About

The investigators have previously shown the intact protein from cod filet improves glucose regulation and serum lipid profile in overweight adults. A large amount of trimmings from various fish species such as cod is thrown away or sold at very low prices for animal feed, and analyses of the amino acid composition reveals that this can be a good protein source for humans. Two fractions are normally isolated from intact fish meal, i.e. water soluble and non-water soluble proteins. In the present study the investigators will compare these fractions, by studying their effects on glucose regulation in overweight/obese adults.

Full description

Participants receive 6g per day of water soluble on non-water soluble cod protein as tablets for 8 weeks.
