How to Lower Glycemic Effect of a Meal Even Further
As we have seen (What Determines Glycemic Effect), the presence of certain substances in the stomach and intestinal tract, during digestion (eg. fiber, acid or fat), can reduce the speed at which carbs are converted to glucose and thus reduce glycemic effect. By adding these items to our meal, we can lower it's glycemic impact on our system.
Add Soluble Fiber to Your Meal
Soluble fiber (eg. from oats, apples, citrus fruits) in the stomach or small intestine inhibits interaction between carbohydrate and the digestive enzymes, whose job is to break down the carb into glucose.
Add Food Acids to Your Meal
Acid (eg. from lemon juice or vinaigrette) in the stomach during digestion slows down stomach emptying and thus the conversion of carbs to glucose.
Add a Little Healthy Oil
Like acid, fat/oil retards stomach emptying and thus glucose metabolism. However, all oil is high in calories, while not all oil is healthy. So choose carefully, and add any oil sparingly. The best fats/oils are uncooked and unrefined. Choose ones like extra virgin olive oil, wheatgerm oil, canola, flaxseed (linseeds).
