04. Margarine

Dietitians and health specialists point out that, in addition to being processed foods, margarine products are also high in trans fats, which can raise LDL (bad cholesterol) levels. Both margarine and butter are considered harmful to our brains when consumed in large amounts and frequently. Studies have shown that diets focused on increasing the intake of fresh fruits and vegetables can improve our cognitive health over the years, rather than incorporating high consumption of processed foods high in harmful substances.
