Nutrients Provided by Fish

Fish provide some very important nutrients to our diet. They provide an alternative source of (high biological value) protein and "good" fat.

A 3 1/2 ounce serving of fish provides a good source of:

  • Niacin
  • Vitamin B6
  • Vitamin B12
  • Vitamin E
  • Phosphorus
  • Selenium

Fish is also a fair source of:

  • Potassium
  • Magnesium
  • Iron

Avoid Sources of Fish or Fish Products

Typically fish is not a hidden ingredient in foods, however, some foods which contain fish or fish products are:

  • Caesar salad
  • Caviar
  • Roe
  • Worcestershire sauce (if it contains anchovy)

It is usually recommended that fish-allergic people avoid all species of fish. Blended food challenges may be helpful to determine which fish are safe.
