I am not sure where you get your information and I would be interested to find out. After carefully reviewing my diet following the death of a few family members from cancer, I have found the only source of information I could trust on nutrition, the only ones that are completely science based, are all recommending the same thing: a whole food, mostly plant based diet. Some of the following doctors actually cure "chronic" diseases with this type of diet. They get results. Some of them get clinical results than can be replicated over and over again. All of them are science based and despite having worked decades the field, fighting multi million dollar lobbies, have never be discredited scientifically. Look it up, it's well worth it:
Dr. Caldwell Esselstyn
Dr. Neil Barnard
T. Colin Campbell
Dr. John A. McDougall
Dr. Michael Greger
Oh, I am sure you will find a few idiots that tried to discredit them, but as soon as you dig, you find the critics to benefit monetarily from the critic, and generally backed by poor science. Some of them (ex. Dr. Michael Greger) clearly have a vegan agenda, but they get the science right, which is more than I can say about the meat/milk/egg lobbies. Who would you rather trust with your health? A health system financed by drug companies that gets a bonus in keeping everyone sick, a bunch of lobbies dedicated to put profits above everything else, including you health, or a bunch of doctors who get results with some of them caring about animal welfare and the state of the planet? I am not a doctor, and I have no knowledge about your health issue, but I can attest that after switching to a mostly whole food plant based diet a year ago, my family and I are feeling much better. I now find that idea that you can only get satiated by meat is bogus, as the real feeling of fullness is directly proportional to the quantity of fibre I ingest.
It is interesting that you mention the morning bacon in your post, as that idea was sold to the US in the 20s by Mr. Edward Bernays, which was at the time a lobbyist for a packing company. I am sure you can trust this guy with your health, his only credential being in public relations and psychology. He managed to get some doctors of his times to say that a heavy breakfast was better that a light breakfast, an then used that to promote bacon in the morning ...
