fish_T2DEating fish is good for you, right? This may not be entirely true, according to a new study. Diabetes Care published a study that suggests people who had higher exposure to mercury earlier in life have a greater risk of developing diabetes later in life.

Fish lovers ultra-healthy meals may be shadowed with the possibility of causing beta-cell dysfunction. A study including more than 3,800 young American adults, aged 20-32 years, free of diabetes in 1987, were followed until 2005.

At the start of the study, their mercury baseline levels were taken. Each participant had their glucose levels assessed, oral glucose tolerance tested, and HbA1c  measured.

In the course of 18 years, about 7% of participants developed diabetes. Bearing in mind lifestyle factors, mercury levels were positively associated with the incidence of diabetes. People who had higher mercury levels at the start of the study were more likely to develop diabetes.

Nobody is saying avoid fish. However, there are some fish that are better choices than others. Examples of low mercy fish are tilapia, salmon, and flounder. You may want to limit the consumption of swordfish, shark, and tuna.
