Separate power supply system developed by the American doctor Herbert Shelton — author of the famous book "The right combination of foods. " Shelton was referring to the study Russian physiologist Ivan Pavlov.
Russian scientist in the late XIX century, argued that the different types of food (meat, bread and milk) are digested in different parts of the gastrointestinal tract and using a completely different digestive enzymes. The specificity of the digestive juices allocated to each particular type of food, so different in character that Paul called them "milky sap", "bread juice" and "meat juice".
Herbert Shelton believed that the ordinary nutrition causes that incongruous between the products are not normally absorbed by the body. According to Shelton, the conditions necessary for the digestion of different types of products are different: to break down proteins requires an acidic environment for carbohydrates — alkaline. If food simultaneously and contains a large amount of proteins and carbohydrates, it is natural that something of them will be acquired worse. For example, eaten on an empty stomach apple leaves him after only 15-20 minutes. If you eat it after the meat, apple linger in the stomach and cause fermentation and putrefaction. As a result, both products will go to the lower digestive tract ill-treated. This leads not only to deposition of fat, but also to an increased load on the pancreas and undigested food accumulating in the colon can cause a variety of diseases.
The modern view of the system Shelton
The system of separate food Herbert Shelton is still very popular around the world, although many of its approval by modern science disproved. For example, Shelton was sure that people suffer from allergies, and not from undigested food. That is, in Shelton, allergy — it is nothing like protein poisoning. Of course, has long been proven that allergy — is immune disease, and the order of the meal is in no way connected.
Modern nutritionists are not taken seriously and one dogma Shelton: for the digestion of carbohydrates and fats needed alkaline environment, and for the protein — sour. It has been proved that in fact the process of digestion more difficult, it involves various enzyme systems — saliva, gastric and intestinal juices, bile, pancreatic secretion. Accordingly, various components of the food digest in the digestive tract is divided in both time and space. That is, in the digestion of an intact organism different types of food takes place in parallel, they do not interfere with each other.
Here are a few comments of experts
Head of the Department of Metabolic Diseases, Institute of Nutrition, Ministry of Health of Russia, MD UP Popov notes:
"Separate food is not curative. Physiological rationale for him there. For centuries, the evolution of the human digestive tract is prepared to mixed feeding. Also in nature is very little monoproduct. Is that the salt and sugar. All other — and a combination of proteins and fats, and acid … . "
Just consider and Olga Zaykina, a leading researcher at the Institute of Immunology, Ministry of Health of Russia:
"Not quite right to share in the food protein and carbohydrate. Most of the food — and the animals and plants — there are proteins, fats and carbohydrates, and they can not be split. Correct break food product groups and their compatibility. "
But we can not say that modern medicine — a categorical opponent of the "method of Shelton." The principles of food combining, "soft", gentle product handling, plenty of fruits and vegetables do not cause any objections nutritionists. In addition, "sharing" products to compatible and incompatible, the follower of Dr. Shelton comes to the table 7-9 times per day, and the fractional nutrition — Ideal physicians.
