Husband controls what I eat

My husband eats very healthy & simple, no fried & spicy food, sometimes even tasteless. I prefer food with more taste. I am 17weeks pregnant, at times I crave for junk food like McDonald's , potato chips, spicy food etc. Husband will nag & stop me from eating. I understand the need of being healthy for the sake of baby but its my craving and I don't eat it everyday. How can I make my husband not to control me? I tried talking to him nicely but it didn't work.
