Uno degli studi epidemiologici più citati dai vegetariani è il ponderoso The China Study del dott. Colin Campbell www.thechinastudy.com/about.html. Provate a discutere con un vegetariano informato e presto o tardi cercherà di chiudere la discussione citando le conclusioni tratte dal dott. Campbell da tale studio, a torto ritenute definitive.
Qualcuno si è preso la briga di accedere ai dati originali e di ripassarli per le forche caudine della statistica applicata. Qui l'articolo: http://rawfoodsos.com/2010/07/07/the-china-study-fact-or-fallac/
Qui lo stesso lavoro fatto da un altro ingegnere che per mestiere analizza dati (data mining): http://www.amazon.com/Analyzing-the-China-Study-Dataset/forum/Fx1YJPR95OHW08P/TxY4S5EZD8Y2XE/1/ref=cm_cd_dp_ef_tft_tp?_encoding=UTF8&s=books&asin=1932100660&store=books
... This is not at all what Campbell's book implied the data said. As I said above, I am an engineer (with a PhD) with heart disease simply trying to find out what to eat. You do the math...
My day-job is analyzing hard drive failure statistics that result from usage and stress testing; I get paid to make the problems being studied go away. I have also recently had a triple bypass, ...
... For instance, the people who ate the most animal protein had 68.9% less heart disease (at 95% confidence) than those people who ate the least animal protein. The people who ate the most plant protein had 64.9% more heart disease (at 89% confidence) than those people who ate the least plant protein.
Here are some more interesting correlation from Kroeker's post, the first column numbers are correlation factors in % (the most negative number = the lowest mortality!) for mortality of all vascular disease age 35-69:
-48.0% - CHOLESTEROL INTAKE (mg/day/reference man)
-42.2% - SATURATED FATTY ACID INTAKE (g/day/ref...)
-70.7% - PERCENTAGE OF CALORIC INTAKE FROM FAT
-68.9% - PERCENTAGE ANIMAL PROTEIN INTAKE (for ref
-57.0% - PERCENTAGE OF CALORIC INTAKE FROM ANIMAL
-55.6% - ANIMAL FOOD INTAKE (g/day/reference man)
-54.8% - ANIMAL PROTEIN INTAKE (g/day/reference ma
-54.1% - FISH INTAKE (g/day/reference man, as-con)
-49.5% - TOTAL LIPID INTAKE (g/day/reference man)
-49.1% - PERCENTAGE ANIMAL FOOD INTAKE (for refere
-48.4% - MEAT INTAKE (red meat and poultry) (g/day
-46.6% - RED MEAT (pork, beef, mutton) INTAKE (g/d
