The Nutritional Benefits of Beef Blood
Beef blood is an ingredient that is often overlooked but contains an impressive array of nutrients. As interest grows in nose-to-tail eating and reducing food waste, more attention is being paid to beef blood and how it can be used to boost nutritional profiles.
Protein and Amino Acids
One of the biggest benefits of beef blood is its high protein content. A 100 gram serving provides about 17 grams of protein, containing all nine essential amino acids.
This makes beef blood an excellent source of complete, high-quality protein. The abundance of amino acids like lysine and leucine make blood especially good for building and maintaining muscle.
Iron
Beef blood is extraordinarily rich in the mineral iron. A 100 gram portion contains about 8.2 milligrams of iron, which is 46% of the recommended daily intake.
This makes blood one of the best food sources of iron. The heme form of iron in beef blood is also highly bioavailable, meaning the body can efficiently absorb and utilize it.
Vitamins and Minerals
In addition to protein and iron, beef blood contains a variety of other vitamins and minerals:
- Zinc - supports immune function and DNA synthesis
- Copper - required for red blood cell formation
- Phosphorus - involved in bone health and energy production
- Selenium - important antioxidant that protects cells
Beef blood also contains useful amounts of B-vitamins including vitamin B12, niacin, thiamin, and riboflavin.
Challenges of Cooking With Beef Blood
While packed with nutrition, beef blood has a unique taste and texture that some find unappealing. It also congeals quickly during cooking, making it difficult to incorporate into recipes.
Here are some tips for cooking with beef blood to maximize flavor and nutrition:
- Add acidity - lemon/lime juice helps balance the metallic taste
- Combine with strong flavors - chili, garlic, horseradish complement well
- Prevent clumping - whisk continuously over low heat
- Use immediately - coagulation happens quickly as it cools
Black Pudding
One of the most renowned foods made with beef blood is black pudding. This type of blood sausage has its origins in Irish, British, and Scandinavian cuisines.
Modern black pudding is made by combining beef blood with fat, cereal or oatmeal, and spices. This mixture is stuffed into casings and cooked to produce a hearty, iron-rich sausage.
Though it may not appeal to all palates, black pudding is embraced by many food cultures as both a culinary tradition and valuable source of protein, healthy fats, and vitamins.
Blood Tacos
Blood tacos are another traditional dish that makes use of beef blood. This food can be found in Mexican cuisine and various Latin American countries.
To make blood tacos, beef blood is gently simmered with onion, garlic, and lime juice to temper the taste. Corn dough is then used to make tortillas, which are filled with the cooked blood mixture and topped with condiments.
This provides a nutrition-dense taco filled with the protein, vitamins, and minerals supplied by the blood. Cilantro, onion, salsa, and lime wedges nicely complement the earthy flavor.
Blood Sausage Around the World
While black pudding and blood tacos are some of the best known beef blood foods, blood sausage can be found in various cultures globally. Here are a few examples:
- Morcilla - Spanish style blood sausage
- Verivorst - Estonian Christmas blood sausage
- Mykyrokka - Finnish blood pancakes
- Czernina - Polish sweet soup made with duck blood
There are endless ways that protein and iron-rich beef blood can be incorporated into entrees, soups, sauces, puddings, and more.
Benefits of Beef Blood for Anemia
Due to its exceptionally high iron content, foods containing beef blood can be a helpful dietary addition for those at risk of iron deficiency anemia.
Iron Requirements
Iron plays several important roles in the body - it carries oxygen in the blood, aids enzyme functions, supports immune health, and more. As such, adequate iron intake is essential.
The recommended daily amount is 8-18 mg, depending on age and biological sex. During growth spurts, pregnancy, and lactation iron needs increase.
Iron Deficiency Anemia
When the body lacks sufficient iron over an extended period of time, iron deficiency anemia can set in. This condition is characterized by low hemoglobin levels, fatigue, pale skin, headaches, dizziness, and shortness of breath.
Globally, iron deficiency anemia affects about 1.6 billion people. It can have detrimental impacts on pregnancy, child development, and workforce productivity.
Treating Anemia with Beef Blood
Foods containing highly bioavailable heme iron like beef blood can assist with raising hemoglobin levels in those suffering from iron deficiency anemia.
Regularly consuming dishes made with blood, such as blood sausage, blood soups, blood gravies, or blood-enriched meatballs, provides the iron the body needs to produce healthy red blood cells.
Pairing blood-based foods with vitamin C sources helps boost iron absorption even further.
Sustainability Impact of Beef Blood Usage
Making use of beef blood, rather than discarding it as a waste product, benefits sustainability and efficient food production in several key ways:
Economic Revenue
Traditionally, blood collected at slaughterhouses has been seen as an undesirable by-product. However, a growing market exists for beef blood as an export commodity.
Rather than incur waste disposal costs for the blood, processors can sell it to other companies who use it in various food products, fertilizers, and to produce plasma.
This represents a sizable economic opportunity - one estimate valued the global bovine blood plasma market at 140 million dollars.
Environmental Footprint
Diverting beef blood away from landfills or incinerators towards human food production has environmental advantages. Using what was previously considered biological waste reduces demands for resources needed to raise additional livestock.
Similarly, collecting blood at slaughter for use in fertilizers and soil amendments displaces less sustainable alternatives. This supports regenerative agriculture principles.
Food Security
With predictions that food production must increase by over 50 percent in coming decades to feed the growing population, making use of often discarded animal by-products boosts global food security.
Beef blood can supplement diets with its dense protein and nutrients. Combined with strong flavors, textures, and spices, blood-based dishes provide nutrition to expanding populations.
