Cow's milk is a food of choice in a healthy diet because it is a reliable source of 15 nutrients, including complete protein. In contrast, the nutritional value of plant-based beverages can vary substantially from one brand and variety to the next. Most fortified plant-based beverages have significantly less protein per serving than cow’s milk. In addition, the calcium naturally present in cow’s milk is often better absorbed by our body than what’s added to fortified plant-based beverages. Some research also shows that up to 40% of the calcium added to plant-based beverages can stick to the bottom of the container even if it is shaken vigorously.
