referred to as “good carbs”.
Best Food Sources of Carbohydrates
A. Raw or lightly steamed vegetables
B. Most whole, raw, fresh fruit
C. Beans, legumes, nuts and seeds
D. High fiber 100% whole grains
Glycemic Index
V. Glycemic Index: The higher a food
is on the glycemic index scale of 0 to
100, the higher it raises blood sugar.
The lower the glycemic index number,
the lower the impact on blood sugar.
Basically, pure proteins and fats don't
raise blood sugar levels.
