The mortality rate from coronary artery disease ("CAD") in Japan is significantly lower compared to other developed countries, and this is due in part to the influence of Japan's diet. A number of epidemiological studies have demonstrated the efficacy of a diet that may be described as ‘traditional Japanese diet' ("Japan Diet"), which utilizes ingredients native to Japan, in the prevention of CAD. The Japan Diet primarily sources saturated fatty acids from meat (beef and poultry), monounsaturated fatty acids from meat, fish, and vegetable oils, n-6 polyunsaturated fatty acids from vegetable oils and soy products, and n-3 polyunsaturated fatty acids from marine products and plants. The Japan Diet is characterized by a higher consumption of fish and soybeans/soybean products compared to meat and eggs. Additionally, the intake of fatty acids is balanced in a manner that is conducive to the prevention of arteriosclerosis.
The Japan Atherosclerosis Society has been formulating guidelines for the prevention of arteriosclerosis since 2007. The 2012 revised edition was formulated with the goal of providing nutritional guidance to improve risk factors, with the goal of understanding the lifestyle of each patient, including their nutrient intake, before providing guidance. In the 2022 editions, 11 clinical questions were created for guidelines on dyslipidemia and related conditions in nutritional therapy, and recommendations were made primarily based on randomized controlled trials when making decisions about medical procedures in clinical settings, with important clinical issues being raised that are expected to improve patient outcomes.
