Much debate and controversy exists between choosing GMO vs non-GMO food products. Unfortunately, the data and research are lacking behind the safety or dangers of GMO food products. So, until then we will wait for the long-term studies and effects of GMO consumption.
Many people do not know what GMO stands for, taken from the non-GMO project website (http://www.nongmoproject.org/learn-more/)

Is the extra money worth it???
Research studies say YES!
This is a great article based on numerous scientific studies that support the notion that Organic food is superior to its non-organic counterpart, both nutritionally speaking and in terms of toxicity.

Grow your own or visit local farms or farmer's markets. I like to visit Farmer's  markets towards the end and help them "clean out." They will often sell deeply discounted for bulk purchases. 

I thought this was a nice article providing tips on how to go Sugar-free: http://www.yogatraveltree.com/article/cure-sugar-addiction/   Thank you for your comments, Rob. If you haven't seen the movie, Fed Up, I suggest you do. Try the 10-day Sugar-free challenge (also, try to avoid the artificial sweeteners and high fructose corn syrup)...it's tough, sugar is EVERYWHERE!! If you slip, don't beat yourself up. Simply get back on the wagon and keep truckin'! Your mind and body will thank you.
