Benefit of Japanese Diet on Longevity and Chronic Diseases and Its Challenge

Abstract

Japanese life expectancy at birth in 2016 is the highest in G7 countries. The Japanese diet is renowned for its association with longevity and reduced risk of chronic diseases. Featured by a balance of fresh, seasonal ingredients, predominantly plant-based with moderate consumption of fish and meat, this diet offers various health benefits. Rich in nutrient-dense foods such as fish, seaweed, vegetables, and fermented soy products, it provides essential vitamins, minerals, and antioxidants crucial for people. The emphasis on fish, particularly fatty fish like salmon, welcomed best by Japanese, supplies omega-3 fatty acids, which are known widely because of their anti-inflammatory properties and cardiovascular benefits. Additionally, the inclusion of fermented foods promotes gut health, bolstering the immune system and reducing the risk of gastrointestinal issues. With less-processed foods and added sugars, the Japanese diet can effectively regulate healthy blood sugar levels and reduces the risk of obesity, diabetes mellitus, and cardiovascular diseases. Its holistic approach to nutrition underscores the profound impact of dietary choices on longevity and the prevention of chronic diseases.
