Citric Fruits - A Healthy Food

Citrus, or citric, fruits, have been shown to not only assist in weight
loss, but also reduce the risk of some cancers.

Grapefruit in particular seems to have very beneficial qualities. It has
been widely accepted for many years that grapefruit may assist in
reducing weight. What's not so widely known is that it may also
assist in preventing some cancers.

Oranges, tangerines and grapefruit can all contribute to lowering
cholesterol, which in turn is often related to weight loss, and is always
related to a healthy lifestyle.

So the message is eat lots of oranges, tangerines and grapefruit, and
they'll contribute to your healthy lifestyle.

New studies suggested once again that citric fruits including
oranges, tangerines, and grapefruits help fight cancer, high
cholesterol, and obesity.

Studies both at Texas A&M University and Kanazawa Medical
University in Japan showed that compounds in citric fruits can
help reduce the risk of colon cancer. Researchers at Texas A&M
University found that freeze-dried grapefruit, similar to the
whole grapefruit, can reduce the incidence of early colon cancer
lesions in animals. The Japanese researchers found anti-colon
cancer properties in nobiletin - a compound found in tangerines.

Grapefruit can also reduce the risk of cancer caused by smoking.
A study on the cancer prevention was done by the researchers at
the University of Hawaii. The researchers found that drinking 6
ounces of grapefruit juice a day reduces the activity of a liver
enzyme that is thought to activate toxic chemicals in the smoke.

On another front, scientists from the USDA and a Canadian
company isolated a compound - polymethoxylated flavones (PMFs) -
from orange and tangerine peels that can actually lower
cholesterol in animals. They found that use of food containing
1% PMFs can lower cholesterol by 32 to 40%.

Grapefruits also promote weight loss. Researchers at Scripps
Clinic in San Diego found that grapefruit may trigger weight
loss by lowering insulin levels, an excess of which is linked to
weight gain. Effect of grapefruits on weight loss was confirmed
in humans. An early study by the same researchers confirmed that
eating grapefruit or drinking juice with meal can help the obese
lose weight.

Even the interaction of grapefruit juice with drugs, a bad trait
for grapefruit, has been explored. Researchers at Texas A&M
Citrus Center studied the interaction between grapefruit
compounds and drugs in hopes that this interaction can be taken
advantage of to increase bioavailability of drugs in humans.

These studies were presented in the American Chemical Society
Annual Meeting being held in Pennsylvania during Aug. 22 through
