A new study in the Archives of General Psychiatry, summarized in the Wall Street Journal:

Researchers in the new study identified 81 people, ages 13 to 25, with warning signs of psychosis, including sleeping much more or less than usual, growing suspicious of others, believing someone is putting thoughts in their head or believing they have magical powers. Forty-one were randomly assigned to take four fish oil pills a day for three months. The other patients took dummy pills.

After a year of monitoring, 2 of the 41 patients in the fish oil group, or about 5%, had become psychotic, or completely out of touch with reality. In the placebo group, 11 of 40 became psychotic, about 28%.

The study is impressive not only because it uses ordinary food (fish oil) rather than  dangerous drugs (such as Prozac) but also because it studies prevention. Just as the ketogenic diet suggests a widespread animal-fat deficiency, so this study suggests a widespread omega-3 deficiency, which won’t surprise any reader of this blog. Completing the picture — I believe most Americans eat far too little animal fat, omega-3, and fermented food — baker’s yeast is being studied as a cure for cancer.

There isn’t even one fermented food on a list of “the 11 best foods you aren’t eating” compiled by Tara Parker-Pope, author of the world’s most visible health blog. Nor do any of the listed foods contain animal fat. One of them (sardines) is high in omega-3, so the list gets a D instead of an F. Fermented foods and animal fat (in sufficient quantity) have easily-noticed benefits, in contrast to every food on the list. Parker-Pope and the nutritionist she consulted (Jenny Bowden) have very large gaps in their understanding of nutrition.

Apparently. The obvious source is fish but we are running out of fish:

In 2006, aquaculture production was 51.7 million metric tons, and about 20 million metric tons of wild fish were harvested for the production of fishmeal. “It can take up to 5 pounds of wild fish to produce 1 pound of salmon, and we eat a lot of salmon,” said Naylor, the William Wrigley Senior Fellow at Stanford’s Woods Institute for the Environment and Freeman Spogli Institute for International Studies.

This is why Jared Diamond’s Collapse is so unfortunate. Diamond is a good writer and the question he tried to answer in that book is extremely important. But he whiffed. Suppose I write a book about obesity. I give a list of ten reasons people are fat: 1. Too much Food X. 2. Too much Food Y. And so on. (Just as Diamond gave a list of eight-odd reasons societies collapse.) Such a book would be far less helpful than a book with a correct theory about obesity, a theory that explains why Foods X, Y, etc. cause obesity. The theory could be used to find new, better, flexible ways of avoiding obesity. The list of foods to avoid cannot. In The Economy of Cities, Jane Jacobs (whom Diamond doesn’t mention) said that collapse happens for one overarching reason: The society is too resistant to new ways of doing things. The crucial struggle in any society, said Jacobs, isn’t between the rich and the poor or between owners and labor; it’s between those who benefit from the status quo and those who benefit from change.

Commenting on an earlier post, Jack Rusher reports:

Like Anonymous, I’m an MMA [Mixed Martial Arts] enthusiast. My experience with 3 T/day of flaxseed oil have been more or less identical to his. Before: high doses of NSAIDs [non-steroidal anti-inflammatory drugs] just to survive training, constant soreness and fatigue, etc. After: no joint pain at all, complete discontinuation of NSAIDs, lower frequency and severity of injury.
Dental results: my hygienist made strong comments regarding the improvement of my gums on my first post-flax visit, attributing it to changes in my oral care behavior . . . of which there were none.

I’m now 30 years old.  For the past ten years or so, I’ve had constant post-nasal drip and stuffed sinuses, frequently coughing out phlegm.  In addition, I’ve had fairly intense fatigue, moderate but consistent depression, and occasional but intense tendinitis (from typing). I tried nasal pharma sprays and many alternative therapies, feeling most intellectually compelled by neti pot style nasal washes with solutions that mimic salt balances of the body.  However, none of my efforts did much good.  So I reluctantly agreed to have sinus surgery, even though it seemed to be a blunt force approach to a sensitive tissue.  I have since become convinced that treating the sinuses as anything other than an expression of overall health is preposterous.  The surgery, with full anesthesia, improved things very slightly while being somewhat traumatic and certainly not worth the ordeal.

About 5 years ago, when I was 25, I discovered that I have a very under-active thyroid. Taking thyroid replacement was  the biggest health change I’ve had in the past ten years, giving me much more energy, improving my overall health, and significantly reducing (but not eliminating) my sinus condition.

I didn’t start reading your blog regularly until a few months ago.  Your writing on bacteria and flax oils led me to start taking probiotic pills every day (Trader Joes brand and then kyodophilus), eat more yogurt and kimchee, and take flax seed oil pills and try to incorporate flax oil into foods.  Within a month of starting this, my sinus congestion was reduced by about 90%.  I don’t need to constantly have tissues on hand and I can breathe easier every day. Thank you! I’m hoping to finally start making my own kombucha this week.

I suspect it was the bacteria rather than the flaxseed oil that helped his nose. Like him, I used to need to carry a handkerchief at all times and I went through a whole box of Kleenex in a few months. This didn’t stop when I started drinking lots of flaxseed oil. After I started drinking lots of fermented foods, however, my nose became a lot clearer and my Kleenex consumption went way down.
