Magnesium, required for processing atp and related reactions (builds bone, causes strong peristalsis, increases flexibility, increases alkalinity). Approximately 50 is in bone, the remaining 50 is almost all inside body cells, with only about 1 located in extracellular fluid. Food sources include oats, buckwheat, tofu, nuts, caviar, green leafy vegetables, legumes, and chocolate. 17 18 Phosphorus, required component of bones; essential for energy processing. 19 Approximately 80 is found in inorganic portion of bones and teeth. Phosphorus is a component of every cell, as well as important metabolites, including dna, rna, atp, and phospholipids. Also important in pH regulation. Food sources include cheese, egg yolk, milk, meat, fish, poultry, whole-grain cereals, and many others.

14 Amino acids which an animal cannot synthesize on its own from smaller molecules are deemed essential. The paper synthesis of some amino acids can be limited garage under special pathophysiological conditions, such as prematurity in the infant or individuals in severe catabolic distress, and those are called conditionally essential. 14 a vegetarian diet can adequately supply protein, support pregnancy, childhood and athletic endeavors, 15 and lower the risk of cardiovascular disease and cancer. 16 Minerals edit main article: Mineral (nutrient) dietary minerals are the chemical elements required by living organisms, other than the four elements carbon, hydrogen, nitrogen, and oxygen that are present in nearly all organic molecules. The term "mineral" is archaic, since the intent is to describe simply the less common elements in the diet. Some are heavier than the four just mentioned including several metals, which often occur as ions in the body. Some dietitians recommend that these be supplied from foods in which they occur naturally, or at least as complex compounds, or sometimes even from natural inorganic sources (such as calcium carbonate from ground oyster shells). Some are absorbed much more readily in the ionic forms found in such sources. On the other hand, minerals are often artificially added to the diet as supplements; the most well-known is likely iodine in iodized salt which prevents goiter. Medical citation needed Essential dietary minerals edit include the following: medical citation needed Chlorine as chloride ions; very common electrolyte; see sodium, below.

Additionally, fiber, perhaps especially that from whole grains, may help way lessen insulin spikes and reduce the risk of type 2 diabetes. Citation needed Protein edit main article: Protein (nutrient) Proteins are the basis of many animal body structures (e.g. Muscles, skin, and hair) and form the enzymes which catalyse chemical reactions throughout the body. Each protein molecule is composed of amino acids which contain nitrogen and sometimes sulphur (these components are responsible for the distinctive smell of burning protein, such as the keratin in hair). The body requires amino acids to produce new proteins (protein retention) and to replace damaged proteins (maintenance). Amino acids are soluble in the digestive juices within the small intestine, where they are absorbed into the blood. Once absorbed, they cannot be stored in the body, so they are either metabolized as required or excreted in the urine. Medical citation needed Proteins consist of amino acids in different proportions. The most important aspect and defining characteristic of protein from a nutritional standpoint is its amino acid composition.

Soluble dietary fiber comprises a variety of oligosaccharides, waxes, esters, resistant starches, and other carbohydrates that dissolve or gelatinize in water. Many of these soluble fibers can be fermented or partially fermented by microbes in the human digestive system to produce short-chain fatty acids which are absorbed and therefore introduce some caloric content. Medical citation needed Whole grains, beans and other legumes, fruits (especially plums, prunes, and figs and vegetables are good sources of dietary fiber. Fiber writing is important to digestive health and is thought to reduce the risk of colon cancer. Citation needed for mechanical reasons, fiber can help in alleviating both constipation and diarrhea. Fiber provides bulk to the intestinal contents, and insoluble fiber especially stimulates peristalsis the rhythmic muscular contractions of the intestines which move digesta along the digestive tract. Some soluble fibers produce a solution of high viscosity ; this is essentially a gel, which slows the movement of food through the intestines.

Both dgla and aa can be made from the omega-6 linoleic acid (LA) in the human body, or can be taken in directly through food. An appropriately balanced intake of omega-3 and omega-6 partly determines the relative production of different prostaglandins: one reason a balance between omega-3 and omega-6 is believed important for cardiovascular health. In industrialized societies, people typically consume large amounts of processed vegetable oils, which have reduced amounts of the essential fatty acids along with too much of omega-6 fatty acids relative to omega-3 fatty acids. Medical citation needed fiber edit main article: dietary fiber dietary fiber is a carbohydrate, specifically a polysaccharide, which is incompletely absorbed in humans and in some animals. Like all carbohydrates, when it is metabolized, it can produce four Calories (kilocalories) of energy per gram, but in most circumstances, it accounts for less than that because of its limited absorption and digestibility. The two subcategories are insoluble and soluble fiber. Insoluble dietary fiber consists mainly of cellulose, a large carbohydrate polymer that is indigestible by humans, because humans do not have the required enzymes to break it down, and the human digestive system does not harbor enough of the types of microbes that can.

Dysregulation of protein synthesis and disease

Saturated fats, typically from animal sources, are next in order of preference, while trans fats are associated with a variety of disease and should be avoided. Saturated and some trans fats are typically solid at room temperature (such as butter or lard while unsaturated fats are typically liquids (such as olive oil or flaxseed oil ). Trans fats are very rare in nature, but have properties useful in the food processing industry, such as rancidity resistance. Citation needed most fatty acids are not essential, meaning the body can produce them as needed, generally from other fatty acids and always by expending energy to. However, in humans, at least two fatty acids are essential and must be included in the diet.

An appropriate balance of essential fatty acids omega-3 and omega-6 fatty acids seems also important for health, though definitive experimental demonstration has been elusive. Both of these "omega" long-chain polyunsaturated fatty acids are substrates for a class of eicosanoids known as prostaglandins, which have roles throughout the human body. They are hormones, in some respects. The omega-3 eicosapentaenoic acid (epa which can be made in the human body from the omega-3 essential fatty acid alpha-linolenic acid (lna or taken in through marine food sources, serves as a building block for series plan 3 prostaglandins (e.g. The omega-6 dihomo-gamma-linolenic acid (dgla) serves as a building block for series 1 prostaglandins (e.g. Anti-inflammatory pge1 whereas arachidonic acid (AA) serves as a building block for series 2 prostaglandins (e.g., pro-inflammatory pge 2).

The degree of causation is still not clear. Medical citation needed simple carbohydrates are absorbed quickly, and therefore raise blood-sugar levels more rapidly than other nutrients. However, the most important plant carbohydrate nutrient, starch, varies in its absorption. Gelatinized starch (starch heated for a few minutes in the presence of water) is far more digestible than plain starch, and starch which has been divided into fine particles is also more absorbable during digestion. The increased effort and decreased availability reduces the available energy from starchy foods substantially and can be seen experimentally in rats and anecdotally in humans.


Additionally, up to a third of dietary starch may be unavailable due to mechanical or chemical difficulty. Medical citation needed fat edit main articles: Fat and Nutrition  Fat A molecule of dietary fat typically consists of several fatty acids (containing long chains of carbon and hydrogen atoms bonded to a glycerol. They are typically found as triglycerides (three fatty acids attached to one glycerol backbone). Fats may be classified as saturated or unsaturated depending on the detailed structure of the fatty acids involved. Citation needed saturated fats have all of the carbon atoms in their fatty acid chains bonded to hydrogen atoms, whereas unsaturated fats have some of these carbon atoms double-bonded, so their molecules have relatively fewer hydrogen atoms than a saturated fatty acid of the same. Unsaturated fats may be further classified as monounsaturated (one double-bond) or polyunsaturated (many double-bonds). Furthermore, depending on the location of the double-bond in the fatty acid chain, unsaturated fatty acids are classified as omega-3 or omega-6 fatty acids. Trans fats are a type of unsaturated fat with trans -isomer bonds; these are rare in nature and in foods from natural sources; they are typically created in an industrial process called (partial) hydrogenation. Citation needed many studies have shown that consumption of unsaturated fats, particularly monounsaturated fats, is associated with better health in humans.

They are a diverse group of substances, with a range of chemical, physical and report physiological properties. 8 They make up a large part of foods such as rice, noodles, bread, and other grain -based products, 9 10 but they are not an essential nutrient, meaning a human does not need to eat carbohydrates. 11 Monosaccharides contain one sugar unit, disaccharides two, and polysaccharides three or more. Monosaccharides include glucose, fructose and galactose. 12 Disaccharides include sucrose, lactose, and maltose ; purified sucrose, for instance, is used as table sugar. 13 Polysaccharides, which include starch and glycogen, are often referred to as 'complex' carbohydrates because they are typically long multiple-branched chains of sugar units. The difference is that wallpaper complex carbohydrates take longer to digest and absorb since their sugar units must be separated from the chain before absorption. The spike in blood glucose levels after ingestion of simple sugars is thought to be related to some of the heart and vascular diseases, which have become more common in recent times. Simple sugars form a greater part of modern diets than in the past, perhaps leading to more cardiovascular disease.

Fats are triglycerides, made of assorted fatty acid monomers bound to a glycerol backbone. Some fatty acids, but not all, are essential in the diet: they cannot be synthesized in the body. Protein molecules contain nitrogen atoms in addition to carbon, oxygen, and hydrogen. 7 The fundamental components of protein are nitrogen-containing amino acids, some of which are essential in the sense that humans cannot make resume them internally. Some of the amino acids are convertible (with the expenditure of energy) to glucose and can be used for energy production just as ordinary glucose. By breaking down existing protein, some glucose can be produced internally; the remaining amino acids are discarded, primarily as urea in urine. This occurs naturally when atrophy takes place, or during periods of starvation. Citation needed carbohydrates edit main article: Carbohydrate Grain products: rich sources of complex and simple carbohydrates Carbohydrates may be classified as monosaccharides, disaccharides or polysaccharides depending on the number of monomer (sugar) units they contain.

to generate energy internally, and in either case it is measured in joules or kilocalories (often called "Calories" and written with a capital 'c' to distinguish them from little 'c' calories). Carbohydrates and proteins provide 17 kj approximately (4 kcal) of energy per gram, while fats provide 37 kJ (9 kcal) per gram, 5 though the net energy from either depends on such factors as absorption and digestive effort, which vary substantially from instance to instance. Vitamins, minerals, fiber, and water do not provide energy, but are required for other reasons. A third class of dietary material, fiber (i.e., nondigestible material such as cellulose seems also to be required, for both mechanical and biochemical reasons, though the exact reasons remain unclear. For all age groups, males need to consume higher amounts of macronutrients than females. In general, intakes increase with age until the second or third decade of life. 6 Molecules of carbohydrates and fats consist of carbon, hydrogen, and oxygen atoms. Carbohydrates range from simple monosaccharides (glucose, fructose, galactose) to complex polysaccharides (starch).

Any study done to determine nutritional status must take into account the wallpaper state of the body before and after experiments, as well as the chemical composition of the whole diet and of all the materials excreted and eliminated from the body (including urine and feces). Comparing food to waste material can help determine the specific compounds and elements absorbed and metabolized by the body. Medical citation needed, the effects of nutrients may only be discernible over an extended period of time, during which all food and waste must be analyzed. The number of variables involved in such experiments is high, making nutritional studies time-consuming and expensive, which explains why the science of human nutrition is still slowly evolving. Medical citation needed nutrients edit main article: Nutrient The seven major classes of nutrients are carbohydrates, fats, fiber, minerals, proteins, vitamins, and water. These nutrient classes are categorized as either macronutrients or micronutrients (needed in small quantities). The macronutrients are carbohydrates, fats, fiber, proteins, and water. 3 The micronutrients are minerals and vitamins.
