Glycemic understanding

FoodApprox. GINotes
Red lentil pasta~22–35*Very high protein/fiber. Exact GI varies considerably by formulation; generally among the better pasta choices.
Chickpea / gram-flour roti~28Very low GI; higher protein and fiber than wheat roti.
Regular white durum pasta, al dente~27–45Surprisingly good. Pasta’s compact starch/protein structure slows digestion. A recent GI database entry measured boiled white pasta at 27. (Glycemic Index)
Black-bean pasta~30–40*High protein/fiber and tends to produce a substantially smaller glucose response than refined bread.
Chickpea pasta, cooled + reheated~33Excellent option. Cooling increases resistant starch; one controlled study found GI 33. (PubMed Central (PMC))
Chickpea pasta, freshly cooked~39Controlled testing found GI 39. Still firmly low-GI. (PubMed Central (PMC))
Barley roti~43Low GI; barley’s soluble fiber helps slow carbohydrate absorption.
Multigrain / dense grain bread~43–55Can be quite good when made with intact/coarse grains; finely milled “multigrain” may be much higher. (Glycemic Index)
Whole-wheat roti / chapati~45–60Usually a good conventional bread choice, especially thin roti made from whole atta.
Corn tortilla~50–52Relatively modest GI and usually a small carb portion.
Quinoa pasta~50-ish*Harder to assign a reliable universal GI. Pure quinoa is around the low-to-medium GI range, but many “quinoa pastas” contain substantial rice/corn flour, which can raise GI considerably.
Egg lasagna / durum pasta~53GI database value for boiled egg lasagna: 53. (Glycemic Index)
Dense 100% whole-grain bread~50–55Better when grain particles remain relatively intact.
Traditional pumpernickel~50–56Dense traditional rye versions are preferable to fluffy commercial “pumpernickel.”
Wholemeal / brown pita~56Better than white pita if genuinely wholemeal rather than simply colored brown.
Whole-wheat pasta~50–59More fiber than normal pasta, although GI is not necessarily dramatically lower than well-cooked regular durum pasta. GI database example: 59. (Glycemic Index)
Whole-wheat sliced bread~65–70“Whole wheat” doesn’t guarantee low GI; finely milled flour can digest rapidly.
White pita~65–68Medium-high GI; one pita may also contain ~30–35 g carbohydrate.
Corn pasta / some gluten-free pasta~68Often worse than wheat pasta. One tested gluten-free corn pasta had GI 68. (Glycemic Index)
Bagel~70High GI and usually a very large carbohydrate dose.
Naan~70–72Refined flour + large serving means substantial glycemic load.
White sandwich bread~73–75Rapidly digested refined flour.
Rice + corn gluten-free pasta~76Important surprise: gluten-free does not mean glucose-friendly. Tested rice/maize pasta had GI 76. (Glycemic Index)
French bread / baguette~70–80+Typically among the fastest-digested bread choices.
