Salmon glycemic index
Salmon has no measurable glycemic index: a 120 g serving (1 portion) has only 0 g of available carbohydrate, so its glycemic load is about 0 and it barely raises blood sugar on its own.

Frequently asked questions
Does salmon 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. Salmon has 0 g per 100 g, so its direct effect on blood sugar is minimal and its glycemic load is about 0.
Does salmon 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 salmon?
A 120 g serving has about 0 g of total carbohydrate, including 0 g of fiber, leaving 0 g of available carbohydrate (the part that raises blood sugar). Per 100 g: 0 g of carbohydrate.
