that energy boost you're referring to, you can get easily from the complex carbs in the 'healthy' food you eat, only this one comes without the nasty side effects. the energy from complex carbs just lasts longer--a good thing, and doesn't spike suddenly--also a good thing, so the difference isn't as easily perceived by the individual experiencing it. but then there's no crash... or side effects, cause the energy is easily maintained over long periods of time.
i just described a natural diet for human beings. consider the following:
sugar, as in the great white death, wasn't part of the human diet, globally, until when exactly?
Answer: Indians discovered how to crystallize sugar during the Gupta dynasty, around AD 350. And sugar wasn't produced in any decent quantity until the 1390s when the development of a better sugar cane press doubled the juice obtained from the cane during production (wikipedia).
the agricultural revolution took place around 13,000 years ago. we only started eating sugar on a regular basis around 600 years ago as a species, and our intake levels have skyrocketed in the last hundred year. so, people have been around forever in comparison to how long we've been eating sugar, especially at the levels we do today in the US of A.
do you really think behavior like this isn't going to have a severe effect on our health and abilities? the question is really whether or not it's a good effect or not. and from my experiences, i've concluded that it's not good at all, far from it.
you're argument that one should eat it anyway cause it's there anyway, is as good as saying one should wrap their lips around the tailpipe of their car and inhale, cause that crap is in your air anyway.
and i suppose my kids should do drugs occasionally too, cause the statistics suggest that at some point they'll be exposed to them anyway... and rugs can be fun, relaxing, or energizing.
no wait, we should all just pop vitamin and caffeine pills and work ourselves to death cause we can be far more productive when juiced up, and why eat real food when it takes longer than just popping a pill.
i used a lot of words, but all i just said was. you're stupid!!!
