Not all food goes in the fridge
The best place to keep your onions, potatoes and bread are in cool dark places. They will last a lot longer by storing hem this way compared to storing them in the fridge.
Be smart when storing food
Make sure you store your food in the most appropriate ways so they last longer. Leftovers can keep up to 2 days in the fridge well wrapped. Most fruit and vegetables will stay fresh for longer if stored in the fridge. Also, fresh foods once opened will stay fresh for longer if wrapped well or stored in air-tight containers.
Temperature of your fridge
Keep your fridge between 1-5°C. This will ensure that the temperature will slow the growth of bacteria without freezing your food.
