Get FAO Food Composition Data
get_fao_composition.RdThis function retrieves and processes food composition data from the FAO database. It specifically focuses on marine food items such as octopus, squids, cockles, shrimps, crabs, and lobsters. The data is filtered, categorized for various nutrients including protein, calcium, iron, zinc, selenium, vitamin A, and omega-3 fatty acids.
Value
A tibble with values for various nutrients for each category of marine
food items. The columns include Protein_mu, Calcium_mu, Iron_mu, Zinc_mu,
Selenium_mu, Vitamin_A_mu, and Omega_3_mu.
Details
The function first reads a CSV file from a given URL using the read_csv function from
the readr package. It then defines specific codes for various marine food groups:
octopus, squids, cockles, shrimps, crabs, and lobsters. The FAO composition data is then
filtered for these food items in their raw state. A new interagency_code is created
for categorization purposes. The nutrients considered are protein, calcium,
iron, zinc, selenium, vitamin A, and omega-3 fatty acids.
