These examples illustrate the importance and interaction of extrinsic and intrinsic factors in modulating and integrating nutrient metabolism, and in determining the nutritional status of the organism.
Food also provides materials from which all the structural and catalytic components of the living cell can be assembled. The prevailing global increase in the development of acquired metabolic syndromes is associated with nutrition transition [29,30]. Siscovick DS, Barringer TA, Fretts AM, Wu JH, Lichtenstein AH, Costello RB, et al. Global burden of hypertension: analysis of worldwide data. Ridaura VK, Faith JJ, Rey FE, Cheng J, Duncan AE, Kau AL, et al. Epidemiological studies have found that the Mediterranean dietary pattern has preventive and protective effects against cardiovascular diseases [16,17], whereas the Western-style dietary pattern is positively associated with dyslipidemia, obesity, hypertension, atherosclerosis, and diabetes [18,19]. However, there are numerous polyphenolic compounds present in plants, and these compounds likely have a wide range of biological activities and effects on human metabolism [65,66]. Living organisms can be categorized by the way in which the functions of food are carried out in their bodies.

Thus, organisms such as green plants and some bacteria that need only inorganic compounds for growth can be called autotrophic organisms; and organisms, including all animals, fungi, and most bacteria, that require both inorganic and organic compounds for growth are called heterotrophic. For example, the alternating light/dark photoperiod of the day-night cycles is important in setting endogenous circadian rhythms, which in turn are intimately linked to the regulation of metabolic activity . Nutrition transition refers to the shift of diet from traditional to modern along with an increase in sedentary behavior, that occur in conjunction with modernization. Aging is associated with the loss of metabolic efficiency caused by deterioration of cellular and genetic components resulting from chemical damage accumulated through life stages. The recent advent of CRISPR/Cas9-mediated gene editing will further simplify the creation of new animal models . Both nutrient deficiency (undernutrition) and nutrient excess (over-nutrition) cause the loss of nutrient/energy homeostasis and thus trigger cellular stress.
These patterns are the subject of this article.
They can be beneficial (e.g. Recent advances in high-throughput analysis have assisted in a better understanding of metabolism and revealed the active role of nutrients and their metabolites in regulating gene expression and cellular function.

In recent years, the upward trend is especially striking in developing countries where changes in diets and lifestyle accompany modernization [1,5].
Sex and aging determine the biological context and represent important modifiers of metabolic efficiency. In one scheme, organisms are classified according to the energy source they utilize.
Due to its location, the gut microbiota is exposed not only to the same extrinsic factors experienced by the host but also the metabolites and products produced by the host, such as bile acids, digestive enzymes, and other substances excreted into the gut. The gut microbiota represents an important interaction nexus for extrinsic and intrinsic factors that influence the metabolism of nutrients (Figure 1).

Rani S, Sreenivasaiah PK, Kim JO, Lee MY, Kang WS, Kim YS, et al. Effective cellular function depends on context, such as sex and age, as well as ideal supply of necessary nutrients. The non-nutrient components of food can be beneficial or non-beneficial. Tauroursodeoxycholic acid (TUDCA) attenuates pressure overload-induced cardiac remodeling by reducing endoplasmic reticulum stress. Certain amino acids have been shown to act as signaling molecules to regulate cellular growth and proliferation via mTOR (mechanistic target of rapamycin) [44,45], whose function has been implicated in many human diseases . Certain photosynthetic bacteria that cannot utilize water as the electron donor and require organic compounds for this purpose are called photoorganotrophs. Omics technologies (genomics, transcriptomics, proteomics, and metabolomics) provide a diverse and rich source of descriptive information needed for the detailed surveillance of nutrient metabolism in humans and experimental models .
The long-term consumption of these foods, which typically have poor nutrient diversity and excessive energy content, lead to deficiencies in key nutrients and excess fuel substrates that likely trigger the loss of cellular nutrient/energy homeostasis. This energy-rich compound is common to all cells. For a full discussion of the nutritional requirements of humans in particular, see the article nutrition, human. It is now evident that both extrinsic factors (such as food, xenobiotics, environment) and intrinsic factors (such as sex, age, gene variations), separately and cooperatively, influence nutrient metabolism and the risk for developing various metabolic diseases (Figure 1B). many food additives, and preservatives) or even toxic (e.g.
The .gov means its official. Extrinsic factors are important in dictating the efficiency of nutrient metabolism and health outcomes, including physical cues such as photoperiod and temperature. While every effort has been made to follow citation style rules, there may be some discrepancies.
However, these adaptive changes that alter cellular metabolism may contribute towards the loss of metabolic efficiency at the organismal level . Tada N, Maruyama C, Koba S, Tanaka H, Birou S, Teramoto T, et al. Before Kelly T, Yang W, Chen CS, Reynolds K, He J. Extrinsic factors also promote alterations of the epigenome which can have long-lasting impacts on nutrient and energy metabolism and contribute to the development of metabolic disorders in organs like the heart (e.g. Genetic variations impact on the efficacy of metabolic pathways by affecting the function and specific activities of membrane transporters, receptors, signaling proteins, enzymes, carrier proteins, transcription factors, and other proteins involved in the transport, sensing and processing of specific nutrients . In the meantime, consumption of foods with low-energy density and high nutrient diversity seems to be a prudent approach for minimizing cellular stress and the promotion of optimal cellular function and health.

Moreover, the gut microbiota may be capable of altering the susceptibility of its host to metabolic diseases, by transforming non-nutrient components of food into useful nutrients for the host. Nevertheless, there is evidence supporting the idea that calorie restriction is beneficial for longevity [26-28], providing support for the potential benefit of low-energy density diets (Figure 1A). Remodeling of the epigenome through life stages may also influence disease susceptibility in elderly individuals . Gut microbiota from twins discordant for obesity modulate metabolism in mice. There is also emerging evidence for the modulating effect of polyphenols on the composition and metabolic activity of gut microbiota that provides potential benefits to the host .

Males and females have distinct microbiomes, as do young and old individuals [62,88,89]. Let us know if you have suggestions to improve this article (requires login). The emergence of a highly infectious strain of Clostridium difficile is coincident with the introduction of trehalose into prepared foods, and it is suggested that this compound had permitted the selection and expansion of pathogenic strains by providing a carbon source and energy substrate not normally used by the non-pathogenic strain of this bacterium . It will be important to rigorously design these intervention trials so that these studies generate high quality data that are needed for reliable interpretations. Food is a complex combination of numerous components which can be classified into nutrients and non-nutrients. Over the last several decades, many jurisdictions around the world have witnessed the increasing prevalence of acquired metabolic syndromes, in particular obesity, diabetes, fatty liver disease and cardiovascular diseases [1-4].
In the case of a maladaptive response, programmed cell death is activated to remove malfunctioning cells. The benefits of consuming macronutrients are self-evident since their subunits serve as building blocks of cellular structures and as energy substrates in all organisms. Global burden of obesity in 2005 and projections to 2030, Global estimates of the prevalence of diabetes for 2010 and 2030, Obesity and the metabolic syndrome in developing countries. Animals, according to this classification, are chemoorganotrophs; i.e., they utilize chemical compounds to supply energy and organic compounds as electron donors. National Library of Medicine Bile acids aid in the absorption of dietary fats and lipid-soluble compounds, and also act as signaling molecules modulating macronutrient and energy metabolism, inflammatory responses, and detoxification through intracellular ligand-activated nuclear receptors . Importantly, the surplus of nutrients and energy induce endoplasmic reticulum stress and inflammatory responses that lead to systemic metabolic dysregulation [31,32].
Calorie restriction promotes mammalian cell survival by inducing the SIRT1 deacetylase, Sir2 mediates longevity in the fly through a pathway related to calorie restriction. It is commonly assumed that synthetic food additives (colorants, preservatives, sweeteners) do not have effects on metabolism, but this assumption should be tested regularly to ensure food safety.

Nutrients have been commonly regarded as nourishment, providing raw materials needed for cells growth and proliferation, and fuel for powering cellular metabolism.
Berger S, Raman G, Vishwanathan R, Jacques PF, Johnson EJ. For example, it provides materials that are metabolized to supply the energy required for the absorption and translocation of nutrients, for the synthesis of cell materials, for movement and locomotion, for excretion of waste products, and for all other activities of the organism. Detrimental environments, which include situations that induce the release of stress hormones, can impair the ability of the body to sense and respond to metabolic challenges [73-75]. A. High-fructose corn syrup: is this whats for dinner?

Due to the continued exposure of cells to stressors, the metabolic changes at the cellular level intended initially as adaptive strategies, persist and ultimately become the driver of metabolic dysfunction at the organismal level. The energy requirements of organisms can be measured in either joules or calories.
Many metabolic diseases caused by micronutrient deficiencies can be corrected by restoring the missing micronutrients in the diet [54,55]. These essential metabolites, along with minerals, make up a class of substances referred to as essential nutrients.
Jiang XC, Agellon LB, Walsh A, Breslow JL, Tall A. Dietary cholesterol increases transcription of the human cholesteryl ester transfer protein gene in transgenic mice. It is also becoming apparent that intake of diets with low-energy density but high in nutrient diversity may be the key to promoting and maintaining optimal health. The use of cells from both experimental animals and human donors can also highlight species-specific differences that impact on nutrition. Not all polyphenolic compounds are beneficial, as some compounds such as caffeic acid and genistein may be carcinogenic or genotoxic at high dosage [34,69,70].

Higher plants, for example, are photolithotrophic; i.e., they utilize light energy, with the inorganic compound water serving as the ultimate electron donor.
Some of the products generated from dietary fiber include short chain fatty acids (e.g., butyric and propionic acids) that are absorbed in the lower gut and serve as both energy substrates and regulators of host metabolism [63,64]. Piening BD, Zhou W, Contrepois K, Rost H, Gu Urban GJ, Mishra T, et al.
Fructose is known to stimulate de novo lipid synthesis in the liver and to induce endoplasmic reticulum stress in many cell types [40,41]. Fortunately, suites of mature bioinformatics tools and the necessary computing power are now available to decipher these data and infer relationships among genomes, metabolic processes, and cellular functions that are relevant to health and disease [88,100-102].
This might be partially due to retention of traditional dietary patterns, which promote consumption of foods with a wider array of nutrients and lower energy density [23-25].
