To consume the cod could contribute to warn the diabetes of type 2, according to the results of a test préliminaire1 led by three searchers in nutrition and a physician of the Laval university, to Quebec.
This crossed test has been led by ten men and nine women showing signs of resistance to the insulin, a metabolic disturbance that includes a big risk to drive to the diabetes of type 2.
The team of researchers wanted to know if the nature of the proteins consumed could have a specific effect on the sensitivity to the insulin. according to the results, the régime to basis of cod proteins would have reduced of 29% the resistance to the insulin, while the one to basis of animal proteins would have increased this resistance of 3%.
According to the authors of the survey, such an effect of the cod proteins on the sensitivity to the insulin could contribute to counter the metabolic process leading to the diabetes of type 2.
Two food different
The researchers have in fact compared the effects on the metabolism of the insulin of two food relatively weak in fat matters. Each included an energizing contribution coming from guides in a proportion of 51% to 52%, of lipids for close to 32%, and of about 18% to 19% of proteins.
The source of the proteins varied from a régime to the other: of the cod, a skinny fish who is not particularly rich in omega 3, for a group, and a mixture of beef, pork, veal and dairy products for the other.
Other tests demonstrated that the omega 3 of navy source had a similar effect on tolerance to the insulin. The results of the present test indicate that the very nature of the fish proteins would play a role in this regard, but regardless of their content in omega 3.
