When we think about the benefits of oranges, we immediately associate it with the fight against colds and flu, as we know of the high amount of vitamin C present in this fruit, which is so popular in Brazil.
According to nutritionist at Oba Hortifruiti, Lívia Nogueira, four types are preferred Brazilians. “The most consumed oranges the population are lime, pear, land and bay. Among the most popular ones, the orange from the land is usually the most acidic”, he explains.
With the scientific name Citrus sinensis, this fruit is one of the many that make up the group of natural citrus fruits. But in addition to boosting immunity, it also protects the skin and improves vision. For these and other benefits, it is considered a functional food.
According to an article published the Brazilian Society of Food and Nutrition (SBAN), the fruit has properties in all its parts and therefore can be used in its entirety. For example, while the pulp and bagasse can be used in juice and orange cake, the peel makes an excellent tea.
Benefits of orange
“All oranges have the same types of nutrients, and they can only differ in the amount of these nutrients in relation to the type of orange. They are rich in vitamins C, A, B, calcium, magnesium, potassium, among others”, explains Nogueira, a specialist in Clinical and Functional Nutrition.
1. Fights colds and flu
The first positive effect of this fruit is also the most popular, fighting diseases such as flu and colds. And as expected, Lívia Nogueira explains where this benefit comes from: “As they are a great source of vitamin C, oranges strengthen the body’s immunity”. However, they are also good remedies for those who have asthma, fevers and even to strengthen the airways. ( 2 )
Another way to help strengthen the body is to avoid anemia . This problem is characterized a decrease in the size or number of blood cells, called red blood cells or white blood cells. This can occur due to several factors, the main one being iron deficiency, but lack of vitamin C can also trigger this condition. ( 3 )
2. Protect the skin
Also due to the presence of vitamin C , consumption of the fruit “slows down the effects of premature aging and helps in good healing”, says Nogueira. This effect occurs because the nutrient in question acts as a co-factor in the biosynthesis of collagen , a protein capable of strengthening and giving rigidity to the epidermis. ( 4 )
In addition, the vitamin also has an antioxidant action, blocking free radical damage in the body. For example, when the body has these molecules in excess, they end up causing oxidative stress on cells. This results in a series of damages such as the emergence of degenerative diseases and skin aging.
But since there is a large consumption of antioxidant foods , we can protect the body from the harmful action of radicals. Even contributing to the reduction of cancer risk.
3. Improves vision
Also according to the nutritionist, oranges are also rich in vitamin A, which is excellent for eye health, as it helps to prevent chronic eye diseases. This effect is even more important in childhood, as this nutrient deficiency is the main cause of preventable childhood blindness.
Not to mention the vitamin’s benefits during pregnancy, because the embryo needs this nutrient to develop, especially in the first two and three weeks of pregnancy. Therefore, it is essential in bone metabolism, in the formation of lower and posterior limbs, etc. ( 5 )
4. Cleanses the body
Nogueira explains that the composition of this fruit, rich in water and vitamin C, results in a detoxifying effect on the body. According to the Brazilian Table of Food Composition (TACO), the water level in 100 grams of the main types of orange (bay, earth, lime, pear and valence) varies between 85% and 89%. ( 6 )
This liquid helps in the excretion of toxic substances from the body, as it is essential in physiological processes, increasing urinary flow. In addition, water hydrates, helps in the transport of nutrients, helps to regulate body temperature and is necessary for the functioning of the kidneys, intestine and circulatory system. ( 3 )
5. Protect the heart
Vitamin C is not the only nutrient present in this fruit with antioxidant action, as there are also other compounds such as citrus flavonoids. In a study carried out the Faculty of Pharmaceutical Sciences of Araraquara, São Paulo, it was possible to verify that orange juice has a vasoprotective action due to this phytonutrient.
This means that the natural drink can act as a reducer of bad cholesterol, high blood pressure and platelet aggregation. At the same time, consumption of the juice for consecutive weeks can increase the level of good cholesterol in the body, protecting heart function and preventing problems such as coronary artery disease.

6. Good for digestion
According to the nutritionist, this functional food has fiber in its composition, as well as other fruits and vegetables. For this reason, it is able to maintain a good functioning of the intestine , even preventing cancer in this region.
