Calcium is important for the structure of bones and teeth. It is important that you absorb a large amount of dietary calcium and want to ensure that it is well absorbed by the body. Calcium absorption can be blocked by a compound called oxalic acid, which naturally occurs in many leaves, including spinach. According to the USDA Nutrient Data Lab, spinach contains 110 g of 0.97 g oxalic acid. Oxalic acid can combine with calcium in the intestine to form oxalate, which is an insoluble salt. These salts can interfere with absorption by making calcium inaccessible to your body. An in vitro study published in the International Food Research Journal investigated the effects of oxalic acid on calcium. Research shows and confirms that oxalic acid decreases the presence of calcium in all salts tested. According to Vegan-health.org, removing water after a pot or boiling spinach can reduce the amount of oxalate consumed.

Because spinach has one of the highest levels of oxalic acid in green vegetables, too much spinach can play a role in the formation of calcium oxalate, which is the most common type of kidney stone. In rare cases, consumption of extreme amounts of oxalate-rich foods such as spinach can cause hyperoxaluria, which is excessive excretion of oxalate by urine. When oxalate crystals in the kidney are combined with calcium, they form stones in the kidney, said the Cedar-Sinai Medical Center. In 2016, a study by the USDA Plant Improvement and Protection Study investigated the possibility of multiplying low oxalate spinach to reduce the adverse effects of oxalate compounds.

Vegetable foods like spinach contain natural purines that your body converts to uric acid. According to FamilyDoctor.org, purines in excessive amounts of spinach can cause health problems for some people who are prone to purine problems, or people with hyperuricemia - excess uric acid in their blood. If you cannot pass uric acid through the kidneys, your uric acid levels can increase. The result is a pile of uric crystals in the joints that cause painful symptoms of gout. Pharmacy Times warns that purine-rich foods such as spinach should not be consumed in very large quantities.

Don't take warfarin anticoagulants in combination with spinach, because vitamin K helps with clotting, which can reduce the effectiveness of warfarin in coagulation control.
