Which of the following is a dietary source of riboflavin?

Riboflavin, also known as vitamin B2, is an essential nutrient that plays a significant role in energy production and the metabolism of fats, drugs, and steroids. One of the best dietary sources of riboflavin is eggs. Eggs contain a substantial amount of riboflavin, primarily in the egg white, making them a rich source for those looking to increase their intake of this vitamin. They are not only nutritious but also versatile in culinary uses, contributing to various diets.

The other foods listed, while healthy options, do not provide riboflavin in as significant amounts. Chicken breast, although a great source of protein, contains riboflavin but to a lesser extent compared to eggs. Broccoli offers other nutritional benefits and vitamins but is notably lower in riboflavin than eggs. Corn, while a good source of other nutrients, does not contribute meaningfully to riboflavin intake. Thus, eggs stand out as the primary and richest dietary source among the options provided.
