[Machine Translation] The reason why Japanese people's immunity is generally declining is because they do not take good care of their intestines. The civilized society that modern people have built for their own good is clean, convenient, and saturated with food. This comfortable society has weakened the intestines. Cancer patients may have increased rapidly in a lifestyle that lowers the immune system. So, how can we regulate our intestines and enhance our immunity? This book introduces in detail how cancer occurs, how to prevent it, and how to keep it away.
