Pasta is made from wheat
The implications of this research don’t necessarily apply to diabetics and prediabetics. They may need to limit pasta consumption. For the rest, enjoy in moderation. From the Nutrition and Diabetes journal:
“The traditional Mediterranean diet (MeD), a healthy eating behavior model, might be the basis for establishing nutrition guidelines as an outcome of health policies. Its health benefits in primary and secondary prevention of chronic diseases has long been studied since middle 50s and confirmed by meta-analysis. Major components of the MeD are foods with high content of complex carbohydrates and fiber such as legumes, rice and cereals. The latter represent the main source of carbohydrates in the diet and in Italy, they are consumed mainly in the form of pasta.”

Uh, might want to read further than the headline and conclusions – this is one messed up “study”…
Good point, Ash.
By no means do I necessarily endorse things I link to. I was surprised when I saw the headline. After all, wheat flour is mostly sugar molecules linked together, like all starches.
