Fish oil may help fight diabetes
Omega-3 fatty acids – commonly referred to as fish oil supplements – have been proven to have a variety of health benefits, many associated with heart health. Now, research from the Harvard School of Public Health has found that omega-3s may also be associated with a lower risk of type 2 diabetes. The supplements raise the levels of the hormone adiponectin in the blood, which is associated with fighting off both diabetes and heart disease.
The study analyzed the data from 14 existing clinical trials, involving 682 participants treated with fish oil and 641 who were given placebos. In the participants taking the supplements, adiponectin levels increased, though this rise varied across different populations. The results also indicate that fish oil consumption may have a positive effect on glucose control and fat cell metabolism, according to the researchers.
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 determine which populations may benefit the most from fish oil.
