10 Everyday Super Foods

By Kathleen M. Zelman, MPH, RD, LD

These easy-to-eat foods are packed with multiple nutrients to help you stay healthy.


If only there were some kind of potion or pill that had everything you needed for weight loss and good health. Unfortunately, no such pill exists, but there is a solution -- something that not only promotes wellness and weight control but tastes good, too. These multitasking "super foods" provide multiple disease-fighting nutrients, fill you up so you can enjoy plenty of food without excess calories, and are easy to include in everyday meals. After all, what good is a super food that is hard to find, difficult to prepare, and the kids won't eat?


Eaten regularly, these foods will help you satisfy the recommendations of the U.S. government's 2005 Dietary Guideline, giving you nutrients that are typically missing from American diets. According to the Guidelines, Americans need to eat more fruits, vegetables, whole grains, and low-fat dairy products.


Of course, experts are quick to point out, this list of top 10 super foods by no means includes all the nutritious foods that should be part of a healthy diet.


"What is ultimately the most important to good health is a dietary pattern that includes all these foods, along with a wide variety of other nutritious foods and regular physical activity," says Tufts University researcher Alice Lichtenstein, DSc.


And don't forget that portion size matters, even when it comes to healthy foods. You can take more liberties when eating simply prepared vegetables, but you should take care to eat other super foods in sensible portions.


"Foods like nuts are nutrient rich, but if you overeat them you can pack on the pounds, and that defeats the purpose," says Elisa Zied, MS, RD, author of Feed Your Family Right!


Top 10 Multitasking Super Foods

1.Low fat or fat-free plain yogurt is higher in calcium than some other dairy products and contains a great package of other nutrients, including protein and potassium. It can also be enhanced with other good-for-you substances. "Yogurt is a vehicle food that can be enriched with probiotics for a healthy balance of bacteria in your gut, and beneficial, heart-healthy plant stanols," says Zied. "And lactose sensitive people may tolerate yogurt better than milk." Look for plain yogurt fortified with vitamin D, and add your own fruit to control sweetness and calories. Versatile yogurt can also be used in entree and bakery recipes, in dips for veggies, etc. Don't like yogurt? Skim milk is another super dairy food that has only 83 calories per cup and is easy to slip into coffee to help you get one of the recommended three servings of dairy each day. "Dairy foods contain practically every nutrient you need for total nutrition -- and in just the right balance," says bone health expert, Robert Heaney, MD. "No other food group in the diet is as complete or as economical."

2.Eggs make the list because they are nutritious, versatile, economical, and a great way to fill up on quality protein. "Studies show if you eat eggs at breakfast, you may eat fewer calories during the day and lose weight without significantly affecting cholesterol levels," says Elizabeth Ward, MS, RD, author of The Pocket Idiot's Guide to the New Food Pyramids. Eggs also contain 12 vitamins and minerals, including choline, which is good for brain development and memory. Enjoy them at any meal or hard-cooked as a portable snack.

3.Nuts have gotten a bad rap because of their high fat content. But their protein, heart-healthy fats, high fiber, and antioxidant content earn them a place on the top 10 list. The key to enjoying nuts, experts say, is portion control. "All nuts are healthful in small doses, and studies show they can help lower cholesterol levels and promote weight loss," says Today Show nutritionist Joy Bauer, MS, RD. "I like pistachio nuts because they also contain plant sterols and it takes longer to crack the shell and eat them, making it easier to control the portion. Whether you prefer pistachios, almonds, peanuts, walnuts, or pecans, an ounce a day of nuts help fill you up. Nuts add texture and flavor to salads, side dishes, baked goods, cereals, and entrees. They taste great alone, too. Zied recommends putting together your own "100-calorie packs" of nuts for easy and portable snacks.

4.Kiwis are among the most nutritionally dense fruits, full of antioxidants, says Ward. "One large kiwi supplies your daily requirement for vitamin C," says Ward. "It is also a good source of potassium, fiber, and a decent source of vitamin A and vitamin E, which is one of the missing nutrients, and kiwi is one of the only fruits that provides it." The sweet taste and colorful appearance of kiwis makes it easy to slice in half, scoop out with a spoon and enjoy alone, or slice it into desserts, salads, or side dishes. Kiwifruit can also have a mild laxative effect due to their high fiber content.

5.Quinoa is now readily available in many supermarkets and is one of the best whole grains you can eat, according to Zied. "It is an ancient grain, easy to make, interesting, high in protein (8 grams in 1 cup cooked), fiber (5 grams per cup) and a naturally good source of iron," she says. Quinoa (pronounced keen-wa) also has plenty of zinc, vitamin E, and selenium to help control your weight and lower your risk for heart disease and diabetes, she says. Quinoa is as easy to prepare as rice and can be eaten alone or mixed with vegetables, nuts, or lean protein for a whole-grain medley. Try to make at least half your daily grain servings whole grains. In addition to quinoa, try barley, oats, buckwheat, whole wheat, wild rice, and millet.

6.Beans, beans, good for your heart -- really! Beans are loaded with insoluble fiber, which helps lower cholesterol, as well as soluble fiber, which fills you up and helps rid your body of waste. They're also a good, low-fat source of protein, carbohydrates, magnesium, and potassium. Bauer favors edamame (whole soybeans) because they also contain heart-healthy omega-3 fatty acids. Beans can easily substitute for meat or poultry as the centerpiece of a meal, says Bauer, but they also work as a side dish, or tossed into soups, stews, or egg dishes. The U.S. Dietary Guidelines recommend 3 cups weekly.

7.Salmon is a super food because of its omega-3 fatty acid content. Studies show that omega-3 fatty acids help protect heart health. That's why the American Heart Association recommends eating fatty fish like salmon twice weekly. Salmon is low in calories (200 for 3 ounces) has lots of protein, is a good source of iron, and is very low in saturated fat. You can simply grill or bake it, top it with salsas or other low-fat sauces, or serve it on top of salad greens. If you don't like salmon, Lichtenstein recommends eating other kinds of fish, like canned tuna. And what about the mercury content? (Mercury is known to accumulate in fish.) "The benefits of eating salmon or other fatty fish twice weekly far outweigh any risks, but if you are concerned, check with your doctor," says Zied.

8.Broccoli is one of America's favorite vegetables because it tastes good and is available all year long. It's a rich source of vitamin A, vitamin C, and bone-building vitamin K, and has plenty of fiber to fill you up and help control your weight. "Some people think beta-carotene (vitamin A) is only found in orange and yellow vegetables, but broccoli is an excellent source," says Ward. You can eat broccoli raw, lightly steamed, stir-fried, roasted, or grilled. Eat it as a side dish, or toss into grains, egg dishes, soups, and salads.

9.Sweet potatoes are a delicious member of the dark orange vegetable family, which lead the pack in vitamin A content. Substitute a baked sweet potato (also loaded with vitamin C, calcium, and potassium) for a baked white potato. And before you add butter or sugar, taste the sweetness that develops when a sweet potato is cooked -- and think of all the calories you can save over that loaded baked potato. "If we eat more foods like sweet potatoes that are rich sources of potassium, and fewer high-sodium foods, we can blunt the effect of sodium on blood pressure and reduce bone loss," says Zied. Other dark orange vegetable standouts include pumpkin, carrots, butternut squash, and orange bell peppers.

10.Berries pack an incredible amount of nutritional goodness into a small package. They're loaded with antioxidants, phytonutrients, low in calories, and high in water and fiber to help control blood sugar and keep you full longer. And their flavors satisfy sweets cravings for a fraction of the calories in baked goods. Blueberries lead the pack because they are among the best source of antioxidants and are widely available. Cranberries are also widely available fresh, frozen, or dried. All can add flavor and nutrition to numerous dishes, from salads and cereals to baked goods and yogurt.

Top 10 Scariest Food Additives

By David Zinczenko with Matt Goulding

There was a time when "fruit flavored" and "cheese flavored" meant "made with real fruit" and "made with real cheese." Today? It's artificial everything. Most of the food at your local supermarket is no more authentic than Snooki's tan. Our fruit comes packaged in Loops, our cheese delivered via Whiz. Sure, it's edible, but there's no way your great grandparents would recognize this junk as food.

The problem with additives runs deep. The FDA currently maintains a list of ingredients called Everything Added to Food in the United States (EAFUS), which features more than 3,000 items and counting. Thankfully, most EAFUS ingredients are benign, but a few of them do have potentially harmful effects. Why they're legal is a mystery to us. Some of them might be backed by powerful lobby groups, while others probably survive simply because some guy at the FDA has too much paperwork on his desk and hasn't made time to adequately review the data.

Below are 10 of the most dubious ingredients hiding in your food, compliments of Eat This, Not That! 2011. Even if you're not convinced of their danger, you have to admit this: The more filler ingredients you cut from your diet, the more space you have for wholesome, nutritious foods.

Scary Ingredient #1: Olestra

A fat substitute synthesized by Procter & Gamble. Because human digestive enzymes can't break down the big molecules, Olestra contributes 0 calories to your diet.

Why it’s scary: In the late ’90s, Frito-Lay released Olestra-enhanced WOW chips and Procter & Gamble introduced Fat Free Pringles. Both products were required to carry warning labels to notify customers about the risk of "loose stools." Within 4 years, some 15,000 people had dialed in to a hotline set up specifically to handle adverse-reaction complaints. Apparently the complaints didn't move the FDA, because in 2003, the administration revoked the warning-label mandate. If you want to take your chances with diarrhea, go ahead, but first consider this: Olestra also appears to interfere with the body's ability to absorb some crucial nutrients like beta-carotene and lycopene. To counteract the effect, processers add some nutrients back, but it's unlikely that all the blocked nutrients are adequetly replaced.

Furthermore, just last week I tweeted that an animal study at Purdue University found that fake fats like Olestra may cause more weight gain than real fat.

Where you’ll find it: Lay’s Light chips, Pringles Light chips

Scary Ingredient #2: Caramel Coloring

An artificial pigment created by heating sugars. Frequently, this process includes ammonia.

Why it’s scary: Caramel coloring shows up in everything from soft drinks and sauces to breads and pastries. When made from straight sugar, it's relatively benign. But when produced with ammonia it puts off 2-methylimidazole and 4-methylimidazole, chemicals that have been linked to cancer in mice. The risk is strong enough that the California government, a bellwether for better food regulation, categorized 4-methylimidazole as “known to cause cancer” earlier this year. Unfortunately, companies aren't required to disclose whether their coloring is made with ammonia, so you'd be wise to avoid it as much as you can.

Where you'll find it: Colas and other soft drinks, La Choy soy sauce, Stove Top stuffing mix

Scary Ingredient #3: Saccharin


An artificial sweetener discovered by accident in the 1870s.


Why it’s scary: Studies have linked saccharin to bladder tumors in rats, and in 1977, the FDA required warning labels on all saccharin-containing foods. In 2000, the agency changed its stance and allowed saccharin to be sold without warning labels. But that doesn't make it entirely safe. A 2008 Purdue study found that replacing sugar with saccharin in rats’ diets made them gain more weight, proving once again that you should be aware of these faux fat foes.

Where you'll find it: Sweet ‘N Low, TaB cola

Scary Ingredient #4: Potassium Bromate

A compound that conditions flour and helps bread puff up during baking.

Why it’s scary: Potassium bromate causes thyroid and kidney tumors in rats, and it's banned from food use in many countries. In California, products containing potassium bromate are required to carry a cancer warning. Fortunately, negative publicity has made the additive relatively rare, but until the FDA banishes it, you should remain on the lookout.

Where you'll find it: Johnny Rockets Hoagie Roll

Scary Ingredient #5: Butylated Hydroxyanisole (BHA) and Butylated Hydroxytoluene (BHT)

Petroleum-derived antioxidants and preservatives.

Why they're scary: The Department of Health and Human Services says BHA is “reasonably anticipated to be a human carcinogen," yet the FDA allows it to be used anyway. BHT is considered less dangerous, but in animal research, it too has resulted in cancer. Oddly, the chemicals aren’t even always necessary; in most cases they can be replaced with vitamin E.

Where you'll find it: Goya lard, Golden Grahams, Cinnamon Toast Crunch, Orbit gum

Scary Ingredient #6: Partially Hydrogenated Vegetable Oil

A semi-solid fat created when food processors force hydrogen into unsaturated fatty acids.

Why it's scary: Partially hydrogenated fats are the principle sources of trans fat in the American diet, and a Harvard study estimated that trans fat causes 70,000 heart attacks every year. The good news: Partially hydrogenated oils are beginning to slowly retreat from our food. Progressive jurisdictions like New York City are starting to restrict the allowable amounts in restaurants, and many chains are switching to healthier frying oil. Still, the battle isn’t over. At Long John Silver’s, for example, there are still 17 menu items with more than 2 grams of the stuff. According to the American Heart Association, that's about the maximum you should consume in a single day.

Where you'll find it: McDonald’s McChicken, Long John Silver’s Broccoli Cheese Soup

Scary Ingredient #7: Sulfites

Preservatives that maintain the color of food, and by releasing sulfur dioxide, prevent bacterial growth.

Why it's scary: Humans have used sulfites to keep food fresh for thousands of years, but some people—especially asthma sufferers—experience breathing difficulties when exposed. In the 1980s, unregulated use resulted in at least a dozen deaths, prompting the FDA to slap warning labels on wine bottles and develop new guidelines for proper use. Now restaurants can no longer soak fresh ingredients in sulfites. According to the Center for Science in the Public Interest, there have been no known deaths since the new legislation took hold. The bottom line: If you're among the majority of people not sensitive to sulfites, consumption won’t hurt you. If you're not sure, ask your doctor for a test.

Where you'll find it: Wine, Sun-Maid Mixed Fruit, Jolly Ranchers, Fig Newtons

Scary Ingredient #8: Azodicarbonamide

A synthetic yellow-orange dough conditioner

Why it's scary: This chemical is used most frequently in the production of industrial foam plastic, and although the FDA has approved its use for food in the States, the United Kingdom has labeled it a potential cause of asthma. In a review of 47 studies on azodicarbonamide, the World Health Organization concluded that it probably does trigger asthmatic symptoms. The WHO concluded, “exposure levels should be reduced as much as possible.” I’ll put it more concisely: Avoid it.

Where you'll find it: Dunkin’ Donuts bagels, McDonald’s burger buns

Scary Ingredient #9: Carrageenan

A thickener and emulsifier extracted from seaweed.

Why it's scary: Seaweed is actually good for you, but carrageenan is a mere seaweed byproduct. Through animal studies, it has been linked to cancer, colon trouble, and ulcers. It isn’t certain that carrageenan harms humans, but avoiding it is clearly the safer option. Most studies examined degraded forms of the additive, and research from the University of Iowa found that carrageenan could be degraded through the normal digestive process.

Where you'll find it: Weight Watchers Giant Chocolate Fudge Ice Cream Bars, Skinny Cow Ice Cream Sandwiches, Creamsicles

Scary Ingredient #10: Ammonium Sulfate

An inorganic salt that occurs naturally near active volcanoes and is used commercially to nourish yeast and help bread rise.

Why it's scary: This nitrogen-rich compound is most often used as fertilizer, and also appears commonly in flame retardants. Thankfully, the ingredient only sounds scary—a 2006 Japanese rat study found the additive to be non-carcinogenic. Both the Center for Science in the Public Interest and the FDA deem it safe.

Where you'll find it: Nature’s Own bread, Subway rolls
