According to relevant data, the staple food consumption of modern people is decreasing, showing a trend of insufficient food intake. This is a sign of improved living standards, but it also hides potential dangers.
Nutrition experts state that in addition to providing energy, carbohydrates from grain foods are the main source of B vitamins. A change in the status of staple foods can easily lead to a deficiency in Vitamin B1. It is reported that the Vitamin B1 content in coarse grains is much higher than in refined rice and flour. In 100 grams of corn, the content is 0.34 mg, while in 100 grams of premium rice, it is only 0.08 mg.
Excessive intake of animal-based foods poses even more serious risks. Animal fat is very detrimental to cardiovascular health. When carbohydrates are insufficient, animal fats are incompletely metabolized, causing toxic waste—ketones—to accumulate in the blood. Ketones can cause nausea, fatigue, and impair brain health. In recent years, the incidence of such diseases has risen significantly, largely due to the shift away from grain-based diets and the surge in animal food consumption.
So, how should we eat? The principle proposed by experts is "diversified diet, with grains as the staple." Specifically, an adult's daily grain intake should be around 400 grams, with a minimum of no less than 300 grams. Foods such as rice, millet congee, mung bean congee, and steamed rice cakes should become common dietary choices.
