Oxalis debilis

Oxalis debilis er jurt af smæruættkvísl sem er upprunnin frá Mið og Suður-Ameríku (suður til suður Brasilíu), en hefur breiðst út víða um heim. Tegundin er notuð til matar og eru allir hlutar nýtanlegir; blöð, blóm og rótarhnýði. Menn hafa hafa talið að mikil neysla á henni geti valdið kalkskorti vegna oxalsýru, en rannsóknir sýna að þær áhyggjur eru ofmetnar.http://dietary-supplements.info.nih.gov/factsheets/calcium.asp  "Other components in food: phytic acid and oxalic acid, found naturally in some plants, bind to calcium and can inhibit its absorption. Foods with high levels of oxalic acid include spinach, collard greens, sweet potatoes, rhubarb, and beans. Among the foods high in phytic acid are fiber-containing whole-grain products and wheat bran, beans, seeds, nuts, and soy isolates. The extent to which these compounds affect calcium absorption varies. Research shows, for example, that eating spinach and milk at the same time reduces absorption of the calcium in milk. In contrast, wheat products (with the exception of wheat bran) do not appear to have a negative impact on calcium absorption. For people who eat a variety of foods, these interactions probably have little or no nutritional consequence and, furthermore, are accounted for in the overall calcium DRIs, which take absorption into account."
