Dr. Ruderman: Dementia risk higher in those who eat more trans fats

(KUSI) – Good Morning San Diego medical expert, Dr. Steven Ruderman, discussed a new study that said of older adults in a Japanese town has found that those whose blood contained higher levels of trans fats were more likely to develop dementia than those with lower levels.

Sweet pastry can be a rich source of trans fats, which may raise the risk of dementia in some people, according to new research.

The researchers also found that sweet pastries were likely the biggest source of dietary trans fats in that population.

There are two primary sources of trans fats in the human diet: natural and artificial. Natural trans fats are present in small amounts in dairy products and the meat of some animals.

Artificial trans fats, or trans fatty acids, are the primary source of trans fats in the diet and are the product of an industrial process that adds hydrogen to vegetable oil to make it solid.

According to the American Heart Association, consumption of trans fats can raise the risk of heart disease, stroke, and has links to a higher risk of type 2 diabetes.

In a recent Neurology paper, the new study authors describe how they linked trans fats to a higher risk of dementia using data from an ongoing health study of people living in the town of Hisayama in Japan.

“These results,” says senior study author Toshiharu Ninomiya, “give us even more reason to avoid trans fats.” He adds that “In the United States, the small amounts still allowed in foods can really add up if people eat multiple servings of these foods, and trans fats are still allowed in many other countries.”
