Amadio While it's true that there has been a rise in many degenerative diseases in the past 60 years, the simplistic message given by this film is wrong. Eating animal fats does not cause, for example, heart disease. Look at the Inuit, whose diet is traditionally 90% seal fat. Or the Masai, whose diet is traditionally 90% meat, milk and blood. This film does raise awareness of the need to change the Western diet, but animal fat and protein are not the culprits. A high fat, lo-carb diet works well. As does a lo-fat, high carb diet. But you can't have both hi-fat and hi-carb. Corn syrup and sugar in everything, additives and preservatives are the dangers. Not fats and a little protein.

efrosean Using misinformation, bad science and conspiracy theories this film is just bunkum. One of the problems with documentaries of this ilk is the low level of scientific knowledge that the general population has, when presented with material pretending to be science most people will just accept it as fact. This is especially the case in areas where the public can be misinformed for profit or influence, the vegan agenda is the influence here. I have no problem with someone who is or wants to be vegan, go ahead. However, to justify your choice and convince others of the validity of your choice don't feed me BS. Unfortunately that is what this film boils down to a lot of BS. The work of T.Colin Campbell, upon which a lot of this film is based, has been re-examined and been found to be extremely lacking in rigour. Have a look here for a very good critique of Campbell's work.http://www.cholesterol-and-health.com/China-Study.html

mre21 I have mixed emotions about this film. I like the message that Americans (actually most of the world thanks to the spread of fast food chains) is becoming less healthy and more obese. However, despite what 'bhouman' the alleged surgeon on this site wrote, there are many seemingly deliberate inaccuracies in this film. Here are just a few:* Prostate cancer is not the leading cause of cancer in men. It is skin cancer (http://www.cdc.gov/features/cancerandmen/). * There is a risk in having a plant based diet in that there are nine amino acids our bodies cannot produce and, while these are found in meat, they only exist in certain plants. This was the argument of the director of nutrition at Wash U. but it was dismissed with a response that has nothing to do with the quality (types of amino acids present) of protein: "eating whole foods it is virtually impossible to be protein deficient without being calorie deficient because even if you take the foods that have the least amount of protein in it, lets say potatoes or rice – eight, nine percent. That's the figure we more or less need."* The film claims that milk causes metabolic acidosis which in turn leads to lower levels of stored calcium in bones. The explanation given is that milk lowers blood pH and calcium is taken from bones in order to form calcium carbonate and thus help neutralize the blood. The truth is that sodium bicarbonate is used to neutralize blood pH and although milk is slightly acidic, it is nowhere near as acidic as the stomach itself. Metabolic acidosis is typically related to kidney or liver failure or in an uncontrolled type 1 diabetic reaction (DKA). This whole explanation about milk in the movie is ridiculous and feels manufactured to scare people away from drinking milk. * A claim is made that Americans drink energy drinks, caffeine, and sugar because they have chronic fatigue. Okay? Based on what evidence? None is given, but this sets the stage for arguing for spinach which typically provides some sense of energy.* The whole argument about the USDA conspiring with the meat and dairy constituents of the government to falsify dietary recommendations to the American people is just paranoid speculation which is completely unsubstantiated in this film.Most of the rest of the film has some great points that are true.

tawna-brown I believe that the two most important indicators of good health are your BWI and your level of activity. You can't compare people who have good BWI and a good level of activity with people who do not and just compare their diets. These factors BMI and activity level, would have to be the same when you make comparisons of diets or you're creating more hype than science.Both bone cancer and arthritis have been found in many dinosaur bones. These diseases have been around forever. Insects have survived much longer than almost any other species. Maybe they should be studied. I'm sure they eat on instinct. If we can get our natural instincts to crave the healthy foods, maybe then we would have something that could help everyone.
