zation, and they tend to lose lean body mass over time (Gaffney-Stomberg et al., 2009).

Intakes of selected nutrients that have an Adequate Intake (AI) rather than an EAR are shown in Table 5-3, by age group and gender, along with the respective AI. The mean and median NHANES (2003–2004) intakes for calcium, potassium, and fiber are lower than the AI for most of these adult age-gender groups, suggesting that the majority of individuals do not meet this target recommendation. Women have lower intakes than do men, with mean and median potassium intakes less than half the α-linoleic and α-linolenic acid intakes are close to the AI on average.
