My husband has been concerned that we're not getting enough calcium since switching to a vegetarian (trying to be vegan) diet. What are your thoughts and suggestions?

Calcium is in most whole plant foods, so as long as you're eating a healthy, varied, plant-based diet you should get MORE then enough on a daily basis. Plus, even non-wholesome foods, like soy milk, are fortified with calcium. It would be hard not to get enough unless you just eat junk all day which I know you don't :-) See this link of the world's healthiest foods. Make sure to include those plant-foods listed, like greens. You'll get more than enough. Interestingly, eating dairy actually causes calcium to be leached from your bones, so you'll get more or at least, retain more calcium, by eating plant-based.
