Idiotiskt att de aldrig ger källor till studierna; de måste man tydligen hitta själv.
Nåväl, detta är studien:
Cuenca-García, M., Ruiz, J., Ortega, F. and Castillo, M. 2013. Association between chocolate consumption and fatness in European adolescents. Nutrition.
Citat:
Higher chocolate consumption was associated with lower levels of total and central fatness, as estimated by BMI, body fat estimated from skinfolds and BIA, and waist circumference, regardless of potential confounders (P ≤ 0.01).
