ACI, absolute concentration index; CI, confidence interval.

¹⁾The criterion for fat consumption is that the contribution of the dietary intake to the total energy is 15–30% for subjects 19 years old and 15–20% for subjects ≥ 20 years; ²⁾The criteria for healthy eating practices is for individuals to meet ≥ 2 out of 4 healthy eating practices: (1) fruit and vegetable intake; (2) use of nutrition labeling; (3) sodium intake; and (4) fat consumption.
