I was reading the post about mothers who are capable of breastfeeding not being entitled to formula. So it got me thinking about mothers who may be physically capable of breastfeeding but eat an unhealthy diet of processed foods or drink or smoke, etc. With so many people overweight, eating processed foods, doing recreational drugs as well as social drinking, I would imagine that not every breastfeeding mother is completely pristine in her eating/drinking habits. Heck, the only way to know what is really in your food is to grow it yourself and how many mothers actually do that? Wouldn't that make formula better for the baby in some cases? How do you prove that the breastmilk given to baby is of the highest quality? What are your thoughts on this?
