Dean Pomerleau Posted November 25, 2015 Report Share Posted November 25, 2015 On the thread about cranberries, Rodney got us talking about prunes, and how they may be good for maintaining bone health via increased IGF-1, which is a double-edged sword. This is pretty well-known among knowledgeable CR practitioners, but I thought it worth highlighting, particularly since I came across this interesting discussion & video on the potential tradeoff between "performance" and longevity with respect to IGF-1. It discusses (and gives citations) for many of the benefits of IGF-1, including muscle repair/preservation as well as long-term cognitive health. Interestingly, it doesn't mention helping maintain bone health as another benefit of the anabolic effects of IGF-1. But on the downside, it talks about increased cancer risk and the widely-observed reduced longevity (in humans and animals) associated with higher levels of IGF-1. Here is the summary paragraph: There you have it. It’s a trade-off when it comes to growth hormone and IGF-1. More of it enhances muscle and neuronal growth while simultaneously preventing atrophy. Less of it will increase the expression of stress resistance genes and extend your lifespan. Which do you prefer, having better muscle and cognitive performance or living longer? Overall, it seems like a good primer for anyone who wants to learn about the pros and cons of the reduced IGF-1 often associated with practicing CR. --Dean Link to comment Share on other sites More sharing options...
