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

1. Nuts

Nuts are healthy, of course, but not if you are someone who is prone to kidney stones. This is because of a category of minerals called oxalates that can be found in the most common type of kidney stones.
And it’s not just nuts. Other foods containing oxalates, such as spinach, beets, French fries, bran flakes, and potato chips are best avoided if you’ve ever had kidney stones in the past. Even “healthy” people need to moderate their intake of such foods. And as always, eating a variety of green vegetables and healthy foods is better than sticking to just one.
