Nature vs. Nurture...Nurture is winning

Yesterday's WOD Results:  Pullup Insanity.

I don't agree with everything in this article but it's worth reading.  Here's an excerpt:  Similarly, while your genes are “fixed”, the expression of those genes – the amount of proteins they cause to be made, whether or not they are even switched on or off at all – depends on the “environment,” the circumstances surrounding those genes. Diet, exercise, exposure to toxic chemicals (or fresh air), medicines, even the thoughts you think (which generate actual chemical signals) all influence gene expression – positively and/or negatively, depending on the choice. Eat a diet that is high in sugar, and gene expression moves in a direction that produces more insulin, that shuts off insulin receptors, that down-regulates lipase and other enzymes involved in fat-burning, that increases pro-inflammatory cytokines, etc. When you change to a diet low in sugars and rich in healthy fats, those or other genes are directed to reduce inflammatory expression, down-regulate insulin-producing metabolic machinery, up-regulate insulin receptors and rebuild cell membranes to reflect the presence of better building materials (omega 3 fatty acids, etc.). 

We don't have to eat and exercise like our parents did or our friends do.  Heart disease may run in my family but if I have a healthy lifestyle those genes may never be expressed.  The same is true for diabetes, many types of cancer, and obesity.  It's a pretty simple formula:  Eat meat, vegetables, nuts, seeds, & fruit, lift heavy objects regularly and do some intensity exercise.  Don't spend more time with your couch than you do with your kids.  Crossfit!

This is probably the last pic you'll see with blue & yellow walls.  BJ locks it out.
