Is the "poisonous eating method" in food credible

Recently, it is said on the Internet that some foods will be poisoned if eaten together? Is the 'poisonous eating method' in the food credible? Some foods are compatible with each other, but some foods will not cause harm to the body if eaten together. See how experts comment on these eight rumours.

Is the 'poisonous eating method' of the legendary food reliable

Myth 1: bean curd mixed with shallot makes calcium difficult to absorb

Experts comment: almost all plants contain oxalic acid. According to this theory, as long as you eat tofu on the same day, you can't eat any more vegetables. Otherwise, you may have the same 'Cup Set' as shallot. Oxalic acid and calcium do generate calcium oxalate in vitro, but the problem is that we don't use a jin of shallot to mix a jin of tofu when cooking. In addition, the oxalic acid content in plants is very low, and tofu mixed with a small amount of shallot is not enough to combine into calcium oxalate.

Rumor 2: potato and beef cause gastrointestinal disorders

Experts comment: it's nonsense to say that potatoes are harmful to beef. With the participation of gastric acid, the protein contained in beef is initially decomposed by pepsin in gastric juice to form chyme, which is easy to be absorbed by human body in small intestine. Potato is mainly composed of starch, the concentration of gastric acid required is lower than that of meat, but any food will change the concentration of gastric acid when digested. It can't be inferred that the gastrointestinal dysfunction, or even the "toxic" of potatoes and beef, can be inferred based on the "different concentration of gastric acid required for digestion, which will prolong the retention time of food in the stomach".

Rumor 3: red and white radish eat together to destroy vitamin C

Experts comment: the so-called "carrots" should refer to carrots. First of all, the content of vitamin C in radish is very limited. Secondly, the ascorbate enzyme contained in carrot is easy to be decomposed by heating. So if we must protect the vitamin C in the radish, we might as well heat the carrot first, boil, fry and stew it, then eat the radish.

Myth 4: seafood and fruit produce arsenic

Expert comments: seafood and fruit eat together, to produce arsenic, must have two premises: first, a large amount of vitamin C in a short period of time, generally thousands of Mg or more; second, seafood is polluted by arsenic pentoxide. These two conditions are hard to meet at the same time in reality.

Rumor 5: boiled eggs with tea are more stomach stimulating

Expert comment: when doing experiments, high concentration of theophylline can combine with iron under certain experimental conditions. However, the iron content in eggs is not high, and the chance of the above reaction is very low when boiling tea eggs.

Rumor 6: soymilk and eggs lose their nutritional value

Experts comment: there is antitrypsin in soymilk, which will hinder digestion, which is also the reason why drinking raw soymilk will cause diarrhea. But the egg contains the viscous protein also can affect the absorption, therefore we also do not advocate eating the egg raw. However, when heated to a certain degree, these components will be destroyed. Therefore, as long as hot soymilk can be boiled, there is no problem in nutritional value and human health.

Rumor 7: milk and orange can cause diarrhea

Expert comment: This is not true. If so, the protein structure of meat and even rice is similar to that of milk. If you follow this logic, you can't eat fruit after eating, or you may have diarrhea.

Rumor 8: goiter caused by eating radish and fruit together

Experts comment: it is said that radish and fruit eat together, the flavonoids in fruit will inhibit the anti thyroid substance thiocyanate in radish. In fact, thiocyanate only affects thyroid function in the case of iodine deficiency in the body. If iodine intake is normal, eating radish and fruit is OK.
