Wardlaw's Perspectives in Nutrition - Carol Byrd-Bredbenner, Jacqueline Berning, Donna Beshgetoor, Gaile Moe Ongoing review.Chapter One, 'The Science of Nutrition,' Two, 'The Healthy Diet,' Three, 'The Food Supply,' and Four, 'Human Digestion and Absorption' should probably be read by everybody with a body. 'Healthy Diet' overviews what constitutes a good diet and way, and helps define empty calories, the over-emphasis of animal proteins in U.S./Canada in contrast with the majority of the world, and the prevalence of 'food insecurity,' a concept developed to categorize the awful phenomenon of people who aren't sure where their next meal is coming from but who aren't technically 'starving.' 'Food Supply' is a nice overview to the way food makes its way to the table/restaurant that includes genetic modification in food, storage issues, irradiation, and food-borne illnesses. 'Digestion' is a fast, solid review of anatomy and physiology, written at high-school level. For those that might want a little more detail, there is a detailed appendix about the digestive process, including some hormone feedback systems and chemistry.I found the text very current with lots of citations (always appreciated in such a constantly changing field), with multiple links for those who wish to fact-check or explore certain issues further. I liked the acknowledgement of the cultural aspect of appetite, a challenging topic in many levels as to what constitutes 'food,' and its importance in rituals and celebrations. Visually, there is a nice variety of graphics that make it more accessible to more visual learners. I also appreciated the way it includes nods to potentially controversial issues like gluten sensitivity, antibiotic overuse and organic foods. What I've learned so far is a lot, but fun factiods:The stomach can vary in size from 50 mL when empty to 1.5L when full to 4 L when very, very full (and probably over-conditioned!)We pass anywhere from a pint to 4 pints of gas a day.Take that, Mary Roach!
