My mistake in assuming everyone wants striations in their ass. Wait, wut??? Seriously? J/K
And to answer your question "why eat nutrient void foods"? YES....because it tastes good! There is nothing wrong with enjoying your food. And eating crap in moderation will not harm you in any significant way assuming most of your diet is based in solid, whole foods rich in micro-nutrients and phyto-nutrients. So eat yer cake, ok?
