As interest in the nutritional value of food intake, including digestion and absorption rates, rises, Hanwoo beef is gaining recognition as a high-quality protein source.
According to the Hanwoo Promotion Fund Management Committee, the Ministry of Health and Welfare and the Korean Nutrition Society have adjusted the recommended energy ratio for protein intake in the '2025 Nutrient Intake Standards for Koreans' from the previous 7-20% to 10-20%.
The key criteria for evaluating protein quality are the composition of essential amino acids and digestibility. Hanwoo beef contains all nine essential amino acids, including leucine and lysine. Among these, leucine plays a crucial role in muscle protein synthesis. The protein consumed from food is broken down into amino acids during digestion and is then utilized to form and maintain body tissues such as muscles, organs, and skin.
The protein content in Hanwoo beef varies depending on the cut and cooking method, but it averages about 20g per 100g. Additionally, it contains heme iron, which has a high absorption rate, as well as zinc, which is necessary for maintaining normal immune function, and vitamin B12, which is involved in nerve function and red blood cell formation.
Research is also being conducted to examine the functions of bioactive components found in Hanwoo beef. Some experiments targeting specific components of Hanwoo sirloin have observed effects in inhibiting the production or expression of inflammation-related factors such as nitric oxide (NO) and TNF-α. Studies have also investigated the impact on inflammatory responses related to colitis and the proliferation of colon cancer cells.
However, these results have been confirmed under specific experimental conditions, and further research is needed to determine whether anti-inflammatory and anti-cancer effects occur in the human body.
Professor Park Gyu-hyun from Kangwon National University, an honorary ambassador for the Hanwoo Promotion Fund, stated, "In today's world where protein intake is commonplace, the key to health management lies not just in the quantity consumed but in how well it is digested, absorbed, and utilized by our bodies. Hanwoo beef is a high-quality protein source that provides all nine essential amino acids along with various micronutrients, which can aid in nutritional management through a balanced diet."
