'Food porn' is everywhere on social media, often tagged with terms like #yummy or #Instafood. But while showing off your eggs benedict or smashed avocado might rake in the likes, research suggests this habit could be contributing to the already vast food waste problem in the UK.

Around 50% of the world's food is wasted, but most people are unaware of just how much they throw away. In response, Sainsbury's is trialling the Winnow app, which acts as a smart meter to monitor food waste, hoping to change behaviour by drawing attention to the amount that goes in the bin.

In the UK – where 15 million tonnes of food is thrown away annually – supermarkets are mucking in to minimise waste. But how responsible do consumers feel? After all, 40% of them throw food away at least weekly. Canvas8 sat down with 20 Brits to find out how guilty they feel about wasting food.

Food waste is a huge problem, but a large part of the issue lies in the hands of restaurants, cafés and supermarkets, which sometimes means there’s little the average consumer can do to help. But Too Good to Go is changing this by serving up restaurant leftovers at discounted prices.
