The health philosophy that we are exposed to on a daily basis is to take 10,000 steps a day and "eat grass" (more than fruits, vegetables, salads...). ) is the most common.
These two concepts are accepted by most people and have also attracted the pursuit of capital. The sports bracelets launched by major mobile phone manufacturers and technology companies have long become a new revenue growth point; and the most popular salad in healthy eating, in 2015, there were fewer than 50 salad shops in Shanghai, and by the end of 2016, it had grown to 300-400.
However, for the 10,000 steps a day and "eating grass", we almost instinctively believe that this is health, and we don't seem to have seriously considered the scientific basis behind it. The BBC documentaries The Truth About Fitness and Clean Eating Dirty Truth have upended our perceptions.
Ten thousand steps a day is just a marketing scam
Walking 10,000 steps a day for health seems to have become a kind of "common sense". The BBC told us in the documentary "The Truth About Fitness" that "10,000 steps a day" is actually a marketing scam.
In the mid-1960s, during the Tokyo Olympic Games, Japan invented the first pedometer, and Manpo-Meter played the slogan of "10,000 steps a day" for the first time. What is the scientific basis? Not really.
At that time, the pedometer manufacturer roughly counted the number of steps that Japanese people walked every day, about 3500-5000 steps, and the idea of the pedometer company at that time was to multiply the average upper limit (5000) by 2 to achieve the role of fitness.
This proposal was approved by all the members of the marketing department. As a result, the slogan "10,000 steps a day" has been popularized and has become a health concept that people believe in.
Just eating vegetarians doesn't make us healthier
Eating only vegetarian food is a "belief" of many people who advocate health, and the "pursuit" of vegetarian food in China was initially influenced by the popular European and American dietary concepts. In the documentary Clean Diet, Dirty Truth, Gilles Chiu, PhD in Molecular Genetics at the University of Cambridge, devotes himself to exploring the "truth" of clean diet.
Clean Eating is a "net red" diet concept in Europe and the United States, which refers to the intake of a large amount of unprocessed natural agricultural products to purify the body through ingredients. The "vegan diet", the "gluten-free diet", and the "alkaline diet" (the author of this theory in the documentary was arrested last year) are all part of the purification diet.
Dr. Qiu found Ella, an internet celebrity blogger who rejected animal diets, and found that Ella actually did not understand the scientific theory of diet, and her theory was derived from a book called "Life-Saving Diet".
Dr. Qiu then found the author of the book, Professor Campbell, who gave the conclusion that meat intake is related to the growth rate of cancer and heart disease, but in the experiment, cholesterol was used instead of protein content, ignoring factors such as human genetics and weight. In the end, Campbell himself admitted that this theory was not supported by sufficient scientific evidence.
The gluten-free diet in a clean diet is to not eat foods that contain wheat, including bread, beer... This diet was first used to treat celiac disease patients, but with the blessing of Hollywood stars and athletes, it became a weight loss label.
Dr. Chiu approached Bill Davis, an advocate for not eating grains. Davis believes that wheat pure protein contained in wheat can allow foreign substances to enter the body, which may cause an immune attack on the body, and said that Professor Fasano, the world's top expert on celiac disease, can support his theory.
Dr. Qiu asked him, "In a way, is eating grain harmful to all of humanity?" His answer was YES. When Dr. Qiu approached Professor Fasano, the professor disagreed with Davis.
According to Professor Fasano's research, relying solely on gluten cannot cause any problems. Gluten is harmful when problems arise with genetic inherited infections, leaky gut, problematic immune system, symptoms of intestinal flora imbalance.
Davis "upgraded" the research theory to be harmful to the entire human race, so easily removed gluten food from people's diets, and many stars once regarded it as "truth".
Is it really healthy, or is it infinitely amplifying panic?
Australian supermodel Bridget Malcolm is a victim of the "clean diet", according to media reports, she posted a blog last year about her blind pursuit of clean diet caused by physical deformities, apologizing to the majority of netizens for spreading this unhealthy concept of eating.
Whether it is 10,000 steps a day, or the rejection of animal and wheat food, in the final analysis, either there is no scientific theory as a support, or for the uncertain theory, because the verification standard is high, directly remove this food.
And these health concepts without theoretical support, using people's panic about health, came a precise "brainwashing", crazy marketing, so that the truth of health is silent.
Ten thousand steps a day is not suitable for everyone, in "The Truth of Health", two groups of people were found to do experiments, and the group that took time and effort to walk 10,000 steps was far less intense than the 30 minutes of brisk walking while talking, because they engaged in more efficient medium-intensity exercise. Not everyone is suitable for taking 10,000 steps that much.
Animal food is also not a "flood beast". According to research published in 2017 in the journal The Lancet, fat intake may reduce overall mortality. The Dietary Guidelines for Chinese Residents (2016) recommend that an average of more than 12 foods should be ingested per day, specific to a meal that should contain at least 100g of grain potatoes, 150g-200g of vegetables, 100g of fish, eggs and beans, and 50g of fruits.
