Can drinking yogurt protect against computer radiation? Don’t exaggerate the claim…

Yogurt tastes sweet and sour and is nutritious. People with lactose intolerance will not get diarrhea after drinking yogurt. It is very popular among people, especially in summer. Cool yogurt is regarded by many people as a "magic weapon to relieve summer heat."

Recently, a netizen said, "Drinking yogurt in the morning can absorb nutrients, drinking yogurt at night can supplement calcium, drinking yogurt after using the computer can have the most obvious radiation protection effect, drinking yogurt in the afternoon can replenish energy, and drinking yogurt after a meal is best for the stomach." Is this true? Today's nutrition class will tell you whether yogurt can prevent radiation and how to drink it more healthily.

Is drinking in the morning more conducive to nutrient absorption?

Many people say that yogurt is best to drink in the morning. In fact, the nutritional value of yogurt will not change whether it is morning, noon or evening.

The nutritional characteristics of yogurt are that it is rich in high-quality protein and calcium. For most people, drinking yogurt and eating dairy products is mainly to take in the calcium.

If the nutrients are better absorbed in the morning as the above netizens said, then the calcium and protein should be absorbed in the morning, but the netizens also said that drinking yogurt at night is the best for calcium supplementation. This is obviously contradictory.

As for drinking yogurt in the afternoon to replenish energy, protein and calcium do not have such a big impact on energy. Replenishing energy mainly replenishes sugar. Eating it at any time can replenish blood sugar and enhance energy.

In general, there is no need to worry about when to drink yogurt. The specific time to drink it mainly depends on your personal lifestyle. You can drink it whenever you want.

Is drinking yogurt after a meal good for your stomach?

The above netizen said that "drinking yogurt after a meal is best for the stomach." This statement is not accurate. On the contrary, drinking some yogurt while eating may be more conducive to digestion.

Generally speaking, drinking yogurt while eating, because it is mixed with other foods, can prolong the time that yogurt stays in the digestive tract, thus slightly helping the body to absorb the calcium in the yogurt.

Moreover, the lactic acid in yogurt may stimulate our appetite, promote gastric acid secretion, and accelerate the digestion and absorption of food.

Can drinking yogurt prevent computer radiation?

The statement that "drinking yogurt after using a computer is the most effective in preventing radiation" is obviously a completely unreliable recommendation.

First of all, there is no such thing as radiation-proof food.

In the field of health, scientists have indeed done a lot of research to find food ingredients that can reduce the damage of "radiation" to the body. However, the research is generally aimed at ultraviolet rays, X-rays and other radiation.

Although scientists have found that food ingredients such as vitamin C, vitamin E, carotene, polyphenol compounds in plants and even polysaccharides may play a role in radiation protection in animal experiments, there has been no particularly sufficient evidence for these effects. Moreover, these ingredients themselves are regular nutrients needed by the human body. Regardless of whether they can resist radiation or not, eating them appropriately is good for the human body. Even if you deliberately eat too much, no extra benefits have been found.

Secondly, the impact of computer radiation on human health is minimal and there is no need to worry.

The main sources of low-frequency electromagnetic fields in our lives are power supplies and electrical appliances. In almost all normal environments, the intensity of the induced current in the body is so small that it will not produce any noticeable effect. So far, there is no evidence to confirm that exposure to low-intensity electromagnetic fields will cause health effects.

How to drink yogurt healthily?

Yogurt is actually a dairy product made by fermenting lactic acid bacteria. After fermentation, the lactose in the milk is broken down. In other words, you don't have to worry about lactose intolerance when drinking yogurt. There are three suggestions for drinking yogurt:

First, drink in moderation. Milk and dairy products are one of the food varieties recommended by the dietary guidelines for Chinese residents to consume daily. It is recommended to consume 300-500 grams of dairy products every day. Yogurt is also a good dairy product. If you are lactose intolerant, you can use yogurt as a substitute.

Secondly, if you drink it at home regularly and it is convenient to store it in the refrigerator, you can buy low-temperature yogurt; if refrigeration is not convenient, you can buy room-temperature yogurt.

Third, give priority to big-brand yogurt. You can buy big-brand yogurt on the market with confidence. Big companies and big brands generally have better food safety control. It should be reminded that you should try to buy it in regular channels such as large supermarkets. In addition, after buying yogurt home, drink it as soon as possible or store it in the refrigerator.
