Garlic - How to use it
To All
We all hear about Garlic and how it is good for your health. Here is a report that may be interesting.
Garlic preparation affects anti-cancer effect Garlic can have an antitumor effect - but how the lily-related herb is prepared is important to retaining this health benefit, say U.S. researchers. Penn State researchers report that studies conducted in rats show that heating garlic just after crushing it causes it to lose its ability to retard a cancer-causing agent. But allowing the crushed garlic to stand for 10 minutes prior to heating enables garlic to maintain its anticancer effects.
The researchers tested garlic's ability to block the breast tumor-inducing chemical dimethylbenz(a)anthrancene (DMBA) from binding to rat breast cells. Dr. John A. Milner of Pennsylvania State University in University Park and colleagues gave rats corn oil either with or without crushed garlic. Following 2 weeks of treatment, the investigators administered the carcinogen DMBA to the rats. The rats given crushed garlic that was allowed to stand for 10 minutes prior to heating for 1 minute by microwave oven or roasting for 45 minutes by convection oven showed a 41% and a 21% reduction in breast cell changes linked to cancer, respectively, compared with the rats who did not receive garlic. But Milner also reported that garlic similarly heated without a rest period after crushing showed no anticancer effects.
Resting crushed garlic at room temperature stimulates the enzyme allinase, which stimulates the formation of allyl sulfur compounds. These compounds provide garlic's protective effect against tumor development, Milner told Reuters Health. Milner presented his group's findings last week at a Newport Beach, California, conference on the nutritional benefits of garlic. In another presentation at the meeting, Dr. Yu-Yan Yeh and doctoral candidate Lijuan Liu, also of Penn State, identified the water- and lipid-soluble compounds in garlic that cause a decrease in cholesterol production in rat liver cells. The compounds are some of the same that conferred cancer protection in Milner's study.
In liver cells exposed to three of the water-soluble allyl sulfur compounds in garlic (S-allyl-, S-ethyl-, and S-propyl-cysteine), cholesterol production decreased by 40% to 60%, while the lipid-soluble compounds "completely blocked cholesterol synthesis by making the liver cells unfunctional," Yeh told Reuters Health.
Yeh said that S-allyl cysteine is the major component in garlic that causes its hypocholesterolemic effect.
