Japanese women and men currently live five to six years longer than Americans, so their practices are of great interest. In Japanese families, elders are highly revered and households are intergenerational. Japanese elders are generally healthier than Western elders, but is this the chicken or the egg? Does better health from good lifestyle habits allow them to stay physically active and involved in society so they remain a valuable asset and reap psychosocial benefits, or is it the culture that reveres elders so they have better mental health, less loneliness, and better healthcare so that they stay healthier longer? Japan has also largely avoided the epidemic of obesity that the U.S. is experiencing; for example, the prevalence of obesity among U.S. women is about 37% but among Japanese women is less than 5%. [24] This difference is certainly an important contributor to differences in life expectancy, but raises questions about how the Japanese have been able to control their weight. In recent years, diets in Japan have become more similar to those in the U.S. but they still eat smaller portions, more fermented foods, less sweets, and less red meat.
