In a long comment on an earlier post, JohnG tells how he failed and succeeded to get rid of disabling exercise-induced asthma. Lots of things didn’t work:

I tried Vitamin D; it didn’t work, but it did help my nasal allergies somewhat. I tried low carb dieting, and just like Dr. Lutz of “Life Without Bread” said, it made asthma worse while it practically cured my nasal allergies. I also tried the Dr. Sears approach of taking as much as 7.5g of EPA/DHA a day; no change at all in the exercise induced asthma.

The idea that asthma is due to lack of microbes made sense to him and he started trying fermented foods and probiotics. At first, nothing:

I re-reviewed the probiotic slant and found the Helminth story and all the trials that were going on in PubMed for them. With that logic in hand, I set about to find a probiotic that worked. I tried yogurt, kefir, fermented cabbage, and buttermilk to no avail. I then tried store bought probiotics one by one. I tried The Maker’s Diet probiotic and it didn’t help; but I do think it helped make a 20 year long wart go away. I also tried all forms of probiotics on the market; even LGG. Nothing.

Finally, success:

I bought this super high dose probiotic and took it along with a L. Sporogenes/bacillus coagulans. Voila, three days later I could really feel the difference during exercise. I continued that for 10 days. By the 10th day, I didn’t have to hit my inhaler at all during exercise. Wow!

First, I had to decide which probiotic did the trick. I didn’t want to spend a ton on that high dose probiotic, so I stuck with the Bacillus Coagulans and it continued working normally. So, I found my probiotic. Now, I needed to verify it wasn’t placebo. A close cousin to exercise induced asthma is the phenomenon of waking up sneezing and then promptly getting an asthma attack/or closure after that.

I went off my bacillus coagulans that I had been on for 14 days. By the second day, I noticed a little difference. By the third day, I had to hit my inhaler during the workout. By the 10th day (bacillus coagulans supposedly lives in your intestines 7 days), I was full-blown back to having to use 4 inhaler puffs and it wasn’t doing the trick. This was test phase one.

I then went back on the bacillus coagulans for 10 days. The same process repeated itself. The nightly asthma attacks abated after about 4 days and the same no-puff needed during exercise continued as well.

I then went back off the bacillus coagulans for 10 days. I got the asthma back at day 3.

I’ve now been back on 5 billion CFU’s of bacillus coagulans (duraflora) for 18 days. I don’t have to use my inhaler for exercise. I can feel the asthma come on very slightly and then go away.

Very impressive. Shows what can happen if (a) you think for yourself, (b) persist, and (c) have access to a lot of helpful information. I think he needed all three.

This recent study from Japan found that middle-aged men and women who ate more saturated fat had a lower risk of stroke. The rate of strokes was 30% lower in the highest intake quintile compared to the lowest quintile. There was a non-significant reduction in heart disease.

Other big differences were correlated with saturated fat intake. For example, those in the highest quintile had more college education than those in the lowest quintile and were more likely to do sports >1 hr/week. These data by themselves won’t convince anyone that saturated fats are beneficial. But they should push you in that direction. Contrary to what you’ve heard a million times.

As far as I can tell, eating lots of butter has lowered my blood pressure. High blood pressure is associated with greater risk of stroke.

Although pig fat certainly helped me (I slept better), I’ve found butter is even better. Butter has considerably more saturated fat than pig fat.  The fat in butter is  60% saturated fat, whereas pig fat is 40% saturated fat. My consumption of 60 g/day of butter gives me 36 g/day saturated fat. In this study, persons in the highest quintile of intake averaged 20 g/day. The highest intake in the whole study (60,000 people) was 40 g/day. In addition to butter, I eat cheese, whole-fat yogurt, and meat, so I’m surely higher than that.

Open-access is why you’re reading this. Because my long self-experimentation paper was in an open-access journal, many people could easily read it. I’m sure this is why I managed to get a contract to write The Shangri-La Diet.

The BMJ is experimenting with a way to support open access: Ask for publication fees from authors with grants that include the appropriate support.

We are introducing this policy as the next step in our efforts to ensure the sustainability of open access publication of research in the BMJ, and we are doing so in the spirit of experimentation. Many research funding organisations, sponsors, and universities now provide grants that cover journals’ fees for open access publication.

Wise. While I was writing The Shangri-La Diet, I visited Alice Water’s Edible Schoolyard. I learned that it cost hundreds of thousands of dollars a year, provided by foundations. As far as I could tell, the people in charge were doing nothing to reduce the subsidy required. Yet they wanted the idea to spread.

It would have been harsh to title this post “Marc Hauser, RIP”. However, unless  the following is shown to be in error, I’ll never believe anything he writes or has written:

According to the document that was provided to The Chronicle, the experiment in question was coded by Mr. Hauser and a research assistant in his laboratory. A second research assistant was asked by Mr. Hauser to analyze the results. When the second research assistant analyzed the first research assistant’s codes, he found that the monkeys didn’t seem to notice the change in pattern. In fact, they looked at the speaker more often when the pattern was the same. In other words, the experiment was a bust.

But Mr. Hauser’s coding showed something else entirely: He found that the monkeys did notice the change in pattern—and, according to his numbers, the results were statistically significant. If his coding was right, the experiment was a big success.

The second research assistant was bothered by the discrepancy. How could two researchers watching the same videotapes arrive at such different conclusions? He suggested to Mr. Hauser that a third researcher should code the results. In an e-mail message to Mr. Hauser, a copy of which was provided to The Chronicle, the research assistant who analyzed the numbers explained his concern. “I don’t feel comfortable analyzing results/publishing data with that kind of skew until we can verify that with a third coder,” he wrote.

A graduate student agreed with the research assistant and joined him in pressing Mr. Hauser to allow the results to be checked, the document given to The Chronicle indicates. But Mr. Hauser resisted, repeatedly arguing against having a third researcher code the videotapes and writing that they should simply go with the data as he had already coded it. After several back-and-forths, it became plain that the professor was annoyed.

“i am getting a bit pissed here,” Mr. Hauser wrote in an e-mail to one research assistant. “there were no inconsistencies! let me repeat what happened. i coded everything. then [a research assistant] coded all the trials highlighted in yellow. we only had one trial that didn’t agree. i then mistakenly told [another research assistant] to look at column B when he should have looked at column D. … we need to resolve this because i am not sure why we are going in circles.”

The research assistant who analyzed the data and the graduate student decided to review the tapes themselves, without Mr. Hauser’s permission, the document says. They each coded the results independently. Their findings concurred with the conclusion that the experiment had failed: The monkeys didn’t appear to react to the change in patterns.

They then reviewed Mr. Hauser’s coding and, according to the research assistant’s statement, discovered that what he had written down bore little relation to what they had actually observed on the videotapes. He would, for instance, mark that a monkey had turned its head when the monkey didn’t so much as flinch. It wasn’t simply a case of differing interpretations, they believed: His data were just completely wrong.

As word of the problem with the experiment spread, several other lab members revealed they had had similar run-ins with Mr. Hauser, the former research assistant says. This wasn’t the first time something like this had happened. There was, several researchers in the lab believed, a pattern in which Mr. Hauser reported false data and then insisted that it be used.

If taken literally, this description seems to imply that Hauser was making up data — writing down results much more favorable to his career than the actual results — and not realizing it! As if someone else was marking the data sheet. Since the videotapes are being coded by more than one person the fabrication/delusion/whatever would come to light, you might think, but he does it anyway! And then gets “a bit pissed” when things don’t work out perfectly.

I would love to hear Hauser’s side of this story, and see the videotapes being coded. So far Hauser has said nothing to make me doubt the straightforward interpretation: He made up data. After Saul Sternberg and I published a paper implying that Ranjit Chandra had made up data, Chandra retired.

Derek Bickerton says Hauser “fell victim to a soon-to-be-outdated view of evolution”. I am more interested in what this says about Harvard and Hauser’s co-authors. In particular, I wonder what Noam Chomsky, one of Hauser’s co-authors, will say. The incident makes Chomsky look bad. Hauser appears to be a person who pushes aside the truth of things. That Chomsky wrote a major paper with him suggests that Chomsky failed to notice this.
