Citrus fruits: health benefits, nutrition, and tips for use
During the cold season, the media is calling for more consumption of fresh fruit to counteract ailments: colds, flu, and others that strain our immune system. Among the most recommended are citrus fruits. However, there are contradictory opinions, which partly detract from the valuable properties of these fruits. Is it true what they tell us? Are citrus fruits healthy allies or not?
Types of citrus fruits
Most people are familiar with oranges and lemons. Many species belong to the citrus family: oranges are the most important and commonly used. Mexico, India, the United States, Italy, China, Brazil, and Spain are the largest citrus producers.
Citrus sinensis is a fruit tree belonging to the genus Citrus whose fruit is orange, known as a sweet orange, a name used to distinguish it from bitter orange. They are probably the most popular citrus fruits, primarily because of their juices and known contribution of vitamin C. In addition to ascorbic acid (vitamin C), they also contain vitamin B1, folic acid, potassium, flavonoids, carotenoids, citric acid, and fiber. They are delicious and nutritious, which is the reason people mainly use them all over the world.
Bionde del Gargano oranges are a true perfection of tradition, protected by the prestigious European IGP brand. They have a relatively small size, a classic spherical shape, a sweet taste, and an intense aroma, making them particularly valuable among consumers. Bionda is produced and packaged in the province of Foggia, mainly in the northern coastal and sub-coastal area of Cape Gargano.
Oranges can be eaten fresh, sliced, or juiced as an ingredient in salads and as a side dish. Oranges can also be prepared as part of exquisite sweet and sour dishes or as an alternative for drinks, liqueurs, and lemonades.
Lemon has many health benefits, so it deserves its article. They recommend eating it sliced or in pieces with food to get the maximum help, and you can use it in a salad or other fresh dishes. Lemons are consumed all over the world, and their uses are uncountable.
Tangerines are as famous as oranges because of their flavor, but they are not always available. They contain calcium, so they keep bones and teeth healthy. Tangerines also contain bromine. This mineral has soothing and relaxing properties. If you are stressed, nervous, and agitated, a few tangerines in the evening before bed can help you fall asleep.
Lime is a little-known citrus fruit, often confused with lemon (it belongs to the same family) and little used. Unlike other citrus fruits, it does not have a lot of fiber but is high in vitamin C, magnesium, potassium, folic acid, citric acid, beta-carotene, and antioxidants. It is a good detoxifier, helps digestion, and has the same benefits as other citrus fruits. Several varieties taste different but are usually bitter.
Bitter is not to everyone’s liking. Grapefruit is one of the most rarely used citrus fruits because of its taste. A unique feature of grapefruit, when consumed regularly, is the prevention of insulin resistance and, as a consequence, diabetes.

This vitamin is especially effective for boosting the immune system and preventing or treating seasonal illnesses such as colds, coughs, sore throats, and the flu. It is also helpful for gingivitis, stomatitis, and infectious diseases.

Vitamin A is present, especially in tangerines and grapefruits, which is very valuable for vision, while the presence of B vitamins makes these fruits effective in combating feelings of exhaustion.
