Research of products on the content of starch. Foods high in starch
Starch is found in many plantproducts that are regularly consumed by people for food. It began to receive in ancient Greece and Rome. 80% of human carbohydrates are products with starch content. For an organism such quantity of this component is not useful. This component is easier to disintegrate when ingested in the digestive tract, if used in its raw natural form. The presence of starch can also be determined at home.
Processing of starch by the body
Starch belongs to the group of polysaccharides,natural high-molecular carbohydrates. A huge number of plants contain this combined sugar in their cells. It is in buckwheat, carrots, potatoes, plant stalks, fruits and leaves. It is necessary for the normal operation of the human body.
The study of products for starch content showed a large amount in such frequently used ingredients as potatoes, wheat, corn, buckwheat, rice, beans, etc.
Disintegration of raw products with starch contentbegins immediately after entering the mouth under the influence of saliva. It turns into maltose. After it enters the intestine, it is hydrolyzed into monosaccharides. They, in turn, penetrate through the walls of the intestine and become phosphates, which enter the blood. Eventually they become glucose. Starch content in foods is an important indicator of the chemical composition for those who diet and exercise.
Boiled starch has a very negativeimpact on the person. Scientists studying starch, declare the inability of its molecules to dissolve in water, alcohol and ether. This product has the property of clogging the blood. When exposed to hot water, the starch swells. The same result is obtained if it is inside. It requires fluid, takes it from the body. Such a paste clogs the 12-colon and the small intestine.
Many doctors argue that excessive consumption of foods with a high content of starch causes a risk of cancer. Women are the most dangerous to abuse pastries.
Proper use of starchy foods
Eliminate completely from the diet products,containing starch, is impossible. They are necessary in the body to replenish it with energy. You just need to control the amount of their use. For normal assimilation of products with starch content should not be more than 20% of all entering the body.
The study of products for starch content shows that, if certain requirements are met, it is possible to protect yourself from negative effects as much as possible.
The basic rules for the safe use of starch-containing food:
- the substance is poorly digested with other products;
- the best combination: starch + salad from raw vegetables;
- it is easier to digest when there is sufficient intake of B vitamins into the body;
- products with element content are not recommended to be heat treated.
Use of starch in the food industry
Study of products for starch contentindicates their widespread use in food production. The substance is subjected to high temperature processing. This starch is called modified. He will fill the body with extra calories. This means that such products are difficult to digest and very difficult to remove.
Products containing starch: Liqueur sweets, confectionary cream, glaze, fillers, semi-finished products, yoghurts, desserts, canned food, ice cream. It also includes frozen vegetables, meat, fish, fat substitutes, drinks, soups, semi-finished products, nuts in glazes and others.
Foods high in starch
As we have already understood, there are many of them. And sometimes the content of starch in products is very high. The table below shows those titles that contain the largest number of titles. Vegetables with a high content of starch are recommended to be used with the addition of sour cream, butter or cream. These include: beets, radishes, sweet potatoes, potatoes and Jerusalem artichokes.Share of starch in products
|Product name||Content in%|
|Flour from corn||65|
|Noodles from wholemeal||64|
|Dishes from oats||61|
|Whole-wheat flour biscuits||58|
|Bread from rye flour||45|
|Products from puff pastry||37|
|Puree from potatoes||11|
Vegetable food with low starch content
The smallest content of this element in pepper,cabbage and fruit. We continue to consider the starch content of the products. The table has united those names in which there is the least amount. So, which products are the least dangerous in this case?Products with a minimum content of starch
Product testing for starch
At home, you can conduct research on starch content. For this, iodine or Lugol's solution is usually used.It is necessary to put a few drops on a piecebanana, add to the porridge, yogurt, mayonnaise or any other food. The more starch in the object under test, the darker the stain becomes. Such a small experiment will expand knowledge about the daily diet and help to understand the quality of food. In this way, you can check the same products from different manufacturers and choose the best quality. This method is often used by the hostess when checking milk, cottage cheese and honey. In these products, there should not be any starch.
Products must be selected individually. Everything depends on the needs and possibilities of their assimilation. Observing a special diet, it is necessary to minimize the duration of diets without carbohydrates. Their absence in the body leads to stress. Therefore, plant foods must be present in the diet, as well as carbohydrate.
