Have you seen the magazine ads about ketchup - our
favorite source of lycopene? What is lycopene, what does it do, why do you
need it and where can you get it?
Named the 1997 Vegetable of the Year by Eating Well magazine, tomatoes are
receiving a lot of attention and promotion now because lycopene, an
antoxidant, may help lower the risk of prostate cancer, perhaps other
cancers, and lower the risk of heart disease. Researchers at the Harvard
School of Public Health and Harvard Medical School studied more than
47,000 men and discovered those who ate tomato products 10 or more times a
week. had less than one-half the risk of developing prostate cancer. In
that study, most of the lycopene came from tomatoes, tomato sauce, tomato
juice and pizza. Although the exact mechanism isn't known, lycopene
appears to efficiently quench single oxygen molecules which when left
unchecked initiate various disease processes. Heart disease, for example,
is thought to begin when LDL ("bad" or low-density) cholesterol is
oxidized.
Former President Reagan, who attempted to classify ketchup as a vegetable
to the horrors of nutritionists, must be having a laugh now. Processed
tomato products, including ketchup, sauce, paste, juice, soup, salsa and
canned tomatoes, all contain various amounts of lycopene, a carotenoid
responsible for the fruit's deep red color. (Other red/pinkish fruits -
watermelon, pink grapefruit - also contain lycopene.) Cooking breaks down
the plant's cell walls releasing lycopene, so processed tomato products
have more lycopene than fresh tomatoes. Comparisons in ads only show how
tomato products compare to each other in lycopene not to a Daily Value
because no Daily Value or RDA exists for antioxidants such as lycopene.
Without a Daily Value for antioxidants and because
Nutrition Facts labels do not list antioxidants such as lycopene, good
advice is to enjoy tomatoes and tomato products in a variety of dishes and
meals. In addition to lycopene, tomatoes provide vitamin C and are
naturally low in fat, sodium and calories. Processed tomato products are
convenient and versatile, but have more sodium and calories than fresh
tomatoes. Consider, too, how you eat foods and what works for you. It
might be more reasonable, for example, to eat 1/2 cup to 1 cup of tomato
sauce on an entree size pasta dish than frequently eating smaller portions
of condiments. The health connection appears to be associated with
lycopene rich foods in general. No one food or condiment is going to be
able to go it alone when it comes to providing all the benefits you get
from a varied diet.
