Quaker Oatmeal, one of the oldest and most reliable food boxes, has ALWAYS (I mean all my lifetime) had a table of servings beginning with 1 serving equals 1/2 cup oatmeal, 1 cup water, and 1 dash salt, optional; the calorie count in the federally mandated information-box is 1/2 cup, 150 calories. My newest box -- same old cylinder with the Quaker's picture on the logo -- includes the same table of measured amounts, but with a new column in red:
HEART HEALTHY SERVING SIZE:Never mind the noble pretense -- Quaker Oats is supersizing!
3/4 cup oatmeal
1-1/2 cups water
dash of salt
