1, onion. Although soybean sprouts and onions have no dietary taboos, some active substances contained in onions may affect the absorption and utilization of plant protein in soybean sprouts, resulting in nutrient loss.

2. spinach. Spinach contains a certain amount of oxalic acid, while soybean sprouts are rich in calcium. When a large amount of oxalic acid meets calcium, a chemical reaction may occur, and then calcium oxalate will be formed, resulting in the loss of calcium. Moreover, calcium oxalate is a water-insoluble substance, and too much calcium oxalate is likely to form stones.

3. Pig liver. Pig liver contains copper, while soybean sprouts contain extremely high vitamin C. Eating pig liver and soybean sprouts at the same time may lead to the oxidation and reduction of vitamin C, thus affecting the nutritional value of food.
