If the food goes bad, there will be carcinogenic substances in it, which will harm the health of the human body.
-
It causes the intestines to produce a lot of harmful bacteria.
Extremely poor for health.
So don't eat mutated foods.
-
New strawberries should not be eaten too much because there is too much oxalic acid in them.
-
There's going to be mold! Eating too much can cause cancer!

Plausible. In the natural environment, plant seeds are actually mutating, but this mutation process is extremely slow and the mutation frequency is very low, which is generally called natural mutation. Most of the early plant phylogenetic breeding methods were based on the selection and utilization of this natural variation, which proved to be safe and feasible.
Space breeders consciously use the conditions of the space environment to accelerate this process of mutation of organisms, which is called artificial variation. There is no difference in nature between the two variants. The seeds (not for direct consumption) returned from the flight in space were not found to increase any radioactivity after rigorous professional testing.
Therefore, there will be no adverse reactions in eating grains, vegetables, etc., produced by space seeds.

The impact on human health in spoiled food villages is mainly manifested in the following three aspects.
1. Disgust due to the change of various components (decomposition) in food promoted by microorganisms in the process of growth and reproduction, which changed the sensory shape of food raw apricots. Makes people feel disgusted with it. For example, in the process of protein decomposition, it can produce organic amines, hydrogen sulfide, mercaptans, stomping, skatosin, etc., which have the unique odor of protein decomposition; Bacteria and stealing bacteria can produce pigments in the reproduction process, so that the food presents a variety of abnormal colors, so that the food loses its original color and flavor; The rotten "hala" of fat and the special smell produced by the breakdown of carbohydrates are also often difficult for people to accept.
2. Reduce the nutritional value of food due to the change in the structure of protein, fat and carbohydrate in food after spoilage, thus losing the original nutritional value. For example, after the decomposition of protein, low-molecular toxic substances are produced, thus losing the original nutritional value of protein: fat decay, hydrolysis, and oxidation produce peroxide, which is then decomposed into carbon-based compounds, low-molecular fatty acids, aldehydes, ketones, etc., and loses the physiological effect and nutritional value of fat on the human body; Carbohydrates spoil and decompose into cheese, aldehydes, ketones, preparations and carbon dioxide, and also lose the physiological function of plant carbohydrates.
In short, due to the decomposition of nutrients, the nutritional value of the food is reduced.
3 The whole process of causing poisoning or potential harm to food from production and sales is small, and the way and degree of food contamination are also complex There are many toxic substances produced by food spoilage, so the harm caused by spoiled food to human health is also different.
1) Acute toxicity. Under normal circumstances, spoiled food often causes acute poisoning, and mild cases mostly appear with symptoms of acute gastroenteritis, such as vomiting leaves, sadness, abdominal pain, diarrhea, fever, etc., which can be restored to health after **; Severe cases can have symptoms in the respiratory, circulatory, nervous and other systems, and timely rescue can turn the crisis into safety, and if the time is delayed, it can also endanger life. Some acute poisoning, although every effort has been made, still leaves sequelae to the poisoning.
2) Chronic toxicity or potential harm. Some spoiled foods contain less toxic substances, or due to the characteristics of their own toxic effects, they do not cause acute poisoning, but long-term consumption often causes chronic individual poisoning, and can even be manifested as carcinogenic, teratogenic and mutagenic. A large number of animal test studies have shown that:
Consumption of moldy peanuts, grains and peanut oil contaminated with aflatoxins. It can cause chronic poisoning, pathogenicity, teratogenicity, and catastrophic transformation. It can be seen that the consumption of spoiled and moldy food has extremely serious potential harm, harming human health, and must be paid attention to.

The harm of food spoilage, eating spoiled food can be fatal.
-
In general, food will spoil when it expires. After the expiration date of food, it will mainly cause two undesirable fruits: one is that many nutrients needed by the human body in the food disappear, and the other is that it may lead to the proliferation of bacteria in the food.
Therefore, the consumption of expired food can not only ensure that the human body absorbs the nutrients it needs, but also may lead to food poisoning and acute infectious diseases, and long-term consumption of expired and spoiled food may also induce cancer in some parts of the human body.

Food poisoning. Vomiting and diarrhea. Dizzy. Weakness in the limbs. Chest tightness.
Enriching the diversity of species. Excellent strains can be obtained to improve the production efficiency of the factory; It can improve the yield and quality of vegetables and grains and alleviate the food crisis.
It seems that LZ does not understand the definition of variation very well, the definition of variation in ecology or biology is, "refers to the difference between the offspring and the parents of the organism, the difference between the offspring of the individual", from this definition, the organism itself is undoubtedly mutating, because the difference between the parents and the offspring, between the offspring and the offspring from birth to this or that, the so-called "dragon born nine children are different" is also the truth. >>>More
Diagnosis of variant asthma: When encountering patients who only complain of long-term cough (more than 2 weeks), the possibility of asthma should be considered, and the diagnosis can be confirmed on the basis of excluding medical history, careful physical examination, and summarizing clinical features, combined with the following methods: >>>More
It's in the genetic algorithm"Heredity""Variation"?
The heredity of living things is relative, whereas the variation of living things is absolute.
