Hemp heart seeds are often hailed for their protein and healthy fat offerings. While seeds, in general, are lower in carbohydrates, the carbs they do provide are healthy and hard-working. A serving of hemp heart (3 tablespoons), has just 2.6 grams of carbohydrates—half of those (1.2 grams) come from fiber.
Due to their fiber to carbohydrate ratio and their protein and fat offerings, hemp hearts have a low glycemic index like other nuts and seeds.
