A recent study shows that the staple food consumption of modern urban dwellers is decreasing, reaching a point of insufficiency. This is a sign of improved living standards, but it also hides potential dangers.
Staple foods are rich in B vitamins According to nutrition experts, carbohydrates in grain foods not only provide energy for the body but are also the main source of B vitamins. A change in the status of staple foods can lead to a significant risk: vitamin B1 deficiency. It is reported that the vitamin B1 content in coarse grains is much higher than in refined rice and flour. 100 grams of corn contains 0.34 mg of vitamin B1, while 100 grams of premium rice contains only 0.08 mg. Animal foods replacing staple foods can easily lead to toxin accumulation Excessive intake of animal foods poses even more serious risks. Animal fat is very detrimental to cardiovascular health. When carbohydrates are insufficient, animal fat is metabolized incompletely, causing toxic byproducts called ketones to accumulate in the blood. Ketones can cause nausea, fatigue, and damage to brain health. In recent years, the incidence of such diseases has risen significantly, which is largely related to a shift away from a grain-based diet and a surge in the consumption of animal foods. Adults should consume no less than 300 grams of staple food daily Experts recommend "a diverse diet with grains as the staple." Specifically, an adult's daily grain intake should be around 400 grams, with a minimum of 300 grams. White congee and rice noodles should be regular parts of the diet. The daily calorie requirement for the human body is determined by its needs and must be met. The sources of calories are protein, carbohydrates, and fat. Staple foods are the main source of carbohydrates. If you don't eat staple foods, calories will be derived from protein and fat instead. This can lead to a deficiency of protein in the body, and over time, result in malnutrition. Therefore, even during weight loss, one should not completely eliminate staple foods.
