No evidence is available to determine the relationship between the frequency of eating and all-cause mortality. (Grade: Grade Not Assignable)

The question is: What is the relationship between the frequency of eating and all-cause mortality?

No evidence is available to determine the relationship between the frequency of eating and all-cause mortality

This important public health question was identified by the U.S. Departments of Agriculture (USDA) and Health and Human Services (HHS) to be examined by the 2020 Dietary Guidelines Advisory Committee.

The 2020 Dietary Guidelines Advisory Committee, Frequency of Eating Subcommittee conducted a systematic review to answer this question with support from the Nutrition Evidence Systematic Review (NESR) team.
Frequency of eating was defined as the number of daily eating occasions.

The population of interest was generally healthy children through older adults (ages 2 and older).

The 2020 Dietary Guidelines Advisory Committee, Frequency of Eating Subcommittee conducted a systematic review to answer this question with support from the Nutrition Evidence Systematic Review (NESR) team.
The goal of this systematic review was to examine the following question: What is the relationship between the frequency of eating and all-cause mortality?

No evidence is available to determine the relationship between the frequency of eating and all-cause mortality. (Grade: Grade Not Assignable)

A literature search was conducted using 3 databases (PubMed, Cochrane, and Embase) to identify articles that evaluated an intervention or exposure of the frequency of eating and the outcome of all-cause mortality. A manual search was also conducted to identify articles that may not have been included in the electronic databases searched. Articles were screened by two authors independently for inclusion based on pre-determined criteria.
Because no articles were identified in the literature search, this systematic review did not involve data extraction, risk of bias assessment, or evidence synthesis. However, a conclusion statement was developed, that acknowledged the absence of evidence to address this question. Since no evidence was available to answer this question, the strength of evidence could not be graded.

This systematic review was undertaken to examine the relationship between the frequency of eating and all-cause mortality.
All-cause mortality was defined as the total number of deaths from all causes during a specific time-period.
This review identified 0 studies published between January, 2000 and June, 2019 that met the inclusion criteria for this systematic review.
