Use tender vegetables like broccoli, lettuce and mushrooms early in the week and root vegetables nearer to the end.
Most fruit is best stores in a bowl where air can circulate but store berries in the fridge.
Take all Fruit and Vegetables out of plastic bags as soon as you get home, this way they will keep longer. Vegetables are best stored in a cool, ventilated place out of direct sunlight. Always wash Fruit and Vegetables just before eating. Where possible don't peel, as you will lose some vitamins. Try to prepare vegetables just before cooking as cutting speeds up the loss of vitamins.
