Thanks for the advice on the smoothies.  I will have a look in my local health food shop for such things to add.  Raw honey is amazing, especially mixed in with cinnamon and stuff like ginger and lemon.  I kind of have weird tastes I suppose.  I do like nutty flavours too.  Hemp Seed Oil is rich in Omega 3 and contains a perfect balance of Omega 3:6 for humans, and it has a really great nutty flavour that is nice flavour in a lot of smoothies, and hemp seeds themselves are also great.  If you need calories and enjoy organic peanut butter, a popular choice is to pair it with banana (even though banana is a bit sugary).  But nuts in general are high in nutrients and calories and usually add an earthy flavour to the mix. I've really only just started dabbling in making smoothies, so I'm still getting used to figuring out what works and what doesn't. But I appreciate the suggestions and will definitely give them a go!
