May strengthen your central nervous system

Tahini includes chemicals that may benefit brain function and lower your chance of acquiring neurodegenerative disorders such as dementia. Sesame seed components have been found in test-tube research to protect the human brain and nerve cells from free radical damage. Sesame seed antioxidants have the ability to penetrate the blood-brain barrier, which means they may leave your bloodstream and directly influence your brain and neurological system. According to one animal study, sesame antioxidants may also help reduce the production of beta-amyloid plaques in the brain, which is a hallmark of Alzheimer's disease.

Furthermore, a rat study discovered that sesame seed antioxidants reduce the negative effects of aluminum poisoning in the brain. This is preliminary research on isolated sesame seed antioxidants, not on whole sesame seeds or tahini. The more human study is required before conclusions may be drawn.
