Canned oysters usually come in smoked or natural varieties. Smoked oysters have a delicious smoky flavor, but they're typically packed in oil and can be high in fat.
Oysters are packed with nutrients, making them a great protein choice. They're also low in calories and fat — as long as you stick with water-packed varieties.
Fresh oysters will only last a few days in the fridge, but canned oysters can last years if properly stored. When it's time to eat, all you have to do is pop the top and enjoy.
