What to know about Sustainable Consumption

Researchers from Simon Fraser University analyzed grocery data from Canada and Finland to examine how price and variety affect the purchase of plant-based versus animal-based proteins. The study suggests that while price is a factor, a lack of affordable variety in plant-based options limits consumer flexibility compared to meat products.

Study explains why shoppers avoid plant-based proteins Lisa Lock Scientific Editor Andrew Zinin Lead Editor Incorporating more plant-based proteins could help people save on their grocery bill, but new research has found that it's not so simple when it comes…

Why it matters

Simon Fraser University researchers peeked into more than 87,000 grocery carts in Canada and Finland to study how much price influenced the type of protein people bought: animal-based or plant-based.

Common ground

Researchers discovered that while the price had to be right, having a variety of options also played a role.
