In our diet, we have countless ways to prepare food, but a few common home-cooked dishes almost always appear on the dining table. Did you know that some familiar dishes like "Scallion Tofu" and "Tea Eggs" can actually be detrimental to your health? Below, we share 6 common unhealthy food pairings to help you reclaim a healthy lifestyle.
We have a saying: "Scallion and tofu, one clear and one white." Indeed, scallion tofu, as a common home-cooked dish, is deeply ingrained in our culture. But did you know this pairing is actually incorrect? Eating too much of it can damage your health and even lead to serious illnesses.
1. Scallion and Century Egg Tofu Salad (Tofu, Scallion)
Tofu is rich in nutrients like protein and calcium, while scallions contain a large amount of oxalic acid. When tofu and scallions are combined, the calcium in the tofu reacts with the oxalic acid in the scallions to form white precipitate, calcium oxalate, which destroys the calcium in the tofu. Calcium oxalate is difficult for the human body to absorb. If dishes like scallion tofu or stir-fried tofu with scallions are consumed for a long time, it can lead to a calcium deficiency in the body, making one prone to conditions like calcium deficiency, leg cramps, osteomalacia, and fractures. Some people use chopped scallions to season tofu when cooking, which is also not advisable. For vegetables containing oxalic acid, such as spinach, fresh bamboo shoots, and bitter melon, it's best to blanch them in boiling water first to remove most of the oxalic acid before cooking. This can prevent the formation of calcium oxalate.
2. Spicy and Sour Cucumber with Cold Jelly (Cucumber, Chili Pepper)
Cucumbers contain vitamin C decomposing enzymes, which can destroy the vitamin C in chili peppers, reducing their nutritional value.
3. Banana Yogurt (Banana, Yogurt)
Yogurt can help lower cholesterol. Drinking yogurt on an empty stomach is not ideal because the high acidity of the stomach acid makes it difficult for lactic acid bacteria to survive, reducing the health benefits of the yogurt. Eating it with bananas is also not beneficial for your health.
4. Five-Spice Tea Eggs (Tea, Eggs)
Strong tea contains a significant amount of tannic acid. Tannic acid can cause proteins in food to become indigestible coagulated substances, affecting the human body's absorption and utilization of protein.
5. Braised Pork Trotters with Soybeans (Pork Trotters, Soybeans)
The alduronic acid residues in the dietary fiber of soybeans can chelate with the minerals in pork trotters, interfering with or reducing the body's absorption of these elements.
6. Spinach and Tofu Soup (Spinach, Tofu)
Tofu contains magnesium chloride and calcium sulfate, while spinach contains oxalic acid. When these two foods are combined, they form magnesium oxalate and calcium oxalate, which cannot be absorbed by the human body.
