A diet containing compounds found in green tea and carrots reversed Alzheimer's-like symptoms in mice genetically programmed to develop the disease. The two compounds were EGCG (epigallocatechin-3-gallate), a key ingredient in green tea, and FA (ferulic acid), which is found in carrots, tomatoes, rice, wheat and oats.
After three months, the treatment completely restored working memory deficits seen in the Alzheimer's mice. The compounds appeared to help prevent amyloid precursor proteins from breaking up into amyloid beta, as well as reduce neuroinflammation and oxidative stress in the brain.
The amount of EGCG and FA was no more than could be gained from an appropriate diet.
