Hope you are well these are some ways you can take action to stop food waste. 

• Try not to get the best-looking fruits and vegetables because if everyone just got the best looking ones then all the bad looking ones which taste just fine will be left to rot. They will be part of food waste. #️ choose “ugly”
• People in shops put “best by” and “use by” dates, which are actually to let you know by when it is ideal to eat. It is proven that eating food after the expiry date for a few days is safe. “Use by” means it's not the same quality after that date.
• Buying too much is not good if you don't eat all of the food you buy. Eat all the food you buy in the last visit to the supermarket before going again. Making a list might help to know what you will need every day for lunch, basically the ingredients and if you don't you might overbuy or buy things you don't need.
