Rat Study: High Carb Diet Induces Hepatic Steatosis and Increases Heart Fat by 43%

For a large part of the 1980s and 1990s fats have been considered the "source of all evil". Now, it is our carbohydrate consumption which is held to be responsible for diabetes, obesity and the other ugly faces of "the metabolic syndrom". A recent study by a group of scientists from Sao Paulo (Haubert. 2010) seems to confirm this "revised" hypothesis.

Over a period of 21 days, the scientists fed a group of rats (experimental) a 70% carbohydrate diet with astonishing or rather shocking results (cf. table 1)

 

Within three weeks the rats developed a fatty liver and their heart fat mass increased by 43%. While the scientists did not provide much information about the overall underlying mechanism of these changes, they emphasize the pronounced decline in tissue vitamin E produced by the high carb consumption. In how far additional vitamin E may have prevented some of the fat accumulation yet remains unknown and would warrant further investigation.
