A high-residual diet, also known as a high-fiber diet, contains more dietary fiber than a traditional diet. This is a therapeutic diet, recommended among others in the fight against constipation and in the prevention of intestinal diseases, including irritable bowel syndrome and colorectal cancer. In addition, a high-residual diet prevents the development of atherosclerosis, diabetes and obesity. What are the principles of a high fiber diet?
A high-residual diet, or high-fiber diet, contains more than the traditional diet of the number of plant polysaccharides not digested in the human digestive tract (fiber, hemicellulose, lignin, pectin, gum). According to the recommendations of doctors and nutritionists, the basic diet of a healthy person should contain 30-40 grams of polysaccharides. A high-residual diet assumes that you need to provide your body with 50-70 grams of these substances every day.
Rich residual diet – rules. What is a high fiber diet?
When composing a menu, you should, first of all, choose products that contain a higher content of dietary fiber. These include thick groats, dark bread, brown rice, as well as dried fruits (especially dried plums). It is recommended that you never cook groats or pasta (as well as vegetables) until semi-hard. The cooking process causes the loss of at least some of the valuable ingredients they contain, including fiber.
A rich source of fiber is also raw fruits and vegetables, as well as legumes, which, due to the extremely high content of polysaccharides and low calorific value, should be consumed in an amount of about 1 kg per day.
To the products on the traditional menu, add those rich in fiber, e.g. oatmeal can be combined with milk, yoghurt or salads. In turn, wheat bran is an ideal addition to potatoes and even juices, both fruit and vegetable.
High-fat products should be eliminated from the menu. Only from time to time, you can afford small amounts of low-fat products. For example, a slice of cheese or cottage cheese can be combined with wholemeal or rye bread. Do not eat too many eggs. Any fried or roasted fat dishes are also forbidden. Lean meat, recommended in a high-residual diet, can be cooked, stewed or fried without fat.
In addition, when using a high fiber diet, you should give up sugar and sweets, as well as highly processed products, because they do not have any residual ingredients and are very caloric.
Drinking intensive tea infusion is also discouraged. It’s best to replace it with herbal infusions that positively affect the digestive process.
A high-residual diet should be introduced gradually so that the digestive tract can get used to more and more fiber. This way you will avoid side effects such as bloating, colic or diarrhoea.
High-residual diet – in the prevention and treatment of which diseases a high-fiber diet is used?
A high-residual diet is used in the prevention of irritable bowel syndrome, diverticular disease and colorectal cancer because polysaccharides absorb carcinogens formed in the intestine from the breakdown of bile acids and further accelerate their excretion. A high-fibre diet prevents the development of atherosclerosis, cholelithiasis, diabetes and obesity, as fiber reduces cholesterol, triglycerides and glucose. It is also a proven method for constipation, especially habitual ones because plant polysaccharides increase the amount of water in the intestinal contents.
Rich residual diet – who can’t use it?
Residual rich diet cannot be used primarily by people suffering from inflammation of the stomach, pancreas, bile ducts and intestines, as well as people with gastrointestinal catarrh and gastric or duodenal ulcer.
The use of a residual rich diet in children is controversial. Some specialists believe that fiber limits the absorption of vitamins, which is why in the case of children and adolescents, where vitamins and other nutrients play a key role in their development, the introduction of large amounts of fiber should be well thought out and preferably preceded by medical consultation. The same should be done for older people.
