Kelp and spirulina are two different types of seaweed that are good for human consumption. They can be eaten both raw or dried; they can be blended into smoothies, mixed into salads, or included in many other baked or cooked dishes. The two seaweeds contain different quantities of various nutrients, so in many cases a mix of both provides the most complete nutrition.

Calories, Fat, Cholesterol and Sodium

One 100 gram serving of raw kelp contains 43 calories, while the same serving of raw spirulina contains only 26 calories. There are 0.56 grams of total fat and 0.25 grams of saturated fat in the kelp, and 0.39 grams of total fat and 0.14 grams of saturated fat in the spirulina. The kelp contains 233 milligrams of sodium, while the spirulina contains 98 milligrams of sodium. Consumption of more than 2,300 milligrams of sodium per day can lead to an increased risk of high blood pressure complications, according to University of Maryland Medical Center.

Carbohydrates, Fiber and Protein

Each serving of kelp contains 9.57 grams of carbohydrates, 1.3 grams of dietary fiber and 1.68 grams of protein; each serving of spirulina contains 2.42 grams of carbohydrates, no fiber and 5.92 grams of protein. According to the Harvard School of Public Health, your body uses protein to repair and maintain itself; for example, when you work out your muscles, your body needs protein to rebuild them.
