To help your stomach accept coarse grains with less palatable textures, you need to pay attention to preparation methods, such as pairing them with refined grains, processing them finely, or making them into local specialty foods. When eating coarse grains, it's important to do so gradually to avoid intestinal reactions. They should also be paired with meat dishes, and you should drink plenty of water. For the average person, a daily intake of 30-60 grams of coarse grains is appropriate. However, the following groups should consume them with caution.
1. People with poor gastrointestinal function
The gastrointestinal function of the elderly and children is weaker, and too much dietary fiber is a significant burden on their stomachs and intestines. 2. People deficient in elements such as calcium and iron
Coarse grains contain phytic acid and dietary fiber, which combine to form precipitates that hinder the absorption of minerals and affect the metabolic balance of minerals in the intestines. 3. People with digestive system diseases
If you have liver cirrhosis with esophageal varices or a stomach ulcer, consuming large amounts of coarse grains can easily cause rupture and bleeding of the varices or ulcer bleeding. 4. People with low immunity
If the daily intake of cellulose exceeds 50 grams over a long period, it can impede protein replenishment, reduce the utilization of fats, and cause damage to the functions of organs such as bones, the heart, and blood, thereby lowering the body's immune capability.
