I just think if you are going to induce hormesis, it's best done with "natural" "toxins" rather than MSG, trans-fats, food coloring, artificial flavors and whatever other additives. That's my only critique. Otherwise, I do agree that if you have a cookie or a plate of pasta once in a while there's no reason to panic. If I ever hike the Pacific Crest Trail again I will likely consume large quantities of oats and corn (in the form of Fritos, as well as potatoes in the form of chips and fries) to make the distance, so it's not like I'm a total hardliner when it comes to this stuff.
