Fish Oil Supplements may Help Cut Diabetes Risk

Fish oil supplements increase the amount of a hormone that is associated with a reduced risk of diabetes and cardiovascular disease.

Fish oil supplements, also called omega 3 fatty acid capsules, raise levels of adiponectin in the bloodstream. Adiponectin is an important hormone that has beneficial effects on metabolic processes like glucose regulation and the modulation of inflammation. In long-term human studies, higher levels of adiponectin are associated with lower risks of type 2 diabetes and coronary heart disease.

Advantages of Eating Fish Foods - Health Benefits
Researchers worldwide have discovered that eating fish regularly is good for health. Regular consumption of fish may reduce the risk of diseases such as asthma, prostate cancer and eyesight.

"While prior animal studies found fish oil increased circulating adiponectin, whether similar effects apply in humans is not established," said the study's lead author, Jason Wu, PhD, of the Harvard School of Public Health.

"By reviewing evidence from existing randomized clinical trials, we found that fish oil supplementation caused modest increases in adiponectin in the blood of humans," Wu stated.

The meta-analysis reviewed and analyzed results from 14 randomized, placebo-controlled clinical trials. In total, 682 subjects were treated with fish oil, and 641 were given placebos - most commonly olive and sunflower oils. In those taking fish oil, adiponectin levels increased by 0.37 ug/mL.

Fish: The Best and The Worst
Some fish are contaminated with high levels of methyl mercury. Methyl mercury is a neurotoxin, which affects the pregnant or lactating mother’s child’s brain.

The results also suggested the effect of fish oil on adiponectin differed substantially across the trials, suggesting that fish oil supplementation may have stronger influence on adiponectin in some populations and weaker effects in others.

This is the first study to pool data from previous trials to suggest that fish oil consumption increases adiponectin in humans. The findings quantify the potential impact of fish oil on adiponectin level, and highlight the need to further investigate populations that may particularly benefit from fish oil supplementation.

An Active Heart
The heart pumps blood constantly providing the power to sustain life.

"Although higher levels of adiponectin in the bloodstream have been linked to lower risk of diabetes and coronary heart disease, whether fish oil influences glucose metabolism and development of type 2 diabetes remains unclear," said Wu.

"However, results from our study suggest that higher intake of fish oil may moderately increase blood level of adiponectin, and these results support potential benefits of fish oil consumption on glucose control and fat cell metabolism," the researcher added.
