Compendium of Dietary Files for the American Southwest™
Southwest Diet Food List
For each region/population group identified within the American Southwest, a relevant food list was constructed for the population.
- A food list was constructed for each region/population and only includes foods which are considered in the data sources available. Some of these foods are traditional/ethnic foods while others are those found in the western marketplace.
- While every possible food may not be included, a good faith effort was made to include relevant foods which are consumed in each region/population. The food lists were severely limited by the amount of information available to LifeLine scientists.
- Food preparation and storage methods were considered in cases where these types of data were available.
Consumption Parameters: Daily Intake Values
The daily intake value describes the amount of the food that is eaten on a given day when it is consumed. This value is entered into the software in terms of grams per day (which may include more than one eating event). It does not represent the grams per day consumed averaged across the whole population, but rather the amount eaten by a person on a day when the food is eaten. This value may be described by a point value, a collection of point values, or a distribution, thus preserving the intra-individual variation within the population. The daily intake is specific to the age group that is consuming the food and is also related to the season in which the food is consumed. Where there were insufficient data to describe age or seasonally related differences, values for the consumption parameters were held consistent across all age/season groups.
These principles hold true in general for DRG files, however, due to the way that the data were presented for the Southwest 1 and 2 dietary file, daily rates of intake were entered for each food. This limits the way that results can be interpreted when these files are used in an assessment. Please see the results section for a complete discussion of the effects of this method on the dietary files.
Consumption Parameters: Probability of Eating
The probability of eating is defined as the chance that a specific food is eaten by the individual within that age group on any given day within that season. The probability value differs across different people in the population and can be expressed as a point value, several point values, or as a distribution of values reflecting the variation across the population. This permits the inter-individual variation to be preserved. Where information is available, different values can be assigned to different age groups and seasons, again allowing for variation by use of distributions.
These principles hold true in general for files created using the DRG, however, due to the way that the data were presented for the Southwest 1 and 2 dietary files, daily rates of intake were entered for each food. This requires that the probability of eating be 1 for all age/season groups. This limits the way that results can be interpreted when these files are used in an assessment. Please see the results section for a complete discussion of the effects of this method on the dietary files.
The energy intake values reflect the sum of the caloric content on a day’s dietary record. For each region/population group a range of energy intakes was determined. This range of energy intakes is bound on the low side by the least number of calories associated with a daily dietary record and is bound on the high side by the greatest number of calories associated with a daily dietary record that is deemed reasonable by the assessor.
