FIGURE 1.
Percentages of children (age 2–18 y; n = 28,373) (A) and adults (age ≥ 19 y; n = 45,088) (B) with intake of live microbe–containing foods (Med, Hi, and MedHi) and percentages of subjects consuming a PS by NHANES study periods. Sex-combined data. All β and P values represent regression coefficients and significance for change over time. Hi and Med were categories assigned to food codes; MedHi represented aggregated consumers of foods from Med, Hi, or both Med and Hi. Hi, estimated to contain >107 CFU/g; Med, estimated to contain 104–107 CFU/g; MedHi, estimated to contain >104 CFU/g; PS, probiotic supplement.
