I own the book. I would recommend purchasing it to look at the pictures and read the captions if nothing else. It was written by a Canadian dentist who, along with his wife, traveled the world in the early 20th century and visited the few remaining communities that only ate their native diet of whole natural foods. The book is filled with amazing pictures of people with beautiful teeth and skin and along with people whose bodies have been destroyed by modern eating. There are also pictures of deformed malnourished animals.
Nutrition and Physical Degeneration, along with a ton of research, helped me figure out that there is no such thing as chronic disease, only malnutrition. Arthritis, diabetes, heart disease, and many cancers are caused by the foods we eat and the nutrients that we lack.
I haven't read the book in years, but there is information in proper nutrition. I looked in the index and vitamin k is not mentioned. Dr. Weston Price said if you drink milk, drink it alone as a meal itself, which makes sense because milk has protein, carbs, and fat. He meant raw milk and I personally stopped drinking milk when I noticed that organic milk lasted for a month. Food has to rot quickly, so no pasteurized or homogenized milk.
