Can apples washed with tap water be eaten?

What are the benefits of eating apples?

First of all, the advantage of apples is that they are rich in minerals such as vitamin C, potassium and magnesium, and rich in dietary fiber. In terms of vitamin C, because apples are generally eaten directly, unlike vegetables, there is no process of vitamin loss, so apples can consume 100% of vitamins. In dietary fiber, it can prevent some chronic diseases, such as digestive tract tumors and cardiovascular diseases, which are very common chronic diseases, and its preventive effect is very advantageous in this respect. In addition, weight gain can be controlled. Apple has a characteristic that it contains some organic acids and tastes sour. For example, malic acid is one of the ingredients, which can stimulate the secretion of digestive glands, promote appetite for people with poor appetite, promote digestion for people with indigestion and protect the stability of vitamin C intake, so it is a very advantageous fruit.

Apple has the reputation of "wisdom fruit" and "memory fruit". People have long found that eating more apples can improve memory and intelligence. Apples are not only rich in essential nutrients such as sugar, vitamins and minerals, but also rich in zinc. According to research, zinc is a component of many important enzymes in human body and a key element to promote growth and development. Zinc is widely involved in the metabolism of protein, fat and sugar in the body through enzymes. Zinc is also an essential element of protein and nucleic acid closely related to memory. Zinc deficiency can make the hippocampus on the edge of cerebral cortex stunted and affect memory. Experiments have also proved that reducing zinc in food will seriously hinder children's memory and learning ability. Zinc is also closely related to the production of antibodies and the improvement of human immunity.

tap water

There are two ways to use tap water:

One is surface water with many impurities, which is usually precipitated, filtered and dosed.

One is groundwater with high mineral content and good water quality. Generally, just add some liquid chlorine.

Water from the waterworks. Despite various treatments, some organic substances and free chlorine still combine to form carcinogenic precursor trihalomethane, on the other hand, it becomes a culture medium for microbial reproduction. The regenerated microorganisms form biofilms in the water distribution pipeline all the year round. The aging and falling off of the membranes lead to the increase of the smell, taste and chromaticity of water used by users. The microorganisms on this pipeline network gradually become resistant to disinfectants and are not easy to be killed, further increasing the number of microorganisms in the terminal tap water. There are as many as 2 1 species of bacteria detected on surface residues and washed granular sediments in water supply networks abroad.

Second, in the transmission and distribution network system, the secondary pollution of intermediate water tank is serious.

According to statistics, there are 70,000 intermediate water tanks in Shanghai, more than 0,000 in Guangzhou 1 1, and many in other cities. Due to long-term exposure to space, poor sealing and poor management, bacteria, viruses, protozoa and algae in these tanks proliferate and pollute the water quality. Every year in Guangzhou, it is reported that red worms are found in domestic tap water, which is caused by the intermediate water tank. In addition, some dead mice and pigs were found in some intermediate water tanks, and the bodies of these rotting animals will increase the foul smell and sour taste of the water.

Presumably, everyone should know the answer when they see this.

So how to clean the fruit to be clean, safe and hygienic?

1 When washing apples, first wash the surface peel with salt, then soak it in baking soda for five minutes, and finally clean it.

2 Wash with starch

Wash with hot water

In fact, you can steam the apples, eat them, cut them into your favorite shapes, and steam them in a steamer for ten minutes, so the nutrition will not be lost! ! !
