Eaten many coconuts lately? How about cherries or blueberries or grass-fed beef?

You should, because these are all foods with powerful health properties. However, few people pack their grocery carts full of these items.

Take kiwifruit. It’s chock full of vitamin C–a whopping 115% of what you need to eat in a day. It’s also low in calories–just 45 per fruit, sans skin.

“In America, most people don’t eat three servings of fruit and vegetables a day,” says nutritionist Jonny Bowden, author of seven books including, most recently, The 150 Most Effective Ways to Boost Your Energy. According to him, there are 10 very healthy foods we don’t eat enough of.

Ignore the Food Pyramid

Bowden says many Americans are misled by the U.S. Department of Agriculture’s food pyramid, which is a graphic, pyramid-shaped depiction of nutrition guidelines, updated every five years, that tells Americans what to eat according to food groups. Bowden dismisses it as the product of interest group politics.

“It demonizes fat,” notes Bowden. “Fat is an essential building block for many important compounds in the body.” This is why Bowden puts grass-fed beef, wild salmon and, yes, coconuts, on his top 10 list.

Salmon, in particular, is loaded with omega-3 fatty acids, which are associated with heart and brain health as well as bringing down blood pressure and triglycerides, a risk factor for heart disease. Omega-3s have also been found to improve mood and reduce inflammation, says Bowden.

Another food packed with nutritional value that’s present–but not necessarily front and center in every grocery store–is kale. A member of the cabbage family, which Bowden dubs “vegetable royalty,” kale contains indoles, a compound found to fight cancer. Kale is also rich in antioxidants, which also help prevent cancer, says Bowden.

If that’s not enough for you, kale is also full of sulforaphane, yet another cancer-prevention agent. Kale has calcium, iron and vitamins A, C and K, and two nutrients that are great for the eyes, including zeaxanthin. Kale’s pièce de résistance: Two cups packs three grams of fiber. Try sautéing it with garlic and butter, recommends Bowden. Or eat it like salad, with pine nuts, cranberries and olive oil.

Then there are coconuts, a terribly misunderstood food, according to Bowden. The fat in coconuts is a particular kind that’s good for you. It’s called MCT, or Medium-Chain Triglycerides. The body doesn’t store MCT as fat, says Bowden, but rather uses it as energy, like a carbohydrate. Coconuts are also high in lauric acid, a fatty acid that tends to kill pathogens. In addition, coconut oil is great for cooking since it has a very high smoke point.

Eat Mediterranean

For Bowden, sticking to a Mediterranean-style diet is the healthiest way to eat. That means plenty of fruits and vegetables, whole grains, fish, and lots of olive and nut oils. The Mediterranean diet has indeed been proved by study after study to have multiple healthful properties.

If all that sounds just too darn healthy, consider the 10th food on Bowden’s list: dark chocolate. Rich with a phytochemical called flavanol, found by a 2005 study in the Journal of the American College of Cardiology to improve cardiovascular health, chocolate with at least 60% cocoa content should be a regular on your shopping list.

Chocolate and coconut anyone? OK, but not until you’ve finished your kale.

1. Produce

Piling your plate with fruits and vegetables is a no-brainer when it comes to weight loss — they’re low in calories, high in nutrients, and filling — but the latest studies show that certain ones can provide surprising anti-aging benefits.

There’s buzz about blueberries, for instance, for their memory-boosting potential. But berries of all hues are antioxidant-rich, reports Navindra P. Seeram, Ph.D., assistant professor at the University of Rhode Island College of Pharmacy in Kingston. That means they combat free radicals, molecules that can cause widespread cell damage and are linked to chronic inflammation. Unlike the inflammation that occurs when you sprain an ankle or strain a muscle, the type that contributes to aging is persistent, and thought to be at the root of most chronic diseases, from cancer, heart disease, and diabetes to Alzheimer’s, arthritis, and osteoporosis. Berries’ beauty bonus: They’re chock-full of vitamin C, another potent antioxidant that may help keep your complexion looking smooth by fighting those pesky (skin-damaging) free radicals.

To keep your vision sharp, set your sights on spinach and other dark leafy greens. These veggies are prime sources of lutein and zeaxanthin, plant pigments that protect your eyes from the harmful effects of ultraviolet light. Leafy greens are also rich in vitamin K, a nutrient that plays a role in reducing bone loss and preventing fractures.

2. Protein (Try these One-Dish Dinners)

This key dietary component becomes even more critical starting in the 40s, when muscle mass begins to decline by up to 1 percent a year. That drop slows metabolism, which makes the pounds pile on more easily. The double whammy consequence: Added weight puts your health at risk, and down the road, diminished muscle mass can throw off your balance (upping chances of a fall), sap your strength, and even threaten your ability to recover from an illness or accident.

To hang on to your metabolism-boosting muscle — and keep you feeling full after meals (another protein plus) — experts recommend eating plenty of skinless chicken and turkey breast, lean beef and pork, eggs, beans, and seafood. And don’t forget protein-rich dairy: Minerals (primarily calcium, phosphorus, and potassium) in fat-free milk and yogurt as well as low-fat cheeses help to keep blood pressure healthy, pudge in check, and bones strong. News flash: Calcium can’t build bone if you’re not getting enough protein, and current recommendations — about five ounces a day for a 145-pound woman — are too low, says Robert P. Heaney, M.D., professor of medicine at Creighton University in Omaha. Our Anti-Aging Meal Plan provides about 11 ounces of protein daily.

Another reason to spoon up some yogurt: Eating at least 1/4 cup every day led to a 60 percent lower risk of gum disease and a 50 percent lower risk of tooth loss in a Japanese study published in the Journal of Periodontology. The effect is thought to be linked to the probiotics in yogurt, but not in most other dairy.

3. Omega-3-Rich Fish

Fatty acids in seafood help quench the flames of chronic inflammation. In addition, “there’s very good new data suggesting that omega-3 fats from fish act on an area of the brain that leads to improved mood and attitude among healthy people,” says Artemis P. Simopoulos, M.D., author of The Omega Diet. These improvements in outlook lead to feeling healthier and more vigorous, she explains. The omega-3s in fatty fish like salmon and tuna have the most potent anti-inflammatory effects. But it’s smart to consume omega-3s from plant sources, like walnuts and flaxseed, too — especially if you’re not fond of fish.

You probably know already that a diet based on fruits, vegetables, whole grains, and “healthy” fats will provide lots of health benefits, but such a diet can also improve memory. Research indicates that certain nutrients nurture and stimulate brain function.

B vitamins, especially B6, B12, and folic acid, protects neurons by breaking down homocysteine, an amino acid that is toxic to nerve cells. They’re also involved in making red blood cells, which carry oxygen. (Best sources: spinach and other dark leafy greens, broccoli, asparagus, strawberries, melons, black beans and other legumes, citrus fruits, soybeans.)

Antioxidants like vitamins C and E, and beta carotene, fight free radicals, which are atoms formed when oxygen interacts with certain molecules. Free radicals are highly reactive and can damage cells, but antioxidants can interact with them safely and neutralize them. Antioxidants also improve the flow of oxygen through the body and brain. (Best sources: blueberries and other berries, sweet potatoes, red tomatoes, spinach, broccoli, green tea, nuts and seeds, citrus fruits, liver.)

Omega-3 fatty acids are concentrated in the brain and are associated with cognitive function. They count as “healthy” fats, as opposed to saturated fats and trans fats, protecting against inflammation and high cholesterol. (Best sources: cold-water fish such as salmon, herring, tuna, halibut, and mackerel; walnuts and walnut oil; flaxseed and flaxseed oil)

Because older adults are more prone to B12 and folic acid deficiencies, a supplement may be a good idea for seniors. An omega-3 supplement (at any age) if you don’t like eating fish. But nutrients work best when they’re consumed in foods, so try your best to eat a broad spectrum of colorful plant foods and choose fats that will help clear, not clog, your arteries. Your brain will thank you!

A few weeks ago I was using my flat iron and when I looked in the mirror to admire my ’do, I discovered my first gray hair (gasp!). It was the first time I was visibly confronted with the reality that, surprise, I will age, and I’m not 18 anymore no matter how good I feel.

I already have the exercise part down, so on my quest for a fountain of youth I’m paying more attention to research on how to eat to age healthfully. The best information I’ve found? 7 anti-aging super foods and recipes to enjoy them in, from Peter Jaret’s James Beard Foundation award-winning article in EatingWell Magazine, “The Search for the Anti-Aging Diet.”

Read on to find out more about the 7 foods to keep you young:

Chocolate
The Kuna people of the San Blas islands, off the coast of Panama, have a rate of heart disease that is nine times less than that of mainland Panamanians. The reason? The Kuna drink plenty of a beverage made with generous proportions of cocoa, which is unusually rich in flavanols that help preserve the healthy function of blood vessels. Maintaining youthful blood vessels lowers risk of high blood pressure, type 2 diabetes, kidney disease and dementia.

Blueberries
In a landmark study published in 1999, researchers at Tufts University’s Jean Mayer Human Nutrition Research Center on Aging fed rats blueberry extract for a period of time that in “rat lives” is equivalent to 10 human years. These rats outperformed rats fed regular chow on tests of balance and coordination when they reached old age. Compounds in blueberries (and other berries) mitigate inflammation and oxidative damage, which are associated with age-related deficits in memory and motor function. Eat more blueberries with healthy blueberry recipes.

Fish
Thirty years ago, researchers began to study why the native Inuits of Alaska were remarkably free of heart disease. The reason, scientists now think, is the extraordinary amount of fish they consume. Fish is an abundant source of omega-3 fats, which help prevent cholesterol buildup in arteries and protect against abnormal heart rhythms. Eat some tonight with a healthy fish recipe.

Nuts
Studies of Seventh-Day Adventists (a religious denomination that emphasizes healthy living and a vegetarian diet) show that those who eat nuts gain, on average, an extra two and a half years. Nuts are rich sources of unsaturated fats, so they offer benefits similar to those associated with olive oil. They’re also concentrated sources of vitamins, minerals and other phytochemicals, including antioxidants.

Wine
Drinking alcohol in moderation protects against heart disease, diabetes and age-related memory loss. Any kind of alcoholic beverage seems to provide such benefits, but red wine has been the focus of much of the research. Red wine contains resveratrol, a compound that likely contributes to its benefits-and, according to animal studies, may activate genes that slow cellular aging.

Olive Oil
Four decades ago, researchers from the Seven Countries Study concluded that the monounsaturated fats in olive oil were largely responsible for the low rates of heart disease and cancer on the Greek island of Crete. Now we know that olive oil also contains polyphenols, powerful antioxidants that may help prevent age-related diseases.

Yogurt
In the 1970s, Soviet Georgia was rumored to have more centenarians per capita than any other country. Reports at the time claimed that the secret of their long lives was yogurt, a food ubiquitous in their diets. While the age-defying powers of yogurt never have been proved directly, yogurt is rich in calcium, which helps stave off osteoporosis and contains “good bacteria” that help maintain gut health and diminish the incidence of age-related intestinal illness.
