Everyone has heart about recommendations to consume more fruit, whether on diet or not. Containing large amounts of water, juicy and slightly sour with a pleasant taste, the fruits not only quench thirst but also help maintain water balance in the body, especially in the summer heat. Fresh fruits are the main natural source of easily absorbed vitamins. This is important especially for vitamin C, which is known to be easily destroyed by heat and being in a direct contact with oxygen from air. It is good to know that when the fruit is sourer, the vitamin C content in it is higher.
Fruits are also an indispensable source of carotenes, which are being converted in the body into vitamin A. The combination of vitamin C and carotene functions as a single vitamin complex, which has strong antioxidant activity. Oxidation processes occur continuously in all cells and tissues of the body and are the basis of cellular aging, carcinogenesis and cardiovascular diseases.
According to numerous research people who eat more vegetables and fruits suffer from heart disease and cancer more rarely.
The is a question whether people who are dieting to lose weight can eat unlimited fruits. To reach the correct answer, you need to know a few basics of the fruit as food.
Energetic value of fruit is determined by the content of carbohydrates in them, but it is too variable. It depends on both the species and varieties belonging to them, and the degree of maturity. These carbohydrates are basically three types. Fructose, also called fruit sugar, is the largest amount. It gives it a pleasant sweet taste of fruit. Glucose is another type of sugar that is quickly absorbed in the gut and almost immediately passes into the blood. Is known also under the name “Sugar effort” because very quickly “burn” muscle with increased physical activity. The third type is sucrose, whose molecule consists of one glucose molecule linked to one molecule of fructose. All of these carbohydrates have approximately the same calorific value – about 4 kcal / g. After they enter into the body, they can be used to meet energetic needs, fructose and sucrose are converted into glucose. However, if the quantity is too large and remain unused, carbohydrates turn into fat. Fruits are extremely low in fat and rich in dietary fiber but you should not overeat with them.
