(i) To determine the current state of online grocery shopping, including individuals’ motivations for shopping for groceries online and types of foods purchased; and (ii) to identify the potential promise and pitfalls that online grocery shopping may offer in relation to food and beverage purchases.
PubMed, ABI/INFORM and Google Scholar were searched to identify published research.
To be included, studies must have been published between 2007 and 2017 in English, based in the USA or Europe (including the UK), and focused on: (i) motivations for online grocery shopping; (ii) the cognitive/psychosocial domain; and (iii) the community or neighbourhood food environment domain.
Our search yielded twenty-four relevant papers.
Findings indicate that online grocery shopping can be a double-edged sword. While it has the potential to increase healthy choices via reduced unhealthy impulse purchases, nutrition labelling strategies, and as a method to overcome food access limitations among individuals with limited access to a brick-and-mortar store, it also has the potential to increase unhealthy choices due to reasons such as consumers’ hesitance to purchase fresh produce online.
Additional research is needed to determine the most effective ways to positively engage customers to use online grocery shopping to make healthier choices.
The aim of the study was to determine the association between dietary outcomes and the neighbourhood food environment (street network distance from home to stores) and consumer food environment (Nutrition Environment Measurement Survey-Stores (NEMS-S) audit).
The neighbourhood food environment was captured by creating 0·5-mile and 1-mile network distance (street distance) around each participant's home and the nearest food venue (convenience store, grocery store, supermarket, farmers' market and produce stand). The consumer food environment was captured by conducting NEMS-S in all grocery stores/supermarkets within 0·5 and 1 mile of participants’ homes.
Fayette County, KY, USA.
Supplemental Nutrition Assessment Program (SNAP) participants, n 147.
SNAP participants who lived within 0·5 mile of at least one farmers’ market/produce stand had higher odds of consuming one serving or more of vegetables (OR = 6·92; 95 % CI 4·09, 11·69), five servings or more of grains (OR = 1·76; 95 % CI 1·01, 3·05) and one serving or more of milk (OR = 3·79; 95 % CI 2·14, 6·71) on a daily basis. SNAP participants who lived within 0·5 mile of stores receiving a high score on the NEMS-S audit reported higher odds of consuming at least one serving of vegetables daily (OR = 3·07; 95 % CI 1·78, 5·31).
Taken together, both the neighbourhood food environment and the consumer food environment are associated with a healthy dietary intake among SNAP participants.
The present study aimed to highlight the similarities and differences between perceived and objective measures of the food store environment among low-income women and the association with diet and weight.
Cross-sectional analysis of food store environment. Store level was characterized by: (i) the availability of healthy foods in stores where participants shop, using food store audits (objective); and (ii) summary scores of self-reported perception of availability of healthy foods in stores (perceived). Neighbourhood level was characterized by: (i) the number and type of food stores within the census tract (objective); and (2) summary scores of self-reported perception of availability of healthy foods (perceived).
Six counties in North Carolina.
One hundred and eighty-six low-income women.
Individuals who lived in census tracts with a convenience store and a supercentre had higher odds of perceiving their neighbourhood high in availability of healthy foods (OR = 6·87 (95 % CI 2·61, 18·01)) than individuals with no store. Overall, as the number of healthy foods available in the store decreased, the probability of perceiving that store high in availability of healthy foods increased. Individuals with a supercentre in their census tract weighed more (2·40 (95 % CI 0·66, 4·15) kg/m2) than individuals without one. At the same time, those who lived in a census tract with a supercentre and a convenience store consumed fewer servings of fruits and vegetables (−1·22 (95 % CI −2·40, −0·04)).
The study contributes to a growing body of research aiming to understand how the food store environment is associated with weight and diet.
