Foods for Men
1.Tomatoes. Men who eat a lot of tomatoes, tomato sauce, or pizza
smothered with the stuff may be giving themselves a hedge against
prostate cancer. So say researchers at Harvard, who studied the eating
habits of more than 47,000 male health professionals. They found that
men who ate tomato sauce two to four times per week had a 35 percent
lower risk of developing prostate cancer than men who ate none. A
carotenoid called lycopene, which tomatoes contain in abundance,
appeared to be responsible. But scientists were puzzled: tomato juice
didn't seem to have a protective effect. Other research showed why. For
best absorption, lycopene should be cooked with some kind of fat. So
pizza may be just what the doctor ordered.
2. Oysters. Myth has it that oysters are the food of love. Science
may agree. Just two to three oysters deliver a full day's supply of
zinc, a mineral critical for normal functioning of the male reproductive
system. Scientists are divided over reports that sperm counts have
declined over the last 50 years and that environmental factors are to
blame. Nutritional deficiencies do seem to be the cause of certain cases
of low testosterone. Getting adequate zinc is sometimes the answer (11
mg per day is recommended for men; more than 40 mg can pose risks). In
one trial, 22 men with low testosterone levels and sperm counts were
given zinc every day for 45 to 50 days. Testosterone levels and sperm
counts rose.
3. Broccoli. A recent Harvard study finds that cruciferous
vegetables, like broccoli, may protect against bladder cancer. It's one
of the most common cancers in this country, and affects two to three
times as many men as women. Scientists analyzed the diets of nearly
50,000 men and discovered that those who ate five servings or more per
week of cruciferous veggies were half as likely to develop bladder
cancer over a ten-year period as men who rarely ate them. And broccoli
and cabbage were singled out as the most protective foods.
4. Peanut Butter. If you want a healthy heart, spread your morning
toast with peanut butter. Heart disease is the leading killer of men and
women, but men fall victim at an earlier age. Researchers from
Pennsylvania State University compared the cholesterol-lowering effect
of the American Heart Association's Step II Diet with a higher-fat diet
based on peanuts. The AHA plan included more carbohydrates. The peanut
regimen was 36 percent fat. After 24 days both diets lowered "bad" LDL
cholesterol. But the peanut plan also caused a drop in blood fats called
triglycerides and did not decrease HDL, the "good" cholesterol. The AHA
diet raised levels of triglycerides and lowered levels of HDL.
"Peanut butter is a little higher in fat," says Penny Kris-Etherton,
Ph.D., the lead author of the Penn State study. "But it's the type
that's good for you -- monounsaturated fat." Researchers have predicted
that the peanut diet could reduce heart-disease risk even more than
could the AHA diet. Just don't go nutty plastering on the tasty spread,
since it is high in calories.
5. Watermelon. Until the age of 55, more men suffer from high blood
pressure than do women. Research suggests that foods rich in potassium
can reduce the risk of high blood pressure and stroke. The evidence is
so convincing that the Food and Drug Administration recently allowed
food labels to bear a health claim about the connection between
potassium-rich foods and blood pressure. "There isn't a dietary
requirement for potassium," says Kathleen Cappellano,
nutrition-information manager at Tufts University in Boston. "But a good
goal is about 2000 milligrams or more a day." Watermelon, a rich source
of this mineral, has more potassium -- 664 mg -- in one large slice
than the amount found in a banana or a cup of orange juice. So cut
yourself another slice and enjoy the taste of summer.
Foods for Women
1. Papaya. This tropical fruit packs about twice the vitamin C of an
orange. Add it to your arsenal against gallbladder disease, which
afflicts twice as many women as men.
After analyzing the blood of over 13,000 people, scientists from the
University of California, San Francisco, found that women who had lower
levels of vitamin C were more likely to have gallbladder illnesses. One
medium papaya (about ten ounces), with its 188 mg of vitamin C and a
mere 119 calories, is a refreshing source of the vitamin. The once
exotic fruit now can be found in most supermarkets.
2. Flaxseed. Bakers use this nutty-flavored seed mainly to add flavor
and fiber. But scientists see the tiny reddish-brown seed, rich in
estrogenlike compounds called lignans, as a potential weapon against
breast cancer. An exciting report at last year's San Antonio Breast
Cancer Symposium showed that adding flaxseed to the diet of women with
breast cancer effectively slowed tumor growth. You can flavor your
muffins with flaxseed, but the easiest way to get the beneficial lignans
is to sprinkle a few tablespoons of ground flaxseed on your morning
cereal. Look for the seeds in health food stores or in supermarkets on
the flour aisle. They're easy to grind in a blender or coffee grinder.
But get seeds -- there are no lignans in the oil.
3. Tofu. Foods high in soy protein can lower cholesterol and may
minimize menopausal hot flashes and strengthen bone. Isoflavones, plant
chemicals in soybeans that have a structure similar to estrogen, may be
the reason. Though animal studies form the bulk of the evidence, a human
study found that 90 mg of isoflavones was beneficial to bone
(specifically the spine). And two other studies suggest that 50 to 76 mg
of isoflavones a day may offer some relief from hot flashes. A half-cup
of tofu contains about 25 to 35 mg of isoflavones.
4. Collard Greens. This humble vegetable may help fight osteoporosis,
which afflicts many women late in life. In addition to getting adequate
amounts of calcium and vitamin D, some studies suggest that vitamin K
may have a bone-protective effect as well. Based on data from one of the
largest studies of women, the Nurses' Health Study, researchers
discovered that women who ate enough vitamin K-rich foods (at least 109
micrograms of the vitamin daily) were 30 percent less likely to suffer a
hip fracture during ten years of follow-up than women who ate less.
Researchers point out that dark-green leafy vegetables -- Brussels
sprouts, spinach, broccoli -- are all good sources of the vitamin. But
collard greens, with about 375 micrograms per half-cup, are among the
best.
