(Garlic + Green Onions): Garlic and green onions are both foods that strongly stimulate the intestinal tract. Symptoms such as abdominal pain and diarrhea are likely to occur after eating them together.

(Tofu + spring onions): Tofu is rich in protein, calcium and other nutrients, while green onions contain a lot of oxalic acid. When tofu and green onions are combined, the calcium in the tofu combines with the oxalic acid in the green onions to form a white precipitate, calcium oxalate, which destroys the calcium in the tofu. Calcium oxalate is difficult to absorb in the human body. If you eat vegetables such as tofu mixed with green onions and stir-fried tofu with green onions for a long time, it will cause calcium deficiency in the human body and may easily lead to calcium deficiency, calf cramps, cartilage, and fractures. Some people use chopped green onion as seasoning when cooking tofu, which is also detrimental. Some vegetables containing oxalic acid, such as spinach, fresh bamboo shoots, bitter melon, etc., should be scalded in boiling water before cooking to remove most of the oxalic acid before use, to prevent the formation of calcium oxalate.

(Banana + Yogurt): Yogurt can lower cholesterol. Drinking yogurt on an empty stomach will make it difficult for lactic acid bacteria to survive in the gastric juice due to the acidity in the stomach being too strong, which will reduce the health care effect of yogurt. Eating it with bananas is not good for your health

(Spinach + Tofu): Tofu contains magnesium chloride and calcium sulfate, while spinach contains oxalic acid. When these two foods come together, they can generate oxalic acid. Magnesium and calcium oxalate cannot be absorbed by the body.

(Persimmon + Crab) - Possible vomiting and diarrhea

Crabs are rich in protein, which easily precipitates when combined with the tannins in persimmons and solidifies into substances that are difficult to digest. It has an astringent effect, so it can also inhibit the secretion of digestive juices, causing coagulated substances to remain in the intestines for fermentation, causing vomiting, bloating, diarrhea and other food poisoning phenomena in eaters.
