E' un argomento collegato alla salute dello scheletro, ma lo metto in evidenzia qui. E' stato appena pubblicato un primo studio, molto semplice direi, che ha seguito 30 vegetariani e 30 non-vegetariani analizzandone la dieta, e ha trovato che i vegetariani hanno una dieta decisamente più alcalina dei vegetariani, più "acidi". Mi sembra che anche in termini numerici le differenze siano piuttosto forti.

Abstract A first objective of the present study was to estimate the
acid-base balance of the food intake in vegetarians and
non-vegetarians. A second objective was to evaluate if additional
input of specific food items on the existing potential renal acid load
(PRAL) list was necessary for the comparison of the two dietary
patterns. Thirty vegetarians between the age of 18 and 30 years were
matched for sex, age and BMI with 30 non-vegetarians. Based on the
3-days food diaries the acid-base status of the food intake was
estimated using the PRAL method. Mean PRAL values as estimated with the
standard table yielded an alkaline load of -5,4â€‰Â±â€‰14,4 mEq/d in the
vegetarians compared to an acid load of 10,3â€‰Â±â€‰14,4 mEq/d in the
non-vegetarians (pâ€‰<â€‰0,001). Mean PRAL values as estimated with the
extended table yielded an alkaline load of -10,9â€‰Â±â€‰19,7 mEq/d in the
vegetarians compared to an acid load of 13,8â€‰Â±â€‰17,1 mEq/d for the
non-vegetarians (pâ€‰<â€‰0,001). The findings of this study indicate that
vegetarian food intake produces more alkaline outcomes compared to
non-vegetarian diets. The use of the standard PRAL table was
sufficient for discrimination between the two diets.
