JUST A LITTLE
EGGIE FACTS...
Old News: Don’t eat eggs. A single egg has 215 milligrams of
cholesterol—two-thirds of the daily maximum.
Latest News: Saturated
fat—and eggs contain very little—plays a bigger role in raising blood
cholesterol than dietary cholesterol. A daily egg may have little
effect on the risk of heart disease in healthy people. This does not
include people with high cholesterol levels, or diabetics, or others
with heart disease risk factors. But if you know you’re healthy and
that your cholesterol is at a desirable level, you can eat a daily egg.
YOU SAY TOMATO? WE SAY...
Old News: A good
source of vitamin C, especially fresh tomatoes.
Latest News: Yes,
tomatoes offer vitamin C, and a lot else besides. It turns out that
they are rich in important carotenoids, including lycopene—a relative
of the more celebrated beta-carotene. Lycopene appears to help prevent
prostate cancer. Oddly enough, cooked and processed tomatoes contain lycopene that’s more readily available to the body. Ounce for ounce,
processed tomato products (such as sauce, paste,
or juice) contain 2 to 10 times as much available lycopene as fresh
tomatoes.
THE SHELLFISH GAME...
Old News: Shrimp are
rich in cholesterol and don’t belong in a heart-healthy diet.
Latest News: Shrimp
have more cholesterol than any other shellfish except squid: about 195
milligrams per 3.5-ounce serving (the daily limit is 300 milligrams). But the cholesterol in shrimp may not be as much of a problem as
cholesterol in other foods. And shrimp are very low in saturate
fat—only 0.3 grams in that serving. Saturated
fat, more than dietary cholesterol, raises blood cholesterol. In
addition,
shrimp contain heart-healthy omega-3 fatty acids. Further news: Many
shellfish,
such as crabs, scallops, mussels, clams, and lobster, are actually
slightly
lower in cholesterol than chicken or beef.
ORANGE YOU GLAD YOU ASKED...
Old News: Citrus
fruits contain lots of vitamin C.
Latest News: The
vitamin C is still there. But oranges, grapefruits, lemons, and limes
also contain a wide range of important phytochemicals that may help
protect against cancer and stroke.
CHERRIES, BLUEBERRIES, BEETS, PEPPERS...
Old News: Good food,
but no better than lighter-colored fruits and vegetables.
Latest News: Deeply
colored fruits and vegetables tend to have the most vitamins and
minerals. And besides that, the plant pigments that give them such rich
colors may themselves protect against chronic diseases, including
cancer. These pigments have high antioxidant potential. This doesn’t
mean you shouldn’t bother with cauliflower, green grapes, or white
potatoes. But do include some of the “darks”—such as kale, spinach,
prunes, red grapes, raisins, cherries, oranges, and carrots—every day.
