Green tea, mushrooms, miso… why does the Japanese diet promote women’s longevity?

Green tea, seaweed and fish… This menu prevents brain atrophy with age, leading to dementia or cognitive decline. One study points to the Japanese diet as the key, but it only works for women.

It’s no secret: Japan, particularly Okinawa, located in the far south near Taiwan, is home to some of the world’s most famous centenarians. The paradise Japanese archipelago concentrates a large number of elderly people who have survived the age of one hundred years of life. In addition to their mental health and active lifestyle, as noted by Japan Airlines, we also know that their diet contributes to their longevity. Vegetables and all kinds of plants, as well as rice, fish and even seaweed… This is the menu of these famous centenarians, but in fact they are not the only Japanese who follow this diet.

Eating habits

The Japanese adopted this too! And this is good, because such eating habits prevent brain atrophy as we grow older. As we age, cognitive decline or even dementia are indeed consequences of brain atrophy. We’re talking about Japanese women, not men, whose brains don’t receive the same protective benefits, reports a study published in Nutrition Journal.

A total of 1,636 guinea pigs aged 40 to 89 years took part in this study, supported by the National Center for Geriatrics and Gerontology of Japan and the University of Liverpool in the UK. The participants’ diets were monitored for two years, revealing three main types of menus, including a Western diet, another based primarily on vegetables, fruits and dairy products, and finally a traditional Japanese diet. The secret to good cognitive health, ladies, thus lies in drinking green tea, mushrooms or even miso, the famous fermented soybean paste that forms the basis of the recipes, complemented by umami (the fifth taste).
