In recent years, as people's living standards have improved, many have started to consider eating coarse grains fashionable, believing that the more they eat, the better it is for their health, little realizing that this is another misconception.
It is understood that due to simple processing, coarse grains preserve many nutrients not found in refined grains. However, because coarse grains contain more cellulose and phytic acid, consuming more than 50 grams of cellulose daily and eating them long-term can hinder protein supplementation, reduce fat utilization, and cause damage to the functions of organs such as bones, the heart, and blood, as well as lower the body's immune capacity, and even affect fertility. Furthermore, coarse grains like oats, buckwheat, and corn have high phytic acid content, which can hinder the absorption of calcium, iron, zinc, and phosphorus, affecting the metabolic balance of minerals in the intestines. Therefore, experts recommend increasing the intake of these minerals when consuming coarse grains.
