From food databases to dietary assessment: A beginning to an end approach for quality nutrition data

Abstract

Aim: This paper reviews the historical basis of modern assessment of nutrient composition—from food composition tables and the transition to nutrient databases. Method: A narrative review was formed beginning with the first, very crude printed food composition tables, to electronic food databases and continuing to how dietary assessment is currently impacted by state‐of‐the‐art techniques and what that means for food composition. Results: A plethora of studies, especially international studies, have utilised information from food composition via nutrient databases and software designed to extract food composition data into relevant files for dietary assessment. The United States Department of Agriculture's nutrient data bank is widely used, even internationally, and concerns about its appropriateness in other locales needs to be addressed. A number of countries have developed food composition databases unique to the foods of their population. International studies realised a number of problems related to inconsistencies between countries. Essentially, high‐quality food composition data requires up‐to‐date information on food supply, supplement use and potential food contaminants. Food composition tables form the basis for data published on nutrient intakes of individuals via food diaries, food recalls and surveys and, in addition, nutrient claims for some food products; thus, accuracy and reliability are paramount. New tools in dietary assessment, such as food photography, make nutrient assessment more widely available, requiring even more attention paid to the accuracy of food composition databases. Conclusions: The globalisation of food sources and the need for continuity regarding dietary data present challenges needing reconciliation. International concepts for food composition tables have evolved to address these problems.

Early Antibiotic Exposure Is Not Detrimental to Therapeutic Effect from Immunotherapy in Hepatocellular Carcinoma

“…Challenges in its management stem from the high proportion of diagnoses that happen incidentally at an advanced stage, when treatment with curative intent is not an available option, resulting in life-limiting prognosis [2]. Cytotoxic chemotherapy has no role in the management of HCC and although sequential use of molecularly targeted therapies improves survival in advanced disease, therapeutic resistance limits long-term survivorship [3].…”

Evaluating the Nutritional Properties of Food: A Scoping Review

“…Numerous FCDBs have sprung up since the 1980s, including Latinfoods, Asiafoods, Oceaniafoods, Norfoods, and Eurofoods. Eurofoods includes both Eastern and Western Europe [ 53 ]. American food nutrition data are provided by FoodData Central (FDC), the center of the US Department of Agriculture’s (USDA’s) food composition information website.…”

“…In addition, we noted that food composition tables are rarely consistent across countries. Many foods are defined or presented in different ways, making comparison of nutrient compositions difficult [ 53 ].…”

Health Apps in Primary Care

“…These apps rarely include micronutrient or protein content and thus will not provide an overall assessment of the diet. Furthermore, data regarding nutrient content of different foods may vary depending on where they are grown/produced [1][2][3], and information on this will not necessarily be made available. Another challenge is portion size.…”
