« on: February 24, 2013, 05:57:09 pm »
All of the food this week was organic and it was all consumed whole (no juicing, no blending, as usual):
2/18 – 1 pineapple, zucchini, dates.
2/19 – 1 pineapple, zucchini, dates.
2/20 – zucchini, dates.
2/21 – tomatoes, zucchini, dates.
2/22 – tomatoes, zucchini, dates.
2/23 – tomatoes, zucchini, dates.
2/24 – tomatoes, zucchini, dates.
My wife had an ultrasound this week, the first she’s had during this pregnancy. It looks like there’s a healthy baby boy in there! My wife’s official due date is July 12, but based on the ultrasound, the baby is a little farther along than that…the ultrasound predicted a birth on July 2 (I think my wife’s tendency to ovulate early explains the discrepancy). Rose was quite cute during the scan ("why is she wearing gloves?", etc.). It was reassuring to see that the heart, other organs, etc. have developed normally. My wife got this done at around 20 weeks…about halfway through the pregnancy. At this point, the basic body structure is there, and baby just needs to spend the next several months gaining weight. Based on the measurements of the head size, femur length, etc. made during the scan, they calculated his current weight to be 15 ounces (just under a pound). Unless something out of the ordinary occurs, I don’t think they’ll be a need to do any additional ultrasounds during this pregnancy.
I really think that two kids, a girl & a boy, 4 years apart, is perfect…I guess what I’m really saying is that I don’t think we’ll plan on having additional children. If we had two boys or two girls, the thought of a third child would sound a bit more tempting. With two kids, we can still drive a normal-sized car. If we had three, a minivan might be necessary.

At a check-up with the midwife in late January, she drew some blood from my wife to check for a number of things, including her levels of vitamins D & B12. When I mentioned to the midwife that I’m a vegan who doesn’t take a vitamin D supplement, and who tries to get a fair amount of sun, she expressed an interest in testing my vitamin D level too, because she was wondering how high a person’s can be in southern California in the winter who doesn’t supplement.
This week we got our test results back. My wife’s vitamin D level tested at 20 ng/mL, whereas my level was 25 ng/mL. Prior to that, my wife was taking a prenatal multivitamin daily containing 400 IU of vitamin D and also getting a little sun, while I was not supplementing at all and getting more sun than my wife. Rose gets about the same amount of sun as I do, so her vitamin D level is probably around mine.
After getting these results yesterday, I told the midwife I’d look into it a bit more, and today I sent her this message:
“Check out this 2 minute youtube video made by MD Michael Greger summarizing some recent vitamin D research, including the “U shaped mortality curve” I mentioned to you yesterday: http://www.youtube.com/watch?v=etzh51dLy1Y.
In regards to how long it takes for vitamin D levels to rise after supplementation, a number of websites say that it takes 4 or 5 weeks (see, for example, http://www.livestrong.com/article/532981-how-long-does-it-take-to-feel-the-effects-of-vitamin-d-supplements/). Thus, I am inclined to think that my result of 25 ng/mL in late January is acceptable, because this is probably the lowest my vitamin D levels get the entire year.
On the other hand, I do think that my wife’s result of 20 ng/mL is a bit too low. Prior to that test, she had only been getting 400 IU a day in her multivitamin, along with a very small amount of sun. But then we picked up a vitamin D supplement at the beginning of February, and since then she’s been taking 2500 IU a day. According to Dr. Greger, this is probably about right in order to get her levels up to somewhere around 30 ng/mL (http://www.youtube.com/watch?v=ADFvhM6tcf0).
And regarding B12, at home on our bookshelf, we’ve got the book “Could it be B12?” (http://www.amazon.com/Could-It-Be-B12-Misdiagnoses/dp/1884995691/ref=sr_1_1?ie=UTF8&qid=1361711245&sr=8-1&keywords=could+it+be+b12). According to this book, the most accurate B12 test is the urinary MMA/creatine ratio test (available at http://www.b12.com/). And Dr. Greger agrees that the MMA B12 test is a better test than serum B12 (http://www.youtube.com/watch?v=48IYo8XSGQM). You mentioned to me yesterday the MCV test for B12. It is true that B12 deficiency can cause an abnormal MCV test result, but many other things can too (http://www.medfriendly.com/meancorpuscularvolume.html), so this by itself is not sufficient to diagnose a B12 deficiency.”

In my last post, I commented that recently I’ve noticed a “gradual increase in my strength”. Well, since I started eating lots of zucchini about five months ago, I’ve also noticed a gradual increase in my weight. In fact, I’ve gone from about 150 lb to about 168 lb in that time span (weighing myself naked when I wake up in the mornings). During this time, my activity has consisted primarily of body weight exercises done in our home. I’ve run very little in recent months (I tend to run more in the summer than in the winter, unless I’m training for something).
So I’m going to give my thoughts on this observation, but first, let me back up. I’m about 5’ 9’’. For my height, I’ve got a pretty solid skeletal frame. My shoulders are broader, and my arms are longer, than most people my height. A way to quantify this is with the “ape index”, which is a measure of a person’s arm span relative to their height (http://en.wikipedia.org/wiki/Ape_index). Take your arm span and subtract your height (in inches). For an average person, the answer is zero (according to Leonardo da Vinci, and other people). I've got an armspan of 73 inches, but am only 5 feet, 9 inches tall (i.e. 69 inches), and so have an ape index of +4 inches. This is certainly above average. Hence, I will naturally tend to be a bit heavier than most people my height.
And, I love to eat. Prior to switching to a raw vegan diet, I was always mindful of eating too much and gaining excessive weight. I was always athletic and health-conscious, and I always felt that I had to exercise a lot, and eat less than what I wanted, in order to avoid becoming chubby (this is no longer the case on a raw vegan diet). Over the past dozen years, I’ve also experimented with the frequency of my meals. I’ve tried one meal a day up to five meals a day, and the past couple years I’ve stuck with eating twice a day.
From about age 16 in high school, through all of undergrad, and during my first few years of grad school, I usually weighed in the 170s. At the time, I jogged a bit, but my primary athletic interest was in weight lifting. I was a pretty muscular ~175 lb. I always had access to a gym during those years, and pumped iron on a regular basis. But then, in 2005-2008, I had a shift in my interests. I gradually lifted less and less, and ran more and more. I started racing marathons and ultramarathons, and dropped weight. I found that I ran my best when I weighed in the 140s. Part of the initial reason why I adopted a raw vegan diet was because I found that it was easier for me to maintain this lighter weight when I ate this way.
In my adolescent and adult life (spanning the past 20 years…I’m 34 now), my weight has ranged from about 120 lb to about 180 lb. I got down to 120 lb, as an experiment, in 2009. I didn’t fast, I just consistently under ate (and thus, felt hungry most of the time when doing this). The real reason why I did it was because I was curious. I knew that I ran better when I weighed in the 140s than I did when I weighed in the 170s. Would it follow then that I’d run better when I weighed in the 120s than I did when I weighed in the 140s? After all, African marathon runners are really thin. I got down to 120 lb to test this hypothesis, and my wife said that I looked “scary” at the time. The conclusion I drew from this experiment was that I ran better when I weighed in the 140s. When I weighed in the 120s, I felt too weak to run well. Apparently, some professional runners my height run their best when they are in the 120s. But, not me.
After I learned in 2009 that I don’t run well when I weigh in the 120s, I started eating more raw vegan foods, and gradually gained weight. At the time of the fruit festival in 2012, I weighted about 150 lb. And at that time, I thought that was as heavy as I could get while eating a fruitarian diet, because I was eating as much as I wanted, and my weight had been pretty stable in the year prior to that. So, initially I was surprised by my weight gain over the past several months when I started eating more zucchini. However, in retrospect, it isn’t too surprising. By eating more zucchini, I have significantly increased my protein intake. A common symptom of a low protein diet is “weight loss”, and so thus it isn’t too surprising that I gained weight when I started eating more protein. Despite the fact that I seem to have gained about 18 pounds in the last 5 months, I do not appear to have had an increase in body fat. In fact, I think that my body fat percentage in recent months has gone down a bit.
My wife, it’s worth mentioning, likes it when I’m heavier and stronger. Given this, and the fact that I have no intention of running a marathon in the near future, I’m inclined to think of this recent weight gain of mine as being a good thing.
--------------
I also mentioned in my last post about how I enjoy eating simply. A second, scientific, advantage of eating this way is that just eating a few different foods makes it easier for me to deduce with confidence what effects the different foods have on my body. Over the past few years, I may have been able to come to conclusions that other raw vegans cannot, simply because there are fewer variables in my diet which might be responsible for the effects that I observe.
