Whole grains are part of carbohydrates. Let’s learn about whole grains.
When eating whole grains, it is best to mix and match them with fine grains, which can achieve the effect of complementing each other's strengths. Moreover, eating together with vegetables, meat, eggs, milk, fruits, etc. is more in line with the principle of nutritional balance.
People with stomach problems and poor digestion should eat less whole grains, because the crude fiber in whole grains staying in the stomach for too long will stimulate the secretion of gastric juice, leading to abdominal distension and discomfort to the human body. Nuts, beans, glutinous rice, etc. are not suitable for eating too much.
Some legumes, such as soybeans and lentils, cannot be eaten raw and must be cooked. Because it contains protease inhibitors, it will affect protein digestion and absorption; it contains saponin, phytohemagglutinin, etc., which can cause vomiting and abdominal pain. Also, do not add salt when cooking beans, otherwise it will destroy the water-soluble vitamins B1 and B2 in them.
