Oranges provide essential nutrients such as vitamin C, flavonoids, dietary fiber, potassium, and folate, which play important roles in human metabolism and immune regulation.

1. Vitamin C: Oranges are rich in vitamin C, which promotes collagen synthesis, enhances the activity of immune cells, helps the body resist pathogens, and aids in iron absorption, thereby reducing the risk of iron-deficiency anemia.

2. Flavonoids: The flavonoids in oranges are natural antioxidants that help eliminate free radicals, reduce oxidative stress, offer certain protective benefits for cardiovascular health, and assist in regulating inflammatory responses.

3. Dietary Fiber: The dietary fiber in oranges promotes intestinal motility, increases stool volume, facilitates bowel movements, reduces the retention time of harmful substances in the gut, and helps control the rate of post-meal blood sugar rise.

4. Potassium: Potassium plays a role in regulating electrolyte balance, supports normal myocardial contraction, helps regulate blood pressure, and maintains cardiovascular system stability.

5. Folate: Oranges contain a certain amount of folate, which is an essential component for nucleic acid synthesis and plays a vital role in cell division and growth. Particularly for women who are planning pregnancy or are pregnant, adequate folate intake supports fetal neural tube development.

When consuming oranges, it is recommended to wash the peel thoroughly and eat the fruit with the peel, or retain some of the peel when making juice, to obtain more dietary fiber. Avoid excessive consumption to prevent gastrointestinal discomfort. Pairing oranges with grains or protein-rich foods can enhance nutrient absorption efficiency.

What fruit is the fastest for relieving cough?

If cough persists for more than a week or is accompanied by symptoms such as fever or coughing up blood, prompt medical attention is necessary.
