This is something that comes up time and time again about food waste. A small amount of waste must be inevitable in journey form field to table but we can all play our part by being mindful of our shopping habits especially with fresh produce as often we are faced with more in a pack than we really need or want which is one issue with convenience pre packed fruit and veg.
My favourite packaged fruit is a carton of raspberries and as they are quite expensive you don't get many in a carton so its easy to eat them before their sell by date.
Here's a link to the UnitedNations End Food Waste day for more info:
I find I have the odd potato leftover when I buy some more but often freeze a batch so there's no waste. And I'd say that my food waste is minimal especially as I have a compost bin so it doesn't have to be collected entailing more work and energy to dispose of. I also keep a good selection of frozen veg so I only cook what I want and this saves a lot of waste as they're ready to cook.
I'd really like to hear other members ways of not wasting food as we can all inspire and encourage one another with this as the amount of food wasted is around 14% and that would fill a lot of bellies.
