Chocolate, 100% unsweetened, is ~50% carbs. The xanthines are what give it a bitter taste (theobromine, caffeine and theophylline). The true (best) human diet is NOT about what 'tastes good'- actually most vegetables taste perfectly awful plain and virtually 100% of babies reject them on first exposure, while all accept meats (human milk and pulped meat are the only foods a newborn can digest- but be careful with the fat content). It is the complex of spices and cooking additives/techniques which make up 'cuisine' (I am a highly skilled cook).

Once habituated to the taste of vegetables, as I have noted, it is so difficult to move away from them that most people will never do it. The excuse is always those stated in the above posts by nancy lc et al. This is just their strong socialisation speaking loud and clear, it has nothing to do what is right, good or nutricious. At birth we have no 'taste' for anything, not even our mum's milk, just a sucking reflex. All food is acquired taste. The common question about 'isn't a diet of only meat boring?, is simply the result of the heavy spicing of most food items. Actually each feed of meat, even unspiced and when it is the exact same cut, smells and tastes heavenly and is consumed with gusto. Food does not have to be used as entertainment, but that is what it has come to be in our modern culture. Meals, especially in restuarants, are commonly treated as 'showtime'.

I dispute the claim about human coproliths in association with true plaeo- lithic remains- Those have been found only with meso- or neo- lithic sites. My research has not uncovered that claim for the true paleo- period. The claim of many modern 'research' projects are questionable, since financial sponsorship can and does predetermine outcomes.
