Beef bone marrow is a traditional ingredient in certain cuisines, such as Vietnamese or French. Beef bone marrow is the fatty and gelatinous matter inside large beef bones. The marrow becomes soft when roasted, and you can spread it on toast, use it in sauces or use it as a garnish. Beef bone marrow is high in certain nutrients, but it is also high in fat, so regular consumption can be dangerous for your health.
A 1/2-ounce serving of beef bone marrow contains 125.59 calories. Because beef bone marrow is so rich and high in fat, a serving is smaller than a serving of other common protein items such as steak or fish. Bone marrow is rarely eaten on its own. Instead it is commonly served as a spread with toast or as a garnish to other dishes such as roast fish. This means that when you eat one serving of beef bone marrow, you usually also are eating other foods as part of the dish, and you need to account for those calories as well.
