Can you still eat cabbage with black spots, can you eat cabbage with black spots

Whether you can eat it if there are black spots on the cabbage, this depends on the actual situation:

1. Black spots that can be washed off with water.

For example, soil, particulate matter in the environment, insect feces, etc., are all black spots on vegetable leaves that can be washed off, and generally there is no problem as long as they are cleaned, and they can be eaten with confidence.

2. Small black dots that can't be removed.

The reason why this small black spot cannot be cleaned off is because the black dot grows inside the cabbage fiber. This is actually a manifestation of cabbage disease, so it is also called cabbage disease.

Under normal circumstances, cabbage with such small black spots is still edible, but if it is accompanied by a bitter taste when eaten and the mouth is numb after eating, it is best not to eat it, because it may be too much residue of chemical fertilizer.

Note what is said here"Small black dots", the big ones are another matter.

If you have this disease from the cabbage you grow at home, it may be due to two reasons:

First, nitrogen fertilizer is applied too much; Second, the environmental problems of cabbage growth, such as drought, low temperature, soil nutrient deficiency, etc., will cause cabbage to lack calcium, resulting in the growth of small black spots.

3. Big black spots or dark spots that can't be removed.

This kind of big black spots or black spots may be spoiled or mildewed in the cabbage, and you must not eat it in this case!

Because this cabbage produces harmful substances such as nitrite, nitrite is known to cause food poisoning if eaten too much.

Can't eat. The steamed bread has black spots, which is the manifestation of the mold breeding in the steamed bread, which is harmful to the body, and its mycelium not only exists in the black spots visible to your naked eye, but also may be inside the steamed bread, so the steamed bread has black spots to throw away, can not continue to eat, even if the black spots are removed, it is not edible, there is still a risk of health hazards.

When nitrite enters the bloodstream, it oxidizes low hemoglobin to methemoglobin, depriving the blood of its ability to carry oxygen. Do not eat cooked cabbage overnight, because the cabbage will reduce nitrate to nitrite through bacterial action during the time it has been placed.

This is because these black spots will appear when the cabbage is left out for a long time. In such a situation, the cabbage cannot be eaten.
