Glycemic index of persimmon, apple and other fruits

Any product that contains carbohydrates, in addition to its energy value, has another important property. This is a glycemic index or a brief GI. This indicator directly affects the processes of obesity and weight loss.

What is the glycemic index?

Glycemic index is an indicator of the effect of consumed foods on human blood, more precisely, on the level of sugar in it. The glycemic index is a direct reflection of the comparison of the body's responses to glucose and some other nutrient. Here the main terms of the formula is the level of digestibility. The GI glucose is taken as the reference point, equal to 100.

If the glycemic index of food is considered low, then its use does not harm the body, as the sugar level will rise slowly. The higher the GI, the faster and worse the result will be the composition of the blood.

Products that are minimally harmful to the body have a low value - from 0 to 49. The average GI is in the range from 50 to 69. High - from 70 or more. For example, the glycemic index of persimmon is 50. Consequently, this product is average for the negative effect on blood sugar levels. GI directly depends on such factors as the amount of fiber and proteins, the type of carbohydrates, the method of heat treatment. For the first time, the glycemic index was discovered and introduced into terminology in 1981 by Canadian professor David Jenkins. In his studies, the doctor was looking for a cure for diabetes. After a series of experiments, Jenkins revealed a graph of the effect of the index on human blood. Scientists have been using it to this day.

Dangerous to blood products

A high glycemic index should become a wake-up call for each person. Products containing this indicator, after getting into the blood, rapidly increase the level of sugar in the circulatory system. This process stimulates the pancreas to make involuntary discharges of large amounts of insulin.

This hormone spreads sucrose through all the tissues of the internal organs of a person, transforming it into fatty deposits. In addition, it interferes with the process of cleavage of almost all harmful substances. Thus, insulin promotes the accumulation of fatty tissues, forcing the body to ignore their presence. It is for this reason that a person loses vital energy, accumulated for days.

It is highly not recommended to eat foods containing high GI daily, otherwise there will soon be a risk of obesity of the last degree or diabetes. Glycemic index of fruit and greens is considered one of the lowest, so many experts advise them for a regular diet. On the second place on GI are berries and some vegetables.

Glycemic Index: Persimmon

This tropical fruit is considered one of the most beneficial for the human body. Is this really the case, if the glycemic index of persimmon is 50? This indicator automatically assigns the fruit to the number of medium-risk for the level of sugar in the blood. On the other hand, the composition of the tropical fruit includes quite a lot of carbohydrates (up to 20%), so its degree of harm is minimized. In addition, this glycemic index of persimmon is considered by many scientists to be borderline (between medium and low). It should be noted that the fruit is well suited for various diets, as it is both nutritious and low-calorie (about 57 cal per 100 g). The composition of persimmon is enriched with disaccharides, fiber, potassium, magnesium, calcium, iron, phosphorus and other useful microcomponents. Also, the fruit contains many vitamins: carotene, ascorbic acid, thiamine, niacin, riboflavin.

Glycemic index: apple

This fruit has always been considered a curative product that helps many diseases. This is evidenced by the glycemic index of the apple, which is equal to 35. This allows the fetus to be on the list with a low GI.

The apple itself is a non-nutritive product. Its energy value barely reaches 47 cal. The presence in the fruit of a high level of vitamin C helps to reduce the permeability of the walls of blood vessels for toxins and to increase immunity. Also, apples are enriched with plant antibiotics, such as phytoncides, which neutralize the effect of influenza viruses, staphylococcus and dysentery. Of other nutrients in the fruit contains dietary fiber, citric acid, iron, potassium, pectins, antioxidant quercetin, iodine and others.

Glycemic Index: pumpkin

Some people refer this fruit to berries, but in everyday life it is considered to be a vegetable. In any case, the pumpkin, the glycemic index of which is 75, is among the plant products dangerous for the circulatory system. This indicator makes the melon fruit one of the most harmful vegetables in the traditional diet of man. The green pumpkin, whose glycemic index is 72, is also on the list of products with high GI.

On the other hand, the caloric content of the vegetable makes it indispensable in strict diets. Its energy value per 100 g does not exceed 22 cal. In addition, in the pumpkin a large number of disaccharides, starch, pectin elements, fiber, iron, calcium, organic acids, magnesium, potassium, vitamins B, C, E, PP, T. It is worth noting that the vegetable contains several times as much useful beta-pigment as carotene than in the same carrots and beef liver.

In non-traditional medicine the pumpkin is used for the prevention of jade, hypertension, inflammation of the urinary tract, hemorrhoids and many other diseases.

Glycemic Index: Vegetables and Fruits

These herbal products are not only nutritious and dietary, but also extremely useful, since they contain micro-components vital for the human body. The average glycemic index of fruits is similar to that of vegetables.

On the other hand, both types of plant food products have their own particularly harmful representatives. For example, the glycemic index of persimmon is 50. This fruit is allowed for everyday use. But with the dates have a very high GI - 103. In vegetables, such a representative, in the first place, is a rutabaga. Its glycemic index is 99. For reference - the most common products and their GI: apricot - 20, orange - 35, watermelon - 70, broccoli - 10, grapes - 44, peas - 35, pear - 33, raisins - 65, zucchini - 75, cabbage - 10, Potatoes - 70, strawberries - 32, lemon - 20, onions - 15, cucumber - 20, parsley - 5, beets - 70, beans - 30.

Glycemic index: sugar

It's no secret that sweets were always and everywhere considered one of the most harmful food products from different points of view. So, the glycemic index of sugar is equal to 70. This brings the product into the number of dangerous with high GI. A little less harmful for the composition of blood is sucrose. Its glycemic index is 60. The most useful of the analogues of sugar is fructose. Her GI is only 20.

One of the most harmful sweets with a high glycemic index are wafers (80), caramel (80), jam (70) and jelly marmalade (70). However, the champion of GI is honey. His indicator of influence on sugar in the blood is 90. The most harmless is the bitter chocolate (up to 25).

Glycemic index: cereals and cereals

Scientists have long been proven that crops are extremely important for human health. That is why cereals are so popular in the ration of athletes. Glycemic index of cereals, on average, is in the range from 45 to 65. As for cereals, their GI varies from 22 to 70.

The lowest glycemic index for wheat and barley cereals is 45, and the highest for manna (65). Among the grains, brown rice is the most useful (49).

It should be noted that GI pearl bar is made only 22, when buckwheat - 50.
