Whether you eat breakfast or not, your intestines are absorbing water and other nutrients from your feces every minute of every day. There are thousands or hundreds of millions of microorganisms in the human gut that break down food, and the gut is absorbing these substances. It is often said that it makes sense to eat a good breakfast, a full lunch and a small dinner. It has been shown that eating breakfast helps the bowel movement and makes one feel like having a bowel movement. It facilitates the discharge of human waste and does not cause toxins to accumulate in the body, which is harmful to the human body. And eating the meal is conducive to the health of the stomach, many people have diseases in the stomach are caused by irregular diet. Eating breakfast also reduces the risk of gallstones in the human body. But the intestines will not absorb those impurities, only some water, inorganic salts, vitamins, etc., so do not worry too much.
