If the word calcium conjures up images of milk in your mind, you might find it interesting to know that the highest sources of calcium don’t come from cows or any animal at all. Since calcium is a mineral, it comes from the soil like all other minerals do. One reason milk is thought to be the best source is because originally cows feasted off grass and obtained calcium from the soil. Today, cows are fed cheap sources of soy and corn to help them gain weight quicker, so fortified sources of calcium are actually added to dairy milk following the pasteurization process. Plus, cow's milks isn't the highest source of calcium either. Opt for these plant-based sources of calcium since they're healthier for you and much more delicious too!
