Trans fats have been shown to increase bad cholesterol (LDL) and
decrease good cholesterol (HDL). Now, new research suggests that trans
fats may also affect memory. Researchers found that among men under 45,
those who ate the most trans fats performed 10% worse on a word recall
test than those who ate the least. Scientists think the oxidizing effects of
trans fats may cause brain cells involved in memory to die off.
However, effects could be reversed by eating healthy and reducing trans
fats. The study only shows an association between high consumption of
trans fats and memory impairment.
