We already know that BPA has been proven to be very dangerous to human health. Here is another reason to avoid those plastic water bottles and food containers: BPA is now associated with increased risk of miscarriage. PLEASE stop using plastics. Mason jars are my favorite: I use them as my water bottle, tea/coffee mug, and even freeze foods in them. Stainless steel is another option, but I just have this sense that we may someday learn about some hidden metal that is detrimental to our health. As far as grocery shopping goes, try getting your cheese and meat from the deli (less wrapping), bring your own cloth bags for produce (primarily to reduce overall environmental burden), by food with least packaging. Good for our health and good for our environment!
