Avocado glycemic index
Avocado has no measurable glycemic index: a 100 g serving (half an avocado) has only 1.8 g of available carbohydrate, so its glycemic load is about 0 and it barely raises blood sugar on its own.

What to know
Avocado is mostly fat and fiber with very little digestible carbohydrate, so its GI is not measurable and its glycemic load is close to zero.

Frequently asked questions
Does avocado 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. Avocado has 1.8 g per 100 g, so its direct effect on blood sugar is minimal and its glycemic load is about 0.
Does avocado 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 avocado?
A 100 g serving has about 8.5 g of total carbohydrate, including 6.7 g of fiber, leaving 1.8 g of available carbohydrate (the part that raises blood sugar). Per 100 g: 8.5 g of carbohydrate.
