What fruits, vegetables and berries can be eaten with diabetes?
Diabetes mellitus is a disease in which the patient's well-being is largely due to his diet. This raises many questions regarding the permissibility and prohibition of certain foods in the diet of a person with diabetes. In particular, disputes are being waged regarding vegetables, fruits, and berries. Let's consider this issue in more detail.
Allowed and prohibited products
Diabetes mellitus is a disease characterized by the absence or small amount of insulin. It is not produced by the pancreas or is synthesized in insufficient volume. As a result, sugars (glucose, fructose, sucrose) entering the body are not broken down and enter the blood in high concentrations. This causes a sharp rise in blood glucose levels.
With a significant increase in the patient's condition deteriorates significantly - up to the onset of coma.
There are 2 types of disease. With type 1 Insulin is not produced at all, so it is injected. For each patient, an individual dosage is calculated for him. With diabetes 2 types insulin is produced by the pancreas, but in insufficient quantities. You can avoid sharp glycemic spikes if you control your diet. It is allowed to eat those foods that cause an acceptable increase in glucose levels.
All available products for diabetes can be classified into one of three groups.
- Approved for diabetics. The products of this group have a low glycemic index (GI) (does not exceed 55 units), so they are allowed to be consumed daily - this is the basis of nutrition.
- Permissible - that is, those that are safe for moderate and infrequent use. This group of acceptable products for diabetes includes those that have an average glycemic index of 55-70 units.
- Forbidden - they cause a sharp increase in blood glucose levels. A forbidden food is one that has a high GI, about 70 units.
Below is a table of the GI of various vegetables.
Low GI | high GI |
Tomatoes, eggplant, zucchini, zucchini, lettuce, broccoli, spinach, red peppers, onions, radishes, white cabbage, all types of legumes (the exception is the beans themselves) | Beets, corn, pumpkin. Potatoes have a high GI and are low in fiber, which causes a sharp glycemic rise. |
However, when choosing vegetables it is impossible to focus only on the value of GI, it is desirable to take into account such an indicator as the glycemic load. The latter implies a proportional ratio of fast carbohydrates to the rest of the elements of the product (measured in grams).
The lower the weight value, the safer the product for a diabetic. Some of the vegetables listed in the second column of the table (beets, corn, pumpkin) have a small glycemic load, therefore, in small quantities and with rare use, they are allowed for this disease. On average, their dose is about 80 g per day (2-4 times a week). For slower digestion of carbohydrates from these vegetables it is better to combine them with healthy fats (vegetable origin, as well as sea fish, avocados) or proteins.
The following list focuses on fruits and their GI values.
Low GI | Average GI | high GI |
Currant (30 units), cherry (20 units), sea buckthorn (30 units), gooseberries (40 units), strawberries (30 units and low calorie content), sweet cherries (25 units), plums (25 units) ), apricots (20 units), nectarines (35 units). | Raspberries (you can consume in small quantities, but the product still provokes glycemic jumps), bananas, persimmons. | Grapes (70 units) - for type 2 diabetes, it is preferable to eat a few raisins than fresh fruits, watermelon (the most dangerous berry for diabetes, instantly provokes jumps in glycemia, acting stronger than boiled potatoes and white rice), melon (it also high concentration of fast carbohydrates and minimal amount of dietary fiber). |
Low GI | Average GI | high GI |
Pears (34 pts), Apples (30 pts), Peaches (30 pts), Grapefruit (22 pts), Oranges (35 pts), Pomegranate (35 pts), Avocados (10 pts, from the point botanical view is a fruit) | Tangerines (40 units) | Pineapples (66 units) |
How can they affect the body?
As for juices and fruit purees, it is better for diabetics to refuse them. This is due to the fact that these products have a high concentration of fast carbohydrates. In addition, they are devoid of fiber, which reduces the rate of absorption of sugars from the intestines. That's why after drinking juices and mashed fruits and berries, a sharp glycemic change occurs.
Dried fruits also cause a lot of controversial issues. Despite the healing characteristics of dried fruits, they are more high-calorie and sweeter. This is due to the fact that there is no water in dried fruits, due to which the concentration of all other substances increases. Nevertheless, dried fruits are allowed for diabetes, but not daily and in small quantities.When recalculating the level of glucose in dried fruits, 20 g is taken for 1 XE.
Based on this, 4–5 pieces of dried apricots or prunes can be considered permitted.
In case of illness, it is important not only the amount of fast carbohydrates in the product, but also the rate of their absorption. It depends on the consistency, the presence of fats and temperature. Carbohydrates from hot foods are absorbed faster. Fats, like dietary fiber, slow down the absorption of sugars. Finally, from foods with a coarser consistency (again, the merit of fiber), carbohydrates are also absorbed more slowly.
Despite the beneficial ability of fats to slow down the processes of glycemia, It is worthwhile to consume foods rich in fats with caution. They can cause weight gain, and diabetics already have a tendency to become obese. Features of diabetes and the need to follow a diet can provoke a lack of certain substances in the body of diabetics, the appearance of concomitant diseases.
In many ways, fruits and vegetables help to fill the existing deficit. So, red pepper not only lowers the level of glucose in the blood, but also prevents the formation of cholesterol plaques on the vascular walls. But tomatoes, which also have a low GI, on the contrary, when consumed excessively, destroy the amino acids necessary for the functioning of immunity and metabolic processes.
Traditional medicine speaks positively about white cabbage juice. It is an effective means of lowering glucose levels, it contains a high content of vitamin C. The latter helps to strengthen the immune system, such support is needed by the body depleted by the disease. Allowed for consumption, berries with low and medium GI become one of the main sources of vitamins, provide the body with minerals and antioxidants.The fruit acids present in the composition help to improve digestion.
However, it is important to understand that with increased acidity of the stomach, the presence of gastritis and ulcers, sour berries (cherries, red currants, strawberries, gooseberries) are prohibited.
The leaves and dried fruits of blackcurrant are used to prepare a medicinal decoction. It lowers sugar levels, provides the body with ascorbic acid, can be used as a therapeutic and prophylactic anti-cold remedy, allows you to eliminate cholesterol plaques on the walls of blood vessels, and prevents the formation of new ones. Cherries have a low GI and contain a substance called coumarin. It reduces the viscosity of the blood, which prevents thrombosis.
However, with problems with blood clotting, this berry should be used with caution. In addition, cherries are rich in minerals and contain anthocyanins. The latter are characterized by many useful properties, among which is the reduction of glucose levels.
Pears and apples, in addition to a small amount of sugar, include fiber, which is necessary for the digestion of food, intestinal motility. Thanks to dietary fiber, the glycemic indicators of these fruits seem to be slightly reduced.
You need to eat the fruit with the skin, since it is in it that the main amount of fiber is concentrated. In addition, these fruits, available at any time of the year, contain vitamins and minerals. Plums have a similar property, which, when fresh, can also be used as a laxative and diuretic with a mild effect. Plum fruits and leaves help with high blood pressure.
Obesity often accompanies diabetes.People for whom the problem of excess weight is relevant should focus not only on the GI, but also on the total calorie content of fruits and berries. In this case, citrus fruits (oranges, grapefruits) are preferable than peaches, pears. It is better to exclude not only sweet fruits, but also berries.
With this disease in the body, there is also an increased accumulation of free radicals, which reduce immunity and can cause cancerous tumors. Beta-carotene (a precursor of vitamin A) avoids such accumulations and is available in large quantities. in plums, grapefruit, blueberries. With the disease, there is also a deficiency of chromium in the body. Meanwhile, it is necessary for the flow of metabolic processes. A lot of chromium is present in quince, cherry, sweet cherry.
Manganese is required for the production of insulin. In addition, it reduces the risk of obesity of the internal organs, which is a common picture in diabetes. Manganese is found in large quantities in raspberries, blueberries, and black currants.
If you decide to eat currants, choose dark-colored berries, they are richer in composition when compared with red and white currants.
Recommendations for use
Most fruits and vegetables are best eaten raw. This is due to the fact that during heat treatment, complex carbohydrates are transformed into simple ones. The latter are absorbed faster, so the GI of cooked vegetables is higher than that of raw vegetables. For comparison: GI raw carrots - 35%, boiled - 85%. The longer the heat treatment of vegetables, the higher their GI rises.
You should also refuse the consumption of pickled, salted vegetables. They contain too much salt and spices, which can cause heart problems, swelling, and contribute to obesity.As you know, diabetics are already predisposed to these ailments.
If you are preparing compote from dried fruits, then they should first be soaked in water for 6-8 hours, drain the water, rinse the fruits, and only then cook the compote. First, water for compote is boiled, and dried fruits are already placed in the boiling liquid. So it will be possible to avoid increasing the GI of the finished drink, as well as to preserve the maximum of vitamins. You can also cook compotes from fresh fruits, but you should choose unsweetened fruits.
In case of diabetes, vegetables are consumed fresh as an independent dish, salads and side dishes are prepared from them. For dressing salads, it is recommended to use vegetable oil or non-caloric sauces based on it. For fruit tasting, it is better to allocate a separate meal, preferably in the morning. Fruits with an average and especially high GI can be consumed in small quantities twice a week. For example, the daily norm of a banana is 1/2 fruit.
Fruits with low and medium GI values should be consumed on average 100–150 g each (depending on the type of fruit). This standard is better divide into 2 servings. By the way, a banana is one of the few fruits in which the level of glucose decreases during baking or frying. Another paradox is that the banana itself after such processing becomes even sweeter in taste.
It is not recommended to combine several types of fruits and berries in one meal. As an option, combine sweet and unsweetened fruits, but they should all have a low GI.
All fruits and berries must be ripe. Overripe ones contain more sugar, can provoke fermentation processes in the intestines and poisoning. Unripe ones are usually too starchy, taste bad, and can also cause stomach problems.To increase the duration of the process of assimilation of carbohydrates, fruits and berries can be combined with coarse fiber - bran, bread, long-cooked oatmeal.
Important! All of these recommendations are valid if gestational diabetes is detected in pregnant women. It usually occurs in response to hormonal changes.
