One of the basic premises of this nutritional theory is that many of the foods that humans eat today are not suitable for consumption due to the extensive preparation and processing methods utilized in today's kitchens. These foods, if eaten in their natural state, are ill-tasting, unchewable, and sometimes toxic to the human body. Without modern processing methods, these foods are, in effect, inedible. See also:

Nutrition is the study of the relationship between diet and states of health and disease. It is defined as the study of food. Absence of adequate nutrients can cause certain diseases to take hold that can potentially result in death. Between the extremes of optimal health and death from starvation or malnutrition, there is an array of disease states that can be caused or alleviated by changes in diet. Deficiencies, excesses and imbalances in the diet can produce negative impacts on health, which may result in diseases such as s ...

Ill health can be brought about by an imbalance of nutrients, producing either an excess or deficiency which in turn affects body functioning in a cumulative manner. Moreover, because most nutrients are, in some way or the other, involved in cell-to-cell signalling (e.g. as building block or part of a hormone or signalling 'cascades'), deficiency or excess of various nutrients affects hormonal function also indirectly. Thus, because they largely regulate the expression of genes, hormones represent a link between nutrition and how our ...

Those who follow this way of eating generally believe that: Raw foods contain enzymes which act as catalysts to regulate the digestive process in the body. Heating (or freezing) food degrades or destroys these enzymes in food. Food without enzymes is thought to lead in the longer term to toxicity in the body, to excess consumption of food, and therefore to obesity. Living and raw foods are thought to usually have much higher nut ...

Challenging issues in modern nutrition include: 'Artificial' interventions in food production and supply: Should genetic engineering be used in the production of food crops and animals?

Since the Industrial Revolution some two hundred years ago, the food processing industry has invented many technologies that both help keep foods fresh longer and alter the fresh state of food as they appear in nature. Cooling is the primary technology that can help maintain freshness, whereas many more technologies have been invented to allow foods to last longer without becoming spoiled. These latter technologies include pasteurisation, autoclavation, drying, salting, and separation of various components, and all appear to alter the origin ...

Nutrition - Calorie restriction. Lifespan may be somehow related to the amount of food energy consumed: this was first systematically investigated in the seminal study by Weidruch, et al. (1986). A pursuit of this principle of caloric restriction followed, involving research into longevity of those who reduced their food energy intake while attempting to optimize their micronutrient intake. Perhaps not surprisingly, some people found that cutting down on food reduced their quality of life so considerably as to ne ...

The human body comprises chemical compounds such as water, amino acids (proteins), fatty acids (lipids), nucleic acids (DNA/RNA), and carbohydrates (e.g. sugars). These compounds in turn consist of elements such as carbon, hydrogen, oxygen, nitrogen, and phosphorus, and may or may not contain minerals such as calcium, iron, and zinc. Minerals ubiquitously occur in the form of salts and electrolytes. All of these chemical compounds and elements occur in various forms and combinations (e.g. hormones/vitamins, phospholipids, hydroxyapatite), both in the human body and in organisms ( ...

Nutrition is very important for improving sports performance. The most common means to improve performance through diet is the practice of eating large quantities of protein, usually red meat, when attempting to build muscle mass; its efficacy is doubtful, as daily protein intake even on a normal diet usually outweighs the amount of muscle protein which can be synthesized in a day. To enhance their speed of muscle synthesis, athletes will focus a great deal on how to best accelerate their tissue recovery. Icing/heating the muscles to ...

Ankylosing spondylitis (AS) is a chronic, progressive inflammatory arthritis primarily affecting spine and sacroiliac joints, causing eventual fusion of the spine; it is a member of the group of the spondylarthropathies. Complete fusion results in a complete rigidity of the spine, a condition known as bamboo spine. Treatment is with physiotherapy and medication. Some cases remain mild, while other result in marked disability. Ankylosing spondylitis - Signs and symptoms. The typical patient is ...

Proponents of a raw food diet believe it dates to prehistoric eras, before humans discovered fire. Those who believe that prehistoric humans were largely non-carnivorous vegetarians believe that the human digestive system is largely configured to eat a mainly raw, mainly vegetarian diet, while those who believe their primitive ancestors to have been chiefly hunters, believe the opposite to be true. There are as many shades of variance between the two positions as there is historical evidence for a wide range of hunter gatherer activities, ra ...

The term Raw Food Diet, has come to embody as diverse a set of definitions as there are types of food. While most "'raw foodists'" are vegetarian or vegan, some are also carnivorous or omnivorous. Most of the foods consumed in a typical vegan raw food diet are fruits, vegetables, nuts, and seeds. The exact definition of raw food varies, but the general consensus is that a food has not been altered by any method which would alter the chemical structure, especially through cooking, freez ...

Leading proponents of the raw food movement currently include Doug Graham, Nora Lenz, Victoria Boutenko, Jinjee and Storm Talifero, Gabriel Cousens, Shazzie and Alissa Cohen. They have led thousands of people to become more aware of raw foodism through their lectures, books and web sites. Latter day proponents include Ann Wigmore (founder of the Hippocrates Health Institute, Arnold Ehret (author and authority on fasting), A Hovannessian and Norman Walker (who advocated the consumption of juices).

Most foods in raw food diets are simple in preparation, and can be eaten immediately. These include fruit and salads. Other foods can require considerable advanced planning to prepare for eating. Rice and some other grains, for example, require sprouting or overnight soaking to become edible. Preparation of gourmet raw food recipes usually call for a blender, food processor, juicer, and dehydrator. Depending on the recipe, some food (such as cakes) may need to be dehydrated. These processes, which emulate cooked food, are lengthy: some adherents of the diet consequently dispense with these foods, feeling that t ...
