USDA.gov has removed their Food Composition Database through which you were able to search for list of foods high in particular nutrient, such as potassium, vitamin C, etc., and their new [Food Data Central][1] does not enable that. I know that NutritionData has [Nutrients in Food Tool][2], but I'm missing search per serving and search through shortened (not full) lists. So, does anyone know for another useful database?
