Tomatoes are actually a type of berry, and were called “love apples” in the 16th century
Varieties
include baby plum, beefsteak, cherry, plum, vine, and yellow cherry
Equally delicious raw or cooked, tomatoes are low in calories and rich in vitamins and other
healthful substances
One medium-size ripe tomato contains only 26 calories, together with about 23
mg of vitamin C and 20 mcg of folate
Tomatoes, like potatoes, sweet peppers, and eggplants, belong to the nightshade family
Brought to
Europe from Central America by the Spanish during the 16th century, tomatoes were grown as
decorative plants in northern Europe, where it was feared that the poisons in the leaves might be
present in the fruit as well
Colonists emigrating from that area imported this misconception to the
New World
Meanwhile, the Spanish and Italians discovered that tomatoes were indeed edible, and
as they immigrated to North America, they brought their taste for tomatoes with them
Today, the
tomato is one of the world’s leading vegetable crops, although botanically the tomato is a fruit
TOMATO FACT
Lycopene, the powerful antioxidant in tomatoes, is fat-soluble
So adding a little olive oil or other healthy
fat to tomato dishes increases absorption
Health Benefits
Helps prevent cancer
A well-known Harvard study showed that men who regularly ate tomato-
based foods had lower rates of prostate cancer
Researchers theorize that lycopene—a powerful
antioxidant—is the natural cancer-fighting agent in tomatoes
The best way to get lycopene is in
tomato sauce, tomato paste, tomato juice, and even ketchup
Lycopene is most concentrated in tomato
paste
Tomatoes also contain a compound called chlorogenic acid, which may help guard against
cancer by blocking the effects of certain environmental toxins—for instance, nitrosamines, cancer-
causing compounds in tobacco smoke and cured meat
Prevents heart disease
The jellylike substance surrounding tomato seeds is high in salicylates,
which have an anticlotting effect on the blood
This may be partially responsible for tomatoes’
protection against heart disease
Researchers also are finding that lycopene plays a role in heart
health, lowering LDL cholesterol, increasing activity of the antioxidant enzyme superoxide dismutase
(SOD), and reducing in DNA damage in white blood cells
50% more lycopene is contained in a Crimson type of tomato vs
a
regular tomato
Health Risks
Digestive distress
An unidentified substance in tomatoes and tomato-based products can cause acid
reflux, leading to indigestion and heartburn
People who often have digestive upsets should try
eliminating tomatoes for 2 or 3 weeks to see if there is any improvement
Allergies
Tomatoes are a relatively common cause of Allergies
Headaches
Solanines are toxic substances present in minute quantities in all members of the
nightshade family: They may trigger headaches in susceptible people
Canker sores
Tomatoes can make these mouth sores even more painful
Allergies
Add sliced tomatoes to a breakfast egg sandwich
Bake sliced tomatoes, breadcrumbs, parmesan and garlic into a ready-made pie crust
Stuff tomatoes with tuna salad
Buying Tip
s
Choose fresh tomatoes that are a deep red color for highest lycopene content
Vine-ripened tomatoes have more lycopene than those that are picked early and allowed to ripen off the
vine
So it makes sense to grow your own tomatoes or buy from a local farmers’ market
Choose canned or jarred tomatoes with reduced or no sodium added
Storing Tips
Ripe tomatoes should be stored at room temperature
At 40°F (4°C) or below, the flesh becomes mealy
Store unopened canned, jarred, or tetra-pack tomatoes in a cool cupboard for up to 1 year
