What to Eat – The Case for both Palio and Vegetarianism

How is it that you can go to a nutrition seminar one week where the speaker is boldly stating that “Everything that you need can be found in the Vegetable Section of the Grocery” and the next is boldly touting that “Meat Based Paleolithic eating is the only appropriate diet”?

I thought red meat caused cancer?  Then how do you explain that certain Eskimos eats up to 10 pounds of meat a day, but there isn’t even a word in their language for cancer or heart disease.

I thought high carbohydrates diet makes you fat? Then how do you explain the native of South America who have lived for generations on a near vegetarian diet?

I thought dairy is bad for you? Then how do you explain the Swiss whose ancestral diet was largely based on dairy and rye?

We are not all cut from the same cloth. Early man ate what was available. These eating habits became eating capabilities and it seems that these capabilities became genetic imperatives. In fact, the distinctions can probably be sorted into distinct eating preferences largely based on genetic coding.

In 1996, the Naturopath Dr. Peter J. D’Adamo published Eat Right For Your Type, where he explains his diet plan based upon blood type.  He asserted that our “blood type is a road map to our inner chemistry—and each blood type processes food, handles stress, and fights disease differently”.

These are his suggestions for eating and exercise according to individual blood types:

blood-typesFor Type O: Focus on higher protein, eliminate grains, and perform energetic aerobic exercise
For Type A: Go vegetarian, exercise more mildly, and ease tension through meditation
For Type B: Vary your diet with a diversity of food groups, and exercise moderately
For Type AB: You have most of the benefits and intolerances of Types A and B



Sympathetic vs. Parasympathetic Dominance controls hormones and influences what kind of protein, calorie intake and exercise our system most efficiently operates.

In the 1980’s Metabolic Typing took D’Adamo’s work a step further.  A researcher named Bill Wolcott introduced food selection criteria based on the speed that each of us oxidizes our food and where we are on a Sympathetic Dominance scale.

Wolcott provides three general metabolic types in his book:

Protein types — Protein types are fast glucose burners and are parasympathetic dominant. They tend to be frequently hungry, crave fatty, salty foods, fail with low-calorie diets, and tend towards fatigue, anxiety, and nervousness. They are often lethargic or feel “wired”, “on edge”, with superficial energy while being tired underneath.

Carbo types — Carbo types are slow oxidizers or sympathetic dominant. They generally have relatively weak appetites, a high tolerance for sweets, problems with weight management, “type A” personalities, and are often dependent on caffeine.

Mixed types — Mixed types are neither fast nor slow oxidizers, and are neither parasympathetic or sympathetic dominant. They generally have average appetites, cravings for sweets and starchy foods, relatively little trouble with weight control, and tend towards fatigue, anxiety, and nervousness. provides some very good information on eating perspectives.

There is no one diet that is right for everyone. There never has been and there never will be a universally healthy diet. The only healthy diet is the one that meets one’s individual requirements.  Eating correctly means that you have fat free energy and guard against degenerative conditions as well. There are few intrinsically good or bad foods, except in terms of foods that are right or wrong for your individual makeup.

Dr. Thomas Santucci’s, DC, CNS Perspective:

typingIt is apparent that even extreme meat or vegetable preferences are correct choices for some people. It is doubtful that going raw vegan is appropriate if you are a Mixed or Palio type. It is equally doubtful that eating all protein works for most people’s genetic coding.

Looking to your own heritage for food selection is a great place to start answering “What should I eat”. Seeking more refined eating choices from works like Metabolic Typing or Eat Right for your Type is a valuable tool to understanding the appropriateness of individual food selection.

These frameworks attempt to give us guidelines based on what we know of our genetic predetermined physiology of metabolism. While genetic markers will undoubtedly continue to improve, the case for biochemical individuality in eating seems valid and explains the diversity of eating preferences.
