Hi Emma, I am happy you are interested. What I have written is really just a snippet, in fact I almost called it part one - it is a huge topic that expands the more you delve into it. I've never tried Dragon fruit or Durian although the latter rates highly with many raw food experts. You can't really go wrong with any fresh fruit or vegetable that you can eat raw ( eg not white potatoes), as they are unprocessed and the more you consume raw, the more nutrients you will receive.
Herbs are another huge topic really, so for herbal teas if they are good quality ie organic and the best part of them harvested as opposed to some of the tag ends stuffed into many a teabag, they can be a useful drink. I mostly drink filtered water. As for being able to spot good quality in a product - price is a good pointer. If it's cheap compared to the same supplement in a range from a different supplier, than it is likely to be poor quality. At the moment liquid chlorophyll s trending - it's a great natural supplement but the integrity will vary. Hope this helps : )
