Eating vegetables and fruits regularly can not only supplement folic acid to prevent cancer, but also increase gastrointestinal peristalsis through fiber, shorten stool retention time and relieve constipation. These small gastrointestinal health care have long been considered to be related to the prevention of colorectal cancer. Many modern people usually can't get enough fiber every day because of their lifestyle, although this is not necessarily related to colorectal cancer. However, in the long run, the burden on the stomach and intestines becomes heavier and heavier, and various chronic diseases impact the body. Whether enough dietary fiber can be supplemented has become an important health care topic. In addition to supplementing at least 30 grams of dietary fiber every day, it is best to drink more boiled water to help the fiber pass through the body. By the way, the old toxins accumulated in the body are discharged together with metabolic waste and fiber. You will find that the first benefit of supplementing enough dietary fiber is slimming and environmental protection in the body. The simplest fiber sources are vegetables, fruits and drupes. Nowadays, many people drink "Jinglitang" and "high fiber meal replacement", which is also a convenient choice for modern busy office workers.
