Most MEC participants (87 percent) have 2 days of complete and reliable intakes. The first day (Day 1) is collected in the Mobile Examination Center (MEC) and the second day (Day 2) is collected by telephone 3 to 10 days later. One of the most important changes is the release of two days of intake data for each participant. The table below summarizes these changes.

The dietary interview component, called What We Eat in America (WWEIA), is conducted as a partnership between the U.S. Selected population subgroups are asked questions on frequency of fish and shellfish consumed during the past 30 days. Following the dietary recall, participants are asked questions on water consumption during the previous 24 hours, salt use, whether the person’s intake on the previous day was usual or unusual, and whether the respondent is on any kind of diet.
The dietary intake data are used to estimate the types and amounts of foods and beverages consumed during the 24-hour period prior to the interview (midnight to midnight), and to estimate intakes of energy, nutrients, and other food components from those foods and beverages. The objective of the dietary interview component is to obtain detailed dietary intake information from NHANES participants.
