The best ways to prepare oranges for sports, while preserving maximum nutritional value:
Before training (1 hour) - for hydration. After training - for vitamin C.

One medium orange or two smaller ones — a good serving. Whole fruit is better than juice because fiber remains and sugar is released more slowly. Suitable as a snack before or after training together with a protein source.
Choose heavy, firm fruits with smooth peel; color does not necessarily indicate ripeness. At room temperature oranges keep for about a week, in the refrigerator — longer. Consume peeled ones the same day.
Oranges are rich in vitamin C — one medium fruit often covers the entire daily requirement. Vitamin C participates in collagen production and acts as a protective substance, but the body does not store it, so it is important to get it regularly. Oranges also provide water and potassium, so they are suitable as a light, hydrating snack.
Is orange juice just as valuable? No — it has less fiber and more sugar per serving, because several fruits are needed for one glass.
Does vitamin C help against colds? It is needed for normal immune system function, but it is not a medicine — do not expect a miracle when ill.
Can you eat oranges with iron-rich food? Yes, food containing vitamin C can help absorb plant-based iron better.
