I am the only Paleo eater in my house. I am also the primary cook and grocery shopper. The likelihood of my family switching to my way of eating is slim to none. My husband is a "meat and potatoes" kind of person and thinks my food is weird. I don't have issues with having the bad food in my house. I've learned to control my eating and don't expect everyone to eat what I eat.
The question came up this weekend, while I did my Holiday Baking for friends and family. Despite the fact that I would not eat this type of food, I made cookies and caramel corn and toffee for my co-workers and family. It's a holiday tradition and they would be disappointed without it. I feel almost like I am poisoning them though, even if they are happy about it.
I think next year I may have to come up with some new gift ideas.
