Recent research underscores the critical role of diet in determining longevity. A study led by Lars Fadnes at the University of Bergen analyzed data from the Global Burden of Disease Study, revealing that typical Western diets contribute to 11 million premature deaths annually. By switching to a healthier diet rich in whole grains, fruits, and vegetables, individuals could significantly increase their life expectancy—up to 89 years for a 20-year-old woman in the U.S. The study also highlighted that centenarians often consume balanced diets low in salt and high in nutrients. Additional research from Harvard found that those adhering to Mediterranean-style diets throughout middle age were more likely to age healthily. While calorie restriction is known to extend lifespans in animals, its effects on humans remain unproven. Overall, dietary choices are pivotal for achieving longevity and maintaining health in later years.
