Beef - SweetbreadBeef sweetbread is a type of organ meat that comes from the thymus gland and pancreas of a cow. Despite its name, it is not a bread but rather a culinary term for this specific type of organ meat. Beef sweetbreads are a rich source of protein, vitamins, and minerals, including zinc, iron, and vitamin B12. However, because they are a high fat cut of meat, they should be consumed in moderation as part of a balanced diet.
