Epigenetics does not mean that thinking makes it so : Respectful Insolence

".....The not-so-subtle implication is that the reason one gets sick is because of one's habits. Of course, there are a lot of lifestyle diseases, but the implications goes beyond the sensible, science-based observation that obesity and lack of exercise increase the risk of certain diseases, into the realm of stating that if you just eat the right foods and do the right exercises you'll never get sick.

Utter nonsense, of course.

There's also a dark side to this sort of thinking, and that's the flip side of the argument. If you can nearly completely control the state of your health by what you eat and do, the not-so-subtle implication is that if you get sick it must be your fault. After all, if we have complete control over our health through our lifestyle, then it follows that if you're sick, you must be doing something wrong....."

"The latest way that quacks are trying to push the idea that you have near total control over your health is by abusing new findings in epigenetics. Epigenetics is the study of heritable changes in gene expression or phenotype that are not caused by changes in the underlying gene sequence........ It's a fascinating area of research, because it suggests that gene expression can be altered longer than transiently by environmental influences. Of course, given that organisms and biology are affected by environmental influences, this is almost a trivial observation; the power of epigenetics is that it can explain how such changes in gene expression can come about.....
