The diet of known human ancestors varies dramatically over time. Strictly speaking, according to evolutionary anthropologists and archaeologists, there is not a single hominin Paleolithic diet. The Paleolithic covers roughly 2.8 million years, concurrent with the Pleistocene, and includes multiple human ancestors with their own evolutionary and ...
The stated rationale for the paleolithic diet is that human genes of modern times are unchanged from those of 10,000 years ago, and that the diet of that time is therefore the best fit with humans today. [45] Loren Cordain has described the paleo diet as "the one and only diet that ideally fits our genetic makeup".
Early human nutrition was largely determined by the availability and palatability (tastiness) of foods. [2] Humans evolved as omnivorous hunter-gatherers, though our diet has varied significantly depending on location and climate. Historically, the diet in the tropics tended to depend more heavily on plant foods, while diet at higher latitudes ...
Nutritional science is the study of nutrition, though it typically emphasizes human nutrition. The type of organism determines what nutrients it needs and how it obtains them. Organisms obtain nutrients by consuming organic matter, consuming inorganic matter, absorbing light, or some combination of these.
Nutritional science. Nutritional science (also nutrition science, sometimes short nutrition, dated trophology[1]) is the science that studies the physiological process of nutrition (primarily human nutrition), interpreting the nutrients and other substances in food in relation to maintenance, growth, reproduction, health and disease of an organism.
Human nutrition deals with the provision of essential nutrients in food that are necessary to support human life and good health. [1] Poor nutrition is a chronic problem often linked to poverty, food security , or a poor understanding of nutritional requirements. [ 2 ]
