A Study of the Effects of Fish Protein Intake on Glucose Regulation in Overweight and Obese Adults.

A 8 wk Study to Compare the Effects of Proteins Various Fish Species (Salmon, Herring, Cod) and Milk on Glucose Regulation in Overweight and Obese Adults.

The purpose of this study is to compare the possible health benefits of intake of proteins from salmon, herring, cod and milk on glucose tolerance in overweight and obese adults. Overweight and obese subjects often have reduced glucose tolerance, and previous findings from a study on cod proteins suggested that glucose tolerance was improved.

Participants receive 2.5g protein per day for 8 weeks as tablets.
