Can spinach be added with vinegar?

I believe everyone has eaten spinach. It is a green leafy vegetable with high nutritional value and is also a vegetable that many people like to eat. Of course, although spinach is delicious, there are still many things to pay attention to during the cooking process. For example, you cannot add vinegar when stir-frying spinach. Why is this? Let us introduce the specific reasons in detail below!

1. Can I add vinegar when stir-frying spinach?

It is recommended not to add vinegar or other things when stir-frying spinach, as it will destroy the nutritional value of spinach. Spinach is rich in vitamin C, carotene, protein, and minerals such as iron, calcium, and phosphorus. In fact, spinach does not have the highest iron content and cannot replenish blood. Because only 1% of the iron in spinach is absorbed in the intestines, 90% is combined with oxalic acid, which is not only difficult to absorb, but also affects the body's absorption and utilization of iron. Therefore, spinach is not a good blood tonic.

2. Which foods should not be added with vinegar?

Not only spinach, but also try not to add vinegar when stir-frying other green vegetables. Because the magnesium ions in the chlorophyll in green vegetables react chemically with acetic acid to form pheophytin, which not only loses its original green color but also reduces its nutritional value.

In addition, it is also not suitable to add vinegar to some other dishes: do not add vinegar when stewing bone soup. Although stewing bones with vinegar can increase the dissolution of minerals, the minerals are converted into inorganic ions in an acidic environment, affecting absorption; do not add vinegar when cooking sea cucumbers. Because sea cucumbers are rich in collagen, adding vinegar during cooking will destroy the molecular structure of the protein and affect the taste; do not eat vinegar immediately after drinking milk. Because milk is a colloidal compound and has a certain degree of acidity, the organic acid in vinegar will make milk difficult to digest and absorb, especially for people with weak stomachs, which is more likely to cause indigestion.

1. Clear the intestines and promote bowel movements, prevent and treat hemorrhoids: Spinach contains a large amount of plant crude fiber, which can promote intestinal peristalsis, facilitate defecation, and promote pancreatic secretion. It has therapeutic effects on hemorrhoids, chronic pancreatitis, constipation, anal fissure and other diseases;

Ensure nutrition and improve health: Spinach is rich in carotene, vitamin C, calcium, phosphorus and a certain amount of iron, vitamin E and other beneficial ingredients, which can provide the human body with a variety of nutrients; the iron it contains has a good auxiliary therapeutic effect on iron deficiency anemia;

4. Promote human metabolism: The trace elements contained in spinach can promote human metabolism and improve physical health. Eating lots of spinach can reduce the risk of stroke.
