En este análisis estadístico, de una gran cantidad de investigaciones a nivel internacional, se confirma algo que hace muchos años se comenzó a evidenciar: la evidente disminución, en vegetarianos, con respeto a omnívoros (quienes comen carnes) de la muerte por enfermedades cardiovasculares, junto con la disminución evidente de la incidencia de otra terrible enfermedad, el cáncer.
Con este trabajo se demuestra que la gran mayoría de las investigaciones, durante muchos años, en conjunto, han comprobado que estas dos enfermedades, las cuales están entre las principales causas de muerte en ciudades en el mundo (en Argentina las enfermedades cardiovasculares y ciertos cánceres, son las prinicipales causas de muerte por enfermedades) pueden ser disminuidas, en cuanto a incidencia, y como consecuencia a ello, su resultado mortal, al adoptar una dieta vegetariana.

Abstract
Background:
Prospective cohort studies have examined mortality and overall cancer incidence among vegetarians, but the results have been inconclusive.
Aims:
The objective of the present meta-analysis was to investigate cardiovascular disease mortality and cancer incidence among vegetarians and nonvegetarians.
Methods:
Medline, EMBASE and Web Of Science databases were searched for cohort studies published from inception to September 2011. Studies were included if they contained the relative risk (RR) and corresponding 95% CI. Participants were from the UK, Germany, California, USA, the Netherlands and Japan.
Results:
Seven studies with a total of 124,706 participants were included in this analysis. All-cause mortality in vegetarians was 9% lower than in nonvegetarians (RR = 0.91; 95% CI, 0.66-1.16). The mortality from ischemic heart disease was significantly lower in vegetarians than in nonvegetarians (RR = 0.71; 95% CI, 0.56-0.87). We observed a 16% lower mortality from circulatory diseases (RR = 0.84; 95% CI, 0.54-1.14) and a 12% lower mortality from cerebrovascular disease (RR = 0.88; 95% CI, 0.70-1.06) in vegetarians compared with nonvegetarians. Vegetarians had a significantly lower cancer incidence than nonvegetarians (RR = 0.82; 95% CI, 0.67-0.97).
Conclusions:
Our results suggest that vegetarians have a significantly lower ischemic heart disease mortality (29%) and overall cancer incidence (18%) than nonvegetarians.
