More dangerous Soybean oil for obesity that coconut oil


A study by the University of California researchers in Riverside (United States), published in the journal Plos One, has highlighted a rich soybean oil diet had some effect on weight gain and the occurrence of type 2 diabetes.

The obesity epidemic in the United States pushes researchers to do further studies to determine the precise causes of this serious public health problem. Fat, obviously, but also fructose are well in line of sight specialists. For example, the United States, soybean oil consumption has increased dramatically over the past four years.

It is found in processed foods, margarines, salad dressings and snack foods. It now represents 60% of the consumed edible oil. Hence the urgent need for specialists to establish its relationship with weight gain and the occurrence of diabetes.

A team from the University of California researchers in Riverside (USA), directed by Poonamjot Deol, Frances M. Sladek assistant professor of biology and neuroscience, tried to determine which of these three nutrients – fructose, the coconut oil and soybean oil – was the most dangerous for obesity and the risk of developing type 2 diabetes.

The researchers worked with 4 groups of mice. Each group was fed a different diet. The first received a diet rich in coconut oil at 40%, the equivalent of fat consumed by Americans. In the second group, approximately half of the coconut oil was replaced with soybean oil.

The latter two diets were rich in fructose always in proportion equivalent to what the average American consumes. All diets contained the same number of calories.

The results of the study , published in the journal “Plos One”, have shown that mice on the soybean oil based diet (group 1) had a weight gain of 25% compared to those who had followed the diet based on coconut oil and 9% for both groups “enriched fructose”. These two groups “enriched fructose” recorded their side up 12% weight compared to the group who had followed the diet based on coconut oil.

Also in mice of the group “soybean oil”, the researchers found damage in the liver, a higher rate of diabetes and insulin resistance that had no mice in group 2.

Finally, the results have shown that fructose was less severe metabolic effects as soybean oil, but it posed a risk to the kidneys.
