Superfoods
By KELLY BOTHUM
We’re supposed to treat our body like a temple, but for many of us it’s more like a flophouse. We work too long, sleep too little and try to make up the difference with too much caffeine. We supersize our fries and downsize our veggies. And the only exercise many of us get is running from the house to the car so we can sit in traffic on the way to the office.
Is it any wonder, then, that when we hear about the latest miracle foods that can help undo some of the damage we inflict on ourselves, we jump on them like fleas on a shaggy dog?
But the good news is that many of these so-called wonder products actually may do some of the things they promise. Pomegranates and mangosteen contain antioxidants, which help the body rid itself of free radicals — molecules that damage cells and may play a role in serious health problems such as heart disease and cancer. Fish oils are a source of heart-healthy fatty acids. Even honey has been touted for its protective powers.
We can do ourselves a favor by consuming some of these products, but we can’t expect a few cups of green tea to make up for the fatty burger we eat four days a week.
“People want a quick fix. You have to look at everything in your life, not just one or two foods,” says Kim Westcott, a registered dietitian at Beebe Medical Center in Lewes, Del.
Here’s a look at some of these miracle foods and their benefits and what to consider when incorporating them into our diet:
Green tea
What it does: Made from leaves that are steamed after they are picked, green tea has a reputation for having the most antioxidants called polyphenols. Antioxidants are like the body’s bounty hunter — they scavenge the body for free radicals. It’s believed that free radicals contribute to aging as well as health problems. Polyphenols neutralize free radicals before they can damage cells.
Research also shows that green tea lowers total cholesterol and increases HDL cholesterol (“good” cholesterol) in animals and people.
What to watch out for: Because it has caffeine, green tea is a good substitute for coffee. But if you drink it, make the tea yourself rather than buying a watered-down version sold in stores. And don’t dump in a lot of sugar, advises Dr. Gerald Lemole, the medical director of the Christiana Care Center for Integrative Health. Doing that increases the production of white cells by the immune system, increasing inflammation in the body.
Flaxseed
What it does: For being a tiny seed, flaxseed can do a lot. It’s a non-fish source of omega-3 fatty acids, which can help reduce total blood cholesterol and the risk of heart disease.
Flaxseed, which contains phytochemicals called lignans, also is a good source of fiber, which is important because most Americans usually get only about half of the recommended 28 grams of fiber a day.
Most health experts advise people to grind the whole seed and sprinkle it over salad or cereals. Flaxseed also can be used in place of eggs when baking cookies, breads and cakes, although it alters the texture.
What to watch out for: Flaxseed oil also is an option but it doesn’t have the added fiber that the seed has, Westcott says.
Tomatoes
What they do: Tomatoes are rich in lycopene, another antioxidant good at fighting free radicals. Some research suggests that lycopene could help prevent prostate cancer.
In addition to its antioxidant powers, a typical serving of tomatoes also provides about 40 percent of the recommended daily allowance of vitamin C and 20 percent of vitamin A.
What to watch out for: Cooked tomatoes actually have more lycopene than raw ones do.
Soy
What it does: Soy protein has been credited with decreasing LDL cholesterol — the “bad” one. Soy also has isoflavones, which are phytoestrogens and antioxidants.
Westcott, the dietitian, says breast cancer patients or women at risk of breast cancer are encouraged to eat whole soy foods rather than take supplements.
It provides a good amount of protein and fiber in a diet, and it can also replace higher-fat foods, particularly those with saturated fats.
What to watch out for: Debate continues about whether soy — and particularly, isoflavones supplements — are as good for women as they were once touted to be.
Other ‘wonder’ foods
There are plenty of superfoods out there, known for their nutrient density and healing qualities. Here are a few other popular ones:
Honey: There’s been a buzz about honey lately, as people credit it with helping to heal wounds, boost energy and improve memory. Raw honey has been noted for its ability to fight off germs and bacteria.
Chili peppers: A 2006 study in a nutrition journal found that consuming chili peppers reduces the amount of insulin in the blood after eating.
Fish oil: Whether taken as a supplement or from the consumption of fatty fish, such as salmon, fish oil is an excellent source of omega-3 fatty acids. These acids lower triglycerides and reduce the risk of heart attack and stroke in people with cardiovascular disease.
Sprouts: Broccoli sprouts have sulforaphane, which has been found to help fight age-related blindness. Mung bean sprouts are a good source of vitamin C, which aids in wound healing and in keeping bones and teeth strong. But be sure to buy them from a reputable place and wash them completely before eating. They can harbor dangerous bacteria from the ground.
Blueberries: Like other foods with antioxidants, blueberries can help neutralize free radicals. That is because they contain anthocyanidins, which also gives the berries their deep color. In general, says Westcott, the darker the color, the more nutrients a fruit or vegetable has.
