Peter S. Unlike tropical Africa, meat could be stored during the freezing winters of the far north to provide a reliable food source, especially in the form of large carcasses of elephant-like proboscideans. So did early humans prefer to temper their meat-eating with a certain amount of veg, and if so, how much? Your friend’s email. Nate left before dawn on this day in January with his rifle and machete to get an early start on the two-hour trek to the old-growth forest. Eating red and processed meat—what do scientists say Mar 06, Our bodies did not evolve to be in harmony with a past diet.
Much attention is being given to what people ate in the distant past as a guide to what we should eat today. Advocates of the claimed palaeodiet recommend that we should avoid carbohydrates and load our plates with red meat and fat. Its critics, on the other hand, argue that these are the same ingredients that would set us up for heart attacks. Moreover, these animal-derived foods require more space to produce on our crowded planet filled with starving humans. A factual foundation for the debate is provided by a review of the eating patterns of early humans and how we adapted to digest starches softened by cooking. The researchers contend that it was digestible starches that provided extra energy needed to fuel the energy needs of bigger brains, rather than extra protein from meat to grow these brains. But the most striking thing about human diets is just how variable they have been and the adaptations that have taken place. Furthermore, the American evolutionary biologist Marlene Zuk in her book Paleofantasy contends that these dietary adaptations are not fixed on what our ancestors ate in caves at some time in the past. So are our energy, or protein, needs much different from other mammals of similar size? Brains demand a lot of energy but so does the liver and the digestive tract. The extra nutrition that we need for brain work may be counterbalanced, at least partially, by a lesser need for.
