Over 30 years of feeding the healthy and the sick, the weak and the strong, the young and the old have shown me that a change in nutrition, in the sense of the correct combinations is immediately a sign of improved health. It is the consequence of the lightening of the burden borne by the digestive organs allowing better nutrition and less poisoning. I have noticed that such correct meals are followed by less fermentation and putrefaction, a reduction in the presence of gas and sickness.
