Hippocrates said 2500 years ago, "all disease starts in the gut". He did not know what we know now and that is that 80%, at least, of immune function is in the gut. The significance of all this is that our foods are making us sick. The manufactured foods. The unnatural foods ( ones that did not exist for us in our history). I will also add all those additives really do effect your microbiome and therefore your health and mood.
I could go on here for a long time detailing this, but as the ancients said, a picture is worth a thousand words. This is a video. Realize as your watch this, modern food is as addictive as cocaine or smoking, if not more so. So any changes that you make are ultimately up to you. Just remember as you eat you are telling those around you, what you are eating is ok and the video you are going to watch is not important. Children learn by example.
Change comes slowly. i read the other day that after a scientific medical fact is proven it takes 17 years to reach mainstream medicine....I can not wait. How about you?
