Diabetes Diet

Fructose in diabetes - can or not

Organic compounds from the category of carbohydrates include fructose or fruit sugar. This sweet substance in various dosages is present in berries, fruits, honey, vegetables, and contains 380 kcal per 100 g. Therefore, the question is whether diabetics can have fructose is particularly relevant, since the pancreas of these people cannot cope with the breakdown of sugar coming into an organism. A person with a similar diagnosis should carefully follow a diet, analyzing the composition of certain products. What are the features of fructose, and is it really good for the body, as some experts believe?

What is fructose

A person becomes insulin-dependent in diabetes mellitus type 1, because his body does not produce the most important substance - insulin, which normalizes the concentration of sugar in blood cells. Metabolic processes are disturbed, a lot of comorbidities occur, which, if not treated, progress and can lead to serious consequences. With type 2, insulin is produced, but in insufficient quantities.

Various factors can provoke the development of pathology:

  • problems with pancreatic activity;
  • heredity (if one of the parents suffers from a “sweet affliction”, then the probability that the child will have diabetes is 30%);
  • obesity, in which metabolic processes are disturbed;
  • infectious diseases;
  • long life in stress;
  • age changes.

Diabetes and pressure surges will be a thing of the past.

  • Sugar normalization -95%
  • Elimination of vein thrombosis - 70%
  • Elimination of palpitations -90%
  • Excessive Blood Pressure - 92%
  • Increased vigor during the day, improved sleep at night -97%

With the development of diabetes, the victim visibly loses weight (or, on the contrary, gains weight), experiences a strong feeling of thirst, complains of shortness of breath, frequent dizziness. The diagnosis is made only after an appropriate examination, which allows to establish the type of diabetes. If the doctor reports such a diagnosis, the person should be prepared to follow a low-carb diet and avoid sweets. They can be replaced by fructose or other sugar substitutes. But when used, one should strictly observe the dosage and do not overdo it, otherwise there will be unpleasant consequences.

Levulose (also called fructose) is the simplest monosaccharide that human cells, after digestion of glucose, use for energy. Its main sources are:

To find out whether it is allowed to use fructose in diabetes, you need to find out how it affects the body. Getting into the digestive organs, this substance is broken down slowly. Most of it is absorbed by hepatocytes, i.e. the liver. It is there that fructose is converted into free fatty acids. Because of this process, the further absorption of fats is blocked, which contributes to their deposition in the body. Adipose tissue while increasing, causing the development of obesity.

But to completely exclude fructose from your diet should not be. Its glycemic index is quite low. In order for the substance to be properly absorbed, the cells do not need insulin synthesis. Although, to saturate the cells, as well as glucose, fruit sugar can not.

Important! Fructose for diabetics is valuable because it is slowly absorbed by the body and practically does not require the introduction or release of insulin.

Fructose - the benefits and harm for a diabetic

Fruit sugar is a natural carbohydrate, so it is very different from regular sugar.

With type 1 and type 2 diabetes, fructose is beneficial due to:

  • low calorie;
  • slow absorption;
  • the absence of a destructive effect on tooth enamel;
  • removal of toxic substances, including nicotine and heavy metal salts;
  • full absorption by the body.

But fructose consumption in type 1 and type 2 diabetes is not always helpful:

  • absorbing fructose-containing foods, a person does not satisfy hunger, therefore, does not control the amount of food eaten, which contributes to the development of obesity;
  • in type 2 diabetes, fructose is not able to satisfy hunger, because it contains the hormone ghrelin, which is a hormone of hunger, which can also lead to excessive consumption of food;
  • Juice is concentrated a lot of fructose, but there is no dietary fiber, which significantly inhibit the absorption of carbohydrates. Therefore, they are processed quickly, which contributes to the release of glucose into the bloodstream. It is extremely difficult for a diabetic to cope with this process;
  • using a lot of fresh juices, a person runs the risk of encountering cancer pathologies. Even healthy strong people are not recommended to take more glass of undiluted juice per day. Diabetics should be at least halved;
  • if you eat too much fructose, you can overload the liver, where it splits;
  • This monosaccharide is a sugar substitute. If you use a commercial product, then diabetics face an uncomfortable form of release and do not dose it correctly. So in tea you can accidentally put two spoons of fructose instead of the required half.

Useful: Stevia - a natural sweetener for diabetics

In case of diabetes mellitus, fructose is considered harmless, the source of which is fresh fruit and vegetables. An industrial product contains 45% sucrose and 55% fructose. Therefore, diabetics should use it in a limited amount, especially if the person is insulin-dependent.

Sugar or fructose

More recently, experts have argued that with the help of fructose it is quite possible to cure type 2 diabetes and actively recommended it for use as a safe sugar substitute. But if this monosaccharide is compared with sucrose, some disadvantages can be identified:

FructoseSucrose
Considered the sweetest monosaccharideNo pronounced sweetness
Slowly enters the bloodstreamRapidly absorbed into the bloodstream
Is broken down by enzymesSplits with insulin
Does not saturate cells with energyRestores cellular energy balance
Does not affect the state of the hormonal backgroundImproves hormonal balance
Does not give a feeling of satietyEven a small volume satisfies hunger.
Has a pleasant tasteIt has an ordinary, unremarkable taste.
Considered a powerful antidepressant.
Calcium is not required when splittingCalcium is required for cleavage
Does not affect brain work.Promotes brain activity
Low calorie elementHigh calorie element

Since sucrose is not always quickly processed by the body, it often causes obesity, which is necessarily taken into account in type 1 and type 2 diabetes.

Important! Fructose is sweet to the taste and satisfies the taste needs of a diabetic. But the brain is energized only by glucose, which is not available in fructose.

Sorbitol or fructose

It is known that fructose in diabetes in large quantities can harm the body and increase the concentration of sugar. As for the other sweetener - sorbitol, it also does not always benefit the person, especially in large doses. Experts do not see a pronounced difference between fructose and sorbitol.

Use of sorbitolThe benefits of fructose
Improves intestinal microfloraTones, uplifting, improves performance
Serves as an effective choleretic agent.Reduces the risk of caries

Harm from the increased use of sorbitol can provoke an upset function of the intestine, cause flatulence, bloating, colic. Consumption of higher fructose increases the risk of diseases affecting the cardiovascular system. Therefore, choosing a sugar substitute for diabetes, you need to strictly follow the recommendations of the doctor.

Important! During pregnancy and lactation, sweeteners are prescribed with extreme caution. Independently decide on the admission of a substance in this period is dangerous.

How to use fructose in diabetes

The dosage of consumption of fructose depends entirely on the severity of the disease. In case of a mild course without using insulin injections, it is allowed to take from 30 to 40 g of monosaccharide per day. In this case, preference should be given to fructose contained in vegetables and fruits.

If the specialist allows, then you can use products containing industrial glucose. They must be eaten in strictly limited quantities, since besides the sugar substitute, they may contain starch and flour, the main sources of light carbohydrates. In the supermarkets on the shelves for diabetics you can find the following types of products containing fructose:

  • chocolate bars and candy bars;
  • waffles;
  • halva;
  • jam;
  • jelly;
  • condensed milk;
  • muesli
  • pastries and cakes;
  • marmalade.

On the packaging of such goods is always indicated that they are made without sugar and contain fructose. In severe forms of diabetes, use of fructose in the diet. agreed with your doctor.

It is possible or not to use fruit sugar in diabetes, many patients are interested. This important component for the metabolism, if there are no serious pathologies, it is completely resolved by the sick. But the person should make the diet, being based on recommendations of the doctor.
