A study by Kaiser Permanente found that eating fish once a week reduced the risk of Multiple Sclerosis (MS) by 44%!
Fish are rich in omega-3 polyunsaturated fatty acids. The study found that eating fish, and also taking fish oil supplements, reduced the risk of MS in the 1,153 patients studied.
The researchers explained that MS is now recognized as a chronic inflammatory disease of the central nervous system. That inflammation leads to degenerative changes. The fatty acids found in fish are thought to decrease the inflammation, and thereby prevent the degeneration of the brain and nerves.
