Refrigerated food is not bad for health.
Refrigeration of food is very necessary as if you don't refrigerate certain foods then bacteria can grow in the food and make you sick.
However the longer food remains refrigerated or frozen the less nutritious the food becomes but it's still healthy to eat the food that has been refrigerated.
The crisper drawer in the fridge is the drawer that the vegetables go in.
The difference between a crisper drawer and a fresh drawer in a fridge is that the fresh drawer keeps foods at the lowest temperatures possible without freezing them while the crisper drawer helps keep high moisture foods fresh.
Foods that go in the fridges crisper drawer are either fruits or vegetables.
Crisper Drawers set to low-humidity (sometimes labeled the “fruit” setting) lets out some of the ethylene gases that lead to faster rotting.
The crisper drawer keeps fruits and vegetables fresher and keeps the fruits and vegetables from rotting as fast so they last longer and stay fresher longer.
Some foods that go into the crisper drawer are foods such as apples, pears, avocados, melons or stone fruits.
Carrots, potatoes, lettuce, celery etc can also go into a crisper drawer.
Basically any foods that you want to keep fresher longer and prevent rotting as fast those foods go into a crisper drawer.
I keep foods such as celery, carrots, potatoes, lettuce and other fruits and vegetables in my crisper drawer.
