At the end of the day it comes down to individual choice. I don't see my choices as a "diet" but the way I now live. It is different to before but I have read a lot and I am sure it will keep evolving for me. The information can be so conflicting. As your father said Chemostyle - who knows why some bodies adapt and others don't. What we eat is only one way of impacting our bodies but we can control it perhaps more than some environmental influences.
Moderation means different things to different people which is perhaps why recommending extremes are popular - if extreme is recommended then maybe someone will make a few changes that are beneficial.
Regarding soy and flax - there seems to be controversy everywhere about these and oestrogen. My belief is that the closer to natural the better - so soy or flax in any sort of processed form is possibly harmful - powders in particular. I use flax oil daily and soy as my preferred milk substitute (I prefer Bonsoy as there are no added nasties) though I often mix it up with almond or rice milk. I am quite comfortable with the small amounts of soy that I consume and also adding Flaxseed oil (cold pressed and organic) to my diet daily.
There is also controvery regarding coconut oil - I am leaning toward it being ok in moderation rather than excluding it from my diet because of it's saturated fat content - anyone else have thoughts on this?
At the end of the day - food can be medicine and it can be wonderful providing our bodies with amazing nutrition. That's worth celebrating.
