Eat the 7 pieces of fruit and veg that they say you should and also eat the amount of dairy you shouldhave in one day also ??

My doctor looked shocked at my appt when i said no because i have so not been able to eat much just the thought of food some days mades me feel yuk.
I do eat some fruit and veg a week but not as much as they say you should.
If all i can eat is a bar of chocolate then that is all i can eat IYKWIM.
