Eating trans fats has been linked to a startling high increase in the risk of developing Alzheimer’s disease, underscoring the importance of eliminating this ingredient from food products. The study comes from Kyushu University Hospital Fukuoka, where researchers tracked more than 1,600 older adults for a decade, finding that trans fats consumption was ‘significantly associated’ with developing dementia.
Trans fats is the term used to refer to artificial trans-unsaturated fatty acids (aka, partially hydrogenated oils), an ingredient that used to be considered generally safe for use in food. As a result of that designation, many food products — particularly fast food, junk food, and prepackaged foods — sold in the US contained trans fats as an ingredient.
