I just finished reading the 147 page book No Guts, No Glory: Gut Solution- The Core of Your Total Wellness by Dr. Steven Lamm MD and Sidney Stevens.
It was nice to read a book that covered a lot of ground but wasn't too bogged down with intensive data. Plenty of reputable research was cited, but the message of the book was more that we need to start paying attention to the wellness of our guts, instead of focusing solely on seemingly random symptoms and pain. The book is an overview of the complexity of the system, whatever you want to call it, that digests our foods, greatly influences our moods, hugely impacts our immune function, and generates our life-force and vitality. He refers to it as the "Gut."
There is a plan for improving our gut's functionality, but again, it was all phrased as a wake up call, more than a strictly scheduled diet and health regime, like so many self-help style books include. The tenets of the plan are eating foods based on highest nutritional content and least damaging content, detoxification from environmental and food sourced pollutants, use of enzymes, pre and pro-biotic supplements, and overall stress management.
The biggest eye opener to me was how the trillions of microscopic organisms inside our GI tract work symbiotically with our body to form an "Intelligent" system. When we take a course of antibiotics, they can wipe out years, even decades, of built up immune function inside that system. Research is leading doctors away from widespread antibiotic use, in favor of strengthening the beneficial bacterium in the gut, to promote the greatest health in their patients. If you have one weed growing in the middle of a golf course full of healthy turf, you don't use agent orange to kill it. Instead, you could fertilize the healthy grass more and don't water the weed.
There was also some talk in the book about the gut/brain connection. Research is still preliminary here, but so far the inner workings of our neurological functioning and how it creates the huge range of human feelings and emotion could all be tied to the interplay of food, our guts, and our brains. Fascinating stuff.
Overall, definitely worth the couple hours of informative reading.
