Vegetables provide us with abundant nutrients

Food ingredients are washed before cooking
But, do you really know how to wash vegetables?
Some seemingly ordinary habits of washing vegetables
It's not scientific
Not only can it not effectively remove dirt
It can also greatly reduce the nutritional value of vegetables
Common but wrong ways to wash vegetables
1. Soak vegetables for a long time
Prolonged soaking softens the vegetable's cell walls, making it easier for pesticides and other contaminants to penetrate the vegetable. In addition, some water-soluble vitamins can also dissolve in water, causing nutrient loss.
2. Use too much detergent
If the chemical components in the detergent are not cleaned thoroughly, they will remain on the surface of vegetables, causing secondary pollution and affecting health. In addition, in some experiments, the effect of using detergent to clean vegetables is not as good as that of clean water.
3. Cut first and then wash
Cutting vegetables before washing not only accelerates nutrient loss, but also increases the risk of contamination by bacteria, dust, pesticide residues, etc.
4. Vegetable washer
Ultrasonic cleaning of leafy vegetables by vegetable washer is not ideal, pesticide removal rate is only 53%, inefficient, and not all types of pesticide residues can be removed. If you go to a regular supermarket to buy vegetables, under normal circumstances, most of the pesticide residue content meets the relevant standards and norms, so there is no need to panic and worry too much.
