Questions About Specific Health Issues

Type O With Crohn Disease


I was diagnosed with Crohn's disease 7 years ago and had surgery 2 years ago that removed a foot of my small intestine (including the terminal ileum) and a 1/2 foot of the large. I am an O blood type (and currently do not eat red meat, but some fish and a little poultry) and am curious if following your recommendations would help to improve my day to day health. I do not eat dairy currently, but do not otherwise follow this diet now. My general health is ok but do feel sluggish overall and am very able to notice problems with digestion of much of the food I eat. Curious to know your feedback.


Typical O things: wheat, corn and dairy avoidance, the use of the amino sugar n-acetyl glucosamine (not glucosamine sulphate) and the product "Seacure" (a peptide made from whitefish) have been the most successful strategies I've used in my practice. Also, NAP's 'Deflect' products can be very helpful. All of these should be securable from a good pharmacy or health food store.

The Ask Dr. D'Adamo internet advice column ran from 1996 to 2009, at which time Dr. D'Adamo's teaching and programming responsibilities no longer allowed him to devote time and resources to directly answering visitor questions. However we've recently reorganized this treasure-trove of material and made it again available to his readership. He occasionally posts new entries. These are marked with a NEW tag.

When you have your 'cheat' moments on the diet, whether they are intentional treats for yourself or an unexpected slip-up, Deflect can combat the negative lectins that harm your body.
