Will eating temporary food for a long time harm your health?

Long-term consumption of temporary food will not harm health, as long as the quality we buy through formal channels is guaranteed, it will usually not affect health.

Temporary food must be familiar to most of us. Temporary food is food that is near the shelf life, but still within the shelf life. Every time we go to the supermarket, we will always see some discounted foods, such as yogurt, biscuits, bread and various snacks, which are often much cheaper than the original price. However, during the shelf life of temporary food, it will not cause harm to health and will not reduce food safety. Temporary food is no longer a "bad" food, but a change in people's consumption concept. Since everyone likes temporary food so much, today we will talk about temporary food.

1. Will eating temporary food for a long time affect your health?

1, whether eating temporary food for a long time will affect health should actually be divided into different situations, and even more factors may be considered.

Generally speaking, on the premise of ensuring the quality of food, temporary food can be eaten as long as it is in a normal state and flavor. Especially for foods with a long shelf life, as long as they are not opened, they are on the verge of expiration or overdue for several weeks, and the quality will basically not be affected. For example, vacuum-packed food can be eaten even in its infancy. Just like the coffee beans I bought at home, I'm still drinking (? ~)。

2. Will eating temporary food for a long time affect your health? If the quality is guaranteed, it will generally not affect your health. But there are two situations that need attention:

First, food quality information is asymmetric.

For example, in order to reduce waste and increase sales, some businesses will tamper with the shelf life at will. Expired bread or other foods will be sold after the modification date, which makes consumers unable to better identify the quality of food.

In addition, it is difficult for consumers to distinguish the specific content of food ingredients, so it is difficult to judge whether food is beneficial to consumers. We can only acquiesce that the ingredients on the food ingredient list are the nutrition of the food itself.

Second, some foods that are inherently unhealthy or have low nutritional value, even if they are eaten for a long time within the shelf life, let alone expired or expired.

Once the fruits and vegetables rot, the virus has spread everywhere, which will affect health.

As essential ingredients in people's diet, fruits and vegetables are naturally kept at home. After buying home, fruits and vegetables will be dehydrated or partially rotted due to factors such as temperature, humidity and storage methods. In order to avoid waste, some people will cut off the rotten parts and continue to eat.

Let me emphasize here: in fact, fruits and vegetables with rotten parts removed still contain a lot of bacteria and harmful substances. Removing the bad parts does not mean that the microorganisms are removed together. They are still lurking in the seemingly complete part of the pulp to grow and reproduce! Harmful substances mainly penetrate and spread to non-rotting parts through juice in fruit juice and vegetables. When we eat this food, we are likely to have dizziness, nausea, vomiting and diarrhea, and even coma in severe cases. Especially after the fruit is moldy, it will produce a lot of Penicillium toxin, which will cause damage to people's nervous system and respiratory system, causing nerve paralysis, pulmonary edema, renal failure and so on.

Therefore, combining the above points, whether the temporary food will affect health needs to be treated dialectically.

Second, which temporary foods are not recommended to be eaten often?

Accurately speaking, these foods are not recommended to be eaten often, even if there is no shelf life, such as potato chips, candy, sweet drinks and so on. In addition, it is not recommended to eat non-vacuum packed nut snacks, because fresh nuts contain a lot of oil, and over time, fat oxidation will be more serious, and the content of vitamin E will be less and less, and the smell is pungent, so it is not recommended to eat.

It is recommended to buy chilled fresh food. Especially in summer, the temperature of refrigerated or frozen food is not up to standard, which can easily shorten the "life" of food. Another situation is that because we buy too much, the food is on the way or expired. If it is not well preserved or has gone stale and moldy, it is recommended that you do not continue to eat it.

Third, which "expired foods" can be eaten?

1, frozen food:

As mentioned above, frozen food is easy to deteriorate due to the weather, but it is edible if the freezing facilities are in good condition and there is no quality problem.

2, biscuits, oats and other low-moisture foods:

Because of lack of water, they can be preserved for a long time. If it becomes hard or soft after long-term storage, which affects the taste, you can give up eating.

3. Yogurt:

Refrigerated yogurt can be drunk as long as it meets the refrigeration conditions and its taste and appearance have not changed.

4. Canned food:

As a result of sealed packaging and high temperature heating, the bacteria in the can are all killed, and will not deteriorate as long as they are not opened. Foods that are hot-canned with high acid and ultra-high temperature sterilized drinks will not go bad as long as they are not opened.

When we buy temporary food, we should make sure that the food packaging is intact and the goods have not gone bad or deteriorated. We should also eat goods as soon as possible after buying them.
