Why soybeans?

In many Chinese “longevity villages,” elderly people consume tofu almost daily.

(Oats, millet, brown rice, barley, sorghum, etc.)

Ranked third, sweet potatoes are considered one of the world’s healthiest foods by the WHO.

In regions with exceptional longevity, such as Okinawa and parts of China, sweet potatoes are eaten almost every day.
