Description:

From the greatest medical team ever assembled. As of today, over 600 great doctors and scientists have now volunteered to join this lifesaving project, to end the most dreaded diseases of our time. And their new information is so life-changing, we had no choice but to create a completely new blockbuster. Hardcover, with 576 pages of astonishing new cures, treatments and preventives for heart disease, cancer, arthritis, diabetes, memory problems, nearly any kind of chronic pain, and so much more. It had to be so huge, because this medical team has made thousands of new breakthroughs. Bottom Line's cure-finding team now includes 3 Nobel Prize winners. Plus winners of the National Medal of Science and The Linus Pauling Award. Plus top doctors and researchers from nearly all of America's greatest universities and research hospitals. They all volunteered without pay, so that your loved ones could get well again.

I have a Ph.D. in Health Communication.  I bought the book. Very interesting.  It's a compendium of health related and medical books and peer reviewed journal article results on a variety of topics that interest me, thyroid, stroke, alzheimer, arthritis, insulin, weight gain/loss, ear wax, hearing, eye sight.  You can read the results of the studies wihtout having to go to a medical library and getting the information.

It's 543 pages without the index.  I find it to be a very good reference. Now, it is not exhaustive.  topics such as weight loss at various ages, say 20'2, 40's 60's for both premenopausal and post menopausal women is not there (I have not fund it), but I found a study using food scents for losing weight, participants in the studey loss 30 lbs on average over a 6 month period! 

Yes, I will recommend it. It's not an Encyclopedia, keep that in mind.
