Answer:
Salty foods are those foods which contain significant amounts of salt, generally sodium chloride, as a preservative or flavoring agent.
Salt is popular as it enhances some flavors and subdues others. A good example of this moderation is Dutch "dubbel zout" or double salt licorice where the salt reduces the licorice taste. Almost every culture has salty snacks from North America's potato chip to Korea's dried seaweed treat "kim"
Almost all preserved hard sausages contain high levels of salt (pepperoni etc.) as do preserved meats like jerky, bacon, ham and salted fish. Meats may contain salts other than sodium chloride. Nitrates are added to preserve colors.
Added sauces (Soya sauce, ketchup, BBQ sauce, salad dressings, tom yum) all contain salt to enhance the flavor of meat or vegetables. Similarly garnishes (Parmesan Cheese, seasoning mixtures etc.) are designed to add their own flavor as well as saltiness
Few drinks ae salty, however liquid foods like soups, stews and chili may be heavily salted.
