2. Anchovies

Anchovies are small, saltwater fish that are classified as oily fish and are often available preserved in oil or salt. They are a popular ingredient in various gourmet sauces including Worcestershire sauce, versions of Café de Paris butter and Caesar’s salad dressing, and are also used as pizza toppings in some places. Unfortunately, as appetizing they may sound, anchovies are known to be rich in purines and should be avoided by people suffering from gout.
