Food for thought - Eat your way to a better brain

When I see articles that attribute far-reaching health consequences to specific chemicals like anti-oxidants -- which are rarely tested in isolation from other compounds -- I'm reminded of a quote from Gary Taubes:

"If public health research functioned like some of the harder sciences -- high energy physics being the one I know best -- then researchers would be ridiculed and perhaps even run out of the field for over-interpreting their evidence or publicly presenting the results of sloppy experiments or basing claims on premature evidence and none of this would have happened."

Unfortunately, human research isn't as simple - you actually have to worry about the health consequences as well as the benefits. But correlations can be very meaningful. For instance, cross-cultural studies w/r to diets can be illuminating even as there are no experiments being run. Still, I'd place my bets, and my life, on fresh foods - high in anti-oxidants - over processed ones. The beauty is it ain't rocket science. And better, good diets can control and even inhibit pathologies (diabetes, heart disease, etc.).

I don't think the problem is one of complexity as such but more of being more complex than people imagine. Very few people have any knowledge of high energy physics, so only those who actually know what they're talking about offer an opinion, but everyone knows about food and diets, so everyone has an opinion.

On that note--does anyone know where to find basic information on nutrition that's not full of bullshit?

I took a nutrition class through an accredited correspondence school for a science credit. If you look around you should be able to find a school near you teaching the classes. Most of them suggest or require high school biology and chemistry and give you a nice background without marketing bs tossed in.

See a nutritionist. They'll go through your diet and help to plan healthier, and often tastier, alternatives. The best ones are like diet coaches.

Valid advice if you've got serious persistent problems with food, like overeating, junk food addictions, etc. But, if you already have a good diet and have no food-related health issues, then a nutritionist will likely be of limited utility--certainly less than a few hours of research on the Internet (careful research...citations needed).

Certainly there are some nutritionists who are on the cutting edge of the field and follow the latest research (and parse it with knowledge that most popular science coverage of food is bullshit), but I've come upon a few who mingled current trends with "ancient wisdom" a little too much and end up being purveyors of "alternative medicine". A friend of mine went on a huge soy kick for a year or two, because her nutritionist had bought into the "soy is a magical cancer preventative" hype. We now know with confidence that soy in many forms is actually kinda hard on the body (hormone producing chemicals in food are something that should be treated with caution, and not consumed in large quantities without careful study), and the research that indicated cancer prevention was probably overblown and certainly not specific enough.

So, see a nutritionist if you want, but take all advice with a grain of salt. Nobody knows everything, and moderation is probably the best choice when in doubt. (Though anyone who tells that you should eat more fruits and vegetables is almost certainly right. Moderation is probably not a concern with broccoli and carrots and blueberries.)

Quite honestly I've had my eyes opened. Good nutritionists aren't that hard to find and their expertise involves not just "persistent problems with food", but can also help you to avoid diets that cause health problems in the long-term. Even more amazing to me is that those health problems can be controlled through foods. The nutritionist can go through your family history and help you to understand your relationship with food and how it affects you - now and into the future.

"Though anyone who tells that you should eat more fruits and vegetables is almost certainly right."

That I can agree with. I should have also mentioned Michael Pollan's books. His most recent is an analysis of what to eat - and the subtitle says it all: Eat food^. Not too much. Mostly plants.

^whole, unprocessed.

The article appears to focus on the "Fernando Gómez-Pinilla, a fish-loving professor of neurosurgery and physiological science at the University of California" and a paper he has recently published.

I know this sounds terribly lazy, but the day when I'll simply get all these benefits from a pill tailored to my own bodies needs will be a sweet day indeed.

I use to agree until I started to enjoy cooking... (cheaper, healthier, and all that.)

Eating can bring a lot of joy to your life, preparing meals and enjoying with someone seems (imho) to contribute to a better, more well rounded lifestyle (equaling more productive hacking session.)

... food for thought (ducks).

The Omnivore's Dilemma is a must read. http://www.amazon.com/Omnivores-Dilemma-Natural-History-Meal...

They focus on fish a lot but they say nothing about the mercury content.

The only fish they mention is salmon. I'm not entirely sure all the health issues surrounding intensively farmed salmon have been established yet.

I would say mercury is only one aspect we should be concerned about.

Pfft, coffee and peanuts does me just fine.
