Wheat
Einkorn, an old wheat strain: 14 chromosomes. Modern wheat: 42 chromosomes, plus artifically increased loads of plant-inherent pesticides an d phytines. Go figure why people react with bowel problems, autoimmune and chronic desease to it. Our guts simply is not made to digest this, and it still has not figuredout how todo it. Will take us some more tens if not hundreds of thousands of years.
The to-go-to book on grain and wheat deseases is this. The author teached in Mainz and Harvard, runs wordwide uniqpe special ambulance for just these in both places, and is seen as one of the globally leding top experts on the matter. For laymen the book is a bit demanding at times, but it can be done, also, it does not compare to a Tolstoi novel in size. I read it two times in a row, however, to complete my understanding of it.
