Can spinach be eaten raw?
Spinach can't be eaten raw because spinach contains more oxalic acid, which will combine with calcium in the intestine to form insoluble calcium oxalate, which interferes with the absorption of calcium by human body. So even if it is cold, it must be boiled with boiling water to remove most of the oxalic acid.
Is spinach to lose weight?
Yes, nutritionists say spinach is the most nutritious spinach. Eating spinach can help you lose weight and stay healthy easily. Spinach is rich in cellulose, which can help digestion and promote gastrointestinal peristalsis. After eating, it can not only maintain great strength, but also reduce fat, thus achieving the effect of losing weight. In addition, spinach contains potassium, which can induce diuresis and relieve constipation, and can also help to lose weight.
Why should spinach be blanched?
Spinach is rich in oxalic acid, which is a common organic acid. After eating, it will react with minerals such as calcium and magnesium contained in other foods, and generate some precipitated substances such as calcium oxalate and magnesium oxalate, which is not conducive to gastrointestinal digestion and will reduce the nutritional value of spinach. Excessive consumption for a long time may lead to stones. Therefore, it is recommended to eat spinach blanched.
Spinach needs blanching for a few minutes.
Long 1-2 minutes. Generally, the blanching time is too short and the blanching effect is too small. If blanching time is too long, water-soluble nutrients will be lost more. The blanching time of different vegetables is different. For broccoli, blanching for 3 minutes is usually enough. However, since spinach has been blanched before being put into boiling soup or wok, the heating should be stopped within 1 min to avoid overcooking and making spinach leaves soft and rotten.
