foodquotient: Food Quotient and Nutrient Analysis for HSFFQ
Aids in analysing data from a food frequency questionnaire known as
the Harvard Service Food Frequency Questionnaire (HSFFQ).
Functions from this package use answers from the HSFFQ to generate
estimates of daily consumed micronutrients, calories, macronutrients on
an individual level.
The package also calculates food quotients on individual and group levels.
Foodquotient calculation is an often tedious step in the calculation of
total human energy expenditure (TEE) using the doubly labeled water method,
which is the gold standard for measuring TEE.
