What is split power?
The theory of separate nutrition claims that for digestion of proteins, fats and carbohydrates, special digestive juices are needed, and the use of several different nutrients at once provokes rot in the stomach and a violation of metabolism.
According to this theory, adherence to a separate diet not only improves well-being, but also leads to getting rid of excess weight - without giving up your favorite foods and counting calories. FitSeven will try to figure out where the theory of separate nutrition came from, and whether it is true.
The History of Separate Nutrition
The origins of the theory of separate nutrition lie in Ayurveda, the ancient Indian doctrine of a healthy life. According to Ayurveda( and more modern teachings), there are three types of metabolism and temperament of people. Each type requires a certain supply, but some combinations of products are harmful to everyone.
The popularization of the philosophy of alternative medicine in the Western world began in the 1920s with the release of the book "The Right Combination of Food" under William Shelton. In the 1970s, a separate diet again came into fashion thanks to dietician Gary Martin.
According to Shelton's theory of separate nutrition for digestion, proteins require an acidic medium, fats and carbohydrates - alkaline. At the same time, these substances can not be digested and begin to decay. The compatibility tables of products help to avoid dangerous combinations.
An example from Shelton's book: "Put food in a pan that you eat and drink in a day, heat up to 37 degrees and maintain heat. In a few hours, the processes of fermentation and decay will begin. Imagine that something similar happens in your stomach. "
Product compatibility tables
Separate food divides products into three main categories - rich in protein( more than 15% by weight), rich in carbohydrates( more than 20% by weight), sour citrus fruits - and a number of additional ones. Products of the main categories should never be used together( 2).
Complex combinations of different types of protein( for example, meat and beans) and various types of carbohydrates( starch products with sugar) are forbidden. Watermelon, melon and milk are not compatible with any other products. Fats are allowed with carbohydrates, but not with proteins.
Criticism of a separate power supply
Scientists speak of two critical drawbacks of Shelton's theory of separate nutrition. First, the food is not digested in the stomach, but in a special section of the intestine( duodenum), where enzymes for the cleavage of various nutrients act simultaneously.
Secondly, the stomach has an aggressive acidic environment that kills microorganisms. The pot on the plate has bacteria, in the stomach - no. In order for the food to rot in the human body, a serious illness is required, and not just an unsuccessful combination of products.
Can I lose weight on a separate diet?
Numerous clinical studies do not confirm the ability of a separate diet to reduce body weight - it is impossible to lose weight, adjusting only a combination of basic macronutrients, rather than the number of foods in the diet and total caloric intake.
However, despite the fact that science has refuted the theoretical basis of separate nutrition, in practice people successfully lose weight on a separate diet. The reason is more likely that the diet requires control of the amount of food eaten and excludes typical semi-finished products.
Is it worth keeping a separate diet?
On the one hand, the scientific studies of the separate diet unequivocally showed its inefficiency for weight loss( six-week test for 54 people( 4)).On the other hand, no one denied the possible use of the philosophy of separate nutrition for general health.
The practice of meditation and observance of dietary rules of ancient Ayurveda is definitely able to improve the body and relieve pain. It is important to remember that Ayurveda requires not just knowledge of the compatibility table of products, but changes in lifestyle.
From a scientific point of view, a separate diet can not lead to a decrease in body weight without reducing the caloric content of the diet. However, behind the table of product compatibility lies the centuries-old philosophy of Ayurveda, which is really capable of affecting the body and spirit.
