One and a half years ago, in February 2009, I got a heart scan. It’s an X-ray measurement of how calcified your arteries are. Persons with high scores are much more likely to have a heart attack than persons with low scores. Scores in the hundreds are dangerous. Tim Russert, who died at age 58 of a heart attack, had a score of about 200 ten years before his death. Above age 40, the scores typically increase about 25% per year. That puts Russert’s score when he died at around 2000.

A few weeks ago I got another scan, at the same place with the same machine. Here are my scores. February 2009: 38 (about 50th percentile for my age). August 2010: 29 (between 25th & 50th percentile). In other words: 47% lower than expected. The earlier scan detected 3 “lesions”; the recent scan detected 2. The woman who runs the scanning center — HeartScan, in Walnut Creek, California — told me that decreases in this score are very rare. About 1 in 100, she said.

The only big lifestyle change I made between the two scans is to eat much more animal fat. After I found that pork fat improved my sleep, I started to eat a large serving of pork belly (with 80-100 g of fat) almost every day. Later I switched to 60 g of butter every day. The usual view, of course, is that to eat so much animal fat is v v bad and will “clog” my arteries. In fact, the reverse happened. Judging from this, the change was v v good.

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.

In downtown Berkeley I met a group of Chinese students from Beijing. They were entering freshmen at UC Berkeley.

They said there were 40 students like them — from Beijing, entering UC Berkeley. (At Tsinghua, there will be 400 entering freshmen from Beijing.) In all of China, 13 students were admitted to Harvard, about the same number to Yale and Princeton. One of them said she’d wanted to go to Northwestern but hadn’t gotten in. Had she gone to college in China, she might have gone to Renmin University, perhaps the #3 university in China.

Surely their parents were wealthy, yes. But they preferred an American college to a Chinese one for two main reasons: 1. They can choose whatever major they want. At Chinese universities students are often forced into a major they don’t want if their scores are high enough to get into a prestigious university but not high enough to get into the major they want at that university. 2. They believe that if they graduate from an American university they will have more opportunities. Where did they get the idea of coming to Berkeley? I asked. Online, they said. Their English was really good.

The “more opportunities” may not be as simple as they think. In Beijing I know a Chinese businesswoman who hired a recent college graduate. She’d gone to college in England, indicating that her parents were wealthy. The new worker turned out to be irresponsible and had to be fired. Perhaps her parents had spoiled her. In this businesswoman’s eyes, an overseas education may now be a negative.
