Is it unhealthy to exercise after meals?


As autumn gets stronger and the weather turns colder, many people feel a lot of appetite. Eating a lot, handsome men and women who pay attention to their body can’t help but want to increase the amount of exercise. In addition to busy work, the time for exercise is basically next to the meal time. I heard that it is not suitable to exercise within half an hour or an hour after a meal. What should I do?

the truth

There is no scientific basis for the claim that exercise after meals is unhealthy, and the feasibility of exercise after meals varies from person to person.

The reason why the saying that exercising after meals is unhealthy is widespread is that many people are prone to indigestion . Indigestion is a chronic, recurring feeling of pain or discomfort in the upper abdomen, colloquially speaking, an upset stomach after eating. According to statistics, the incidence of indigestion is very high, and it is generally estimated that 25% of the population suffer from indigestion. That is to say, regardless of exercise or not, this group of people is prone to discomfort after meals.

Some people believe that the blood of the human body is easy to concentrate in the stomach after a meal. If you start exercising at this time, the blood will flow to the skeletal muscle, affecting the blood supply to the stomach. But in fact, the food in the stomach usually takes 4 to 6 hours to be completely emptied. If there is any basis for this statement, then there are very few suitable times for sports in a day, and the daily training of athletes must be “life-threatening sports”…

In fact, for ordinary people, it is more important to be alert to exercising before meals than not exercising after meals, because fasting exercise can easily lead to hypoglycemia. In general, although it is not recommended for everyone to start exercising immediately after a meal, I hope that everyone will not be fooled by the idea that exercise after a meal is unhealthy and give up exercise. You can decide how long to start exercising after a meal based on how your body actually feels . In addition, if you often have stomach discomfort after meals, it may be a real indigestion, and it is recommended to seek help from a regular hospital.

Does eating genetically modified food alter your genes?


I don’t know if it was influenced by fictional works on the subject of “biochemical”, or because genetically modified foods carry the word “gene”. In many “fake popular science” articles, genetically modified foods are as influential as biochemical weapons. The power to alter genes. Is this possible?

the truth

Genetically modified foods may indeed contain exogenous gene fragments, but this does not mean that “exogenous genes” or the genes of genetically modified foods will affect the human body’s genes and even hereditary properties.

Genetically modified foods, like other foods, generally enter the human body through eating. Biological common sense tells us that all organisms are made up of cells, and each cell contains thousands of genes that control and maintain the identity of its species. For thousands of years, human beings have thrived, and any animal or plant food we often eat contains thousands of genes. And all genes, once entered into the human digestive system, will be decomposed into four common nucleotides in the biological world before they can be absorbed and utilized by our cells, and the genes of genetically modified food and the foreign genes carried by them are no exception.

And what everyone doesn’t know is that our bodies actually have their own defense systems. Once we find foreign DNA that shouldn’t exist, we will sensitively identify and capture it, and then eliminate it. In nature, efficient transfer of complete sequences rarely occurs. The conditions required for gene transfer are very strict. If the gene transfer can be completed by taking two bites, then the world may be full of superpowers and mutant species are running everywhere.

Thousands of years of practice have shown that there has not been a single case of the integration of genetic material transmitted through food into human genetic material. You can rest assured about the safety of regular genetically modified foods.

The darker the yolk, the better?


Many people think that the darker the egg yolk, the higher the nutritional value, is this true?

the truth

The color of the egg yolk has little to do with the nutritional value of the egg, and the color of the egg yolk is more about the market’s preference for food appearance. The vernacular is that the color of the egg yolk is “good-looking”, which is not necessarily more nutritious.

In fact, the color of the egg yolk depends on the “pigment” contained in the egg when it was formed , such as lutein. However, the nutritional value of pigments such as lutein itself is negligible and cannot be used as a basis for judging the nutritional value of eggs. Although some data show that lutein is beneficial to prevent macular degeneration, there is no definite conclusion on its actual efficacy.

Many people consider eggs with dark yolks to be chai eggs. In fact, the color of the yolk cannot be used as the basis for distinguishing whether it is a chai egg. First of all, the color of egg yolks of free-range laying hens will change depending on the food they can get. For example, in summer, if you can eat grass, insects, etc., the color of the egg yolk will be darker; in winter, when there is heavy snow, there may not be enough food. , If there is not much lutein in the food, the color of the egg yolk will be light. The second is that qualified lutein can be legally added to the feed as a colorant. Therefore, the farm can change the color of the yolk of the eggs by using the colorant-containing feed or additionally feeding food high in lutein.
