This is a follow-up to my 1 November 2010 blog, "BTD or GTD?"
Then and there, I wrote, "The jury's still out."
Well: It's back.

For this gal, it's BTD all the way.

Nor did I ever get with the SWAMI program (the computer program for individualizing one's plan according to Dr. D'Adamo's post-Blood Type research).

Back in 1996-97, I was excited - nay, galvanized - by D'Adamo's bloodtype teaching. His 1996 groundbreaking book,Eat Right 4 Your Type, is still a best-seller - Number 212 in sales at Amazon, almost 15 years post-initial publication! - for a reason. It resonates, and works, for millions of us.

It's more than diet: It's thinking. It's a cohesive way of seeing human life, gene-groups and migrations. I've always found the Genotype classifications to be hazier. On D'Adamo's website's forum, Genotype-SWAMI adherents admit that their classifications keep changing, over time, with all sorts of variable conditions. It's a program that defies group classification, and that's fine - even preferable - for many who desire to keep monitoring those factors.

Even the title of Dr. D'Adamo's last book has changed - from The Genotype Diet (the one I bought in 2008) to Change Your Genetic Destiny. While Dr. D'Adamo is of course not claiming to be able to alter anyone's genes, he is linking diet to the possibility of facilitating or hindering susceptibilities to illness and "premature" aging that are genetically sourced. There are those who enjoy learning and knowing about glycation and methylation, but nowhere near as many as believe the Blood Type model appropriate for their needs.

Eat Right 4 Your Type is readable and understandable - and followed - by people all over the world. It isn't for lack of grey matter that I am more comfortable with it than with the mutable computer program. Among bloggers at D'Adamo's site, I can be counted on to espouse, promote, and guide in Dr. D'Adamo's Bloodtype teachings, with the occasional foray into the Genotype diet, perhaps just to mention my use of or reaction to a component of the "Nomad" program from time to time.

The ER4YT/LR4YT bloodtype system stood me in good stead for nine years before I became a blogger here, and continued after I bought The Genotype Diet two and a half years later.

I still assist newcomers to Dr. D'Adamo's bloodtype work. And the beat goes on.
