Lifextension argues that very case in a recent blog post. If the paleo diet is low carb, then it’s going to be heavily animal-based. According to Lifextension:
Diachronic and comparative analysis of the skeletal data of human hunters and cultivators from across the globe has revealed that – prior to the onset of agriculture – carbohydrates must have comprised only a rare and occasional component of ancestral eating patterns. Furthermore, the impact of the introduction of carbohydrates to human diets was almost immediate in its deterioration of human health and biology.
However, paradoxically, many proponents of a ‘Paleo’ (i.e.: pre-agricultural) diet have promoted the use of tubers and other starches as – not only benign – but necessary health foods to consume for the correction of metabolic and endocrine disorders. Potatoes, rice, and other oxymoronically-labelled ‘safe’ starches, are being promoted in spite of the fact that they are exclusively Neolithic foods. Consequently, it is the conflation of starches, safe, and ancestral that I now wish to address, and hopefully correct.
The intake of plant foods by hominids was most plausibly and conceivably minimal. This is due to their limited, seasonal availability; the physiological ceiling on fibre and toxin intake; the biological evolution of early Homo physiology; along with the technological, spatial and temporal limitations of obligatory pre-consumption preparations. Consequently, evolutionary arguments for the consumption of what are quite blatantly Neolithic foods are rendered paradoxical and absurd. Starches are neither ‘Paleo’; nor does our evolutionary biology sanction them as ‘safe’.
Lifextension neither pulls punches nor takes prisoners. This could get interesting.
