Protect Your Heart With Fresh Garlic
Getty ImagesI think its safe to say that youll never need to use garlic to repel an old-school vampire. Plus, 21st-century vamps are so cute that Im not sure Id want to repel any of them. (Im looking at you, True Blood Bill.)
But heres a new garlic discovery I hope you will make use of: Researchers have discovered why freshly crushed garlic protects your heart.
That garlic has health benefits is nothing new. Since at least 1500 BC, healers in China and India have used the odiferous bulb as a blood thinner. Hippocrates, the father of modern medicine, used it to treat cervical cancer. Louis Pasteur reported on garlics antibacterial and antifungal powers, which inspired Albert Schweitzer to use it against dysentery in Africa.
But now, a team of researchers from the Cardiovascular Research Center at the University of Connecticut School of Medicine have learned how freshly crushed garlicÂas opposed to dried or cooked garlicÂprotects the heart.
Why is fresh garlic better?
âFreshly crushed garlic generates hydrogen sulfide, a gas that is also generated from rotten egg,â says study coauthor Dipak K. Das, PhD, ScD, a professor and director at the Cardiovascular Research Center. âAlthough this gas in excess may become poisonous, in small quantities it functions as an intracellular signaling compound and can protect the heart."
Because the hydrogen sulfide is a short-lived gas, it disappears when garlic is dried, processed, or cooked, he adds. Dried or processed garlic does retain its antioxidant effects, however, and helps protect against free radical damageÂbut not to the extent that fresh garlic does.
In the study, published in the August 12 issue of the Journal of Agricultural and Food Chemistry, the scientists gave freshly crushed garlic and dried garlic to two groups of lab rats, then studied how well the animals hearts recovered from simulated heart attacks. âBoth fresh and processed garlic reduced damage from lack of oxygen, but the fresh garlic had a significantly greater effect on restoring good blood flow in the aorta, and it increased pressure in the hearts left ventricle,â Das says.
Tips for using fresh garlic
The amount of garlic you need to get the heart-healthy benefits is about a clove a day. According to Herbal Therapy & Supplements, a handy guide by herbalists David Winston and Merrily A. Kuhn, RN, PhD, the best way to use garlic is to mince a clove, let it stand 10 to 15 minutes, then mix it with yogurt, applesauce, honey, or some other carrier agent. If you eat some parsley afterward, it will help control garlic breath.
