Bananas – Carbohydrates, proteins and fats – Do bananas have sugar?

The banana, also known as plantain, banana, or guíneo, is one of the most popular and accessible fruits.

One of the most frequent myths about this fruit is that it makes you fat. Although it can be said that one of the nutritional properties of banana is that it is relatively high in carbohydrates (and therefore contributes a significant amount of calories), to affirm that the banana is fattening is a mistake.

This article analyzes the properties of the banana, its amount of carbohydrates, proteins, and fats. Contains sugar?

What is the banana?

The banana is an edible fruit, botanically a berry of a plant of the genus Musa. Banana plants look like a sapling and are called banana trees.

The banana is a fruit with variable qualities in size, color, and firmness. The pulp of the banana is rich in starch (a carbohydrate ) and is covered with a peel, which can be green, yellow, red, or brown when ripe.

All bananas are sterile fruits that do not produce seeds; this is because they have been genetically selected.

Banana carbohydrates

The banana provides about 22 grams of carbohydrates per 100 grams.

Of your carbohydrates, about 12 grams are sugar, 3 grams are fiber, and the rest are starch.

Although the banana has carbohydrates, to say that the banana is fattening is a mistake.

According to the WHO, 60% of daily calories must come from carbohydrates. This is the equivalent of consuming 300 grams of carbohydrates per day for a person who needs 2000 calories per day.

Therefore, eating one or even two bananas per day would cover less than 25% of a person’s carbohydrates per day. Banana carbohydrates are an excellent option to eat after training.

Do bananas have sugar?

The banana starch, complex carbohydrates, or starch are gradually converted into sugar in the ripening process. The more ripe the banana, the more sugar it contains.

Every 100 grams of a ripe banana, there are about 12.2 grams of sugars, mainly glucose and fructose.

So it is always better to eat bananas that are not too ripe. In this case, the carbohydrates in the banana are accompanied by a high content of vegetable fiber, so they are healthier.
