Today, science has a
better understanding of why fruits and vegetables should be part of
a healthy eating plan. You probably enjoy them for their wonderful
flavors and bright colors. But, fruits and vegetables are good for
you too. An eating pattern packed with plenty of fruits and
vegetables includes two to three servings of fruits and three to
five servings of vegetables each day. Fruits and vegetables provide
important nutrients including antioxidants such as vitamin C,
vitamin E, beta-carotene and lycopene.

Antioxidants have disease-fighting properties
that protect cells from damage by substances called free radicals.
Antioxidants work by neutralizing free radicals that are formed when
body cells burn oxygen for energy. Antioxidants also may help keep
the immune system healthy and reduce the risk for cancer and other
diseases.
What is lycopene?
One antioxidant in particular has received a lot of attention from
researchers in recent years. Lycopene is a pigment that gives
vegetables and fruits, such as tomatoes, pink grapefruit and
watermelon, their red color. It also appears to have strong
antioxidant capabilities. Several studies suggest that consumption
of foods rich in lycopene is associated with a lower risk of
prostate cancer and cardiovascular disease.
In a 1995 Harvard University study conducted
with 47,894 men, researchers found that eating 10 or more servings a
week of tomato products was associated with a reduced risk of
prostate cancer by as much as 34 percent.
The protective effect of antioxidants on heart
disease has been well documented. In a recently published study, men
who had the highest amount of lycopene in their body fat were half
as likely to suffer a heart attack as those with the least amount of
lycopene in their body fat. Researchers have determined that the
level of lycopene in body fat is an indicator of lycopene content in
the diet.
Where do I find lycopene?
Lycopene is not produced in the body, so you can only obtain its
benefits by eating foods rich in lycopene. Tomato products, such as
spaghetti sauce, tomato juice, ketchup and pizza sauce are, by far,
the major sources of lycopene in the typical American diet. In fact,
these foods provide over 80 percent of the lycopene consumed in the
U.S. Other fruits and vegetables such as watermelon and pink
grapefruit also provide lycopene but in smaller amounts.
Lycopene is better absorbed by the body when
it is consumed in processed tomato products, rather than fresh
tomatoes. The reason for this remains unclear. In one study lycopene
was absorbed 2.5 times better from tomato paste than from fresh
tomatoes. However, cooking fresh tomatoes with a little oil greatly
increases lycopene absorption.
Convenient ways to increase your consumption
of lycopene:Now that you know about
the potential health benefits from eating foods rich in lycopene,
try some of the following tips to add it to your diet:
2 tablespoons vegetable oil
2 medium zucchini, sliced
2 garlic cloves, minced
1 can (14.5 oz.) diced tomatoes with sweet onions
2 tablespoons tomato paste
1/2 teaspoon Italian seasoning
1 pound frozen, prepared jumbo cheese or meat ravioli, cooked,
drained, kept warm
Fresh grated Parmesan cheese (optional)
Steps to prepare:
1. HEAT oil in a
medium saucepan over medium-high heat. Add zucchini and garlic; cook
about 5 minutes stirring frequently until zucchini is tender.
2. STIR in
tomatoes, tomato paste and seasoning. Simmer over low heat,
uncovered, for 10 minutes.
3. POUR about 3
cups of the zucchini-tomato sauce on serving platter. Place ravioli
over it then top with remaining sauce. Garnish with Parmesan cheese,
if desired.
