Sea cucumber is not recommended for patients with gastric ulcer. Because sea cucumber contains a lot of vegetable protein, fat and cholesterol, which are difficult to be decomposed and absorbed by the human digestive tract, thus increasing the burden on the gastrointestinal tract and causing indigestion. For patients with gastric ulcer, they can choose the following types of food, such as Chinese yam, monkey head mushroom, kiwi, etc., in their daily diet. Because the above foods are rich in amino acids, vitamin C, mycelium and other components. Amino acids have a positive impact on promoting collagen synthesis in the body and speeding up the regeneration and healing of damaged cells. Vitamin C, as an antioxidant, can not only enhance the phagocytic activity of the body, but also eliminate free radicals in the body to prevent cancer. Mycelium, on the other hand, can inhibit the reproduction and growth of harmful bacteria in the body, playing an anti-inflammatory and antiseptic dietary effect.
