Known hazards of Spinacia oleracea:The leaves of most varieties of spinach are high in oxalic acid. Although not toxic, this substance does lock up certain minerals in a meal, especially calcium, making them unavailable to the body. Therefore mineral deficiencies can result from eating too much of any leaf that contains oxalic acid. However, the mineral content of spinach leaves is quite high so the disbenifits are to a large extent outweighed by the benefits. There are also special low-oxalic varieties of spinach that have been developed. Cooking the leaves will also reduce the content of oxalic acid. People with a tendency to rheumatism, arthritis, gout, kidney stones or hyperacidity should take especial caution if including this plant in their diet since it can aggravate their condition.
