In the 1970s, Chinese people ate carbohydrates, but the obesity rate was much lower than it is now. Why?

Obesity has always been an eternal problem that modern people worry about. How many people become obese because of eating habits and behavior habits, and actively invest in weight loss because of body problems. Repeated cycles are painful, and control carbohydrates and fats Ingestion is generally the most common practice for dieters. At this time, dieters often have questions?

In the 1970s, people could only eat carbohydrates because of the monotonous variety of food. Why are there so few fat people?

Some people may say that at that time, meat and other meat and fishes were distributed according to the amount. If you eat less meat, you will naturally not gain weight. In fact, this is not the case. Compared with fat, carbohydrates are actually easier. Let's get fat.

Why are carbs more likely to make us fat?

According to modern medical research, the human body's energy utilization is generally "balanced", that is, it will give priority to the energy that has just been absorbed. Only when there is too much energy and cannot be used, will it be converted into human body fat, and we directly If you consume carbohydrates, from the perspective of calorie and energy conversion rate, the energy value provided will be more than that of fat, and the probability of converting body fat will be greater. Eating meat often will make you gain weight.

Back to the topic, since carbs will make you fat, people in the 1970s ate it every day, why are there less fat people?

Here we have to distinguish carbohydrates. Although carbohydrates can make people gain weight, carbohydrates are also divided into types.

The first: refined carbohydrates.

Refined carbohydrates generally exist in the rice, steamed bread or noodles that we usually eat. The reason why it is called refined carbohydrates is because the raw materials of these foods are degerminated and peeled layer by layer, and only rice or wheat is left. There are better-tasting substances such as germ and endosperm in the body. The sugar in these substances can allow the body to absorb more quickly, obtain energy, and naturally make you fatter.

The second: crude carbohydrates.

Crude carbohydrates are generally sweet potatoes, corn , etc. This type of carbohydrates not only has a lower energy holding rate than refined carbohydrates, but also because there are no more processing steps, the rich dietary fiber can help gastrointestinal motility, thereby further increasing energy. consumption. Naturally it won't make you fatter.

The answer is already obvious. How could people in the 1970s eat fine rice and noodles like they are now? The carbohydrates that people ate at that time were often crude carbohydrates such as sweet potatoes and corn. Speaking of "coarse grains", the natural obesity rate will not be higher than it is now.

Seeing that this kind of crude carbohydrates can reduce energy intake, are you thinking of losing weight and can't wait to improve your diet? Don't worry, although " coarse grains" are good, you should pay attention to some things when eating them .

Here are some notes:

①Can not replace the staple food . Although coarse grains are healthy, they cannot provide energy compared with refined grains. If they are eaten instead of staple food, it will cause symptoms such as malnutrition.

② Those with bad stomach should eat less. Although whole grains are rich in dietary fiber, dietary fiber promotes gastrointestinal motility through its indigestible properties. If people with bad stomach eat too much, it is easy to cause more burden on the stomach.

③ The elderly should eat less . Compared with young people, the body's conversion rate of energy is lower than that of young people, so they need to take in more energy. If the elderly do not have obvious symptoms such as diabetes and high blood pressure, it is better to eat less whole grains.

It can be seen that although people in the 1970s ate carbohydrates every day, but the obesity rate was low, there are still reasons to follow, and modern people should not blindly follow. Eating coarse grains and refined grains alternately, and frequently changing the type of staple food, is the best way to use carbohydrates and have a healthy body. I hope everyone will keep this in mind.
