Different types of fruits contain varying percentages of fructose , but all types of fruits cause high blood sugar and thus high insulin levels. Although fruits are a source of vitamins and fiber, diabetics and people who follow a low-carbohydrate diet should reduce their intake of fruits and natural honey. In this article, learn about the sugar found in fruits , how it affects blood sugar, diabetics, and which fruits are suitable for a low-carb diet.
Fructose
The sugar found in fruits is two types of sugar: fructose and glucose. The proportions of each differ in each fruit, but most of the amount of fructose is half of the sugar in the form of glucose and the other half in the form of fructose. Both of these sugars raise blood sugar levels, as Fructose turns into glucose in the body, and glucose is the form of sugar found in the blood.
Although fructose is in lower proportions than the sugar found in sweets and starches, fructose is also able to raise blood sugar and thus raise insulin levels as well. However, when compared between natural fruit sugar and refined sugar added to processed foods, refined sugar has harmful effects. Many healthy foods, and the most important sugars that are used in sweetened foods are the following:
- Corn syrup, which consists of 100% glucose.
- Fructose, which is fruit sugar.
- Galactose, which is the milk sugar lactose combined with glucose.
- High fructose corn syrup, which combines refined fructose and glucose but with a higher percentage of fructose.
- Maltose consists of two glucose units.
- Sucrose, or white sugar or table sugar, is equal parts fructose and glucose.
These sugars differ from fructose because they are processed and added in large quantities to foods and drinks. Although fructose raises blood sugar, processed foods raise blood sugar more and faster, as the body metabolizes processed foods faster than it metabolizes fruit. Because the fruit is rich in fiber, which prolongs the digestion process.
Fructose for diabetics
Sugar in all its forms, whether fructose or refined sugar, is a simple carbohydrate that the body converts into glucose, which in turn raises the level of the hormone insulin, which increases insulin resistance and thus increases the risk of developing prediabetes , which, if not managed well, may develop into diabetes. Of the second type .
People who suffer from type 2 diabetes should also avoid eating fruits rich in fructose and reduce them as much as possible. For example, it is possible to eat one fruit every few days. They should also include vegetables in their diet and eat a varied portion of vegetables with every meal. To obtain the vitamins, minerals and fiber necessary for the body.
Natural fructose
Whole fruit is always a better choice than packaged or processed fruit and better than fruit juices. Processed sugar is added to canned fruits to give them a stronger taste. Fruit juices are also heavily sweetened and highly processed. Flavored juices often contain large amounts of added sugars. These juices are not a substitute for whole fruit and may significantly increase a person’s sugar consumption.
Also, fruit juices, even if they are not manufactured, contain a very high percentage of fructose, even if they are prepared at home and no sugar is added to them, as the fruit itself is a source of sugar, considering that we squeeze several pieces of fruit to get one cup. Of fruit juice, this means that this cup contains high levels of fructose .
Therefore, fruit juices are not a preferred choice, especially for diabetics or people who follow a low-carb diet, as fruit juices, in addition to containing high levels of fructose , also do not contain the fiber found in fruits, which is very necessary to prolong the digestion period.
Fructose for diet
A low-carb diet requires reducing the amount of carbohydrates eaten. This does not only mean abstaining from eating pastries, baked goods, and sweets. Carbohydrates are also found in fruits, so you should reduce your intake of fruits. Although fruits are a good source of fiber and vitamins, they are also found in fruits. These essential nutrients can be obtained from vegetables.
Therefore, for people who follow a low-carbohydrate diet, eating vegetables is essential and must be eaten with every meal to obtain the fibre, minerals, and vitamins necessary for the body, while fruit intake must be reduced as much as possible to limit intake of vegetables.
