No food can save you or harm you

Nowadays, when obesity and health problems are increasingly becoming the focus of people’s attention, many scientists are thinking about a problem, that is-Sugar or fat, which is worse for the human body?

In fact, in different countries, people have varying degrees of fear of fat and sugar. In the UK, fat has always been regarded as a major problem. It increases cholesterol, the risk of clogging blood vessels, and can also cause stroke and heart disease.

In the United States, people think that fat is beneficial, and sugar is a taboo. Too much sugar may lead to obesity and diabetes, so more people tend to choose a high-fat, low-sugar diet.

So what is the answer to this question? perhapsThe British BBC documentary "Who is the culprit of human health, sugar and fat"Able to answer questions for us.

The protagonist of the documentary is a pair of twins who share the same genes and are both doctors by profession. They teamed up with 7 scientists to design an experiment that lasted one month.

Nutritionists designed two completely different diet plans for the two brothers. In the next month, one of them will takeExtreme low-fat diet, The "sugar" diet; the other takesVery low carbohydrate diet, The "fat" diet.

Among them, the "sugar" diet does not contain any animal foods, but all forms of refined grain foods (bread, pasta), sugar (carbonated drinks, cakes), all fruits and various juice products are allowed.

On the other hand, the "fat" diet can only contain animal foods: meat, dairy products, eggs, and fish, but there are no obvious carbohydrates, and all vegetables and fruits are also excluded.

The two followed the extreme diet plan for a month under the supervision of scientists, and then the doctor used sophisticated equipment to record various body data in detail, including body fat ratio, cholesterol, insulin, and blood sugar data.

Two weeks after the implementation of the diet plan, the scientists took the lead in testing the effects of extreme diets on the brain.

They asked the twins to be stock traders for a day. Among them, Keith, who insists on a high-sugar diet, is in London, and Sander, who eats a high-fat menu, is in New York. The two began to try to do business on the online trading platform at the same time.

Stock trading is a very brain-consuming task. You need to memorize a lot of numbers and abbreviations, as well as learn the new language of buying and selling prices.

Tests showed that the extremely high-fat menu made Sander lack of glucose, which seemed to limit the nutrients in his brain. He was struggling with extremely high-intensity mental work and gradually fell into trouble.

AndmealInsufficient carbohydrates in food will cause a serious decline in people’s memory.If the body cannot supply enough glucose to the brain, the brain cannot function properly.

In London, the situation is quite the opposite. The high-sugar menu contains a variety of carbohydrates, from cereals, vegetables to fruits, soKeith, who sticks to the high-sugar menu, is more alert and energetic, and his memory is much better.

At the end of the day, Sander made $300, while Keith was in a good situation and made $800.

The second test is a physical fitness test. First, they have to do an hour of cycling exercise, and gradually increase the amount of exercise through variable speeds in the process.

After 45 minutes, the recorder took a blood sample, and the blood test showed how bad their condition was.Keith was burning sugar frantically. His glycemic index dropped sharply from 4.7 at the beginning to 2.7, while Sander’s condition was slightly better. His blood sugar dropped by only about 25%, from 4.8 to 3.3.

A lot of exercise made the two people hungry. In order to complete the following test, Sander followed the instructions and ate a small piece of butter (representing fat), while Keith got two small pieces of sugar. The calorie value of both was completely the same.

Afterwards, the two rode bicycles to sprint to the top of the mountain. From the beginning, the two went hand in hand. Soon, the candy-eating Keith quickly moved ahead and easily left Sander behind.

The reason is because when a person is cycling and sprinting, the body needs sugar and needs the role of carbohydrates.

Blood tests further prove this point. The sugar that Keith ate quickly entered the blood. At this moment, the blood sugar concentration in his body was extremely high, 7.1, which provided sufficient energy for the tired muscles.

At the same time, Sander’s blood sugar level is only 5.1. The butter he eats is difficult to convert into sugar quickly. Therefore, he can only rely on the muscle-consuming protein to be converted into amino acids, and then indirectly converted into sugar, which is integrated into the blood and raises blood sugar. . and soThe body without sugar can maintain exercise function, but at a price.

This shows thatPeople who eat fat have poor exercise performance and are more likely to burn muscle.

One month soon ended. After the experiment was over, the two brothers returned to the laboratory again to see what effect their respective dietary plans had on their weight and health.

Surprisingly, regardless of chronic high-sugar or chronic high-fat, both people lost weight compared to before. Among them, Keith, who ate sugar, lost 1 kilogram, half of which came from body fat, and the other half kilogram came from muscle.

The weight loss effect of Sander who eats fat is even more obvious, losing 3.5 kg of weight, of which 1.5 kg is fat and 2 kg is muscle.

Although Sander's weight has decreased more significantly, losing two kilograms of muscle weight is not good news. Because muscle is an endocrine organ that affects the body's metabolism, the loss of muscle weight means that when you are sick or old, you may have a higher chance of entering the hospital and a shorter life span.

all in all,Long-term high sugar or high fat will not cause blood lipid problems and weight loss, but high fat will reduce muscles and cause more health risks.

The results of insulin measurement have subverted traditional thinking. We usually think that sugar intake will produce insulin, but in fact,Excessive fat intake can lead to diabetes, Making the body more resistant to insulin production.

AndEating high-sugar foods will strengthen the production of insulin in the body so that the body can solve the problem of elevated blood sugar faster.

So, if a single fat and a single sugar will not cause weight gain,What makes people fatter??

In order to clarify this problem, this time, the two brothers took to the streets holding donuts, allowing passers-by to choose the kind they like.

Picture sourced from B station video

It turns out that whether in New York or London, people’s choices are surprisingly similar. Everyone prefers the most common deep-fried sugar-coated donuts. It has no chocolate or cream. It doesn’t look very good, but this is the most common one. DonutsRepresents a deadly combination of 50% sugar + 50% fat.

Like humans, mice cannot resist such a deadly combination. Obesity and drug neuroscientist Paul Kenny allowed rats to eat unlimited sugar, and found that the rats enjoyed it very much and did not get fat.

Similarly, when feeding them fat, their bodies can react quickly when they are full and stop eating.

But if they were fed cheesecake with 50% sugar + 50% fat instead, those healthy foods would be forgotten by them in an instant.

If things go on like this, mice will be addicted to continuous eating, and lazily do not like exercise.

This is becauseThe refined processed food mixed with sugar and fat will activate our body"Hedonic mechanism".This leads to overeating,This is similar to drugs. It has no nutritional value or caloric value. It is not beneficial to the human body itself, but it will excite you.

Over time,A lot of calories accumulate in the body, and weight will increase rapidly.

The existence of a large amount of processed food seriously interferes with the body's own choice of food and eating behavior.Whether it is physiological or acquired behavior, people tend to choose a combination of fat and sugar. They have a lot of calories, a lot of calories, and they are delicious, and they are fatal to anyone.

Judging from the above content, this documentary has given several very interesting conclusions, but some people criticized itThere are too few experimental samples, the differences in the physical fitness of the samples are not considered, they are not universal, and the data collection in the experimental detection process lacks rigor.

In fact, excluding these factors, the core ideas of the two doctors making the documentary are worthy of everyone’s consideration. As two doctors, they hope that there can be a simple rule or a pill to solve all obesity and health problems, but they In the end, it was impossible. becauseTo maintain a healthy body, everything depends on you!

Pictures from the Internet

In this world full of food temptations, the temptation of sugar and fat is a subject that everyone cannot escape. If you want to have healthy eating habits, you must have a high degree of self-control, give up some delicious and tempting food, and refuse to allow processed foods to become contestants in the daily diet.
