1. Trans Fats
The good news is that not all fats are bad for you. However, a particular kind of fat called trans fat does have a detrimental effect on the brain. Trans fats are found naturally in animal products including meat and dairy, but even these are not as problematic as the industrially produced trans fats that get pumped into all sorts of packaged foods.
Otherwise known as hydrogenated oil, people who eat a lot of trans fat in the form of margarine, store-bought baked goods, chips and crackers, frozen and canned meals, and creamy beverages are at a greater risk for Alzheimer’s and dementia. Studies have shown that high consumption of trans fats also leads to earlier cognitive decline, lower brain volume, and poorer memory.
