Glucose risk
Avocados have a very low GI of approximately 15, with just 1.9 g of carbohydrate and 0.5 g of sugar per 100 g. Their high fat and fibre content means they have virtually no impact on blood glucose levels. Avocados are one of the safest foods for people monitoring blood sugar.

Whole avocados are an unprocessed fruit with a single ingredient. Even pre-ripened avocados remain NOVA 1. Prepared products like smashed avocado with added salt and lemon may be NOVA 2.
