Squid is a type of seafood often eaten fried and called calamari. You also can steam squid and add it to pasta or prepare it raw for sushi. While most of the vitamin and mineral content is similar between raw and fried squid, the calorie and fat content of fried squid are much higher.
A 3-oz. serving of raw squid contains 78 calories, composed of about 70 percent protein, 15 percent carbohydrates and 15 percent fat.

One serving of fried squid is about 40 percent protein, 40 percent fat and 20 percent carbohydrates.
One serving of raw squid contains only 1.2 g of fat, less than .5 g of which is saturated fat. However, like other seafood, such as shrimp, raw squid is high in cholesterol, with 198 mg per serving.
