I don't often pass on items about books from new age publishers by hyped
authors promoting silver bullet cures via non-paleo nutrition.  But the
review here has a few gems, even if some aspects of the book itself may be
dodgy.  The message of the book would appear to be consistent with the
views of the Weston-Price crowd.

Some snippets from the review:

More than 400 species of lactic acid bacteria (LAB) have been identified,
which promote the production of lactic acid that removes detrimental
pathogenic bacteria from the system. ... By providing our probiotic
bacteria with a healthy food supply – ‘prebiotics’ - a flourishing
community is maintained throughout our gut that protects us against
numerous disease conditions. The prebiotics, fructo-oligosaccharides (FOS)
and galacto-oligosaccharides (GOS), available in common healthy foods,
encourage the proliferation of beneficial gut bacteria.
....
When an oral antibiotic is swallowed, beneficial bacteria are killed,
allowing yeast to grow unchecked in the intestines. Their tendrils poke
holes in the lining of the intestinal walls creating a "leaky gut." Yeast
can then escape and infiltrate other bodily tissues, causing suppression
of the entire immune system
....
The advantages of the natural probiotic route to good health for the
newborn, young and old alike are explained, beginning from the newborn
child receiving its first microbes through mother’s milk. However, the
mothers’ gut microecology is now thought to be imbalanced, so that the
health of a breast-fed baby’s gut today is comparable to that of a formula
fed baby of a generation ago.

The book was published in March 2005.
