I'm nursing right now as well. In my experience eating well can only help breastfeeding because your body is healthier and you feel so much better (and I find I sleep better too). If making big changes is too hard, you could always just slowly add a few more healthy foods to your diet and you won't have room for as much junk food. And then just keep adding a few more healthy foods each week. Or take away one junk food, like replacing pop or iced tea with water. Also lots of water can only help nursing as well. Whatever way you do it, good luck!

I would suggest getting the book Eat For Health it is a gentler approach to becoming a nutritarian.

I am with you 3000 calories is too many. I would gain weight with that many calories while breast feeding.

Eating this way will make you feel better and prevent disease. All the new studies coming out state that if we let our children eat an unhealthy diet it increase the odds that that child will get cancer and other diseases when they are older. One fun fact I learned these past couple of weeks: when we cook starchy food such as white potatoes in the oven or fried it create acrylamides during the cooking process. French fries were at the top of the list containing the most acrylamide after cooking. Acrylamides are a know carcinogen. https://en.wikipedia.org/wiki/Acrylamide

Anyway, what better way to help ensure your child may grow up with less disease then start with a healthy diet while breastfeeding.
