If you don't blanch these 6 types of food, you could be in danger!

Spinach

Spinach is a highly nutritious vegetable, rich in iron, vitamin A, vitamin C, vitamin K, and many other nutrients.

It has significant effects on promoting blood circulation, enhancing immunity, and protecting eyesight. However, spinach contains oxalic acid, an important substance related to human health.

Oxalic acid is a natural chemical that can combine with calcium to form calcium oxalate. This not only affects calcium absorption but may also lead to problems such as kidney stones.

For people who need to supplement calcium, unprocessed spinach can reduce calcium absorption and pose a threat to bone health.

Therefore, spinach should be blanched before consumption. Blanching spinach in boiling water for 3-5 minutes effectively removes oxalic acid, making it more palatable to the body.

In addition, blanching spinach not only allows it to absorb calcium better, but also helps prevent other health problems.
