Study shows relationship with food waste, diet quality, environmental sustainability
Higher quality diets were associated with greater amounts of food waste and greater amounts of wasted irrigation water and pesticides, but less cropland waste.
Improving diet quality while simultaneously reducing environmental impact is a critical focus for many of today’s consumers. However, metrics linking diet quality and sustainability typically don’t include food waste.
To address this research gap, a research study from PLOS ONE, San Francisco, examined the relationship between food waste, diet quality, nutrient waste and multiple measures of sustainability, such as use of cropland, irrigation water, pesticides and fertilizers.
