Already a nutritional superstar for its antioxidant and anti-inflammatory benefits, garlic may also fight degenerative brain diseases like Alzheimer’s and Parkinson’s.
When environmental stress damages the brain, immune cells race to the site and multiply to protect the brain from further harm. Unfortunately, as these immune cells mobilize, they produce nitric oxide, a molecule that can benefit some tissues by opening up blood vessels for better flow to muscles but harm others, as excess nitric oxide is thought to contribute to degenerative brain diseases.
Now Missouri School of Medicine scientists have found that a carbohydrate in aged garlic, known as FruArg, can inhibit nitric oxide production and protect the brain against aging and disease.
Can you just order linguine with garlic and oil to reap the benefits? Not exactly. “Garlic supplements offer more beneficial properties,” says lead study author Zezong Gu, M.D., Ph.D., who recommends 300–1,000 mg a day of aged garlic extract powder to get the effects.
