The suggestions are very beneficial even though they are very common known things. I have a disappointment for the research section: The statistics doesn't say me anything but just numbers since the references are not stated as a footnote... Particularly, I loved the 23rd topic which is about tomato. As a being tomato hater, I just become very excited when it is claimed that the cooked tomato might be 2.5 times beneficial to the raw one comparing their lycopene amounts! Overall, the book is O.K but I cannot assert it's worth to read it...
