(17-05-07) Eating Fish May Actually Cause Diabetes

Evidence suggests that pollutants found in oily fish may be a cause of type 2 diabetes.
Korean researchers have found evidence that people who consume fish containing high levels of persistent organic pesticides (POPs) are more prone to developing insulin resistance, a precursor to diabetes. POPs are synthetic chemicals that accumulate in the fatty tissue of animals.
Many POPs have been banned in developed countries, but they remain in the food chain. Oily fish are prone to accumulating these fat-soluble chemicals.
This may be one reason the obese are more prone to diabetes -- more fat in the body can result in higher levels of POPs. Obese patients with low POP levels have a lower incidence of diabetes than those with higher levels.
