Here's my midwife's recommendations for diet.
4 calcium foods
2 protein (in addition to eggs)
2 green veggies
3 veggies (in addition to the green veggies)
2 grains (these should be whole grains)
1 bean serving
1 iron food
1 vit C source
2 Liters of water
I'm really good at getting my calcium requirements, my eggs and protein, I'm better at the green veggies than I thought but could do better in the veggie department all around, lol... I try to aim for 1 bean dish a day but doesn't always make it... I'm great about getting my fats but refuse to be totally honest about how much fats I intake.. just because I have a very different view from my midwife and don't feel I need to limit healthy fats (butter, olive/coconut oil) and I'm great about my fruit intake... water... I aim for the 2L but generally only make 1 - 1.5L.
