Watermelon is rich in lycopene, which is the dyeing substance that gives watermelon its peculiar red or pink colour.

Lycopene, is the same component to which tomatoes owe their red color. This component is very beneficial because of its medicinal properties for the body. Among all of them, we can point out the prevention of many types of cancers or its power to lower bad cholesterol.

Among all, specially pyridoxine (vitamin B6) whose function in the body is to metabolize carbohydrates, fats and protein. besides regulating the nervous system. A lack of this vitamin can cause, among other symptoms, nervousness, sleep problems, learning difficulties or muscle weakness.

Watermelons are fruits with a low content of carbohydrates, they contain approximately 7 gr of sugar for two pieces (100g). To make a comparison, blueberries (which are one of the fruits with fewer carbohydrates) have 4g of sugar per 100g serving. And a large piece of apples or oranges (about 150-200g) have between 15 and 18gr of sugar.

Differences between watermelons and melons

Although watermelon and melons are fruits belonging to different plants, people are often trying to compare one with another. Even when they appear in supermarkets there is a tendency to put them against each other as if they were brothers.

More than brothers, we could say that they are "cousins". Both belong to the same family (Cucurbitaceae) but to different genres (Citrullus and Cucumis, respectively). This relationship gives these two fruits very similar food properties.

The first thing people ask is which of them should be more slimming. It is normally believed that watermelon has a lot fewer calories than melon and therefore it is less fattening. The differences are very small. 100 g of cantaloupe or honeydew provide 35 calories, while 100 g of watermelon provides 32, which indicates that they have virtually the same caloric power.

If we consider that the potassium content of watermelon is nearly half that of the melon, you probably come to the conclusion that melon can be better than watermelon in the diets of people who want to remove fluid or lose weight.
