Which foods on this list should I be most careful about?
Of the 100 foods listed, 100 are rated Limit (GL ≥20 per 100g). These have the highest blood sugar impact and should be eaten sparingly — small portions, on occasion, always paired with protein and fiber. The remaining 0 — 0 diabetes-friendly and 0 moderate — are lower-GL choices for regular meals.
What portion size should I aim for?
Pairing is as important as portioning. Adding protein and fiber to any meal with these foods slows gastric emptying and creates a smoother glucose curve. The difference between eating a food alone versus as part of a balanced meal can be 20-40% in peak blood glucose.
How often should I check my blood sugar after eating these?
Individual blood sugar responses vary. The GL numbers are population averages — your personal response may be different. If you wear a CGM or check your blood sugar, test your response to specific foods from this list. Note which ones produce the smoothest curve for you, and build your regular rotation around those.
Can cooking method change the glycemic impact?
Cooking method can matter, particularly for grains and starchy vegetables. Cooling and reheating increases resistant starch (lowers effective GI). Al dente cooking leaves more intact starch structure. Overcooking or pureeing breaks down fiber and increases the glycemic response.
