reginadelmar’s #CBR5 review #52 In Defense of Food: An Eaters’ Manifesto by Michael Pollan


I am a fan of Michael Pollan, having read several of his books and heard him speak when he’s in town. I hadn’t read In Defense of Food because I heard him interviewed and attended a lecture right around the time the book was published. At the lecture he brought a shopping bag full of things he’d picked up at a grocery store: green tea infused sodas, yogurt with fiber added, and numerous other manufactured foods. His point was that in the United States we practice “nutritionalism” focusing on particular nutrients rather than whole foods, and eating manufactured foods in the process. This is the theme of the book.  Pollan goes through a history of food science, a description of what we are eating today, and his suggestions for a better way of eating.

The phenomenon of nutritionalism was named in the late 20th century, but has been in practice since the 19th century. Currently the popular “bad” nutrient is the carbohydrate. Athe end of the 20th century it was fat, in the 19th and early 20th century, John Kellogg and others extolled the harm of animal proteins. In general, our food research seeks to isolate certain nutrients and determine their harmful or beneficial effects. This isn’t all bad, science has discovered vitamins and other minerals in food and determined they were necessary. The problem is that this form of reductionism also creates over simplifications in our approach to food. Continue reading

Lollygagger’s #CBR5 Review #52: Good Calories, Bad Calories by Gary Taubes



It seems appropriate that I finished this book over Thanksgiving weekend, given our national propensity towards eating a fair bit more than usual during this time. I’d seen this book on the shelves at the bookstore before, and ignored it because it seemed like another cheesy diet book. After a friend described it as a book that made her actively feel smarter, I picked it up.

Before I get into the book, I want to point out that people can be fat for many reasons (as the book will show), and that moreover it is absurd to suggest – as society so often does – that one has to lose weight or become skinny to have value (or to be healthy). Lots of people want to say that fat people are unhealthy because they are fat, but when it comes down to it you really can’t usually tell if someone is healthy simply by looking at them or if you know their height and weight. Moreover, I don’t think anyone owes it to anyone else to be healthy. I think everyone should have access to things that can help them be healthy, but I don’t think anyone owes ME their health. And yes, that includes fat people who some think cost the healthcare system more. First off, they don’t, but secondly, if we’re going to start requiring fat people to lose weight because they might cost us more in health care, then there are a whole lot of other people (people who drive, people who ride in cars, people who smoke, people who ski and might break a leg, people who play professional football) who apparently need to change their behaviors because we think they might cost us more. Alright. On to the review.

The next time you’re around family discussing weight loss, obesity, or anything really related to diet and nutrition, and someone (usually smug, usually skinny) says “it’s a simple matter of physics: calories in has to equal calories out or you’ll gain or lose weight,” hand him a copy of this book, and tell him to not comment on such things until he’s read the whole thing. In addition to possibly contributing to his education, it’ll have the added benefit of shutting him up, because no one wants to hear from that douchey cousin anyway.

Mr. Taubes’ purpose with this book is to examine as much of the science behind weight gain / loss and the diseases that tend to be associated with it as possible. He’s not so much interested in proving or disproving any one hypothesis; he’s interested in seeing what is out there from the last 100+ years and trying to figure out if any of the conventional wisdom we hold regarding weight, nutrition and health stands up to scrutiny. It turns out much of it does not.

There is so much in this book that I can’t cover in this review (especially the discussion on why cholesterol tests may be measuring the wrong thing and ultimately not telling us what we think they are – I need to re-read that section to really understand it), but I wanted to pull out some interesting bits. While looking at some weight studies that have been done, Mr. Taubes pretty quickly dismisses the idea that people are fat because they ‘overeat’ (in fact he repeatedly uses many different studies to fight off this repellant ‘lack of willpower’ argument). The most interesting ones were the studies that had people eating the exact same diet and exerting the same amount of energy (usually these were prison inmates and thus easily tracked) and showing that across the board, some people gained weight, some stayed the same, and some may have lost weight. And among those gaining weight, some would gain two pounds, some would gain 10 or 15. Yes, those are just a few studies, but it does hold up when you think about the people you might know who seem to eat as much as or more than you and yet never gain any significant weight, while you might eat 1,500 calories a day, work out for 30 minutes six times a week, and struggle to fit into a size 16 pants. The question then becomes WHY does this happen?

Another interesting discussion revolved around exercise, and how it may have many health benefits, but that weight loss is not likely among those benefits. I’d read articles about this before; the thinking is that yes, you work out and burn some calories, but the attendant rise in hunger will usually cancel out any weight loss based solely on activity. Let’s say you work out on the elliptical for 30 minutes more than usual and burn and extra 250 calories; just off of the hunger that a workout can produce you might consume that extra 250 with a single Cliff bar on the walk home from the gym. The author is not saying that exercise doesn’t have health benefits; only that those benefits don’t necessarily include weight loss.

It’s so interesting that many of the studies, if properly interpreted, provide very different conclusions than the ones the authors of them – and the policy wonks who reference them – concluded. That then leads to a whole lot of confirmation bias – people looking for support for answers they already have decided are correct and only conducting studies or referencing studies that support the answers they want. So you get one study that claims that fat is bad (but doesn’t actually properly measure that); common sense says well, people who are fat have a lot of fat, so duh, eat less fat to have less fat, and the wheels are set in motion. But what Taubes’ meta-research shows is that it is not fat that makes people fat and keeps people from a lower weight, but simple sugars and carbohydrates.

That’s right – the data (annoyingly) seems to overwhelmingly support the ideas that those obnoxious Atkins / South Beach / no carb diet books promote. Sort of, although not necessarily for the reasons those book site. Taubes’ understanding of the research out there suggests that what matters is not necessarily the amount of energy we consume (via food) but the type we consume that impacts the energy that is available to us, and the consumption of carbohydrates (think flour and potatoes, not the kind found in veggies and fruits) hinders the ability to make use of the energy we already have stored in our body, while also adding to those stores and increasing our fat. The book goes into a lot of detail and is very dense, so it’s hard to synthesize it down to this review (he’s apparently followed this book up with a book targeted more at the average reader, not science readers). But I am going to say that the argument he makes was really convincing to me. There’s so much more to say, but this review is already silly long, so if you’re interested (or screaming NO YOU’RE WRONG while reading this), then pick up the book.

As I said, this is NOT a diet book; however, the epilogue does offer his thoughts on what he thinks his meta-research has shown and what that means for people who want to maintain certain weight levels and stave off some diseases (the section on sugar and diseases is enough for me to seriously contemplate giving up added sugar completely), but he points out that there is so much more research that should be done and IS NOT being done because society assumes it already gets it. It’s sort of like the drunk who drops her keys and then only looks for them under where the streetlight is shining; it’s the easiest place to look, but that doesn’t mean the keys are there, and she’s likely going to miss them if the light is only shining on a small bit of street. We seem so focused on the ‘conventional wisdom’ (and so few of us have really read the studies) but that wisdom seems to have really not worked for so many people, so perhaps it’s time to focus more on what we haven’t yet tested.

pyrajane’s review #14: Buddha’s Brain: The Practical Neuroscience of Happiness, Love, and Wisdom by Rick Hanson with Richard Mendius, MD

BuddhasBrainMECH.inddWhen I’m not being judgmental, cold, cynical, sarcastic, fatalistic, angry, or hopeless, I try to be a better person.  Have a positive attitude, practice active kindness, find beauty and good in the world and all that crap.

Buddha’s Brain is an incredible resource.  It starts with the neuroscience of what happens in our bodies when we react to situations.  Without being textbook boring, Hanson looks at current (2009) advances in neuroscience and what science is continually learning about the brain.  It’s fascinating and helped me understand how biological reactions immediately become emotional responses.

You should read it.  I wrote a gigantic review over on my blog with my own practices and arguments with my brain.  If your brain seems to stay in panic mode or you have thoughts constantly stacking up and you just want to be calm for a moment and enjoy what’s happening, this book can really help.

HelloKatieO’s #CBR5 Review #8: The Purity Myth by Jessica Valenti

So, I was halfway through this book when Lollygagger posted this fabulous review on the CBR blog, which was then featured on Pajiba. I really don’t have that much to add. That review is a great summary of the book, it’s thesis, and why it’s important for both men and women to think about this topic. I’m going to address two things that jumped out at me.

First, how difficult is still can be for women to get access to contraception, abortion and needed healthcare.  Valenti’s stories about women being denied Plan B by pharmacists who have taken matters into their own hands, of women jailed after giving birth to still born babies, about proposals for miscarriage laws that require reporting a miscarriage so the state can determine if you endangered your unborn child, scared me. Valenti made the point that if a woman is considered mature enough by the state to carry a child to term and raise a child, the state should consider a woman mature enough to choose whether she wants to have that child at all (whether this be by accessing Plan B after a birth control lapse, or through abortion). The rhetoric most states use to limit access to birth control and abortion is that of the woman as a victim, as immature, as unable to make these decisions herself. I find that kind of rhetoric incredibly disturbing. Roe v. Wade was a huge victory, but things like Mississippi are still happening.

Second, the idea of women as gatekeepers is antiquated, and dangerous, for both men and women.
