Introduction
Under normal circumstances, red bean and coix seed water can help regulate the gastrointestinal tract to some extent. However, its effect in regulating the gastrointestinal system is limited and cannot replace standardized treatments for gastrointestinal diseases. Coix seed has a relatively cooling property, and excessive consumption by individuals with gastrointestinal deficiency-cold may cause abdominal pain and diarrhea; therefore, intake should be controlled. Gastrointestinal regulation also requires combining with regular dietary habits and avoiding spicy and irritating foods.

In general, red bean and coix seed water can help regulate the gastrointestinal tract to some extent. The detailed explanation is as follows:

Red beans have a soft texture, and their protein content becomes easier to digest and absorb after cooking, causing minimal irritation to the gastrointestinal mucosa. Additionally, the dietary fiber in red beans promotes intestinal peristalsis and helps maintain normal digestive rhythms. Coix seed contains various amino acids and B vitamins, which aid in the repair and renewal of gastrointestinal mucosa, enhancing the mucosal barrier function. Furthermore, the diuretic effect of coix seed can regulate water balance in the intestines, alleviating gastrointestinal discomfort caused by dampness retention, such as bloating and poor appetite. Together, these two ingredients work synergistically to promote digestion and protect the mucosa, assisting in the regulation of gastrointestinal function.

The effect of red bean and coix seed water in regulating the gastrointestinal tract is limited and cannot replace standard treatments for gastrointestinal diseases. Coix seed has a relatively cold nature, and excessive consumption by individuals with gastrointestinal deficiency-cold may cause abdominal pain and diarrhea; therefore, intake should be controlled. Gastrointestinal regulation should also involve maintaining regular eating habits and avoiding spicy or irritating foods. Relying solely on beverages is not advisable. If gastrointestinal discomfort persists, timely medical consultation is necessary to determine the underlying cause.
