The researchers, who hope that their research might permit shoppers to buy extra sustainably with out sacrificing something to their well being, additionally in contrast the outcomes with the dietary qualities of those meals.
They discovered that juice concentrates, sodas or different fruit juices are among the many merchandise bought with the bottom environmental affect — as a result of they’re largely composed of water — however their dietary high quality is poor.

However “smaller” transitions also can assist. For instance, beef lasagna, with a excessive environmental affect, may very well be changed by rooster or pork lasagna, or vegetarian.
Sooner or later, higher figuring out the proportions and origin of various components would assist to find out extra exactly their affect on the setting, the researchers stated.
