Is coffee bad for kidneys?

Moderation is Key
Coffee in moderate amounts is generally not harmful to the kidneys of a healthy 45-year-old male. Aim for about 2-3 cups per day.

Potential Benefits
Some studies suggest coffee might have protective effects on kidney health due to its antioxidant properties.

Considerations
a. Dehydration Risk: Excessive intake can lead to dehydration, as caffeine is a mild diuretic.
b. Existing Conditions: Consult a healthcare provider if there are pre-existing kidney issues or high blood pressure.
c. Cardiovascular Concerns: Be cautious if there are blood pressure or heart rate issues.

General Advice
Stay well-hydrated and maintain a balanced diet for optimal kidney health. Always discuss specific health concerns with your doctor.
