The Connection Between Diet and Memory Loss

Growing data supports the connection between diet and memory loss. Just like some foods have brain boosting qualities, some also negatively affect them. We’re taking a deeper look into this connection and giving you the top foods to eat, including ones to avoid.

Diet and Memory Loss

A healthy brain relies on a steady flow of blood, oxygen, and other nutrients at all times. Anything that interferes with that process compromises thinking and memory, along with other more severe consequences. Vital nutrients are transported through blood vessels. Damage to these vessels or a blockage caused by cholesterol buildup can deprive the brain of oxygen-rich blood to function normally.

Diets high in saturated and trans fats are the number one cause of unhealthy cholesterol levels and buildup in blood vessels. In a recent study, a group of individuals who ate a high saturated fat diet performed worse on memory and thinking tests than a group that consumed the lowest levels of saturated fat. In addition, a gene variation associated with cholesterol levels is being studied that shows a greater risk of developing Alzheimer’s for individuals with this gene variation.
