Vegetarianism - spinach with Tofu

Introduction:

Many people believe that spinach and tofu can't be eaten together. What is the reason for this taboo? There is only one theoretical basis: spinach contains a lot of oxalic acid, while ordinary tofu is made of gypsum or brine, which contains a lot of calcium. Oxalic acid and calcium can combine to form insoluble precipitation. So, how harmful is it? There are two popular sayings: it wastes the calcium in tofu; oxalic acid and calcium combine to cause kidney stones. However, another aspect of the problem is: if you don't eat tofu together, will the oxalic acid in spinach not be absorbed? After absorption, will it not affect the utilization of calcium and promote the formation of stones? If you worry about oxalic acid, can't you eat spinach? Then, there are many other oxalic acid rich vegetables in the diet, such as bamboo shoots, water spinach, agaric, amaranth, cowhide, water bamboo, green garlic and so on, which may also cause the problem of increasing oxalate. Can't they be eaten? To analyze these problems, we can consider from four aspects. First, can oxalic acid be removed? Without oxalic acid, all the problems will be solved. Whether spinach tofu will bring trouble depends on how the dish is made. If spinach is not blanched in boiling water and fried directly with tofu, it is possible to increase the absorption of oxalic acid. The results showed that the increase of oxalate in urine of spinach after blanching was smaller than that of directly fried spinach. When blanching, water should be a little more, and sufficient drainage can fully remove oxalic acid. Stir fry tofu first, then add blanched spinach, turn a few times, you can greatly reduce the trouble caused by oxalic acid, and keep spinach tofu delicious. Secondly, it depends on the total amount of oxalic acid consumed in a day. If spinach is blanched, but in addition to eating spinach, but also eat other vegetables containing a lot of oxalic acid, together, may still bring the problem of excessive oxalate, increase the oxalate content in urine. Third, look at the digestion and absorption function and acid-base balance of the human body. Intestinal dysfunction will increase the body's absorption of oxalate, and acid constitution will also promote the formation of oxalate crystals. Studies have shown that in vegetarians without animal protein, although the content of oxalate is high, the risk of stones is very low; eating too much meat, white rice noodles and sugary food will promote the body to become acidic, thus increasing the risk of stones. Fourth, oxalic acid rich vegetables and tofu together, whether it will increase the risk of stones. The investigation of medical circles in China has proved that taking more calcium is conducive to preventing the formation of kidney and urinary tract stones. That is to say, after eating spinach, if you don't eat bean products rich in calcium, the risk of stones is greater. [Spinach Eating mistakes] when frying spinach, some people wash the spinach and cut it into sections, then directly put it into the pot and stir fry it alone or with the meat. In fact, this method hinders the absorption of nutrients. Because spinach contains oxalic acid and calcium, oxalic acid combines with calcium to form precipitate, which becomes calcium oxalate and cannot be absorbed by human body. Especially when spinach is fried with food rich in calcium, it is more disadvantageous. The correct way is: when frying spinach, blanch it with boiling water first, remove it and drain it before frying. In this way, most of the oxalic acid can be eliminated and calcium oxalate that is not absorbed by human body can be prevented. At the same time, blanching spinach can also remove astringency. "

Production steps:

Step 1: raw material drawing

Step 2: wash spinach and blanch

Step 3: chop to size

Step 4: cut tofu into pieces, boil water in a pot, add a little salt and blanch for 3 minutes

Step 5: drain the watered tofu and crush it

Step 6: add chopped spinach

Step 7: add appropriate amount of salt, steamed fish, soy sauce, black pepper and mix well

Step 8: use a bowl to make a small spinach tofu tower. When eating, sprinkle sesame and sesame oil

Materials required:

Spinach: 250g

Tofu: 200g

Sesame: 1 handful

Salt: right amount

Soy sauce: proper amount (steamed fish and soy sauce)

Black pepper: moderate

Sesame oil: appropriate amount

Note: when frying spinach, first use boiling water to heat spinach, then remove the water and stir fry. This can eliminate most of the oxalic acid and prevent calcium oxalate that is not absorbed by human body. At the same time, heat spinach to remove astringency.
