FISH OIL PREVENTS MUSCLE WASTING

Fish and fish oils are rich in a type of fat called omega-3 or n-3 fatty acids. These fatty acids have been shown to lower blood triglycerides, increase insulin sensitivity, and reduce risk of heart disease and stroke. Continuing research involves the role of omega-3 fatty acids on the immune system, rheumatoid arthritis, asthma, kidney disease, cancer, and depression. These fats may also regulate muscle growth. In this study, rats were given different diets, one of which was rich in n-3 (omega 3) fatty acids for 3 weeks. During this time the rats had their hindlimbs suspended so they were not used, which resulted in significant muscle atrophy or muscle wasting. The rats supplementing with n-3 fatty acids had the least muscle and bone loss. Thus, n-3 fatty acids may help during periods of muscle disuse (such as breaks in training) by slowing the loss in both muscle and bone.
