Grapefruit, the beneficial citrus for health

Grapefruit is a citrus fruit rich in vitamins and nutrients beneficial to health . Citrus fruits in general and grapefruit in particular, can help us strengthen our defenses , protect us from external infections and give us vitality.

Likewise, they improve the appearance of our skin, among many other nutritional benefits that they contribute to our health.

What is grapefruit?

Grapefruit, also called taronja or pink grapefruit , is a citrus fruit that is classified within the group of acidic fruits . Likewise, it is a tropical fruit that stands out for its sweet and somewhat bitter taste.

It belongs to the Rutaceae family and comes from the Citrus paradisi tree , also called pomelero or grapefruit . It is covered by a thick, yellow or pink skin.

Likewise, it is a well-known fruit in our markets, unlike other acidic fruits that are equally recommended, such as chayote .

Origin of grapefruit

The origin is not very clear , although there are experts who say that they are hybrid fruits between pampelmusa and sweet orange. It seems that it was discovered by chance in the plantations of the Caribbean Sea, around the 17th century. After the discovery, it spread throughout the American continent and its cultivation is mainly carried out in tropical and subtropical areas.

Its main global producer is the US , with more than 50% of world production. In addition, there are other important producers that are Argentina, Cuba, Cyprus, Israel, Mexico, Mozambique and South Africa.

Although Spain is not a country with a tropical or subtropical climate, there are grapefruit crops , especially in areas of Valencia and Murcia, which are exported to different national areas.

However, Spain is also exported to other areas of Europe which, thanks to its health benefits, is increasing its consumption.

How is grapefruit consumed?

As always, we recommend the consumption of fresh, raw and seasonal fruits .

We can include it in our diet as table fruit, although it is also often used for breakfast or snacks. Likewise, it is ideal both in the form of juice and fresh fruit.

It is also used in different jam recipes or preparations such as pink grapefruit bars. In addition, it is very common to consume this food in salads .

It gives us different nutritional properties and the great antioxidant power that can help us against different types of diseases. Therefore, encouraging the consumption of grapefruit in our diet can help us in our health.

Grapefruit season

Grapefruit has a very similar season to other citrus fruits such as lemon, orange or mandarin.

The grapefruit season in Spain runs from December to April, although some varieties are also harvested in November and May.

You can check the calendar of the  fruit season  to be able to consume these foods at their most optimal moment. In addition, when they are in season they provide us with  more benefits for our health, they have a better aroma and are tastier , among other advantages.

Nutritional properties of grapefruit

Grapefruits have a low caloric value, largely due to the fact that they are rich in water . As is well known, grapefruit is a great source of vitamin C and folic acid .

As minerals, potassium and magnesium stand out . The presence of malic, oxalic, tartaric and citric acids , responsible for its flavor and on which various properties that are attributed to grapefruit depend, is noteworthy .

It is more advisable to consume this food raw to take advantage of the fiber , although it is not very representative in this food. This fiber is found mainly in the white part of the pulp , which is the part that is consumed when we eat it raw.

If the consumption is made in the form of juice, the fiber is barely perceptible . It also contains carotenoids , only in dark flesh grapefruits.

Grapefruits provide antioxidants, as they are rich in flavonoids such as narigin and quercetin . These elements are the main responsible for the characteristic flavor of these foods.
