Neanderthals had a sweet tooth and enjoyed cereals and other carbs, suggests a new study that analyzed food remains that were stuck on and between their teeth.

This, of course is no reason to abandon our low carb, no-bad-carbs eating habits, but it does make me think that, on occasion, some grains are ok. It boils down to quantities consumed, levels of physical activity, etc.
