Consumption of fish wards off kidney damage in diabetics

According to a recent stud eating at least two servings of fish each week wards of decline of kidneys in diabetics. The study was conducted on more than 22,000 adults in England.

Previous studies have also revealed that fish and fish oil consumption decrease protein in the urine, increase glucose tolerance, decrease fats in the blood, and lower blood pressure. All these are beneficial for diabetics.

The researchers conducted urine tests. The participants were also asked to answer dietary-lifestyle questionnaire. This led to the conclusion that diabetics who on average ate less than one serving of fish each week were four times likely to have macroalbuminuria (abnormally high levels of protein in the urine) than those who ate fish regularly.

The study also took into account lifestyle factors, use of alcohol and tobacco , family medical history, socio-economic status, and ethnicity. But it was found these didn't have a significant impact on risk of macroalbuminuria.
