Could someone please tell me if its important to use hex's? The reason I ask is that I'm really finding it really difficult to incorporate them into my meals. I don't drink hot drinks so I rarely buy milk. I love cheese, but I only use it if I'm having something like a baked potato or an omelette. I always have fruit / yoghurt / fry up for breakfast so I don't eat cereals or cereal bars and I rarely buy bread because I'm on my own and always end up throwing most of it out.
