In-home and shared meals have been hypothesized to have positive effects. This narrative review examines research on the influence of in-home eating on diet quality, health outcomes, and family relationships.
Evidence suggests that there have been shifts in dietary practices over the past few decades, with less time devoted to food shopping, cooking, and in-home eating despite the potential benefits of in-home food preparation and eating

[1]
. Paralleling this decrease in time spent preparing food in the home and changes in diet is the worldwide increase in diet-related health concerns such as obesity and diabetes
.
In light of these trends, health experts are seeking effective strategies to combat the obesity epidemic, including the possible role of in-home and family-shared meals. Some research suggests a potential protective effect of home meals on child health, psychosocial outcomes, and family relationships
[4]
. For example, dining together in the home has been proposed to foster self-esteem, promote academic achievement, and protect against substance abuse in adolescents
[5][6][7]. To date, however, there is no available review of current evidence for benefits of in-home meals on diet quality and meal patterns, health outcomes, psychosocial factors, and family relationships.

The purpose of this narrative literature review is to examine the evidence regarding the effects of in-home eating and shared meals. Specifically, the review examines the scientific literature on: (1) factors associated with in-home eating (e.g., lifestyle habits, family demographics); (2) the impact of in-home eating on the nutritional quality of meals; (3) the relationship between in-home eating and child and adolescent health outcomes; and (4) the influence of in-home eating on family relationships.

Primary data-based articles and review articles were included in this literature review, which was initially conducted between January and April 2016. Search terms used included: “Home Meals”, “Meals Served in the Home”, “Family Mealtimes”, “Diet Quality”, “Dietary Patterns”, “Health Outcomes”, “Health Behaviors”, “Family Relationships”, and “Psychosocial Outcomes”. A combination search approach was used that included a search of the PubMed database, backward searches of previous published reviews on the topic, and studies the authors were familiar with based on their combined 25 years of research in the area. In the initial literature search, 112 publications were identified and of these, 48 original studies and 11 additional review publications were considered suitable to include in this review. Publications were excluded if they did not report on original data or a systematic review on this topic, or if they were found to be tangential to the main review question. An updated search in May 2018 yielded six additional relevant primary research articles. Analysis of the literature was completed in 2018–2020 (See Figure 1).

Studies were organized into categories based on the review questions. Most of the studies were conducted in the U.S., but we have noted non-U.S. study locations in the Results tables where applicable. A preliminary scan revealed the literature is comprised of mostly cross-sectional studies, a variety of methods and measures, and few randomized controlled trials. This limited the ability to apply formal statistical comparisons to the body of literature, so a narrative review approach was chosen, whereby the review team members would each examine studies within outcome categories, summarize their observations, and discuss the findings with the team until consensus was reached. Narrative reviews are preferred when the body of research cannot be summarized quantitatively due to the heterogeneity of research methods and statistical analyses

We examined the available studies to summarize whether in-home eating and meal sharing are associated with energy intake, fruit and vegetable intake, nutrient intake, dietary patterns, and overall diet quality in children and adolescents. The majority of the studies to date have been cross-sectional (16), and a smaller number are longitudinal (4). In addition, four systematic reviews have been published. Overall findings suggest a positive association between the frequency of family meals and favorable dietary outcomes (Table 1).Table 1. Summary of Diet Quality and Meal Patterns.

Project EAT, a longitudinal study conducted in the U.S. Midwest, has contributed substantially to the literature regarding the influences of family meals on the dietary outcomes of adolescents
We examined the available studies to summarize whether in-home eating and meal sharing are associated with energy intake, fruit and vegetable intake, nutrient intake, dietary patterns, and overall diet quality in children and adolescents. The majority of the studies to date have been cross-sectional (16), and a smaller number are longitudinal (4). In addition, four systematic reviews have been published. Overall findings suggest a positive association between the frequency of family meals and favorable dietary outcomes (Table 1).
Project EAT, a longitudinal study conducted in the U.S. Midwest, has contributed substantially to the literature regarding the influences of family meals on the dietary outcomes of adolescents
. In our review, five empirical research reports drew from the Project EAT dataset and all four systematic reviews included Project EAT findings. It is noteworthy that most studies used intakes of specific food groups, typically fruit and vegetable consumption, as a proxy for diet quality; and only one used a validated measure of overall diet quality (the Diet Quality Index–International)
[13]
. Additionally, while most of the research was conducted in the U.S., a portion of the literature is based on studies in Europe and other nations outside of the U.S.

The conclusions mostly apply to the U.S. cultural context and food environment.Family meal frequency is positively associated with fruit and vegetable and dairy intakes and breakfast eating; and negatively associated with fried foods, unhealthy snacks and cakes, and sugar-sweetened beverage intake

Despite what is increasingly becoming “common wisdom,” the evidence that in-home, shared meals, per se, have direct positive effects on diet quality, health outcomes, psychosocial outcomes, and family relationships is greatly limited by research designs and measurement of the hypothesized independent variable. Measures should include how food is prepared and served in the home, not merely whether children and parents eat together, as well as the quality of meals. There is a need for more longitudinal studies that track changes in mealtime frequency and family dynamics over time to predict changes in diet quality, health outcomes, psychosocial outcomes, and family relationships; while incorporating appropriate controls for other factors that may predict key outcomes as well as meal-sharing. More adequately powered intervention studies and randomized trials are needed. Intervention studies that avoid “ceiling effects” by including mainly those who already share meals frequently are also needed. Further, there is a need to pay more attention to family diversity in terms of race/ethnicity, socioeconomic status, household composition, and parenting roles.
The emerging results suggest that shared meals and in-home eating may have protective effects against child and adolescent overweight/obesity. However, much more research, with stronger designs and more rigorous measurement of predictors, is warranted.
