Hi, I just started the blood type diet and am A Positive.  The book states I can have corn of any kind, however my husband says corn has gluten in it.  This diet only says I cannot have wheat which is definitely gluten.  
My husbands concern is that the book might not have the updated information stating corn is a gluten
Any information on this topic would be greatly appreciated.
Thank you!

  if genetically modified, which in fact is not advised by Dr D, I might agree with your h.

Try the genetic destiny book and swami for top of the line updated information

You're husband is right corn does contain gluten however this is a very different gluten than the one found in wheat. When Dr D. refers to gluten he intends to refer to the type found in wheat, rye, etc.

Here's a good informative post: http://www.celiac.com/articles/8/1/What-is-gluten-What-is-gliadin/Page1.html

Do you have a gluten sensitivity that you are aware of? If you are not gluten sensitive or a non-secretor, there's no reason for you to avoid it.

Welcome

All grains have proteins in them; but corn does not contain the kind of gluten that's problematic for individuals with Celiac Disease, or for most people on gluten-free diets.

However, not all individuals need to avoid gluten. While most blood types need to avoid wheat, spelt, rye, and/or barley is acceptable for many blood types, and those grains all contain gluten.

Gluten is only one protein found in foods; many foods are considered "best avoided" due to lectins or other chemicals naturally found in the foods. The Blood Type Diet is far more complex than "a gluten free diet" and not as easily explained. Dr D's newer works are even more complex.

Eat Right 4 Your Type explains the basic  blood type diet (BTD). Live Right 4 Your Type, along with all the BTD books that follow, the apps, and the typebase on this website,  list the different food lists for secretors and non-secretors (making 8 diets, not 4.) Genotype Diet (GTD) lists 6 different diets, of which blood type is one factor in determining your "type" but not the only factor. The most recent diet is SWAMI, a computer-generated diet that computes the "perfect diet" for each individual, combining blood type and genotype factors.

All the diets Dr D developed are wonderful diets; there's no need to rush to get GTD or SWAMI if you're already feeling overwhelmed implementing BTD.

The determining factor for whether As can or cannot have corn is not the presence of corn gluten, but whether the person eating the corn is a secretor or nonsecretor.

An A secretor can eat corn as long as they do not have an allergy to or experience other adverse reactions when eating corn.

An A nonsecretor should not eat corn or any food product containing ingredients derived from corn.

Please research GMO and organic and corn.

I never eat corn, corn syrup, corn starch, etc. however, I do sometimes eat fresh homemade corn tortillas from our friends local Mexican restaurant. They use organic masa. It is so seldom, but I don't knowingly suffer in any way from eating them.
Perhaps because I am an A secretor?

Corn is a black dot for me and I avoid it whenever possible, though I don't seem to react to masa, or even corn kernels, if I don't indulge often.

Corn is more of an insulin issue (not something nonnies want to play around with too much). For BT O, B, and AB it is a lectin (protein) issue. The reactions of a Type A are more likely to be upset blood sugar which can resemble any other sort of problem you may have experience with.

It occurred to me today that much of the issue with corn today may be because of it's GMO status...

I agre, with Drea and  also on the insulin issue , may be seldom for As sec.is not so bad , if organic only
