Seth’s blog

In an interview, Bruce Springsteen said:

I wasn’t quite suited for the educational system. One problem with the way the educational system is set up is that it only recognizes a certain type of intelligence, and it’s incredibly restrictive — very, very restrictive. There’s so many types of intelligence, and people who would be at their best outside of that structure [get lost].

Yes! That’s what I’m saying here, here, and here. The quote is from David Shenk’s great new blog about talent and how to nurture it.

In The Death and Life of Great American Cities, Jane Jacobs wrote, “Old ideas can use new buildings, but new ideas need old buildings.” New ideas need old buildings because old buildings are cheap. New ideas cannot be expected to be especially profitable, or profitable at all, at first. This is why self-experimentation should have a permanent place in the ecology of science: It provides a cheap way to develop new ideas.

Self-experimentation is for everyone just as blogging is for everyone. You don’t need fancy equipment to be an interesting blogger and you don’t need fancy equipment to do interesting self-experimentation — at least I think my recent omega-3 results are interesting. Here are the easy-to-find materials I used:

1. To measure my balance, I used a bamboo cutting board ($15), a 0.5-inch pipe plug ($1), a booklet with about 20 pages (free), and a stopwatch ($10). Here they are:

This shows the size of the pipe plug:

I put the booklet on the floor and put the pipe plug in a cut-out hole in its center. The hole goes about halfway into the booklet (e.g., 10 pages out of 20).

Then I balance the cutting board on top of the pipe plug:

I stand on my right foot on the cutting board; the measure is how long I can balance on it before my left foot touches the floor.

2. To vary the amount of omega-3 in my brain, I used these oils:

Walnut oil and flaxseed oil are high in omega-3 fats; sesame oil is low.

If you are interested in doing similar experiments, feel free to contact me.

The omega-3 story began with the circulatory system. In the 1960s, two Danish scientists wondered why Eskimos rarely die of heart disease. Could the answer explain the sharp decrease in heart disease mortality in Norway during World War II? In spite of this promising beginning, the heart and mortality benefits are still not clear. A 2006 meta-analysis of heart disease studies concluded that “omega 3 fats do not have a clear effect on total mortality, combined cardiovascular events, or cancer.”

You can find lots of recommendations to consume omega-3 fats in various forms — fish, supplement, and so on. On the other side, Marion Nestle, the author of What To Eat, seems to believe the advantages claimed for omega-3 are “hype.” Most researchers are less certain. From a recent New York Times article about Martek, a company that makes an omega-3 food supplement:

“A lot of the claims made for DHA [a form of omega-3] are in the realm of hypotheses,” said David Schardt, senior nutritionist at the Center for Science in the Public Interest, an advocacy organization based in Washington. “They are certainly worth pursuing, but there’s not yet enough proof to warrant telling people to go out of their way to take DHA.”

The exceptions, Mr. Schardt said, are people with a history of heart disease and premature infants, who need an extra boost of DHA for proper brain and eye development to compensate for their early exit from the womb.

Martek’s scientists, when pressed, generally agreed with Mr. Schardt. The data showing any health benefits of DHA beyond those related to the heart or premature infants, while encouraging, is not quite conclusive, they say.

The typical experimental study of omega-3 takes two groups of people with a pre-existing problem, gives one group omega-3 and the other group a placebo, and measures outcomes several months later. A 2005 study in Pediatrics, for example, compared two groups of children (n = about 60/group) with Developmental Coordination Disorder. Most of them had ADHD. One group was given an omega-3 supplement; the other group was given a placebo. The children were tested before treatment and after three months of treatment. (The reading, spelling, and behavior scores of children in the supplement group improved more than the scores of children in the placebo group.) Studies like this are hard.

In summary, there is considerable uncertainty about the effects of omega-3; and the methods used to reduce that uncertainty are slow and difficult. This is why self-experimentation might help.

My recent data. The Queen of Fats (2006) by Susan Allport, a science writer, is an excellent introduction to the subject.

Today I attended a two-hour class associated with the San Francisco Fancy Food Show called “Tradition + Technique + Terroir = Taste of European Traditional Foods.” The class covered four hams, five cheeses, three olives, and two beers. The general idea was to explain how great these foods are so that the students — mostly food retailers — can successfully sell them. One of the cheeses was a cheddar. There is a town in England called Cheddar, I learned.

I asked a question: “When an American cheese maker makes a cheese and calls it a cheddar, what are they doing?”

“It doesn’t taste the same!” said the American retailer who was in charge.

This irritated me. “When an American cheese maker makes a cheese and calls it a cheddar, it isn’t a joke,” I said. “There’s a reason for it.” Then the process called cheddaring was explained.

The people who make English cheddar cheese (the original), the people who make Greek feta cheese (the original feta), and many other food producers would like no one else to be able to use the names cheddar, feta, etc. Inside the European Union, that is often the case: Only Greek feta can be called feta, for example. A new EU program labels foods with “Protected designation of origin” or “Traditional specialty guaranteed” as a way to help consumers know that they are getting the traditional original product.

This is a half-measure. I am in favor of anything that helps preserve the diversity of what we eat, so I am in favor of this program. I am in favor of telling the stories behind English cheddar, Greek feta, and so on. But this sort of thing is a half-measure because the best way to ensure the survival of a food is to ensure it tastes better than similar foods. A labeling program does not do that. Not in the slightest. Perhaps future efforts should be focussed on how to make customers more discriminating. Here is the truth: Traditional products often taste very good. Here is the half-truth: They taste very good because they are traditional. Here is the (implicit) lie: Non-traditional products taste worse because they are non-traditional.
