Life expectancy is highest in the world in

Japan consistently records the highest life expectancy in the world due to a combination of factors including a healthy traditional diet, a robust public healthcare system, and a high standard of living. The Japanese diet is typically low in processed sugars and fats while being rich in fish, vegetables, and fermented foods, which contributes to lower rates of obesity and cardiovascular diseases. Additionally, Japan has comprehensive health screening programs and a strong cultural emphasis on physical activity and social integration among the elderly, allowing a significant portion of its population to live well into their eighties and nineties. While countries like Norway, Canada, and Germany also have high life expectancy, Japan historically leads global rankings.
