Fast food restaurants are significantly more prevalent in low-income and ethnic minority neighborhoods compared to white or higher-income neighborhoods.
If you live in a food desert or a neighborhood with high fast food density, you are facing a structural disadvantage. Advocate for policy changes like zoning restrictions or incentives for healthy grocers, as individual effort alone cannot easily overcome the sheer density of unhealthy options.

76% indicated fast food restaurants were more prevalent in low-income areas compared with middle- to higher-income areas. Ten of 12 studies found fast food restaurants were more prevalent in areas with higher concentrations of ethnic minority groups in comparison with Caucasians.
Why this rating
