Preferably something that has little to no preparation required.
If you mean stuff like brown sugar cinnamon Quaker brand, that stuff has more sugar than Count Chocula or Fruit Loops.
I found the nutritional label, which reports 10 grams of sugar per packet. That, to me, is reasonable. I did not look up the nutritional information of the cereal, but remember that sugar content isn’t the whole story. The cereal is more or less deficient in nutrients whereas oatmeal isn’t. Oatmeal is a complex carbohydrate.
As another example, if you had a banana and whole oats, no sugar, that meal would be obviously very healthy but nominally have 15 g of sugar.
That’s odd, I was looking at their ‘reduced sugar’ product https://www.quakeroats.com/products/hot-cereals/lower-sugar/maple-and-brown-sugar where they say this,
‘50% less sugar than regular Quaker® Instant Oatmeal Maple & Brown Sugar flavor* *Sugar content (on 55g basis): Lower Sugar Maple & Brown Sugar: 7g. Regular Maple & Brown Sugar flavor contains 16g sugar.’
Certainly I agree oats aren’t a nutritional vacuum like sugar cereal. But if that 16g is correct that is half a Snickers bar.
