Eat less added sugar
Consuming excessive amounts of added sugar has been related to a number of chronic illnesses and health problems, including cognitive deterioration. The World Health Organization recommends less than 5% of calories from added sugar for optimal health.
A diet high in sugar has been linked to lower brain volume and memory problems, especially in the part of the brain that maintains short-term memory, according to research. For example, one research involving over 4,000 participants discovered that those who consumed more sweet beverages like soda had, on average, smaller overall brain volumes and worse memory than those who consumed less sugar. Reducing your sugar intake benefits both your memory and overall health.
