News Briefs: There’s little evidence of garlic’s health benefits
While a necklace of garlic may ward off vampires, a report issued by the Agency for Healthcare Research and Quality (AHRQ) in Rockville, MD, says studies that show reduced low-density lipids (LDL) after regular dietary use of garlic do not demonstrate a long-term effect.
Researchers reviewed and analyzed scientific evidence related to clinical studies of garlic in humans to determine the effectiveness of garlic in controlling cholesterol.
While garlic may reduce LDLs in the first three months of use, the long-term effects have not been proven, according to the report.
In fact, after six months of use, there were no further reductions in LDL or triglycerides, and there was no effect on high-density lipid levels.
