This section deals with the major nutrients  (macronutrients) supplied by seafoods. Protein and fats/oils are the  only major nutrient groups supplied by seafoods. The other major macronutrient type, carbohydrate, does not feature prominently in seafoods, and will not be further discussed here.

Fish

Nutritionally, the demersel group mainly provide protein, with 80-90% of food energy deriving from this. Lipid levels are 0-2%. Carbohydrate is virtually absent in significant amounts from all bony fish commonly eaten. Levels (in g/100g) of protein in pelagic fish are similar to those in demersel fish (see table below), but lipid levels of 5-15g/100g mean that a smaller proportion of food energy is derived from protein when pelagic fish are corollary of this is that overall food energy intake is higher from pelagic fish than from demersel fish. The higher lipid level in such fish is the reason the are often referred to a fatty fish, oily fish or oil-rich fish.
