About this food

How should I track Malt-O-Meal, Marshmallow Mateys?

Malt-O-Meal, Marshmallow Mateys is high in iron. The key to tracking Malt-O-Meal, Marshmallow Mateys is knowing whether you are logging dry or cooked weight. Grains absorb 2–3 times their weight in water during cooking, so 80 g of dry rice becomes about 200 g cooked. Mixing up dry and cooked values can throw your calorie count off by 200–300%. A meta-analysis (Reynolds et al., Lancet 2019) linked higher whole grain intake to reduced mortality — but only accurate tracking captures the real intake. Weigh on a kitchen scale before cooking and use the matching nutrition values.
