Which of the following is a source of folate?

Folate, also known as vitamin B9, is crucial for various bodily functions, including DNA synthesis and repair, cell division, and overall growth. The primary food sources of folate are typically found in foods that are rich in leafy green vegetables, legumes, and certain animal products. Liver, particularly beef liver, is one of the richest sources of folate. It contains a high concentration of this essential nutrient, making it an excellent dietary choice for individuals looking to increase their folate intake.

While fish, eggs, and butter have nutritional benefits, they do not provide significant amounts of folate compared to liver. Fish and eggs might contain some B vitamins, and butter is primarily a fat source, lacking in folate altogether. Therefore, liver stands out as the best and most concentrated source of folate among the given options.
