Can coffee be considered water intake as well?

While coffee does contain water, it should not be considered a primary source of water intake. Although caffeinated beverages do contribute fluid to the body, the caffeine content may act as a diuretic, increasing urine output and potentially leading to dehydration.

Plain water remains the best choice for hydration. It is absorbed quickly by the body and does not contain any substances that could interfere with the body's fluid balance.
