HEI, Healthy Eating Index.
In parenthesis, the maximum number of points each element contributes to the HEI-2010. In boldface, if the difference between the mean of day 1 and the mean of day 2 is statistically different from zero (P < 0.1). se account for complex survey design. NHANES dietary intake day 2 weights (wtdr2d) were used to compute nationally representative estimates. Meal energy amounts exclude 0 values among those who do not eat the respective meal.
