New research says fish body oil supplements, can enlarge the amount of a certain hormone affiliated with lowering the risk of Type 2 diabetes and heart disease, according to UPI.com.
"While prior animal studies found fish oil increased circulating adiponectin, similar effects in humans was not established," said Harvard School of Public Health’s Jason Wu, the lead author, through a statement. "By reviewing evidence from existing randomized clinical trials, we found fish oil supplementation caused modest increases in adiponectin in the blood of humans."
Researchers analyzed the data collected from 14 random, placebo-controlled trials. The trials included 1,323 subjects—682 were given fish oil and 641 were given placebos which usually came in the form of olive or sunflower oils.
The fish oil subjects saw heightened levels of adiponectin to the tune of 0.37 microgram per milliliter.
According to Wu, the study’s results hint at a varied effect of fish oil on adiponectin throughout all the trials. The differences across the trials were pretty significant. Wu said this suggests the fish oil supplementation may have a greater effect in certain some populations and may not be as effective in others.
"Although higher levels of adiponectin in the bloodstream have been linked to lower risk of type 2 diabetes and coronary heart disease, whether fish oil influences glucose metabolism and development of type 2 diabetes remains unclear," he said. "However, results from our study suggested higher intake of fish oil might moderately increase blood level of adiponectin, and these results support potential benefits of fish oil consumption on glucose control and fat cell metabolism."
The study was a printed in the journal Clinical Endorcrinology & Metabolism.
