One of the most common types of kidney stones are composed of calcium oxalate. In addition to calcium oxalate another product is also formed in the formation of kidney stones in the body. Certain foods are high in oxalate and lead to an increase of forming kidney stones in the human body. These high-risk foods are as follows:   Spinach Swiss Chard Almonds (nuts in general) Sesame Seeds Soy Products (such as soy-based milk, cheese, yogurt) Sweet Potatoes Okra Beets Chocolate Black Tea   Another risk factor to developing kidney stones is not drinking enough water. Males have a higher chance than females of developing kidney stones, with the average age being 30. Oxalate in food binds to calcium during digestion in the stomach and intestines and then is excreted in the body as waste. If too much oxalate appears in the urine and not enough liquid (due to not drinking enough water), then calcium oxalate crystals form, which are the kidney stone.  A 35 year old male was taken to the hospital…
