Pineapple is a fruit native to South America. Christopher Columbus delivered pineapples to Europe after one of his expeditions. They began to grow them on a large scale in Hawaii at the beginning of the 19th century. The development of the “pineapple” industry peaked in the 1950s, then gradually declined under pressure from international competition. Today, the bulk of the world’s pineapple harvest is in Thailand, the Philippines, and Brazil. Traditional pineapple uses include brewing and winemaking, as well as medicine.

Due to its rough and textured skin and a crown of spiky green leaves, pineapple does not seem to be a very attractive-looking fruit. But its flesh is delightfully tender and juicy, has a sweet taste and pleasant aroma. Although fresh pineapple is used in many diets, excessive consumption of this fruit can lead to unpleasant side effects.

The composition of pineapples: calories, trace elements, vitamins

Nutritionists call pineapples “champions” in burning excess fat and improving the functioning of the intestines, digestive system, and pancreas. These fruits are very often present in many diets when you need to lose weight and lose weight urgently.

Pineapples can also boast of the content of bromelain (a special enzyme complex) in its composition. Thanks to it, the rapid breakdown of proteins and fats occurs, which is why pineapples contribute to active weight loss. But bromelain is found only in fresh fruits, so when dieting, you need to use only fresh fruits. In canned sweet pieces this useful substance is no longer there. Therefore, nutritionists advise a simple “recipe” on how to keep fit: you need to drink food with freshly squeezed pineapple juice or eat a small piece of this fruit after eating.

In pineapples, there are enzymes – these are special substances that contribute to the better digestion of food. They rejuvenate the body, resist viruses, and inhibit the unfavorable growth of cancer cells.

Pineapples are a low-calorie product. 100 grams contains an average of 49 kilocalories. The yellow pulp is very sweet and juicy due to the fact that pineapples are 15 percent sugar and 86 percent water.

If the sweet rings were canned in sugar syrup, such pineapples will be of little use. The treat will be very high in calories due to the high amount of sugar. In addition, citric acid is added to sugar syrup, which also does not contribute to the usefulness of such a product.

Canned pineapples perfectly satisfy hunger.
