The Power of Ancestral Diets

Weston A. Price was a pioneering dentist and researcher in the early 20th century whose work significantly influenced our understanding of nutrition and health. Price’s concern with declining dental health among his patients led him to investigate the dietary habits of various indigenous populations around the world. His research aimed to understand why these groups, with their traditional diets, exhibited exceptional dental health and overall vitality.

Price traveled extensively to remote regions in Africa, the South Pacific, and the Swiss Alps, documenting the traditional diets of these populations. His findings, detailed in his influential book Nutrition and Physical Degeneration, revealed a striking contrast between the health of people consuming nutrient-dense traditional diets and those who had adopted modern, refined foods. Price observed that the shift from traditional diets to those high in sugars and processed foods led to a rapid decline in health, including significant dental issues, facial deformities, and increased disease incidence—often within just one generation.

A key aspect of Price’s research was his identification of the critical role played by fat-soluble vitamins, such as A, D, and K2, which were abundant in traditional diets but often missing from modern, processed foods. He demonstrated that these nutrients were essential for maintaining dental health and overall well-being. Price’s work has had a lasting impact on the field of nutrition, highlighting the importance of whole, nutrient-rich foods for supporting both oral health and general health.

Health Issues: Ancestral vs. Modern Diets

  1. Dental Decay and Periodontal Disease: Price noted a stark contrast in dental health between ancestral and modern diets. Populations consuming ancestral diets exhibited nearly no dental decay or periodontal disease. In sharp contrast, those on modern diets faced widespread issues with cavities, gum disease, and overall poor dental health. This discrepancy was largely attributed to the nutrient deficiencies prevalent in modern diets, which lack the essential vitamins and minerals necessary for maintaining healthy teeth and gums.
  2. Facial and Skeletal Development: The research highlighted severe impacts on facial and skeletal development associated with modern diets. While ancestral diets supported well-formed jaws and straight teeth, modern diets were linked to malocclusion (crooked teeth) and underdeveloped facial structures. These problems were attributed to the lack of critical nutrients in modern diets, which impeded proper growth and development.

3. Increased Chronic Diseases: Populations on modern diets exhibited a rise in chronic diseases, including arthritis, diabetes, and heart disease. These conditions were less prevalent among those consuming ancestral diets.
4. Compromised Immune Function: Modern diets were associated with weakened immune systems, leading to higher incidences of infections and illnesses. In contrast, the robust immune health observed in populations following ancestral diets was attributed to their high intake of fat-soluble vitamins and nutrient-dense foods.
5. Digestive Issues: Price’s observations also noted that modern diets, often low in essential nutrients and high in processed foods, were linked to increased digestive problems, including constipation and gastrointestinal distress. Ancestral diets, rich in whole foods and diverse nutrients, contributed to better digestive health and fewer gastrointestinal issues.

Characteristics of Traditional Diets – 11 Principles

Based on his observations, Price identified several principles that characterized traditional diets:

  1. No Refined Foods: Traditional diets excluded refined or denatured foods, such as refined sugars, white flour, and hydrogenated oils. These foods were replaced with whole, nutrient-dense alternatives.
  2. Animal Foods: A diverse range of animal foods was consumed, including fish, shellfish, fowl, mammals, eggs, and milk products. The whole animal was used, with a focus on organ meats and fats.
  3. High Nutrient Density: Traditional diets contained at least four times the minerals and water-soluble vitamins, and ten times the fat-soluble vitamins (A, D, and K2) found in animal fats compared to modern diets.
  4. Raw and Cooked Foods: Some animal foods were consumed raw, while others were cooked. This combination preserved essential nutrients and enzymes.

5. Enzymes and Beneficial Bacteria: Traditional diets included enzyme-rich and lacto-fermented foods, which provided beneficial bacteria and supported digestive health.
6. Prepared Seeds and Grains: Seeds, grains, and nuts were soaked, sprouted, or fermented to neutralize anti-nutrients and improve nutrient absorption.
7. Balanced Fats: Traditional diets contained a balance of saturated and monounsaturated fats, with minimal polyunsaturated oils.
8. Omega Fatty Acids: An almost equal ratio of omega-6 to omega-3 fatty acids was maintained.
9. Salt Usage: Salt was included in traditional diets, contributing to overall health.
10. Bone Broths: Animal bones were used to make gelatin-rich bone broths, which provided important nutrients.
11. Nutrient-Rich Foods for Future Generations: Special nutrient-dense foods were provided for parents-to-be, pregnant women, and growing children. This ensured proper development and health for future generations.

Dietary Guidelines

To align with the principles of traditional diets, the Weston A. Price Foundation recommends:

  • Whole, Unprocessed Foods: Focus on whole, unprocessed foods for optimal health.
  • Animal Products: Incorporate pasture-fed beef, lamb, organ meats, poultry, eggs, and wild fish.
  • Full-Fat Dairy: Choose full-fat, raw, or fermented dairy products from pasture-fed cows.
  • Traditional Fats: Use animal fats and traditional vegetable oils, such as extra virgin olive oil and coconut oil.
  • Cod Liver Oil: Regularly take cod liver oil to ensure adequate intake of vitamins A and D.
  • Fresh Produce: Consume organic fruits and vegetables, and include them in various meals.
  • Prepared Grains and Legumes: Use properly prepared whole grains, legumes, and nuts.
  • Fermented Foods: Incorporate enzyme-rich lacto-fermented vegetables and condiments.
  • Bone Broths: Make homemade stocks from pastured and wild sources.
  • Filtered Water: Use filtered water for cooking and drinking.
  • Natural Seasonings: Season foods with unrefined salt, herbs, and spices.
  • Homemade Dressings: Prepare your own salad dressings with raw vinegar and quality oils.
  • Traditional Sweeteners: Use traditional sweeteners like raw honey and maple syrup in moderation.
  • Moderation with Alcohol: Consume unpasteurized wine or beer in moderation.
  • Safe Cookware: Use stainless steel, cast iron, or glass cookware.
  • Natural Supplements: Opt for food-based supplements.
  • Lifestyle Factors: Prioritize sleep, exercise, natural light, and positive thinking.

Dietary Dangers

Avoid the following:

  • Ultra Processed Foods: Such as cookies, cakes, and packaged sauces.
  • Refined Sweeteners: Including sugar, high fructose corn syrup, and fruit juices.
  • Refined Grains: White flour and white rice.
  • Hydrogenated Oils: Avoid hydrogenated and industrial polyunsaturated oils.
  • Veganism: Avoid vegan diets that lack essential nutrients found in animal products.
  • Protein Powders: Often contain harmful ingredients.
  • Processed Dairy: Such as ultrapasteurized milk and imitation dairy products.
  • Factory-Farmed Animal Products: Including eggs, meats, and fish.
  • Highly Processed Meats: Like lunch meats and sausages.
  • Improperly Prepared Nuts and Seeds: Which can hinder mineral absorption.
  • Canned and GMO Foods: Avoid genetically modified and processed fruits and vegetables.
  • Artificial Additives: Avoid MSG, artificial sweeteners, and other additives.
  • Fluoridated Water: Avoid drinking fluoridated water.
  • Synthetic Vitamins: Steer clear of synthetic supplements.
  • Microwave Ovens: Avoid using microwaves for cooking.

Dr. Weston A. Price’s research provides compelling evidence of the profound impact of diet on health. His comparative analysis of traditional and modern eating practices highlights the importance of nutrient-dense, whole foods in maintaining dental health and overall well-being. By embracing dietary principles similar to those of traditional cultures, individuals can support optimal health and prevent many of the health issues associated with modern eating habits.
