over the many years we've had this discussion those of us with adopted kids tend to feel that nature has a bigger influence than originally thought. We are together for the holidays. Breakfast today. We are all eating what we would like. Me: kale and spinach juice Husband: egg and coffee Son (bio) : Protein shake with a banana Daughter (adopted): large pizza and giant fancy coffee from McDonald's. She eats differently than us. Ok. I did read a fascinating study that what a mother eats while pregnant can often influence the tastes of the child . So if mom ate a lot of pizza while pregnant, maybe her unborn baby will crave pizza. I don't know. Our daughter is an adult and she has ZERO interest in ANY of our desires to eat healthy. She does however REALLY like it when we make a traditional sweet food for a holiday. She likes traditions which is lovely. But it is interesting that NONE of our other food ideas like avoiding heavy foods or trying to eat vegetables etc has influenced her even a little. She is obese and I'm worried. I've considered by pass surgery, but I understand those can be ruined if the person doesn't follow the rules. I've offered to pay for WW...she has little to no interest.
