Inspired by my uncle, I tried a no-salt, no-sugar diet.
My uncle, Shoichiro Nakao, is a cardiologist, and after studying at Harvard Medical School, in 1995, he published a paper in the medical journal NEJM on Cardiac Fabry Disease, which was published from Japan to the world, and he is an amazing person. There is probably only one person in Japan who is so strictly salt-free and sugar-free.
