Since our digestive systems are not suited for eating meat, it is inevitable that meat-eaters complain about difficulty with excretion. Due to the drawback of having very little fiber, meat moves very slowly through the human digestive tract (four times slower than grains and vegetables), so in our society, constipation has become a common affliction.
Many modern research reports have shown that the fiber that promotes normal excretion can only be obtained from various vegetarian foods. In contrast to meat, vegetables, grains, and fruits retain more water and pass through the digestive tract more easily. Vegetables contain a large amount of fiber, and this substance is sufficient to prevent diseases. According to modern research, natural fiber can effectively prevent diseases such as appendicitis, colitis, heart disease, and obesity.
