Benefits of a Variety of Fruits and Vegetables

We know we need to eat a minimum of 5
servings of fruit and vegetables everyday. Actually now, to prevent
cancer, 8 to 13 servings per day are recommended. A serving is one cup of
raw fruits or vegetables, or ˝ cup cooked. At a recent lecture I asked a
lunch audience to raise their hand if they had at least one fruit or
vegetable already that day. No one in that group raised their hand. This
is not uncommon. Our processed and convenience foods contain very few
fruits and vegetables.
To prevent chronic diseases, fruits and
especially vegetables are very important. Vegetables especially have the
antioxidants, minerals, and phytochemicals in the correct combination that
help keep the blood sugar in balance, create better energy in the body,
and along with fruits build up the immune system.
Each color found
in fruits and vegetables focus on building the immune system in its own
way. It is important to get a variety of colors, so that you will get a
full range of phytochemicals (beneficial plant chemicals) in your daily
diet. Research is finding that eating whole fruits and vegetables gives
you many more nutrients than you could possible add to a vitamin and
mineral supplement. There are over 12,000 phytochemicals, and I have yet
to see a supplement, unless it has whole fruits and vegetables in it, have
all of the 180 different vitamins or minerals that are required by our
body to function daily.
The different colors in fruits and
vegetables help our immune system react to different stresses in our daily
life. So look at the different colors in your diet. See if they include
each of the colors listed below. This is one way to know that you are
getting the full benefit of nutrients possible in your diet.
Green
Foods – broccoli, kale, leaf and romaine lettuce, spinach, cabbage and
Brussels sprouts. Green foods are especially good for the circulatory
system. They contain many minerals and B-complex vitamins. Some
phytochemicals found in green foods are sulforaphane and indoles that are
very powerful anti-cancer compounds. Researchers have tried to use these
as isolated phytochemicals but find that they only work while in the whole
food form.
Red Foods – tomatoes, watermelon, red cabbage. Red
foods contain many phytochemicals that reduce free radical damage. The
phytochemical called lycopene is especially helpful to prevent prostate
problems, and reduce the effects of sun damage on the skin. Lycopene is
the phytochemical that make the red foods get their red color.
Orange Foods – carrots, pumpkin, squash, sweet potatoes, apricots,
cantaloupe. The orange foods have the carotenoids the help prevent
cancer by repairing the DNA. As our mothers told us, carrots, and other
orange foods, are especially good for our eyes, and help with night
vision. The deep orange foods help our bodies get the vitamin A we need,
without getting excess that can lead to osteoporosis.
Green/Yellow
Foods – yellow corn, green peas, collard greens, avocado and honeydew
melon. This combination of green and yellow foods contains the
carotenoids lutein and zeaxanthin that help reduce the risk of developing
cataracts and macular degeneration. These foods are also helpful in
reducing the risk of osteoporosis.
Orange /Yellow Foods – oranges,
pineapple, tangerines, peaches, papaya, nectarines These foods that
are orange and yellow in color are high in antioxidants, especially
Vitamin C, and help to improve the health of the mucus membranes and
connective tissue. They help prevent heart disease by improving
circulation and preventing inflammation.
White/Green Foods –
onions, garlic, celery, pears, chives White and green combination
foods contain a variety of phytochemicals. Garlic and onions contain
allicin, the anti-viral, anti-bacterial, and anti-fungal phytochemical,
and they can act as a poor man’s antibiotic. Add garlic and onions in your
meals to reduce the effects of potential toxicity of high fat meats.
Celery has many minerals, especially organic sodium, that keeps the fluid
in the joints healthy.
Red/Blue/Purple Foods – red apples, beets,
blueberries, strawberries, cranberries, prunes, concord grapes,
blackberries. These dark colored red/blue/purple foods are very rich
in powerful antioxidants called anthocyanins that protect again heart
disease by improving circulation and preventing blood clots. They have
many anti-aging phytochemicals that keep the blood circulating reducing
the effects of the Standard American Diet rich in trans fats and processed
foods.
When you make a salad make sure you have a variety of
different colors. Strive to get at least 5 colors on your plate. Use
fruits to balance the rest of the colors needed. This way you will get
closer to the 8 to 13 servings of fruits and vegetables required, and you
will get the variety of nutrients you need daily.
