“…The historic rate of dietary changes during the development of human species far exceeded that of possible genotype alterations ( 2 ). Thus, our genotype is presumably not well adapted to the current abundance of refined grains and sugars, dairy products, and animal fats in the diets of industrialized populations ( 1 , 4 , 66 ). These considerations are used to explain the observations that a Mediterranean diet, which is rich in plant products and low in animal fats, is associated with lower risk of cardiovascular diseases ( 11 ).…”

The human gastrointestinal microbiota functions as an important mediator of diet for host metabolism. To evaluate how consumed diets influence the gut environment, we carried out simultaneous interrogations of distal gut microbiota and metabolites in samples from healthy children in Egypt and the United States. While Egyptian children consumed a Mediterranean diet rich in plant foods, U.S. children consumed a Western diet high in animal protein, fats, and highly processed carbohydrates. Consistent with the consumed diets, Egyptian gut samples were enriched in polysaccharide-degrading microbes and end products of polysaccharide fermentation, and U.S. gut samples were enriched in proteolytic microbes and end products of protein and fat metabolism. Thus, the intestinal microbiota might be selected on the basis of the diets that we consume, which can open opportunities to affect gut health through modulation of gut microbiota with dietary supplementations.

“…The human species underwent various changes during evolutionary history from the hunting and gathering period, the discovery of fire, to present times, mainly after the implementation of agriculture [2]. Humans are thought to have struggled to find food in sufficient amounts and quality to ensure survival for reproduction [3].…”

Diabetes mellitus is one of the most concerning non-communicable diseases worldwide. The prevalence of diabetes increased rapidly by the influence of socioeconomic interactions. The thrifty hypothesis postulates that certain genes that are involved in positive selection promote efficient fat deposition and storage. This is beneficial for the survival of mankind in adverse conditions. However, in this modern society, these genes have become disadvantageous as people are significantly less likely to experience famines and nutrition shortages. The socioeconomic development that has occurred during the 20th century induced abundance of food supplies in almost all regions of the world. This has led to a rapid rise in the prevalence of obesity, and type 2 diabetes as a consequence. Boom of diabetic pandemic in newly developed countries compare with others those who developed gradually can be explain by thrifty hypothesis, as a result of the difference in the exposure to environmental factors and famine by the ancestors leads. The globalization, urbanization, lack of physical activity, intake of high calorie food and migration is major cause of pandemic emergence of diabetes in high as well as middle and low-income countries.

“…Eaton and Konner (1997) stated that human genes had not changed since the Paleolithic period. Human beings are animals, submitted to the same environmental pressure as other animals and living species (Zucoloto, 2011). With this scientists have proposed several possible influences of diet in human evolution in which some can be highlighted: cranial-dental and bowel morphologic changes and increased energy needs leading to an elevated quotient between brain and body size (Mann, 2007).…”

a b s t r a c t a r t i c l e i n f oMeat has exerted a crucial role in human evolution and is an important component of a healthy and well balanced diet due to its nutritional richness. The present review attempts to sum up meats role and importance in human nutrition as well as examine some pejorative beliefs about meat consumption. Meat is a valuable source of high biological value protein, iron, vitamin B12 as well as other B complex vitamins, zinc, selenium and phosphorus. Fat content and fatty acid profile, a constant matter of concern when referring to meat consumption, is highly dependent on species, feeding system as well as the cut used. Pork meat can have the highest fat content but poultry skin is not far behind. It is also crucial to distinguish meat cuts from other meat products especially regarding its association with disease risk. As in other dietary components, moderation is advisable but meat has been shown to be an important component of a balanced diet.
