@izzythepush,
You are correct Izzy, it is healthy to be optimistic and skeptical about scientists and their ideas, I'm with you on that one.
But I have wikipedia search 82yr old Dr T. Colin Campbell to see if he's a genuine and honest individual, or if there are any loopholes or hidden agendas in his profile. So far I haven't found anything to nail him on. He seems like a very sincere and professional scientist. At 22yrs of age he got his Bachelor of Science in pre-veterinary medicine, at 24yrs of age he got his Master of Science degree in nutrition, biochemistry and at the age of 27 he got his Phd in biochemistry, nutrition and microbiology. In his career he's also done extensive biochemical scientific research with the American government and the United Nations. He has written best-selling books on biochemistry.
But you think I need to do more research on this guy? fair enough, it will be all internet based.
I always like to be 100percent sure about who I advocate.
I think health is a most important topic for us human beings. I don't think one can ever be too obsessive when it comes to well being, not these days anyway with all the unhealthy temptations and our lack of discipline. I'm definitely not a perfect example of good health by no means, but I try to be. I'm not getting any younger thats for sure.
But I guess its up to every person themselves to determine whether promoting better health is worth it for them or not...
