Dr. H. L. Newbold on Ground Meat


I consider Dr. H. L. Newbold to be one of the great medical mind of the last century. To learn more about him, please read my page H. L. Newbold.

This is an excerpt from the above pictured book. I do not recommend buying this book, as it was a precursor to his later and better volume The Type A / Type B Weight Loss Diet.  Nevertheless, he does share some interesting ideas and observations in this older book, as quoted below.

Dr. H. L. Newbold:

Do not eat ground meat. I know hamburgers are right up there with motherhood, milk, and the American flag, but we must face facts. Patients in my practice to not feel good after eating ground meat. Off-hand, it does not make sense that patients seem able to eat steak and not react to it, but have a reaction to ground beef. Still, I have checked my observations on hundreds of patients and must stand firm on what I have seen.

I don’t know why, but…my theory deals with rapidity of absorption. If you eat foods that still are relatively bulky, even after chewing (like steak), then the digestive enzymes must work on them a long time before they are broken down enough to pass through the intestinal walls into the bloodstream.

On the other hand, ground meat is rapidly digested and rapidly enters the bloodstream. We know that if you have a mild allergy to food, you will get a much stronger allergic reaction if that food is quickly digested and passed on into the system. Some people who have a mild allergy to beef do not react to steak (slow absorption), but do react to the ground beef (quick absorption). Patients are also more likely to react to other forms of commercially-ground meats, such as lamb, for example.


I do not think this is an issue for everyone, but it is certainly good to be aware of the possibility. Most long term practitioners of Zero Carb appear to do just fine with ground beef. However, Samantha Taylor – who has followed an all meat diet for over 5 years now – has reported experiencing symptoms of irritable bowel syndrome (IBS) every time she eats ground beef. So, as always, the best thing to do is experiment and see if you notice any difference in the way your own body responds to whole meat verses ground meat and then do whatever feels best to you.

Another thing to keep in mind is that for people with histamine intolerance, ground meat is much higher in histamines. Once meat is ground, histamines form much more quickly. So, if you do have histamine issues, it is important to have the meat ground fresh and then get it into the freezer as quickly as possible to stop histamine formation.
