Why can t spinach and tofu be eaten at the same time?

Tofu is high in protein and rich in calcium, making it a healthy food that is recommended to be used. Spinach is rich in various nutrients, but also contains high oxalic acid, when the two foods are cooked together, if the calcium meets oxalic acid, it will form calcium oxalate that cannot be absorbed and utilized by the human body.

Correct processing method: Before cooking, blanch the spinach with water to remove the oxalic acid in the spinach, and then fry it with tofu, which is delicious and has high nutritional value.

Theoretically, it is unscientific to eat like this, and the oxalic acid in spinach will combine with the calcium in tofu to form calcium oxalate stones, which will destroy the nutrients and reduce the value. But in fact, it can be eaten together, for example, green onion tofu, green vegetable tofu, etc. are very famous home-cooked recipes, Chinese have eaten for thousands of years, and no one has seen malnutrition after eating.

The two cannot be combined. Spinach contains oxalic acid, and when making tofu, gypsum (calcium sulfate) is put in it, and tofu contains calcium, and if it is put together, oxalic acid will have a chemical reaction with calcium ions to produce calcium oxalate that is insoluble in water, which cannot be absorbed by the human body at all, and will accumulate in the human body, and may also form stones, which is seriously harmful to health.

Spinach and tofu characteristics: Spinach and tofu can't be eaten together After decades of publicity, this sentence has become a household name and an iron law deeply rooted in the hearts of the people. However, according to the research results in recent years, it can be concluded that spinach and tofu are not only a good match, but also a perfect match for calcium and bone strengthening.

Can spinach and tofu be eaten together?

No, but blanching the leafy vegetables before stir-frying and removing some of the oxalic acid will solve the problem.

Tofu contains calcium, spinach contains oxalic acid, and eating the two together will form calcium oxalate, which is easy to get stones. In fact, most leafy vegetables such as oilseed rape, bok choy, amaranth, etc., contain oxalic acid.

The precipitate formed by the combination of calcium and oxalic acid is eventually excreted from the body and does not enter the bloodstream. Of course, this reaction will reduce the utilization of calcium in tofu. Blanching the leafy vegetables before stir-frying and removing some of the oxalic acid can solve the problem.

Can spinach and tofu be eaten together?

Spinach is not suitable for eating with tofu.

Eating spinach and tofu together can easily lead to stones.

1. Spinach food restraint

1. Tofu:

Tofu contains magnesium chloride and calcium sulfate, while spinach contains oxalic acid, and magnesium oxalate and calcium oxalate can be formed when the two foods come together. These two white sediments will not only affect the normal absorption of calcium by the human body, but also easily lead to stones.

2. Cucumber: Cucumber contains vitamin C decomposition enzyme, and spinach is rich in vitamin C, so cucumber and spinach can not be eaten at the same time, otherwise the vitamin C in spinach will be destroyed by the decomposition enzyme in cucumber.

3. Milk: Because spinach contains tannic acid, milk contains protein, and it will react and is not easy to digest, some people are prone to diarrhea after eating.

Vegetables and fruits containing more oxalic acid, such as spinach, will combine with calcium to form insoluble precipitates, which will affect the absorption of calcium in milk, so spinach and milk should never be eaten at the same time.

Eating spinach with milk can cause dysentery.

4. Cheese: Spinach and cheese are compatible. The chemical composition of cheese affects the absorption of the calcium rich in spinach.

5. Pork liver: Because spinach contains vitamin C, pork liver is rich in metal elements, such as copper, iron, etc. Eating the two at the same time is easy to make the vitamin C in spinach lose its nutritional value.

Pork liver is rich in copper, iron and other metal elements, once combined with spinach with high vitamin C content, metal ions can easily oxidize vitamin C and lose its own nutritional value. Animal liver, egg yolk and soybean are rich in iron, and should not be eaten with amaranth and spinach containing more oxalic acid. Both cellulose and oxalic acid can affect the body's absorption of iron from these foods.

6. Eel: Eating spinach and eel together can easily cause diarrhea. The eel has a sweet and warm taste, which has the effect of nourishing qi and nourishing blood, strengthening the spleen and kidney, invigorating qi and strengthening the membrane, removing stasis and removing dampness; And spinach is sweet and slippery, moist and dry, "Compendium of Materia Medica" cloud:

Stomach and intestines are hot. "Obviously, the two are not in harmony with each other. And the eel is greasy and fatty, and the spinach is cold and slippery, and eating it together can easily cause diarrhea.

7. Nine vegetables: Since spinach and nine vegetables have the effect of moistening the intestines and laxative, eating them at the same time will promote intestinal peristalsis, which can easily lead to diarrhea and abdominal pain.

8. Soybeans: Spinach and soybeans are eaten at the same time, and the vitamin C in spinach will inhibit the absorption and excretion of the metal element copper, and is not conducive to human digestion.

Second, tofu food is restrained

1. Spinach: Because tofu contains magnesium oxide and calcium sulfate, while spinach contains oxalic acid, these two substances can produce magnesium oxalate and calcium oxalate at the same time. Both cannot be absorbed by people at the same time, and stones are prone to occur.

2. Bamboo shoots: Eating tofu and bamboo shoots together will destroy the nutritional value and may also produce stones.

3. Honey: Honey is sweet, cool and smooth. Eating it with tofu can easily cause diarrhea.

4. Callus white: Eating it with tofu is also easy to form stones.

5. Brown sugar: Because brown sugar contains a variety of organic acids, it is easy to denature and precipitate proteins due to the combination of protease in tofu, and is not easy to be absorbed.
