Nutritional Content of Canned Oysters
If you are looking for healthy, convenient foods to boost your nutrient intake, consider adding canned oysters to your meal plan. These shellfish are nutritious additions to salads, soups and other dishes. Canned oysters are not only quick to prepare, but because they are already cooked, they are also safer choices than raw oysters for preventing food-borne illnesses.
Calories and Macronutrients
A 6-ounce portion of canned oysters has only 116 calories, so they can help you lose weight or maintain a healthy weight. Oysters have 12 grams of high-quality protein. Unlike fish and some other kinds of shellfish, such as shrimp, oysters are a natural source of carbohydrates, with 6.6 grams of carbs per serving. They have 6 grams of total fat, including 1 gram of saturated fat. Oysters do, however, contain 94 milligrams of cholesterol. This makes up roughly one-third of your daily cholesterol limit, or one-half if you suffer from high cholesterol or heart disease.

Omega-3 Fatty Acids
Sodium & Oysters
Canned oysters come packed with omega-3 fatty acids. A 6-ounce serving of canned oysters supplies 358 milligrams eicosapentaenoic acid, or EPA, and 388 milligrams of docosahexaenoic acid. These omega-3 fatty acids might lower your risk for heart disease when you average a total combined intake of at least 250 milligrams per day, according to the 2010 Dietary Guidelines from the U.S. Department of Health and Human Services. Just one serving of oysters provides almost one and a half times this intake goal.

A 6.ounce serving of canned oysters supplies 154 mg zinc, or 1026 percent of the daily value. Zinc is an essential mineral for your immune system, and adequate intake might lower your risk for age-related macular degeneration, according to the Linus Pauling Institute Micronutrient Information Center. Individuals at higher risk for zinc deficiency include strict vegetarians who do not consume animal products, older adults and individuals with nutrient malabsorption conditions. Canned oysters are so high in zinc that you should actually watch out for a zinc overdose if you consume them on a regular basis -- they contain more than the upper daily limit, which is 40 milligrams for adults. Avoid eating canned oysters every day to prevent a toxicity.
