Nutritional Value of Fish!

 

The diet you feed your dog determines his health
and life expectancy more than any other care!

Fish is as useful a source of animal protein as meat. The oily fish, such as sardines and salmon contain vitamins A and D in their flesh, whereas in the white fish these are only present in the fish's liver. The bones of sardines, whitebait and tinned salmon provide us with calcium and phosphorous. Since all fish contain protein it is a good body building food and oily fish is useful for energy and as a protective food. Because of its fat content, oily fish is not as easy digested as white fish and therefore not suited when cooking for the elderly.

Protein
Varies between species, from 12% - 25% per 100 grams, which is approx. 1/3 of an adults requirements. Proteins are needed by the body as they are made up of amino acids, fish contains most of the essential amino acids; arginine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threoline and valine. The only essential amino acid not found in significant amounts is tryptophan. Non essential amino acids are also present; cystenic, aspartic, serine, glumatic, proline, glycine, alanini, tyrosine and taurine. Taurine is mainly found in octopus, squid and other shellfish.

Oil and fat
Varies from species to species, ranging from 1 - 15%, but averages at 4%. These oils are mainly unsaturated fats and some are highly polyunsaturated.

Carbohydrates
Not found in fish but carbohydrate glycogen is found in shellfish.

Minerals
Phosphorous, fluoride, magnesium, iodine, calcium and potassium are found, while trace elements of iron, zinc and selenium can also be found.

Vitamins
Some of the B group is found in fish; thiamine, riboflavin and niacin. The liver of white fish contains vitamins A and D, while these vitamins can also be found in the flesh of oily fish.
