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 ...
In the 21st century, the sequencing of the human genome and DNA analysis of the remains of early humans have found evidence that humans evolved rapidly in response to changing diet. This evidence undermines a core premise of the paleolithic diet – that human digestion has remained essentially unchanged over time. [5]
The first commercial production of dried milk was organized by the Russian chemist M. Dirchoff in 1832. In 1855, T.S. Grimwade took a patent on a dried milk procedure, though a William Newton had patented a vacuum drying process as early as 1837.

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 ]
The evidence of early Homo sapiens diet stems from multiple lines of evidence, and there is a relative abundance of information due to both a larger relative population footprint and more recent evidence. A key contribution to early human diet likely was the introduction of fire to hominins toolkit.
The first recommended dietary allowances for humans were developed to address fears of disease caused by food deficiencies during the Great Depression and the Second World War. [3] Due to its importance in human health, the study of nutrition has heavily emphasized human nutrition and agriculture, while ecology is a secondary concern. [4]
The population of early humans dwindled to around 1,280 individuals during a time of dramatic climate change and remained that small for about 117,000 years, the study said.
The Neolithic Revolution greatly narrowed the diversity of foods available, resulting in a decrease in the quality of human nutrition compared with that obtained previously from foraging, [5] [6] [7] but because food production became more efficient, it released humans to invest their efforts in other activities and was thus "ultimately ...
