Cabbage compound protects healthy tissue from radiation damage

Posted by Neill Abayon


A team of US researchers has discovered that an anti-cancer compound present in cruciferous vegetables, such as cabbage, cauliflower and broccoli, also protects rodents from lethal doses of radiation.  

 The compound, called 3,3'-diindolylmethane, and known more simply as "DIM," is already shown to be safe in humans, and so the researchers expect it could serve as a shield to protect healthy tissue in human cancer patients from damage by radiation therapy, or lessen its side effects.

The team, from Georgetown University Medical Center (GUMC) in Washington, DC, reports its findings in the latest online issue of the Proceedings of the National Academy of Sciences (PNAS).

One of the researchers, Eliot Rosen, a professor of oncology, biochemistry and cell and molecular biology, and radiation medicine at Georgetown Lombardi Comprehensive Cancer Center, a part of GUMC, says:

"DIM has been studied as a cancer prevention agent for years, but this is the first indication that DIM can also act as a radiation protector."

Strawberries: Sweet and Tasty Treat with Anti-Aging Power

Posted by Neill Abayon

There is strong evidence that strawberries are a heart-protective fruit, an anti-cancer fruit, and an anti-inflammatory fruit all rolled into one.

Cancer Prevention

There have been many published reports on the anticancer effects of strawberries. Strawberries are one of the few sources, along with raspberries and grapes, of ellagic acid, a compound which has been shown to prevent carcinogens from turning healthy cells into cancerous ones. Strawberries also contain a multitude of cancer-fighting compounds, including vitamin C, folate, anthocyanins, quercetin and kaempferol.

Cardiovascular Disease Protection

New research has found that strawberries may offer cardiovascular disease protection. The study found that those who reported eating the most strawberries experienced lower blood levels of C-reactive protein, a blood biomarker that signals the presence of inflammation in the body.

Anti-clotting Effect

Strawberry consumption may protect against blood clot formation. An animal study found strawberries had a powerful anti-clotting effect.

Cancer boost from whole carrots

Posted by Neill Abayon

The anti-cancer properties of carrots are more potent if the vegetable is not cut up before cooking, research shows.

Scientists found "boiled before cut" carrots contained 25% more of the anti-cancer compound falcarinol than those chopped up first.

Experiments on rats fed falcarinol have shown they develop fewer tumours.

The Newcastle University study will be presented at NutrEvent, a conference on nutrition and health, to be held in France.

Lead researcher Dr Kirsten Brandt, from Newcastle University's School of Agriculture, Food and Rural Development, said: "Chopping up your carrots increases the surface area so more of the nutrients leach out into the water while they are cooked.

"By keeping them whole and chopping them up afterwards you are locking in nutrients and the taste, so the carrot is better for you all round."

The Newcastle scientist, along with colleagues at the University of Denmark, discovered the health benefits of falcarinol in carrots four years ago.
