Boost immunity: natural sources of vitamin C

The most outstanding health value of oranges lies in itsHigh vitamin C content. Each 100 grams of oranges contains about 53 mg of vitamin C (data source: United States Department of Agriculture), which is close to 60% of the recommended daily intake for adults. Vitamin C can stimulate the production of white blood cells and enhance the body's ability to fight viruses and bacteria. The traditional Chinese medicine classic "Compendium of Materia Medica" also records that oranges "moisten the lungs and resolve phlegm, produce body fluids and quench thirst" and are suitable for preventing colds in autumn and winter. In addition, vitamin C can also promote collagen synthesis and accelerate wound healing. It is recommended to eat 1-2 medium-sized oranges every day, but avoid eating them on an empty stomach to avoid stimulating gastric acid secretion.

Dietary fiber: the "scavenger" of intestinal health

rich in orangesdietary fiber(2.4 grams per 100 grams) can promote gastrointestinal motility and relieve constipation. Among them, pectin, as a soluble fiber, can form a gel-like substance in the intestines, absorb fat and toxins and excrete them from the body. The Chinese Nutrition Society recommends a daily intake of 25-30 grams of dietary fiber, and one orange can provide about 10% of the requirement. It is worth noting that the white inner peel of oranges (tangerine peel) contains a lot of fiber and bioflavonoids, and it is recommended to eat them together. For those with indigestion, you can squeeze the juice and drink it, but you need to keep part of the pulp to retain fiber.

Antioxidant and cardiovascular protection

A 2017 study in the European Journal of Nutrition pointed out that long-term intake of citrus fruits can reduce the risk of cardiovascular disease by 23%. The potassium in oranges (181 mg per 100 grams) helps balance sodium levels in the body and helps regulate blood pressure. The American Heart Association recommends eating oranges as part of a diet low in sodium and high in potassium. It should be noted that people with abnormal kidney function need to control their potassium intake, and it is recommended to consult a doctor.

However, it should be noted that oranges contain fructose, so diabetic patients should consume them in moderation; those with excessive stomach acid should avoid eating them before meals. Traditional Chinese medicine believes that orange has a slightly cool nature, and those with weak or cold constitutions can use ginger to reconcile it.
