A new study charting 30 years of dietary change links increased consumption of ultra-processed foods to higher greenhouse emissions. Examples of ultra-processed foods include margarine, sausages, frozen meals, confectionery, soft drinks, sugary cereals, and snacks. These food and beverage categories contain multiple additives like flavors, sweeteners, and preservatives. High consumption of these food types has long been known to increase the likelihood of obesity, cardiovascular disease, diabetes, and some cancers. Now a new study has linked ultra-processed foods with increased environmental impact. The manufacture of these foods uses more water, land, and energy and requires additional packaging along the supply chain. The relationship between ultra-processed foods and the environment is a complex one, and more studies will be needed to prompt policy intervention.
