Researchers from the UK part of the EPIC – Norfolk study with 21,984 participants aged 40-79 years followed for more than 10 years. Have found that higher fish intake was associated with significantly lower risk of diabetes.
Unfortunately folks who consumed one or more portions of shellfish per week had an increased risk of diabetes, so its best to eat these in moderation. Although the researchers state that this result requires further investigation.
In regard to fish the effect was no longer significant when obesity was factored in. Interestingly though when folks are trying to loss weight they loss more with a healthy diet containing fish.
The study reinforces the advice to eat fish regularly as part of a healthy diet.
