According to End+Stems’ Alison Mountford, it’s hard to measure household food waste at the scale of the individual home. She reports that 40% of all food produced is wasted and that 67% of the we waste at home is edible. In other words, the average family of 4 is throwing out upwards of $2100 worth of food annually. However, few people can say how much they themselves are wasting, why they wasted it, or which foods are most commonly going to waste.
Because it’s easy to overlook what goes in the trash, she recommends a food audit similar to a food journal. For 1 week, you and your family/housemates keep track of all edible items that throw out. Afterwards, you have a starting point to make simple changes to your household norms and routine.
Ends+Stems is laying the groundwork to conduct the first study to measure how much less food you waste when you plan meals and shop from a tailored grocery list.
