Ways to reduce pesticides in vegetables

Nutritionists and food safety experts say studies have shown that farmers who have been exposed to pesticides for a long time have a high risk of cancer. The longer the exposure, the greater the risk of liver cancer, and those who are exposed to pesticides are 5 to 8 times more likely to develop lymphoma.

In addition, pesticide residues can cause chronic poisoning, such as reduced immunity, infertility, causing various chronic diseases, tumors, etc. Pesticides during pregnancy and lactation will increase the incidence of birth defects.

Ordinary people can not distinguish whether fruits and vegetables have pesticides or not, but cannot not eat. Therefore, the method of cleaning fruits and vegetables is very important.

1. Peel fruit

Many fruits and vegetables have natural fruit wax on their skin, non-invasive water-soluble insecticides and fat-soluble pesticides that are only superficial. In this case, just peel and eat normally. Peeling is a very safe way to remove pesticides, with an efficiency rate of more than 90%. Of course, this method is not suitable for green vegetables, but if it is cabbage wrapped in leaves and kale, discarding 2 to 3 outside leaves is also quite safe.

2. Blanch over boiling water

Blanching with hot water is also a good way to remove pesticide residues. Using hot water, the solubility rate of pesticides is higher than cold water. In general, it is best to blanch the bulbs for 1 to 2 minutes. Many leafy greens are also suitable for this method, especially those that are high in oxalic acid. Blanching hot water can not only eliminate pesticide residues but also partially remove oxalic acid.

However, this method also has a major disadvantage that blanching hot water can cause nutrient loss in food. In fact, the vitamins and other nutrients in vegetables do not heat, normal cooking has also lost some nutrients. If you blanch the hot water before cooking, the nutrients will be lost.

3. Wash fruits and vegetables under running water

In the process of caring for fruits and vegetables, many farmers spray insecticides on leaves and stems to protect crops from damage.

Washing fruits and vegetables under running water does not simply eliminate pesticides because they are water soluble, but rubbing while washing also helps to remove impurities. Fruits like grapes, apples, strawberries, guavas, blueberries, plums, peaches, and pears, as well as vegetables like tomatoes, eggplants, green beans and okra can be cleaned using this method.
