These muffins are not too sweet and are filled with whole grains. The museli, sucanat sugar, and flax seeds help to lower the glycemic index. As with almost all baked goods, these muffins do not have a low glycemic load, so enjoy them in moderation. For the museli, I like to use Bob's Red Mill. You can substitute the muesli with granola, but it will increase the fat and calories. Enjoy!
