Frequently asked questions
Does bell pepper have a glycemic index?
Not a measurable one. GI can only be tested in foods with enough carbohydrate: the test needs a 25 or 50 g carbohydrate portion. Bell pepper has 3.9 g per 100 g, so its direct effect on blood sugar is minimal and its glycemic load is about 0.
Does bell pepper raise blood sugar?
Barely, on its own. What matters more is what you eat it with: bread, rice, potatoes, sauces or sugary drinks. Pairing carbohydrate foods with protein, fat or fiber tends to soften the rise.
How many carbs are in bell pepper?
A 80 g serving has about 4.8 g of total carbohydrate, including 1.7 g of fiber, leaving 3.1 g of available carbohydrate (the part that raises blood sugar). Per 100 g: 6 g of carbohydrate.
