come spring.

    22. Friends often want to gift one another — costly generosity that can prompt last-minute candle-buying. As an alternative, gather a small group of friends for a clothing, accessories, and candle swap of new, never-took-the-price-tag-off, nearly new, and well-loved items.

    23. Offer a DIY nature or bird walk for two. Try the free Pl@ntnet and Merlin apps if you can’t tell a pin oak from a petunia or a robin from a California condor.

    24. If you buy for a ton of people, buy in bulk and figure out how to parcel it out in more sustainable packaging.

    25. Make dinner, fudge, or another treat with friends — not completely free, but always a great way to gather your community.
