Eating Junk Food

Harvard research shows what we eat has an impact on our ability to remember and our likelihood of developing dementia as we age. Junk food or any foods loaded with saturated fat raise blood levels of unhealthy low-density lipoprotein (LDL) cholesterol. Other kinds of fats, such as trans fats, do the same thing to LDL. LDL cholesterol builds up in, and damages, arteries. Diets high in cholesterol and fat might speed up the formation of beta-amyloid plaques in the brain. These sticky protein clusters are blamed for much of the damage that occurs in the brains of people with Alzheimer's.
