High-glycemic diets are associated with type 2 diabetes, cardiovascular disease, diabetes-related cancers, and all-cause mortality. Foods with a high glycemic index cause an increase in blood sugar concentration called a "glycemic spike" It is better to choose whole grains, eat them cold and avoid foods that contain added sugar.
cooked pasta has a higher GI than al dente pasta; If it is dressed with vegetables and fish instead of oil and Parmesan cheese, the glycemic load of that meal is reduced even further.
