Does he care or is he going overboard? Keeps annoying me by telling me to eat.?

I really sort of like this guy...I guess though were only in the beginning of a serious relationship. He's into health foods and being active...and he's constantly on me about eating. I eat fruits and veggies abut it never seems to be enough for him. I know he cares and worries a little, probably because I did have a little history of an eating disorder. In a way it shows he cares, but in all honesty its also feeling suffocating. I dont know what to do?
