Dr. Weston A. Price: 11 points

In his World-wide research of PreIndustrialized HEALTHY communities, he found that the peoples had common traits despite the variety and differences in their diets and geography.

1. Extraordinarily high FAT SOLUBLE VITAMINS AND FATS complexes -- meat sources usually organs -- Fermented Cod Liver Oil 2/3 to 1/3 Butter oil and/or Fermented Skate Liver Oil 
2. Bone broth and/or RAW dairy -- GRASS-fed and/or wild -- mineral rich and some fats for absorption. 
3. All Seeds (grains, beans) sprouted, fermented, sourdough  (dormant seeds have phytic acid that holds the minerals trapped and undesirable ratios and potential available minerals until the germ ination conditions to release them along with nutrients, enzymes, etc (phytic acid also grabs onto the minerals from your body.))
4. Seafoods and seaweeds, mostly seaweed. Iodine among 92+ trace minerals and chlorophyll. More "seaweed" algea varieties than "landweeds" -- not to be underestimated. (And salt)
5. Raw foods of all groups, typically about 80% raw to 20% cooked. Not just plants. (Raw yolks have nutrient range and enzymes. Raw whites however have anti-enzymes)
6. Fermented of all of the above. Foods are eaten in season and fermented as living/preserved/raw until next seasons, increased nutrients, enzymes, organisms. 
7. Emphasis that all foods, including dairy (butter, milk, cheese, hard cheese,....) are in season.

I believe these might have been in the original eleven:

1. High enzyme rich. Dehydrated also maintains majority of nutrients and enzymes. 
2. Whole food = WHOLE animal, all parts bones, skin, organs, etc 
3. Huge amount of the plant foods (despite current popular belief, Price did not originally find huge ratios of animal products.
4. Calories almost entirely from FATS. Up to around 80% and mostly from animal sources. 

? These were findings of Price were in "the letter" and are in the site below but doesnt seem like the original list....

1. No processed, industrialized,... no stripped, refined sugars, syrups, flours, chemicals.
2. Preconception diet - minimum of 3 months before conception.
