I tried keeping track of my calcium yesterday, and to be honest, if I didn't take the supplement, I would fail miserably this week. None of my foods have labels that list calcium, and figuring it out seems impossible. I have muesli that is a mix out of three different kinds of mueslis, and I would have no clue how to find out what the calcium content of those is. My yoghurt doesn't list it, and after 15 minutes of searching the net for info, I hadn't found any kind of yoghurt with similar stats which listed calcium. Same with any self made food in various portion sizes. Fruit and whatnot is straight forward, but anything beyond that seems to be a major pain in the behind, with either no, or conflicting information on the net. :/
