Which of the following foods is a good source of vitamin D?

Fatty fish and eggs are excellent sources of vitamin D due to their rich nutritional content. Vitamin D is a fat-soluble vitamin that plays a crucial role in various bodily functions, including calcium absorption, which is essential for maintaining healthy bones. Foods such as salmon, mackerel, sardines, and fortified eggs provide substantial amounts of vitamin D, which can help individuals meet their daily dietary requirements.

In contrast, fresh vegetables, whole grain bread, and fruit smoothies generally provide negligible amounts of vitamin D. While these options are packed with other vital nutrients, they do not significantly contribute to vitamin D intake. Therefore, choosing fatty fish and eggs is a wise decision for those looking to enhance their vitamin D levels through diet.
