7 Foods You Didn’t Know Are Actually Harming Your Kidneys

3. Caffeine

If you’re someone that can’t function without caffeine, this could be bad news. Studies have found that long-term caffeine consumption can make increase your risk of kidney stones and even worsen chronic kidney disease. This is because of its status as a diuretic, as such foods hinder your kidney’s ability to absorb enough water.

Of course, a single cup of coffee in the morning/evening isn’t a problem, but if you’re prone to consuming caffeine-heavy beverages through the day, you may need to watch out. Caffeine can also increase blood flow, and thereby, blood pressure. But if you do not have any blood pressure issues, a reasonable amount of caffeine shouldn’t affect it.
