Gastrointestinal discomfort, queasiness, abdominal pain, or the unpleasant sensation of overfullness following a meal frequently stem from the incorrect pairing of food items within a single dish. In accordance with the principles of food combining—also referred to as the Hay Diet—paramount importance is placed on the deliberate selection of ingredients whose digestive properties and processing times are compatible, thereby facilitating the body’s metabolic efficiency. While contemporary perspectives on this nutritional approach vary widely among both proponents and detractors, it remains prudent to acquaint oneself with the foundational guidelines for avoiding incompatible food combinations to mitigate the likelihood of digestive disturbances.
The assumptions of the food chain theory
The nutrients that can be found in products are protein, sugars, starches, fat and acids. There is always one that decides the digestive processes. If there are more of them, these types of products are almost always heavyweight. The key to making a proper meal is to choose the products so that only one nutrient is dominant and not several. If more are present, the proportions are disrupted and there can be unpleasant gastrointestinal disorders. Other substances such as water, vitamin fibers have positive effects on the whole body, including the digestion process, and have no effect on the quality of other nutrients.
Examples of wrong combinations
Protein starch This is the most commonly occurring abnormal combination of ingredients in the digestion of these two ingredients, in which the enzymes that break down the starch are activated. However, if there is usually a feeling of overload, weight and bloating after such a meal, then it is usually due to the fact that the digestive process of starch begins in the oral cavity and the protein in the stomach. When these two constituents are digested, there is an abnormal mixing of the ingredients that breakdown the starches. If you eat a meal like this, you usually have to feel fullness, weight loss and swelling. This is because the process of digestion starts in the mouth and fat loss. This process begins when the fat loss of the fat begins after fat loss after the other ingredients can't be absorbed by the same process.
