A 3-ounce serving of medium-sized shrimp contains a negligible amount of carbohydrates, usually between 0 and 1.5 grams. The size of the shrimp, serving size and any sauces added change the amount of carbohydrates.
A 3-oz serving of shrimp also contains 100 calories, 1.4 grams of fat and 20 grams of protein, which makes shrimp a healthy food choice. Shrimp are somewhat high in sodium because they come from sea water, but seafood also contains healthy minerals such as selenium that can be difficult to consume from other foods.
Breading, cocktail sauces and other condiments can add a substantial amount of carbohydrates to an otherwise low-carb food.
