Annie, sorry to take so long getting back to you. We just got a new puppy and life is rather havocful. I just feel like milk is for babies of the species. I'm not a baby and I'm not a baby cow. It just seems like an odd thing (to me) to drink something produced to help babies grow. That said, I do have some milk, cheese, etc when I want. I'm not strict. I really just prefer the taste, digestibility and logic behind soymilk. I drink Silk which is fortified with calcium, almost the same as milk. Since I have one or two glasses daily, I also take a calcium suppplement. I haven't gotten a bone density test yet, but I've fell on wet rocks in the creek and landed hard on my wrist without breaking it, as well as other falls on cement. Kind of like an unpleasant bone density test? You may need to research a little. It sounds like with your mother's history you may have breast cancer risk in your family. I think there is some thought that more than two servings a day can increase breast cancer risk due to the plant phytoestrogens which have may some hormonal properties. I do think that each person's body is unique and what is best for each is different. So run it by your doctor too.
