Zero fat is not equal to health+zero energy
Zero fat is not equal to zero energy.
As we know, the nutrients needed to maintain life and health include carbohydrates, lipids, protein, minerals, vitamins and water, among which carbohydrates, fats and protein can all generate energy through internal oxidation. These three nutrients are called "productivity nutrients", and the energy our body needs comes from these three nutrients. 1g carbohydrate oxidizes in vivo to generate 4 kcal energy, 1g fat generates 9 kcal energy, and 1g protein generates 4 kcal energy. In addition, the oxidation of alcohol in the body will also produce energy, and 1 g of alcohol will produce 7 kilocalories of energy.
The nutrients we need come from all kinds of food, and only one of the three energy-supplying nutrients in food can provide us with energy. Therefore, if a food contains no or less of these three nutrients, it contains no or less energy. So foods marked with 0 fat are not equal to 0 calories. If it contains carbohydrates, it contains energy and added sugar and fat.
The energy source should be mainly plant food. The suitable dietary energy composition recommended by WHO is: carbohydrate 55% ~ 65%, fat 20% ~ 30%, protein 1 1% ~ 15%.
Fat is certainly not equal to health.
There are more than 40 kinds of nutrients needed to maintain life and health, so human beings need a variety of foods. All kinds of food have their own nutritional advantages, and there is no difference between good and bad food. How to choose the type and quantity of food to match the diet determines whether the diet is reasonable or not. Therefore, the core of a healthy diet should be reasonable collocation. Fat is also one of the nutrients needed by human body, which has many physiological functions besides energy supply. Some unsaturated fatty acids are good for health. It is just a food that people with excess energy and abnormal blood lipids should not choose.
0 Fat only indicates the amount of fat in the beverage, and it cannot be equated with health. The influence of beverage on health depends on whether the beverage contains other ingredients such as energy. Many sugary drinks contain no fat, but added sugar and a lot of energy.
As a drink, the gimmick of "zero fat" actually doesn't make much sense. The health hazards caused by beverages, such as increasing the risk of obesity and diabetes, are mainly due to the fact that beverages contain more sugar and higher energy. Even if it is "zero fat", it may increase energy due to the addition of sucrose, fructose or glucose, and the health hazard of drinking beverages for a long time still exists.
