In my family, height and dietary PUFA consumption appear to be very well correlated, and the age of puberty seems to support this as well. It's so obvious to me at this point that it's rather boring. I guess I could get "excited" again if there were some good experiments being conducted, but at this point we can only rely on the evidence that now exists. In England there was a lot of refined sugar consumption in the 1800s, and I agree that it is not opitmal, but it now usually goes hand in hand with a PUFA-rich diet and also a diet deficient in at least some vitamins and minerals, so one would have to control for many factors.
As to "moving the goalposts," I don't agree, and the reason is that in biology and biochemistry, what matters are thresholds - there are few if any absolutes. Almost all the time, a large man will need to drink a lot more alcohol to become intoxicated as compared to a small woman, for example. I don't think there is any physiologically or biochemically relevant amounts of AA anywhere in my body at this point, if there is any at all. One molecule of AA therre might be somewhere. I'm more than willing to discuss a possible experiments about this, with the "loser" to pay for all expenses. |
