Can people with stomach problems eat water chestnuts?
My family recently bought a lot of water caltrops (trapa), but my stomach has always been weak. My doctor has also advised me to pay attention to my daily diet, so I'm a bit worried that eating water caltrops might cause discomfort. May I ask, is it okay for someone with a sensitive stomach to eat water caltrops?

Water chestnuts are a nutritious food, rich in protein, minerals, and unsaturated fatty acids, offering certain health benefits. People with sensitive stomachs can generally consume water chestnuts, but should do so in moderation.
From the perspective of traditional Chinese medicine, water chestnuts have the effect of strengthening the spleen and boosting vital energy, which helps improve the function of the spleen and stomach. Therefore, for individuals with stomach discomfort, moderate consumption of water chestnuts is acceptable and can help replenish nutrition and enhance physical immunity. Additionally, water chestnuts contain substantial dietary fiber, and moderate intake can help stimulate intestinal motility and improve constipation. However, water chestnuts are considered a cold-natured food and are not easily digested. Excessive consumption by individuals with stomach issues may irritate the gastrointestinal mucosa, increase the digestive burden, and lead to discomforts such as abdominal pain and diarrhea. Hence, intake of water chestnuts should be controlled.
Prior to consumption, water chestnuts should be thoroughly cooked to soften their texture and improve digestibility. In daily life, individuals with stomach problems should also avoid spicy, greasy, raw, or cold foods, as these can irritate the gastric mucosa and cause damage.
