Here Are the 50 Best Healthy-Eating Tips of All Time

Updated: Aug. 08, 2018

Nutrition experts share their best tips to help you live longer, feel better, and shed those extra pounds.


Eat sauerkraut if you have a cold

“When naturally fermented and refrigerated (not pasteurized), sauerkraut, kimchi, yogurt, and kefir contain natural probiotics and help populate your gut with healthy bacteria that can protect you from colds and the flu.”  —Justin Sonnenburg, PhD, associate professor of microbiology and immunology at Stanford University and author of The Good Gut. These are the best probiotic foods for your gut.


A dash of turmeric can prevent cancer

“Many clinical trials have shown it could play a role in preventing or treating heart disease, osteoarthritis, and some cancers. I recommend a quarter teaspoon a day. If you don’t enjoy the taste, buy capsules.” —Michael Greger, MD, a physician who specializes in nutrition and the author of How Not to Die. Here’s how turmeric can soothe stomach problems.


Canned tuna packs a protein punch

“It’s one of the most affordable proteins in the supermarket, and it’s packed with omega-3s, vitamin D, and selenium. Snack on it with whole-grain crackers.”—Kate Geagan, MS, RD, nutritionist and author of Go Green, Get Lean


Stay mentally sharp with a fishy diet

“In one large study, having at least one fish meal a week was associated with a 60 percent reduction in the risk of developing Alzheimer’s disease.” Other studies have found that eating fish slashes your chance of dying from heart disease by about a third. —Martha Clare Morris, ScD, director of the Section of Nutrition and Nutritional Epidemiology at Rush University Medical Center. Here are the omega-3 foods that could add years to your life.


 Dark chocolate (with 70 percent cacao) halts cravings

“This treat has been shown to boost good HDL cholesterol, lower bad LDL cholesterol, reduce blood pressure, boost brain health, and enhance mood. Research also shows it curbs cravings for both sweet and salty foods.” —Cynthia Sass, MPH, RD, author of Slim Down Now: Shed Pounds and Inches with Real Food, Real Fast.


Make berries your go-to fruit

“Berries have high levels of antioxidants that may lower your risk of heart disease, some types of cancer, diabetes, and cognitive decline. Look for black raspberries (in the freezer department of high-end grocery stores), blueberries, cranberries, and black currants.” —David C. Nieman, DrPH, FACSM, director of the Human Performance Lab at Appalachian State University


When buying cabbage, choose purple

“It has the same eyesight- and brain-protecting antioxidants as berries do, at a fraction of the cost. Slice off shreds to use as a healthy, colorful garnish.” —Michael Greger, MD. These are the daily habits of naturally thin people.

Eat more leafy green veggies as you get older

“One study found that seniors who ate at least one serving of leafy greens a day had the cognitive ability of someone 11 years younger.” —Martha Clare Morris, ScD

Beans can help you live longer

“A cup every day may add years to your life. They’re cheap, they provide way more protein dollar-for-dollar than meat does, they have complex carbohydrates, and they’re full of fiber. Plus beans help the good bacteria in your gut flourish, helping you lose weight and lowering inflammation that causes disease.” —Dan Buettner, a National Geographic Fellow and the author of The Blue Zones Solution: Eating and Living Like the World’s Healthiest People


Add nuts to your breakfast

“Five or more five-ounce servings of nuts throughout the week may cut your risk of heart disease by up to half. It doesn’t matter what kind of nuts: walnuts, almonds, pecans. Sprinkle them on cereal each morning.” —Gary Fraser, MD, PhD, cardiologist and epidemiologist at Loma Linda University. This is how skipping breakfast can harm your health.


If it sprouts, it’s worth eating

“Nuts, fruit, beans, and whole grains are all rich in phytochemicals and other anti-inflammatory compounds.” —Dariush Mozaffarian, MD, drph, a cardiologist and an epidemiologist who is dean of the Friedman School of Nutrition Science and Policy at Tufts University


Sprinkle your meals with ground flaxseeds

“Filled with fiber and omega-3s, flaxseeds may help protect against heart disease, cancer, diabetes, and cognitive decline and treat the symptoms of rheumatoid arthritis. Grind them up and add to oatmeal, yogurt, pancakes, waffles, salads, soups, sandwich spreads, and more.”—Angie Eakin, MD, MS, a member of the Physicians Committee for Responsible Medicine and a primary care physician who specializes in nutrition at Barnard Medical Center. Check out these easy tips to get more fiber in your diet.


Make wine your alcohol of choice

“One or two drinks a day—wine, and perhaps other alcoholic beverages—may help to lower cholesterol and improve heart and brain health. Don’t hold off all week, then live it up on the weekend. More than two and you likely start to do harm.” —Kenneth S. Kosik, MD, neuroscientist at the University of California, Santa Barbara, and author of Outsmarting Alzheimer’s.


Avoid lunch meats like they’re poisonous

“Processed meats like bacon, ham, hot dogs, lunch meats, and sausage were designated by the World Health Organization as carcinogens in 2015. That means they can cause cancer and are in the same category as asbestos and smoking” (though their risk is not as high). —Michael Greger, MD


Don’t grill; marinate

“A growing body of evidence shows that barbecued meats cooked at high temperatures or over an open flame may increase your risk of cancer. Lower your risk by marinating your meat and minimizing charring.”—Bruce Lee, MD, executive director of the Global Obesity Prevention Center at Johns Hopkins Bloomberg School of Public Health. These are the worst diet advice tips nutritionists have ever heard.


Add your own fruit to plain yogurt

“Plain yogurt that you add whole fruit to is very healthy; it typically has about seven grams of natural sugar. Guess how many grams of sugar in a strawberry yogurt? Depending on the brand, you could have up to 23 grams. That’s not a health food; that’s dessert.” —Robert Lustig, MD, pediatric endocrinologist at the University of California, San Francisco, and author of Fat Chance


Check the sugar counts before buying packaged food

“Of the 85,000 packaged foods in American grocery stores, 74 percent are spiked with added sugar. Sugar alters our hormones so we don’t register hunger normally; it spikes our dopamine, requiring us to eat more sugar for the same effect; and it affects the liver in the same way that alcohol does.” —Robert Lustig, MD. Avoid these common mistakes that could make you regain weight.


Counting calories? Don’t use artificial sweeteners

“In one study, fruit flies that had been accustomed to eating the artificial sweetener sucralose ate 30 percent more calories than those that ate sugar. We believe that because the sweetness in sucralose doesn’t correspond to the calories, the brain compensates by making the animal feel more hungry. This may also happen in humans.” —Greg Neely, PhD, associate professor at the University of Sydney. Here’s what can happen if you stop using artificial sweeteners.

Boxes and bags are bad signs

“The more packaging you have to go through to get to a food, the worse it probably is for you.” —Bruce Lee, MD


Avoid bread to lower your sodium intake

“It doesn’t taste like it, but most bread is filled with salt—it’s one of the top sources of salt in the American diet. If you have high blood pressure, be careful with bread.” —Marc Gillinov, MD, cardiac surgeon at Cleveland Clinic’s Heart & Vascular Institute and coauthor of Heart 411: The Only Guide to Heart Health You’ll Ever Need. Here are the clear signs you’re eating too much salt.


Substitute algae for olive oil

“There’s a new cooking oil made from algae that claims to be even higher in heart-healthy monounsaturated fats than olive oil. Unlike olive oil, it has a neutral flavor and a very high smoke point, so it’s wonderful to cook with. It’s just now getting into stores, but you can order it online for $12 a bottle.” —Keri Gans, RDN, author of The Small Change Diet

Fruits may be better for you than veggies

“People always say to eat your vegetables, but if you look at all the scientific data on long-term health and preventing chronic diseases, fruits have a slightly stronger protective effect than veggies.”—Dariush Mozaffarian, MD, DrPH. Here are the signs your body could be running low on vitamins.


Replace ground meat with mushrooms

“Replacing three ounces of 85 percent lean ground beef with one cup of minced mushrooms cuts almost 200 calories. Mushrooms are also one of the only food-based sources of vitamin D, a key nutrient most people fall short on.” —Cynthia Sass, MPH, RD


Flavor sauces with sardines

“Sardines are loaded with omega-3s, selenium, vitamin D, and high-quality protein. If eating them out of the tin doesn’t appeal to you, add some sardine paste or chopped-up sardines to salad dressing or tomato sauce.” —Kate Geagan, MS, RD


Presoak your potatoes

“Potatoes contain an amino acid that changes into a toxin called acrylamide when exposed to high heat during frying or roasting. Acrylamide makes it tougher for brain cells to communicate with one another. No one knows how much of this toxin the body can safely tolerate, so when possible, boil, steam, or microwave potatoes. If you roast, soak slices in water for 15 to 30 minutes first.” —Kenneth S. Kosik, MD. Here are the disgusting and dangerous things you don’t realize you could be eating.


Healthier food is always in your own fridge

“Every time you go out, you eat about 300 more calories than you would have at home. And restaurant food has much higher levels of sodium, sugar, and saturated fat. To add years to your life expectancy, buy a slow cooker and throw in some beans and vegetables before you head to work; when you come home, you’ll have a healthy dinner.” —Dan Buettner


Ditch the mayo

“Try hummus, tahini, mashed avocado, or olive tapenade in place of mayonnaise on sandwiches and in tuna or chicken salad. All four provide creamy texture and lots of flavor while adding bonus nutrients and heart-healthy fat. They also make great dips for fresh-cut veggies in place of ranch dressing.”—Cynthia Sass, MPH, RD


Try “overnight” oats for a fiber-filled snack

“Combine old-fashioned oats with milk in a Mason jar. Leave it in the fridge overnight, and the oats soak up the milk. The next morning, add mix-ins like fruit, seeds, nuts, honey, peanut butter, or maple syrup. One serving of oats has 40 grams of whole grains and 4 grams of fiber, plus the milk has protein.”—Rebecca Scritchfield, registered dietitian and author of Body Kindness. Here are the signs you need to lower your sugar intake.


Balance your carbs and fiber

“For every ten grams of carbohydrate in a food, there should be at least one gram of fiber.”—Dariush Mozaffarian, MD, DrPH


Spread on avocado instead of butter

“This swap saves calories and adds vitamins, minerals, antioxidants, fiber, and good fats. In brownies or chocolate cakes, the cocoa will mask the green hue of the avocado.” Trade half a tablespoon of avocado for each tablespoon of butter. —Cynthia Sass, MPH, RD. These are more powerhouse benefits of avocado.


Snack on easy-to-make DIY popcorn

“Place kernels inside a brown paper lunch bag. Fold the top down a few times, then microwave for two to three minutes. Voilà. Microwave popcorn without the chemicals and trans fat.” And as snacks go, this one is a real bargain. —Kenneth S. Kosik, MD. Here’s why eating popcorn is surprisingly healthy.


Don’t be afraid of fat

“In one study, we put overweight young adults on a low-calorie diet. After they had lost 10 to 15 percent of their weight, we gave some of them a low-fat diet and the others a low-carbohydrate diet with lots of healthy fats, like olive oil, nuts, seeds, and avocado. On the low-fat diet, their metabolism crashed. On the low-carb, high-fat diet, their metabolism didn’t slow at all.” —David Ludwig, MD, PhD, professor of nutrition at the Harvard T.H. Chan School of Public Health and author of Always Hungry. Check out this guide to understanding the different types of fats.


Drink more water to burn more calories

Small studies show that drinking more water has the potential to boost metabolism. “It takes calories to process water, because everything we do takes calories. The more water, the more calories you need to expend. I suggest aiming for around two liters a day.”—Lauren Harris-Pincus, MS, RDN, founder of


Coffee and green tea can boost metabolism

In a study of eight men, caffeine increased energy expenditure by 13 percent. Even better, “brewed tea also raises metabolism rates. Be careful not to cancel out the health benefits: If you like sugar in your tea, use one teaspoon or less.” —Lisa Stollman, MA, RDN, CDE, CDN, author of The Trim Traveler. Follow these tips to speed up your metabolism.


Spread your protein throughout the day

Most people “can absorb only about 25 to 35 grams of protein at a time for muscle building and repair.” The rest will turn to fat. As a guide, 30 grams is equivalent to five eggs, four ounces of chicken, or 20 ounces of low-fat yogurt. —Lauren Harris-Pincus, MS, RDN


Some things aren’t good in moderation

“What you really want to do is eat more of the good things (fruits, beans, seeds, nuts, etc.) and less of the bad things (processed meats, refined starch, added sugar, trans fats, sugar-sweetened beverages).”—Dariush Mozaffarian, MD, DrPH


Full-fat dairy may be better than low-fat

“Studies suggest that people eating low-fat dairy either gained more weight or were at a higher risk for diabetes and heart disease than those eating equal portions of full-fat dairy.” —David Ludwig, MD, PhD. These are the 13 foods cardiologists try to never eat.


Be wary of the phrase “whole grain”

“Just because a bread or cracker package says ‘made with whole grains,’ it doesn’t mean it’s 100 percent whole grain. In fact, it could be only 1 percent whole grain. Look for the black-and-gold Whole Grain Stamp.” —Sara Baer-Sinnott, president of Oldways, a food education nonprofit


Several small meals only make you eat more

“In some clinical trials, people who are told to eat five or six small meals a day overeat the wrong things five or six times a day. Instead, I recommend two meals a day, plus a snack like a nut bar.” —Valter Longo, PhD, director of the Longevity Institute at the University of Southern California


Pasta actually doesn’t raise blood sugar

“Because pasta is extruded to make shapes, it takes longer to digest, so even though it has the same ingredients as white bread, it doesn’t cause a rapid sugar spike.” Overcooking or overeating pasta, though, will still raise blood sugar. —Sara Baer-Sinnott. These are the 13 “healthy” food habits you should ditch right now.


Organic isn’t the healthiest option

“You may have environmental or economic reasons to look for organic or local foods, but there’s little science showing that these relate to health.” —Dariush Mozaffarian, MD, DrPH


Salt is not the enemy

Salt may be less of a risk than scientists thought. “If you don’t have high blood pressure, you can be more liberal with salt.” Hypertension patients should still follow their doctors’ sodium advice. —Marc Gillinov, MD


Base your diet on carbs

“The cornerstone of every longevity diet in the world is complex carbohydrates: whole grains, brown rice, sweet potatoes, and beans.” —Dan Buttoner. These are the low-carb diet mistakes you should never make.


Eggs don’t really impact cholesterol

“We now know your cholesterol level is determined largely by the mix of fats you eat, not how much cholesterol you eat. So it’s OK to have eggs.” —Marc Gillinov, MD


Stop looking for healthy smoothies

“Many smoothie places use mixes with added sugar, other additives, and no real fruit. Ask what they actually put in their smoothies. Or make one at home.”—Bruce Lee, MD


Shrink your day’s last meal

“Your first meal of the day should be big, whether it’s at 6 a.m. or 10 a.m. Your lunch should be middle-size, and your dinner should be small. A big breakfast fuels your muscles and brain for the day. A small dinner allows digestion to rest overnight and won’t saturate your system with calories your body is more likely to store than to burn.” —Dan Buttoner. Check out these tricks to eating healthy while eating out.


Fast for 12 hours at least twice a week

“If you eat at 7 a.m., make sure you are done eating for the day by 7 p.m. [Intermittent fasting] puts your body into a fasting mode, which small clinical trials and animal studies have shown could slow aging in the brain, help you sleep better, and keep you from gaining weight.” —Valter Longo, PhD


Don’t eat based on one study

“Remember that one study doesn’t make a truth. It takes years and a whole body of evidence before scientists can make a solid nutritional recommendation.” —Sara Baer-Sinnott. These are the eating mistakes even healthy people make.


The origin of your food makes a difference

“We put 20 African Americans on a high-fiber African diet and 20 rural Africans on a low-fiber Western diet. After just two weeks, the biomarkers for cancer risk in the Americans dropped significantly, while those in the Africans jumped significantly.”—Stephen O’Keefe, MD, MSC, gastroenterologist at the University of Pittsburgh


Small diet changes are better than none

“The data shows that some improvement is better than none. Even if you make only one change—drink soda twice a week instead of every day—it will make a difference.”—Teresa Fung, ScD, RD, professor of nutrition at Simmons College. These are the best healthy eating tips from nutritionists.
