Country with the highest life expectancy - it's all down to their diet
Ever pondered why some nations have a longer life expectancy than others? Japan tops the list of G7 countries when it comes to life expectancy at birth, meaning that on average, folks there outlive those in Canada, France, Germany, Italy, the UK and the US. An expert has shed light on how diet plays a significant role in these stats.
The elevated life expectancy is largely down to fewer deaths from ischemic heart disease and cancers, which can be attributed to a lower obesity rate, less consumption of red meat, and higher intake of fish and plant-based foods. Dr Martin Juneau, a cardiologist, highlighted the crucial role diet plays in the longevity of the Japanese population.
The heart specialist pointed out that the Japanese consume far less meat, dairy products, and sugars, but more fish, seafood, rice, soybeans, and tea. For instance, the Japanese eat nearly half as much meat as Canadians do, but twice the amount of fish and seafood - and a higher intake of omega-3 fatty acids is linked with a reduced risk of ischemic heart disease.
Japan's low obesity rate also plays a pivotal role, as obesity is a significant risk factor for ischemic heart disease and several types of cancers, Dr Juneau elaborated. One reason Japan has a low prevalence of obesity-related diseases is because its people consume relatively fewer sugars and starches compared to other nations, reports Surrey Live.
Okinawa, a Japanese island at the country's southern tip, is renowned as a "Blue Zone" where folks enjoy some of the world's longest lifespans. Dan Buettner and his research team have found out that not only do Okinawans suffer less from cancer, heart disease, and dementia compared to Americans but also the island's women live longer than any others across the globe.
The secret to their enduring health? A plant-heavy diet, according to Buettner, whose insights reveal that local diets are brimming with nutrient-rich, low-calorie staple meals such as stir-fried veggies, sweet potatoes, and tofu.
The longevity expert pointed out that the consumption of soy-based foods like tofu and miso soup plays a significant role in ensuring healthy living. These fermented titbits help keep the digestive system in check and tofu's flavonoids could be vital in protecting the heart and combating breast cancer.
Physical activity through gardening keeps Okinawans sprightly, providing an abundance of fresh veggies while their minimalistic homes encourage frequent sitting down and standing up, bolstering the lower body strength and balance of the elderly.
