High Blood Levels of Industrial Trans Fat Linked With Increased Risk of Dementia
Industrial trans fats are created when vegetable oils are chemically altered to stay solid at room temperature. They are found in coffee creamer, cakes, pie crusts, frozen pizza, cookies, crackers, biscuits and dozens of other processed foods. A recent study has found a link between high serum levels of industrial trans fats and an increased risk of developing dementia.
Participants in the study included 1,628 people aged 60 years or older. None of them had dementia at the beginning of the study. A blood test was administered at the start of the study to measure serum levels of elaidic acid, a biomarker for industrial trans fats. Participants were followed for 10 years and all cases of dementia were recorded.
During the follow-up period, 377 participants developed dementia. After adjusting for high blood pressure, diabetes, and smoking, the researchers found that participants with the two highest levels of trans fats were 52% and 74% more likely to develop dementia compared to those with the lowest levels.
The study was conducted by researchers from Kyushu University. It was published online ahead of print on October 23, 2019 in the journal Neurology.
