Each bar contains 10g of plant protein from a combination of nuts and peas. They are high in fibre, use no artificial colours or preservatives, are gluten free and suitable for vegetarians. The new bar comes in two flavours of Almond, Peanut and Double Dark Chocolate and Cashew, Blueberry and Dark Chocolate.
Earlier this year Nestlé said it planned to accelerate the development of plant-based meat and dairy alternatives with lower carbon footprints through a partnership with two key players in the plant protein sector.
Nestlé said its own recent research has shown that most people buying protein bars are now looking for more natural protein sources with no additives.
The bars will be available from September 2020 in European countries including the UK, Germany, Netherlands, and the Czech Republic
Nestlé said that as with its existing YES! range, the bars were wrapped in recyclable paper from sustainable sources, certified by the Forest Stewardship Council (FSC) or the Programme for the Endorsement of Forest Certification.
Alexander von Maillot, global head of confectionery at Nestlé, said: "We know that today people are living healthy active lifestyles and are looking for the right fuel that is good for them and for the environment.
“YES! plant protein bars use the power of nature to deliver a great wholesome product on the go and are wrapped in paper packaging that is easy to recycle and avoids plastic waste."
Louise Barrett, head of the Nestlé Confectionery Product Technology Centre in York, said: "Pea protein is a key focus area for us because it has a high protein content and is one of the most environmentally friendly sources of plant protein. When developing these new YES! bars, we chose pea and nut protein to really stand out from many of the other bars on the market. At the same time, we made sure that taste was our top priority, and these bars taste really amazing."
In April, Nestlé moved to reassure staff after a worker at its chocolate factory in Halifax tested positive for COVID-19.
