Everyone knows by now that fast food, too much meat and too much fat are unhealthy. However, an unhealthy diet is not only bad for the heart and circulation, but also for the mind.

A diet with too many saturated fatty acids impairs brain performance. According to studies, after years of excessive consumption of saturated fatty acids, people show significant mental decline from the age of 60 compared to those who live less unhealthily. The more saturated fatty acids are consumed, the slower cognitive ability becomes in retirement.

Red meat is one of the foods that contains a lot of saturated fatty acids and is eaten far too often.
