The verdict

Lucky Charms carries 10g of added sugar per serving — about 40% of a child's daily 25g AHA allowance — plus the marshmallows that make it a magnet for kids. The ingredient list is long: sugar and corn syrup both appear, along with the synthetic dyes Red 40, Yellow 5, Yellow 6, and Blue 1 in the marshmallow colors, and the preservative BHT. It's Tier E on sugar alone; the dye load is a second reason pediatric behavioral specialists flag it.
