Spinach.... hrmmm, doesn't that cause kidney stones and gout:
"...it might be surprising to know that although most foods can be allergenic, spinach is one of the foods most commonly held responsible for an allergic reaction.
Spinach is also classified in the United States as one of the 12 foods in which pesticide residues are most likely to be found. Organic spinach should not present this problem. Oxalates, which can aggravate kidney and gall bladder problems, are also found in spinach, so people with untreated problems in that area should avoid it. It is also worth noting that although spinach does contain calcium, the oxalates also interfere with the body's absorption of the mineral. For anyone taking calcium supplements, several hours should be allowed to elapse before tucking into a meal of spinach.
In addition to the oxalates, spinach also contains purines, which form uric acid and in turn can cause kidney stones and gout. Finally, there are also indications that further substances found in spinach, called goitrogens, could interfere with the function of the thyroid gland. Goitrogens — which impair the uptake of iodine, leading to hypothyroidism— may be rendered inactive by the cooking process, but this has not been established beyond doubt. This means that anyone with thyroid problems can also legitimately say no to spinach.
Nitrates are also commonly found in leafy vegetables, and spinach is no exception. They are found in higher doses in spinach grown in greenhouses and winter spinach generally contains more than the summer type. Spinach picked in the early evening has been shown to have lower levels of nitrates, which decrease once the sunlight has gone. In very high doses, nitrates can lead to blood circulation problems2. In chopped spinach, especially if it is stored in airtight bags or containers, the nitrates can break down to form nitrites. This can lead to methemoglobinemia, where the uptake of oxygen in the blood is adversely affected. In order to avoid these afflictions, spinach should not be reheated once cooked." ( from )
