What cereals can be eaten with type 2 diabetes?
In type 2 diabetes, cereals with a glycemic index of no more than 69 units are allowed. Due to the high content of vegetable fiber, cereals are more difficult to digest in the gastrointestinal tract. A long process of digestion leads to slow absorption of carbohydrates.
The complex chain of polysaccharides, which makes up to 80% of the seed structure, is destroyed by hydrochloric acid and active enzymes within 2 hours. During this period, the plasma concentration of glucose in the blood gradually increases, the hypoglycemic drug has time to act, and insulin is released.
Porridge properties
In the composition of cereals, there are no fast carbohydrates, which are easily broken down to glucose under the action of hydrochloric acid and contribute to a sharp increase in the concentration of sugar in the body. Most of the chemical structure of various cereals is occupied by coarse fiber. Dietary fiber is a complex carbohydrate structure that is digested 3 times slower than sugary foods.
Due to the high content of vegetable fiber, glucose is absorbed within 1.5-2 hours, during which there is a smooth release of insulin.
In addition to dietary fiber, cereals contain a number of vitamins and minerals necessary to maintain metabolism against the background of type 2 diabetes. Cereal crops have the following effect on the body:
- accelerate intracellular metabolism;
- strengthen the immune system due to the inclusion of ascorbic acid;
- increase the functional activity of the nervous system, improve the transmission of nerve impulses;
- stabilize the digestive system;
- cleanse the gastrointestinal tract from slag masses and toxins;
- reduce the level of bad cholesterol in the blood plasma, reducing the likelihood of atherosclerotic plaques on the walls of blood vessels;
- support the work of the hematopoietic and cardiovascular systems.
Despite the high calorie content, cereals are allowed for use in non-insulin dependent diabetes. This is due to the low or medium glycemic index (GI) of cereal products. Their structure is represented by a long chain of polysaccharides, which is difficult to destroy.
List of permitted cereals
With type 2 diabetes, you can only eat cereals with a low or medium GI up to 69 units:
- buckwheat;
- oats;
- corn;
- millet;
- wheat;
- pearl barley;
- flaxseed;
- legumes: beans and peas;
- barley grits.
If the glycemic index of a cereal product is higher than this indicator, it must be completely excluded from the diet. The lower the GI of a cereal crop, the longer the process of digestion and absorption of nutrient compounds will take.
As a result, diabetics should eat more cereals with a GI of less than 39 units.
Buckwheat
The GI of buckwheat is 50 units. It consists of vegetable proteins, the structure of which is a chain of 18 essential and non-essential amino acids. Buckwheat is rich in the following nutritional compounds:
- magnesium;
- phosphorus;
- iron;
- folic acid;
- group B vitamins.
Due to the high content of flavonoids Buckwheat stabilizes the concentration of sugar in the blood plasma and maintains it within the normal range. Organic acids in the composition of grain crops have an antitumor effect and accelerate metabolism. At the same time, they are potential allergens and can cause inflammation of the face, tongue and throat in immunocompromised diabetics.
In non-insulin dependent diabetes it is recommended to use sprouted buckwheat. Green cereals do not undergo long-term cleaning, so it retains its natural chemical composition. The amount of vitamins and minerals in it is 2 times higher.
Legumes
In diabetes, it is recommended to eat only peas and beans. They differ in the minimum content of carbohydrate compounds. At the same time, legumes can replenish vitamins and minerals in the body. Wherein the risk of becoming overweight does not increase. In peas and beans, which are prepared by mild heat treatment (boiled or baked), the GI gradually decreases. Under the action of high temperature, the main bonds between protein and carbohydrate chains are destroyed.
corn
The GI of corn is 40 units. 150-200 g of a grain product provides a diabetic patient with 25% of the daily requirement of vitamin E and beta-carotenes, from which vitamin A will subsequently be formed. At the same time, corn grits should not be abused, as it is a high-calorie food. A large amount of starch and polysaccharides contained in a grain crop can lead to obesity.
To cleanse the body of slag masses and toxic substances, it is necessary to take corn porridge once a week. Vegetable proteins in the composition of the product are practically not absorbed, so cereals are not used to normalize protein metabolism. The active substances contained in grains prevent the absorption of fats and fatty acids.
Thanks to this effect, corn normalizes lipid metabolism, promotes the removal of bad cholesterol and stabilizes blood sugar levels.
oatmeal
The glycemic index of oatmeal is 49 units. In type 2 diabetes, it is recommended to consume oatmeal porridge daily. Despite the average GI, cereals are not high in calories. 200 g of the product provides the body with 25% of the daily requirement of plant fiber. In non-insulin dependent diabetes it is forbidden to use oatmeal in the form of flakes or mixtures for instant cooking. In order not to provoke a sharp increase in the plasma concentration of sugar in the body, it is necessary to consume only whole grains.
Barley
Pearl barley has the lowest GI of all cereals recommended for non-insulin dependent diabetes mellitus. The glycemic index is 22 units, because barley is obtained from barley grains. The latter undergo grinding, during which the upper layers of cereals containing the largest amount of carbohydrates are removed.
Due to the low GI, pearl barley can be cooked not only as a breakfast, but also as a side dish for meat dishes. Grain crop benefits due to the active substances contained in it:
- vitamins: retinol, thiamine, pantothenic, nicotinic, folic acid;
- gluten;
- mineral compounds;
- antioxidants;
- various amino acids.
With regular use of barley porridge, there is an improvement in the condition of nails, skin and hairline.Vegetable fiber in the composition of the product improves intestinal motility and frees the digestive tract from the remnants of digested food. Antioxidants contained in cereals slow down age-related changes in the body.
Barley is not recommended for peptic ulcer in the acute period, during pregnancy and with increased gas formation in the intestines.
Millet
Millet has an average glycemic index of 40 to 60 units. Therefore, it is not recommended to use it often - 1-2 times a week is enough. Millet porridge is cooked only on water. After cooking, butter, sour-milk and dairy products should not be added to the dish. The benefits of a grain crop for a patient with diabetes mellitus are due to the nutrients included in its composition:
- complex carbohydrate structure, the basis of which is starch;
- fatty acids that positively affect the condition of the skin, hair and nails;
- in millet, the phosphorus content is 1.5 times higher than in meat products;
- B vitamins in the composition of the grain improve the conductivity of nerve impulses;
- 1/6 of the entire composition of cereals are amino acids.
Millet increases the tone of skeletal muscles, gives vigor and strength. The grain culture helps to eliminate toxins from the body, the antioxidants in the composition of the cereal form a complex with free radicals and safely remove them from the body. At the same time, millet is not recommended for use in the presence of frequent constipation due to low acidity of the stomach. In such a situation, the grains will not be digested and may worsen the condition of a person.
Wheat
The glycemic index of wheat groats is about 45 units. Due to the high fiber content, when passing through the intestinal tract, the grain culture stimulates the peristalsis of smooth muscles, reduces the amount of adipose tissue formed from excess glucose. Wheat contains pectins, which stop putrefaction and fermentation in the digestive tract and improve food digestion.
What is better to give up?
Some types of cereals can worsen the condition of a diabetic due to the high calorie content and the absence of a large amount of fiber in the composition.
- White or polished rice. Its grains contain up to 86% starch. Despite the complex carbohydrate structure, the chemical compound begins to break down even in the mouth under the action of alpha-amylase. When it enters the stomach, starch is finally broken down into glucose, which causes a sharp jump in blood sugar levels. White rice contains practically no fiber, so it is digested faster than other cereals.
- Instant oatmeal. The composition of such products is often supplemented with food additives, sugar and various dried fruits. In the latter, a large amount of fructose and glucose is concentrated.
- Semolina. It is made from wheat grains using varietal grinding. Due to the high degree of purification, plant fiber is destroyed, GI rises to 70.
With the use of such products, a sharp increase in plasma sugar concentration occurs, which can lead to the development of complications of diabetes mellitus. The negative consequences of the disease include retinopathy, impaired tactile sensitivity, diabetic foot. With a regular violation of diet therapy, the effectiveness of hypoglycemic drugs decreases.
Usage Tips
Nutritionists recommend eating cereals every day. To get the most benefit from the use of cereals, you should adhere to the following rules:
- do not exceed the daily norm of cereals, which is 150-200 g;
- cereals can be used together with boiled beets, cottage cheese or slices of bread with bran;
- coarse fiber is easier to digest in the first half of the day, because due to the high calorie content, the products increase the tone of the body and replenish energy reserves;
- you can sweeten the dish with xylitol or sweeteners;
- with daily use of cereals, you should alternate: if you plan to cook oatmeal on Monday, then on Tuesday you should try millet;
- do not add synthetic food additives to cereals, except for permitted fruits.
Before changing the diet, you should consult with an endocrinologist. Based on the results of the tests, the doctor will be able to tell you how much cereal you can eat per day and how often you can eat cereal.
