The Japanese diet, characterized by balance, mindful eating, and a focus on whole foods, has been linked to good health outcomes and longevity. It has shown effectiveness in preventing and treating fatty liver disease, a condition characterised by excessive fat buildup in the liver. The diet’s emphasis on whole, plant-based foods, such as vegetables, fruits, whole grains, and legumes, provides essential nutrients like fiber, antioxidants, and omega-3 fatty acids that help prevent inflammation and liver damage. The practice of mindful eating, known as hara hachi bu, also contributes to weight management and reduced calorie intake. By limiting red meat, processed foods, and sugar while consuming complex carbohydrates with a low glycemic index, the Japanese diet stabilises blood sugar levels, reducing the risk of fatty liver. Overall, the Japanese diet offers a nourishing approach to liver health and overall well-being.
