Do you want to eat the food that falls on the ground?

Food that falls on the floor is generally not allowed to be eaten.

It depends on the type of food that falls on the ground. Food that falls on the floor can easily cause the food to be stuck to it by dust, and may also fall on corrosive acidic parts, in which case it is not allowed to eat, such as biscuits and bread food, which may also affect the taste and cause bacteria to grow. Researchers at Aston University in the United Kingdom said that eating food on the floor of the home is very unlikely to cause illness, and it is no problem to pick up and eat biscuits, chocolates and other foods after falling on the floor for half an hour.

Food refers to substances that can meet the body's normal physiological and biochemical energy needs and extend normal lifespan. For the human body, the substance that can meet the needs of normal life activities and help prolong life is called food.

Food is usually composed of carbohydrates, fats, proteins, and water, which can provide nutrients for humans or living beings by eating or drinking

People take food as the sky, food safety as the first", which is enough to prove that people attach importance to food safety and hygiene. If there is a hygiene problem with the food, it will inevitably pose a certain health threat to the body.

However, there are two sides to everything, and many people think that food that is too clean will have a bad effect on the body. Therefore, there has been a saying among the people, "If you don't do it, you won't get sick if you eat it".

So, is there any scientific basis for this kind of talk?

What does it mean to not dry it cleanly, and you will not get sick if you eat it?

As for the saying that "if you don't dry it, you won't get sick if you eat it", many people think that sometimes in an overly hygienic and clean environment, it is easy to get sick. This kind of remarks is a well-known "health hypothesis" in immunology, which mainly refers to "exposure to some exogenous potential allergens in the early stages of life, which helps the body to develop immune tolerance; Living in an excessively clean environment can lead to deficiencies in immune tolerance, which increases the risk of allergic and autoimmune-related diseases later in childhood."

It is worth noting that any doctrine and theory needs to be considered "in the light of reality" and cannot be viewed one-sidedly. If you don't pay attention to your diet and hygiene just to prevent allergic diseases that may arise, this "consequence" will be uncontrollable.

It is not clean, and it can strengthen immunity.

There are also people on the Internet who say that "the impurity in life can enhance the body's immunity". In fact, these only see the response of the body's immune system to a single microorganism, but the quality of the microorganism (whether it is pathogenic or not) is unknown, and the type and number of microorganisms are unknown.

Therefore, to maintain or enhance the body's immunity, we should rely on healthy eating habits and good living habits.

If the food falls to the ground, can you still eat it when you pick it up?

After the food falls on the ground, whether it can be eaten depends on whether the food is infected with pathogenic bacteria, the total number of colonies, and one's own immunity. If you don't have diarrhea or other symptoms after eating food that fell on the floor, you may not have been exposed to pathogenic bacteria, or your body's immunity is good. However, from a safety point of view, it is not recommended to try, once you get hit, the gains outweigh the losses.

If there happen to be pathogenic bacteria, and if you happen to pick them up and eat them, it will greatly increase the risk of illness (some E. coli can cause food poisoning in small amounts, and even lead to death). Therefore, it is not recommended to continue eating food regardless of how many seconds the food has been in contact with the ground.
