Diets that are high in protein and cereal grains produce an excess of acid in the body which may increase calcium excretion and weaken bones, according to a new study.

The study found that increasing the alkali content of the diet, with a pill or through a diet rich in fruits and vegetables has the opposite effect and strengthens skeletal health.

Scientists have expressed genes from snapdragon in tomatoes to grow purple tomatoes high in health-protecting anthocyanins.

Anthocyanins are naturally occurring pigments found at particularly high levels in berries such as blackberry, cranberry and chokeberry.

Scientists are investigating ways to increase the levels of health-promoting compounds in more commonly eaten fruits and vegetables.

Scientists from the UK's Institute of Food Research have found a new possible explanation for why people who eat more fruit and vegetables may gain protection against the spread of cancers.

They have shown that a fragment released from pectin, found in all fruits and vegetables, binds to and is believed to inhibit galectin 3, a protein that plays a role in all stages of cancer progression.

Mice given quercetin, a naturally occurring substance found in fruits and vegetables, were less likely to contract the flu.

The study also found that stressful exercise increased the susceptibility of mice to the flu, but quercetin canceled out that negative effect.

Quercetin, a close chemical relative of resveratrol, is present in a variety of fruits and vegetables, including red onions, grapes, blueberries, tea, broccoli and red wine.

(Texas A&M University - Agricultural Communications) Well beyond the advice to drink enough H2O and not eat too much NaCl, the nation's chemists will get elemental with grapefruit, onions, peppers, tomatoes, carrots and watermelons this week at the American Chemical Society meeting.The world's largest scientific society is observing the 100th anniversary of its agricultural and food chemistry division with a series of talks aimed at new discoveries in the health benefits from phytochemicals in fruits and vegetables.

Fruits and vegetables contain essential vitamins, minerals and fiber that are key to good health. Now, new research suggests plant foods also may help preserve muscle mass in older men and women.

Tobacco smokers who eat three servings of fruits and vegetables per day and drink green or black tea may be protecting themselves from lung cancer, according to a first-of-its-kind study by cancer researchers.

The study is the first to find that plant components called flavonoids may prevent the disease.
