Adherence

Living in neighborhoods with ready access to healthy foods (e.g., supermarkets) is associated with more healthful diets and lower prevalence of obesity, whereas high density of fast-food restaurants has weak or mixed evidence for causing obesity.

Prioritize living in or supporting communities that have accessible supermarkets or fresh food options. Be aware that simply having fast food nearby does not necessarily dictate your weight, but having access to healthy options supports better dietary choices. Look for communities that offer both access and safety.

ModerateQualifiesMEDIUM confidence
Residents of communities with ready access to healthy foods also tend to have more healthful diets... evidence regarding the relationship between individuals’ weight status and the density of restaurants in their neighborhood is weak and has not been supported in large studies of children and adults in both rural and urban areas.

Why this rating

Most studies are cross-sectional; prospective and quasi-experimental evidence is emerging but not yet conclusive for all aspects (like fast-food density).
