First you need to know what the concept of carbohydrates providing 77% of total energy intake is.

Chinese people's carbohydrate energy supply is about 50%, 77% means that the person can't eat much meat every day, and seldom eat oil, mainly is the staple food stuff, such as rice and noodles, mixed grains, potatoes.

Such a person, therefore, should live in a very poor place, such as a barren mountainous area, and it would be strange for a person to live long in such a place.

Unbalanced nutrition is only one of the factors contributing to the high "mortality rate", but more importantly, it may be due to the low level of medical care and poor living conditions.

In addition, the study used data from an unknown source; at least the Chinese data would have been from a decade or two ago.

Additional Notes:

1. Indicators of health, disease, mortality, etc. are determined by a combination of many factors, and it's not as simple as A causing B. For example, people with high carbohydrate intake are likely to have lower cancer rates yet. (Because they died early before they could get cancer). So correlation ≠ causation, which is important to remember.

2. The latest research is often also less reliable, even if it is published in top international journals such as the Lancet, Science and Nature. The more cutting-edge and novel the research, the more uncertainty there may be. Older studies are more reliable because they have been continually verified by many scientists.

3. The current dietary guidelines of various countries are similar and have been formulated after synthesizing the results of countless scientific studies. Therefore, a paper that talks about subverting the dietary guidelines is simply ridiculous. In science, incremental discoveries are the majority, and subversive discoveries can apply for the Nobel Prize.

I didn't see the original Lancet article, but the introduction gives a general idea of what the full article is saying. To put it bluntly, if your diet is a lot of refined rice and white flour, and other foods do not make up a large proportion of your diet then it is possible to have a higher incidence of cardiovascular disease. So today I'm going to talk to you about how to eat healthy.

A healthy diet is an important weapon in your arsenal to stay healthy while fighting off disease. So how can you eat healthy? Many people have been eating all their lives and have eaten everything that tastes good, but don't really know how to eat healthy. Actually eating healthy is not as hard as you think!

Get healthy nutrients from a variety of foods

You may be eating tons of food, but your body may not be getting the healthy nutrients that are most necessary. Nutrient-dense foods are rich in minerals, proteins, vitamins and other nutrients, but low in calories. They can help you control your weight, cholesterol and blood pressure.

Eating nutritiously requires the following characteristics:

- A variety of fruits and vegetables.

- Whole grains.

- Low-fat dairy products.

- Skinless chicken and fish

- Nuts and legumes

Limit saturated fats, trans fats, sodium, red meat, candy and sugar sweetened beverages.

Eat fewer foods that are mono-nutritious.

It is recommended to limit foods and beverages that are nutritionally monotonous or even cause adverse effects. Also limit the intake of saturated fats, trans fats and sodium. Examples include high-sugar drinks, high-fat diets, high-salt diets, Western fast food, and so on.

As you make your daily food choices, follow these suggestions for your eating patterns

- Eat a variety of fresh vegetables and fruits and consider replacing high-calorie foods with fruits and vegetables.

- Choose fiber-rich whole grain staples.

- Choose poultry and fish without skin and cook them in a healthy way without adding saturated and trans fats.

- Eat fish at least twice a week, especially fish with omega-3 fatty acids (e.g. salmon, trout and herring).

- Choose fat-free (skim) and low-fat (1%) dairy products.

- Avoid foods containing partially hydrogenated vegetable oils to reduce trans fats in your diet.

- Limiting saturated and trans fats reduces saturated fat to no more than 5 to 6 percent of total calories. For someone eating 2,000 calories a day, that's about 13 grams of saturated fat.

- Reduce beverages and foods with added sugar.

- Choose foods with less sodium and prepare foods with almost no salt. To lower blood pressure, eat no more than 2,400 milligrams of sodium (6 grams of salt) per day. Reducing your daily intake to 1,500 milligrams (4 grams of sodium) is desirable because it can lower your blood pressure even further. If these goals cannot be met now, even a reduction of 1,000 milligrams of sodium intake per day (2.5 grams of salt) can be beneficial to blood pressure.

- If you drink, drink in moderation. No more than one or two white wines, no more than 250 ml of beer, and no more than 150 ml of red wine.

Although different from the customary perception, but it does have a scientific basis. You have to distinguish, people say is in a single contrasting conditions of comparison, starting from the fertilized egg, the number of cell division in a person's life is limited, the amount of food is also much the same, the more you eat the faster you die, the more staple food, the faster you die.

From the perspective of traditional Chinese medicine, all food is the essence of water and grain, according to the "Emperor's Classic of Internal Medicine" said: food gas into the stomach, scattered essence in the liver, obscene gas in the tendons. Food gas into the stomach, the turbid gas to the heart, obscene essence in the veins; pulse gas flow through the meridians, the meridian gas returned to the lungs, lungs towards the hundred veins, lose the essence of the skin; hair veins together with the essence of the line gas in the internal organs; internal organs of the spirit of the Ming, to stay in the four viscera, the gas returned to the weights and balances; the weights and balances to the level of the air into the inches of the mouth to determine the death of the life and death. Drinking into the stomach, overflow essence, up to the spleen; spleen dispersal of essence, up to the lungs; through the waterway, down to the bladder; four cloth of water, the five meridians in parallel, together with the four seasons of the five organs of the yin and yang, premise that often.

Water and grain essence into the body need to be coordinated in all parts of the body for transportation, take the essence, moisten the meridians, supply energy, discard the dross, in various forms of discharge.

The main food, in a sense, is the main source of energy in the body's water and grain essence, and relatively more dregs, so the main food can not be eaten, but in order not to increase the burden on all parts of the body's organs, eat less and more healthy, eat more food that is good for the human body more healthy.

I wish to express my personal opinion for information purposes only.

Staple food ~ five grains for nourishment, thousands of years of inheritance is the main body of life support, benevolent life, broad-minded body broad, the benevolence of the way of heaven and earth, benevolence of the less struggle less anger less grudges more joy,, broad-minded less sorrow less worry less worry less stress, that is, the goodness of the belly is the basis of longevity [a flash of light]

A few years ago at home, my partner every day to see the health of television programs, there is a station almost every day to talk about vegetarianism, beneficial to longevity and reduce disease and fight environmental protection and ecology, now people get two cancers, vascular disease is more than one reason is because of eating fat meat more results. However, one day during dinner, the central two stations have a longevity talk show, Beijing, several longevity of the elderly mostly like to eat meat, one of the 103-year-old woman said: like to eat fat meat, every day to eat some fat meat. And the old lady is quite healthy.

In fact, people will always die, and bricklayers can't discover the immortality drug. So, I think it's good to be able to talk about 60 years old. Living old is purely suffering rather than enjoying the blessings.

Of course, I hope that each person will live to his or her own satisfaction, but then, that depends on God's will.

Science and technology popularization prompts people to develop the habit of rational thinking and rational handling of affairs - Kaiten Gathering Knowledge.

The questioner is providing a statistical analysis report, which can also be referred to as a big data analysis report.

We do not want to evaluate this report, we take this opportunity to popularize how to look at the statistical analysis report.

A few typical concepts of statistical analysis.

1. Sample size, sample size, sample characteristics

1.1 Sample size: Sample size is the number of units contained in a sample.

1.2 Sample size: the actual number of samples for a given sample size. Related to sample size and sampling method.

1.3 Sample Characteristics: the sum of sample indicators and their characteristics that can be studied/described at the time of sample analysis. It is also, ultimately, the matter of statistical analysis to be distilled.

1.4 Correlation: Statistical analysis refers to the consistency of the trend of change between two characteristics (variables), if the trend of change of the two variables is consistent, it becomes correlation, otherwise it is not correlated.

2. How to read statistical analysis reports

2.1. Look at the sample size

The sample size should cover the essential traits/characteristics of the study population.

The size of the sample size is directly related to the accuracy of the inferred estimates, i.e., the larger the sample size, the smaller the representativeness error of the statistical estimates, and conversely, the smaller the sample size, the larger the estimation error, given the overall situation.

A crowd of 40,000 or so is hardly representative of a large group of 1.4 billion.

2.2 Sample size

The more reasonable the sample grouping and the larger the sample size, the more valid the statistical results will be for a certain sample size.

2.3 Sample characteristics

The more clearly the sample is characterized, the more reliable the findings are.

2.4 Relevance

The larger the correlation coefficient, the greater the correlation!

Understanding the above concepts then gives you an opinion on the results of many statistical analysis reports.

This study is not comprehensively representative, not popular, and as people have said, the research group is manual laborers of moderate to high intensity.

This group belongs to the lower middle class in society, income determines the quality of life, the usual diet is mainly vegetarian, meat as a supplement, but it is not a reason to eat more staple food will die faster, and nowadays the life expectancy of rural people is generally higher than that of urban people. So talking about this issue, the main thing is a dietary balance, this latest study, not representative.

The composition of life itself is extremely complex, and the current life sciences have not fully researched the human body. Human life expectancy is affected by genetic inheritance and acquired environmental influences, in which the impact of eating on the human body is indeed very large, but not up to eat more staple food will die faster that kind of conditions, so that does not have a broad representation.

But this study is not wrong. Because of the complexity of the human body, the wide distribution of races, and regionality, food culture can reflect the characteristics of death, but all abide by the same principle: the body can be digested and absorbed on the line. In other words, you can eat whatever you want, as long as your body can accept it.

So why is it possible to come to this research conclusion? It's no more than two things: one, malnutrition; and two, overnutrition.

Lancet mentioned above this part of the population, is a typical malnutrition. This part of the workers, do physical labor, its consumption of energy is greater than the absorption of nutrients, a long time overload work, it will make the body's organs function rapid aging, directly affecting the life expectancy. And for the over-nutrition, is also the same reason. Eat too much too good big fine, intake of protein, too much fat, the same will accelerate the consumption of human organs, affecting life expectancy. Life, die prematurely also includes a part of the rich.

That's why people who have a balanced and rational diet, as well as a happy body and mind, and who have no desires and wants, tend to live longer. The so-called high-end life essence, in fact, the pursuit of more joy in life, rather than the life of luxury and exquisite. The idea of human life comes from the primitive society, and will eventually return to the primitive society. The core of the pursuit of high-quality life is: simple, happy!

Have you ever thought about the question of why women have to live longer than men on average? It may be because women eat less than men.

I'm just a regular guy, not an expert, just not very well and have a little bit of knowledge on the subject.

"Eating more staple foods kills you faster" is not the latest research.For example, in the 1960s, scientists experimented with mice by comparing calorie restriction and found that the average life expectancy of the calorie-restricted group of mice was 40% longer, and in a region where there was a large reduction in wheat production for a long period of time because of a natural disaster, the statistics unexpectedly found that the average life expectancy of the people had increased by 6 years. The benefits of calorie restriction have been demonstrated in human experiments all over the world.

The BBC documentary Light Fasting encourages people to restrict their calorie intake for two days out of the week to manage their weight and high blood sugar problems, and has received tons of good feedback.

The current mainstream view is that humans should eat a balanced diet, that is, you should eat a little bit of everything, fruits and vegetables of all colors, and all parts of the plant, roots, stems and leaves should be taken care of in the best possible way. This seems to be a relatively general and conservative viewpoint that everyone can easily agree with.

Perlmutter, author of The Grain Brain, is a leading expert on neurodegenerative diseases, and his book expresses a very different view from the mainstream, citing a large number of experimental reports, the author believes that the human body does not need carbohydrates, carbohydrates are harmful to the human body, especially wheat containing gluten is the main culprit of Alzheimer's disease.

Science is the development of the truth is also gradually discovered, the views of experts are always inconsistent, this contradiction is also to promote the power of scientific progress, the previous mainstream view also think that the food in the fiber is useless, but now it is considered essential. For the public, the new point of view is not easy to accept, but more understanding does not hurt, understand more, through independent thinking to reach their own conclusions is certainly stronger than a hearsay ......

2018 Lancet's latest post on how eating more or fewer staples can affect life expectancy, shaking up traditional notions of health

In the past two days, the nutrition sections of the world's major media outlets and networks have been so busy, they've been exploding with the results of a study.

The reason for this is that on August 17th, The Lancet, a leading international medical journal, published a research paper on carbohydrates and mortality.

This paper concludes that mortality reaches its nadir at a carbohydrate energy supply ratio of 50-55%. And those above or below this mark had varying increases in mortality. Those with the lowest carbohydrate intake had the highest mortality rates. Those on low-carb diets who also consume a lot of animal protein and fat at the same time are more likely to die early. However, if the same low-carbohydrate dieter favors a vegetarian diet with a predominance of plant proteins and fats, the probability of early death is low.

Are you dizzy? It's never been Ohe's style to be so tongue-in-cheek.

Big River gives you the most grounded translation of it:

1. Eating too much or too little of staple food (rice and noodles) affects life expectancy; the less you eat, the faster you die.

2. If you replace your staple food with animal protein (chicken, duck, fish and meat), you will live a shorter life.

3. Life expectancy will be extended if vegetable proteins (beans, peanuts, nuts) are substituted for staple foods.

4. Eating too many carbohydrates, such as fruit, may affect health and longevity.

Certainly not as rigorous as a dissertation, so please appreciate the spirit.

The authority of the Lancet is unquestionable; it is the jewel of the medical profession, and those who are able to publish are leaders in their field.

This is not the first time the Lancet has messed up; in August 2017, the Lancet published three articles, the original of which you can search for. Many media outlets interpreted them as:

1. Eating staple foods such as rice, flour and sugar (the main source of carbohydrates) may kill you sooner.

2. eating more good fats and eating oils may allow you to live longer.

3. Eating foods rich in saturated fats, such as fatty meats and coconut oil, can reduce the risk of stroke.

4. There is no relationship between oil consumption and heart disease, and no amount of oil will raise the risk of heart disease.

How, enough subversion, right? I believe that many medical health experts are crazy inside, more of those who listen to watch the CCTV health channel every day moncler outlet store is bewildered, is it hard to popularize those health theories in the past, overnight are wrong? In the end, which one is right, how do we eat in the future?

Please listen to the next explanation.

It's not easy to code, so please feel free to reprint it.
