Since the project was launched three years ago it has delivered 162 million additional portions of vegetables into the food system across all four nations.
According to the Food Foundation vegetable intake remains a ‘huge problem’ in Britain, with 80% of adults and children failing to eat enough.
Anna Taylor, executive director the Food Foundation, said: “It is great to see 100 major food businesses commit to increasing veg consumption to support better health for millions of people.
“Transparent and regular reporting against targets is vital if we are to turn the tide on our current dietary crisis and see future generations face a better and healthier future with everyone having access to an affordable and sustainable diet.”
Waitrose, Tesco and the University of Sterling are amongst the businesses that have signed up to the Peas Please project. Around 80% of UK retailers are now committed to help drive up vegetable consumption.
Joanne Lunn, health manager at Waitrose, added: "We're committed to helping our customers make healthy choices and are proud to have signed up to the Food Foundation's Veg Pledge.
“We have lots of activity in place to inspire our customers, including exciting veg-based recipes, tips and advice, as well as Cookery School classes and events."
