Omega-3s Boost Protein Synthesis

Omega-3s Boost Protein Synthesis Cold water fish is a great source of essential fatty acids known as omega-3s, which include eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). These unsaturated fats are considered essential since they can only be taken in through diet and are responsible for numerous important functions by your body. A study recently published in the American Journal of Clinical Nutrition suggests that omega-3s might even be able to stimulate protein synthesis in seniors.

Nearly half of Americans aged 65 and older are believed to suffer from some degree of sarcopenia, a condition linked to loss of muscle size and strength. Researchers had 16 otherwise healthy seniors supplement with 4 grams of omega-3 fatty acids (1.86 grams of EPA and 1.5 grams of DHA) for 8 weeks. A control group got corn oil. Although scientists aren't sure exactly why, the seniors who took omega-3s realized an increased rate of protein synthesis along with a greater supply of amino acids.

True Strength Moment: Scientists think that the omega-3 fatty acids increased activation of an mTOR signaling pathway responsible for muscle cell growth. Whether these essential fatty acids have a similar effect on younger subjects hasn't been established, but the value of 'good' fats should not be underestimated.
