Clearly, they lifted both food group pictures from some online culinary blog or magazine, because they are beyond clueless to the fact that the depicted meats are perfectly fresh free range chicken, line caught fish, high quality charcuterie (preserved meats, i.e. sausages, hams, etc.), prime beef, etc. I know what quality meats and poultry look like after 35 years working in the fine dining restaurant business.
In any case, it's unlikely Homo Sapiens would have evolved to be fully sentient if there were not plenty of omega 3 and 6 fats and complete protein in our ancestors' diets. Brains are high energy use organs. The bigger the brain, the higher the fat and protein intake needed to make 'em grow big enough to function properly. Oh, wait... Ha.
