What is the primary dietary source of sulfur?

The primary dietary source of sulfur is animal proteins. Sulfur is an essential mineral that plays a crucial role in various bodily functions, particularly in the synthesis of amino acids, which are the building blocks of proteins. Many amino acids, such as methionine and cysteine, contain sulfur and are found in high concentrations in animal-based foods, including meat, fish, eggs, and dairy products.

While fruits, vegetables, cereals, and dairy products do contain some sulfur, they lack the higher concentrations found in animal proteins. Understanding this context highlights why animal proteins are considered the primary source of sulfur in the diet, as they provide a more concentrated supply necessary for adequate bodily function.
