Another common type of kidney stone is a uric acid stone. Red meat and shellfish have high concentrations of a natural chemical compound known as a purine. High purine intake leads to a higher production of uric acid which then accumulates as crystals in the joints, or as stones in the kidneys.
Pasta, chives and other low-oxalate foods can guard against kidney stones. Oxalate is a compound found in many foods and produced by your body. While harmless for most people, high oxalate levels can trigger or worsen kidney stones -- an often painful condition in which pebble-like deposits form in your urinary tract.
