The China Study

     Dr. T. Colin Campbell, Professor of Nutritional Biochemistry at Cornell University lead a study of 65 counties across 24 provinces in rural China.  It involved 6500 adults aged 35-64.  Dietary questionnaires, blood and urine samples were analyzed yielding over 347 data points for interpretation.
     Some key findings:
Fat intake:rural China 14% of total caloric intake vs US >35%
Protein intake: rural China 10% of calories from animal protein, US 70%
Total caloric intake of rural Chinese diet was 20-30% more that in US
     The diet consumed in rural China is plant based nutrition compared with the typical American diet based upon animal protein.
     The study analysis showed a tremendous difference in the incidence of "Diseases of Affluence", specifically cancer, heart disease and diabetes.  These diseases exist in very low rates in rural China compared to the US.  What's more, rural Chinese who emigrated to the US, adopting the local diet then developed these diseases at the same rate as native born Americans.  One finding I found to be particularly amazing involved a 3 county area in China with a population of over 400,000 in which, during the 3 years of the study, not a single person died from a heart attack.  In a comparable sized US region the rate of death from heart attacks is about 80 per year, so 240 over a 3 year period compared to zero.  I find that astounding.
     The effects of these dietary differences were also noted to impact other disease states i.e. kidney stones, osteoporosis, and autoimmune diseases.  The implications are broad.  Adopting a plant based diet can significantly impact the incidence and prevalence of the leading causes of death and disability in the U.S.  It will, however, take a tremendous change in our dietary habits.  
     Reading the China Study, as well as Dr. Esselstyn's Prevent and Reverse Heart Disease, has totally changed my perspective on diet and health.  I am now 2 months into my adoption of these dietary changes and feel great.  Join me, it's not as daunting a task as it first appears.   In fact it is quite simple.  Read the China Study, it is eye opening.

Cholesterol - It's not just bad for your heart

     It is widely publicized that high cholesterol levels are linked to coronary artery disease.  But.... did you know that the single biological factor associated with 'diseases of affluence' (diabetes, coronary artery disease and cancers of the brain, breast, colon, liver, stomach and leukemia) is..... you guessed it......Cholesterol.
     In the China Study,  Dr. T. Colin Campbell found that in rural China, where a plant based diet is followed the incidence of these diseases of affluence was extremely low.  In this region the average total cholesterol was 127! (The average in the US is ~200)
    More on this comprehensive study to come.
