I find that a lot of difference is due to some not taking into account recent research, and of course the ones that listen to the conventional line based on flawed clinical trials. Then they often concentrate on one area of expertise.
I have been trying to understand the metabolic pathways which is not good for my Lyme brain lol!
If you know where to look, the differences are not that big.
So here's something you might not know. A lot of the food preservatives that are banned in the UK, are actually legal in the USA.
A lot of our food isn't traditional health food and even some people with an allergy to wheat are actually able to handle a certain brand of wheat flour made in Ireland.
Not to mention, even our cows are stuffed with soy to fatten them up and lower costs, which in turn, is affecting male hormones because of estrogen.
So, as natural you can eat is best here. It's almost impossible to be perfect, but there's no harm in trying to stick to food that God gave us and not Kelloggs.
I'm sorry to hear about Lyme. I am not very educated on it, to be honest. I really wonder if the mitochondria lady would be a good resource for you.
