In a new epidemiological study of ~23,000 people in Italy, pasta consumption as part of the Mediterranean diet was associated with lower BMI, lower prevalence of overweight/obesity, and better adherence to the Mediterranean diet. This runs counter to the common belief that pasta is "fattening."

The big issues in the study is that they looked at "self reported" 24 hour pasta consumption rates and correlated those with waist to hip ratios some of which were measured and others were again "self reported" by study participants.

While they looked at total caloric input the authors wholly ignored total caloric output of the people in the region being sampled. Caloric output being total daily activity levels, work performed etc. They also wholly ignored established nutritional and medical sciences involving carbohydrate intake and health outcomes and focused solely on correlations of hip to waist measurements and supposed pasta intake rates.

Those parts are a hell of a thing to simply ignore to make declarations that "findings counter beliefs". The findings are biased due to cherry picking of conditionals...

The fact that the study was funded by a pasta company further makes it seem like a marketing piece nothing more. I would take the outcomes in it with a really hefty load of salt.
