Because staple food is the main source of carbohydrate intake, especially starch, grains such as rice, wheat and corn with starch as the main component, and tuber foods such as potatoes and sweet potatoes are regarded as staple foods by people in different regions. Generally speaking, the staple food contains carbohydrates.

Long-term lack of staple food may cause amnesia;

A recent medical study in the United States pointed out that if women don't eat carbohydrate food, it may also lead to amnesia.

A survey by Tufts University in the United States found that women who don't eat high-energy foods such as pasta, bread, pizza and potatoes for a week will have memory and cognitive impairment.

Taylor, a psychology professor in charge of this research, pointed out that this is because brain cells need glucose as energy, but they can't store glucose, so they need continuous supply through blood. Insufficient carbohydrate intake may reduce the supply of glucose needed by brain cells, thus causing harm to learning, memory and thinking.
