Here is a short video (6 min) describing the Pottenger cat study and also Dr Weston Price. It is very interesting how the two correlate and support each other. They also demonstrate clearly that it is natural foods that are mostly raw that are important to health, not necessarily the types of diet. Natural foods are fruit, vegetables and meats. They are not the sugars, refined foods, cereal grains and genetically modified foods that our society is inundated with these days.
