I would be careful with nutritional advice given from the Weston A. Price foundation. They have recently taken money and become more of a lobbying arm for the meat and dairy industry. If you look at Dr. Weston's original research (which I agree with), he found that out of all the indigenous tribes/peoples he observed around the globe, only one utilized milk. His initial assumptions were that most would utilize milk/dairy from pasture raised animals which obviously from his conclusions proved to be way off the mark. He was also shocked to find these people with amazing hygiene and dental health. Even today, some ethnic groups can't tolerate dairy at all because they lack the sufficient enzymes to break down lactose. Northern Europeans were also like this at one point, but over time our bodies adjusted and adapted to accept dairy (though it was raw and organic!) Dairy still remains to be one of the most common allergen/sensitivities for many people.
With that said, dairy in my opinion has done much more harm than good; especially in its current poisonous PASTEURIZED form. The irony today is that while pasteurization of foods/beverages was supposed to insure a safe food supply for the masses, it may end up doing much more harm than good (I think we are seeing the proof of this today). It essentially denatures good enzymes and naturally occurring compounds in these foods. That's why with such things as milk or juices, they have to fortify it with vitamins. I think the biggest culprits leading to bad health today are all the refined grains, sugar, dairy products, and the long list of unnatural chemicals they put in processed foods.
I think a diet that contains mostly raw foods is one that would be most beneficial. A whole foods based diet which includes generous amounts of fruits, veggies, (especially dark leafy greens!); with healthy extra virgin oils, nuts, seeds, and organic meat (the more raw the better!) in moderation and balance. Use spices and lots of fresh herbs such as parsley, cilantro, basil, sage, rosemary, tarragon, mint, thyme etc... These are EXTREMELY healthy for you and chalked full of nutrition. Substitute cows milk for hemp or almond milk. Make a green smoothie everyday to get your day started which contains essential amino acids, nutrients, vitamins and enzymes. Substitute healthy teas in place of coffee or energy drinks. Use RAW organic unpasteurized locally grown honey or stevia instead of sugar if need be. Get's lots of fresh air and sunlight everyday. This will provide sufficient vitamin D which your body needs, which in turn bolsters your immunity and endocrine functions. Also, stay away from extreme diets such as Atkins or any that advocate removing whole natural food groups!
