Many factors will have to be taken into consideration when you decide to become healthy again and sometimes that 'again' means from early birth. The very things that many of us had done to us and had forced into our bodies as children in the name of good health are the very things that are causing us to die early in great ill health. Thankfully, ideas are starting to change with regard to early childhood food and health but much damage has already been done and it will take some doing to reverse the effects of ignorant parents. Not necessarily their fault, they were told how to feed us and poke us with needles and disinfect us etc, by over zealous doctors and university graduates who totally disregarded the natural instinct of natural mothers. Nowadays it is still the parents who are to blame for our children's ill health.
Many parents now know pretty well what is good or bad to eat even if on a very base level.
By that I mean that most people now realise that, for instance, sugar is not good or rather 'too much sugar'. It should be just 'sugar is not good' but most stay with the TV ads which tell us that sugar is natural. Or that is not good to eat 'too much junk food' etc. I say that it is still the parent's fault because in most cases television is to blame for much of the ill health of our children and it is we who allow them to watch channels which continually bombard tiny brains with information about junk food, lolly water and 'good tasting food'. The only reason that many of the big corporations are swinging around to semi-healthy foods is that they see a buck in it.
