It's the kind of question that our mothers harass us with. When we voice our answer, doctors stare at us disapprovingly. This is also the reason we avoid dietitians, or outright lie to nurses and grandmothers. When you're old, you won't want to move much anyway, right? What am I talking about? Calcium! It's National Osteoporosis Day, so in the spirit I calculated yesterday's calcium intake: Almost Zero (you know, if you count a piece of cake or 2 miscellaneous eggs). As much as I'd like to ignore this and pretend I get plenty of calcium, I don't want to have a hunchback at 60 years old. My great aunt is 90 and still travels the world! Talk about inspiring. So how do you get more calcium? And not just in your diet - how do you make sure it gets into your bones and stays there, after you're old and prone to falling from natural declines in your sense of balance? I'll give you a hint: dairy doesn't make your bones any less frail. So what are good sources of calcium, then? Click the link, or read on: leafy greens (especially kale), nuts (almonds!), seeds, soy, and white beans. See Whole Food's list for more ideas. Exercise is also great for strengthening bones, but it needs to be weight-bearing, like these workout ideas (floating in the pool doesn't count). Try yoga, running, or dancing! Do you have any favorite workouts or calcium-rich recipes?
