Practical Guidance
💡 Cook Lightly or Eat Raw
Overcooking breaks down vegetable fiber and can increase glycemic impact. Light steaming preserves structure and nutrients.
💡 Check Your Own Response
Individual blood sugar responses vary. Use a glucose meter to understand how this food affects you personally.
💡 Glycemic Load Over Glycemic Index
GL accounts for both the speed AND amount of carbohydrate, making it more practical for real-world eating than GI alone.
💡 Pair Carbs With Protein
Adding protein to a carbohydrate-containing meal slows digestion and helps prevent blood sugar spikes.
