The participants were divided into 2 groups. The first group did not eat fish. The second group was fed 200 grams of sardines per week. They were advised to eat bones as well, which are rich in vitamin D and calcium.

After a year, the scientists re-examined the health of the two groups. The results showed that the number of people at high risk of diabetes in the group that did not eat sardines decreased by 5%. Meanwhile, the number of people at high risk of diabetes in the group that ate sardines decreased by 29%.

Those who ate sardines also reported that in addition to a significant reduction in diabetes risk, they also noticed a marked improvement in health. Indicators such as triglycerides, blood pressure, and insulin resistance also decreased. At the same time, their bodies also increased levels of good cholesterol and adiponectin, a hormone that helps break down glucose.
