Vorrei sapere se la dieta vegetariana potrebbe apportare miglioramenti al livello glicemico. Frequento una palestra due volte a settimana, persi 6-8 kg.Risponde il prof. Leonardo Pinelli, diabetologo:
Sicuramente sì. L’alimentazione vegetariana ben organizzata (mi raccomando) è sicura in tutte le fasi della vita dell’uomo. È inoltre assolutamente indicata in alcune patologie, fra cui il diabete.
Questo concetto è espresso chiaramente in un articolo pubblicato da poco dal British Journal of Nutrition di cui sotto riporto la parte dedicata a vegetarismo e diabete.“Teaching children with diabetes about adequate dietary choices”

“.......Vegetarian diet
A small fraction of individuals living in industrialized countries have a vegetarian diet, although vegetarianism is becoming more popular. Several studies have shown that a plant-based diet high in fibre-rich foods, such as vegetables, fruits, cereals, whole grains and legumes, is inversely related to BMI, overweight and obesity, blood pressure, blood lipids, cancer, heart disease and all-cause mortality(52 57). Recent data suggest that diabetes care has benefited from a vegetarian diet(58,59).
In fact, a low-fat plant-based diet influences nutrient intake and body composition in several ways that may, in turn, affect insulin sensitivity. First, dietary energy density and energy intake are reduced in a low-fat, high-fibre diet. The weight-reducing effect of the vegan diet is probably responsible for a substantial proportion of its effect on the reduction of the HbA1C(58 60). Second, reductions in total fat intake and in the proportion of dietary saturated to unsaturated fat as well as the increased intake of low-glycaemic-index and high-fibre foods increase insulin sensitivity(59,60).
Few data are available in children with type 1 diabetes having a vegetarian diet. Kontessis et al. demonstrated that a vegetarian diet is able to improve microalbuminuria in normotensive, normoproteinuric children with type 1 diabetes(61).
Moreover, the American Dietetic Association and the Dietitians of Canada suggest that well-balanced vegetarian diets are healthy and adequate from a nutritional standpoint and have health benefits for the prevention and treatment of certain pathologies(62). Type 1 diabetes is potentially one of these.
