Foods To Avoid For Optimal Kidney Health

71. Artificial Sweeteners and Food Dyes

While artificial sweeteners like aspartame and sucralose are often used as sugar substitutes, some studies suggest a link between their long-term use and a decline in kidney function. Similarly, certain food dyes, particularly those found in brightly colored processed foods and drinks, can put an additional strain on the kidneys as they work to filter these synthetic compounds out of the bloodstream. Opting for natural flavors and colors is a safer choice to reduce your kidneys' workload.

72. High-Oxalate Vegetables

We've mentioned kidney stones and oxalates, but what about all the foods that contain them? While some are generally healthy, a high intake can be risky for people prone to kidney stones. Besides rhubarb, which you've already included, other high-oxalate culprits include spinach, beets, and nuts. For those with a history of calcium oxalate stones, limiting these foods is crucial to prevent the painful formation of new stones.
