PREbiotics, not Probiotics

The book is divided into three sections. The third is an autobiography of the author, Frank W. Jackson MD. The second section is all about the difference between prebiotics and probiotics and their importance. This section is very interesting and informative. But the first section is a shamelsss advertisement for the product that the author has developed and sells to improve the state of the the gut. The product is also mentioned many, many times in the second section.
