Nutritional Value
Nutritional value or nutritive value as part of food quality is the measure of a well-balanced ratio of the essential nutrients carbohydrates, fat, protein, minerals, and vitamins in items of food or diet concerning the nutrient requirements of their consumer. Several nutritional rating systems and nutrition facts label The nutrition facts label (also known as the nutrition information panel, and other slight variations) is a label required on most convenience food, packaged food in many countries, showing what nutrients and other ingredients (to limit and get e ... have been implemented to rank food in terms of its nutritional value. International and national guidelines exist to inform consumers about optimal nutrient intake from their diets. On a biological scale, nutritive value of food may vary for different health conditions (leading to dietary recommendations and particular diet foods), seasonal differences, age, sexual differences, and interspecies or taxonomic dif ...

Food Quality
Food quality is a concept often based on the organoleptic characteristics (e.g., taste, aroma, appearance) and nutritional value of food. Producers reducing potential pathogens and other hazards through food safety practices is another important factor in gauging standards. A food's origin, and even its branding, can play a role in how consumers perceive the quality of products. Consumer acceptability of foods is typically based upon flavor and texture, as well as its color and smell. Safety The International Organization for Standardization identifies requirements for a producer's food safety management system, including the processes and procedures a company must follow to control hazards and promote safe products, through ISO 2200Federal and state level departments, specifically The Food and Drug Administration, are responsible for promoting public health by, among other things, ensuring food safety. Food quality in the United States is enforced by the Food Safety Act 1990. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nutrient
A nutrient is a substance used by an organism to survive, grow and reproduce. The requirement for dietary nutrient intake applies to animals, plants, fungi and protists. Nutrients can be incorporated into cells for metabolic purposes or excreted by cells to create non-cellular structures such as hair, scales, feathers, or exoskeletons. Some nutrients can be metabolically converted into smaller molecules in the process of releasing energy such as for carbohydrates, lipids, proteins and fermentation products ( ethanol or vinegar) leading to end-products of water and carbon dioxide. All organisms require water. Essential nutrients for animals are the energy sources, some of the amino acids that are combined to create proteins, a subset of fatty acids, vitamins and certain minerals. Plants require more diverse minerals absorbed through roots, plus carbon dioxide and oxygen absorbed through leaves. Fungi live on dead or living organic matter and meet nutrient needs from th ...

Food
Food is any substance consumed by an organism for Nutrient, nutritional support. Food is usually of plant, animal, or Fungus, fungal origin and contains essential nutrients such as carbohydrates, fats, protein (nutrient), proteins, vitamins, or Mineral (nutrient), minerals. The substance is Ingestion, ingested by an organism and assimilated by the organism's Cell (biology), cells to provide energy, maintain life, or stimulate growth. Different species of animals have different List of feeding behaviours, feeding behaviours that satisfy the needs of their metabolisms and have evolved to fill a specific ecological niche within specific geographical contexts. Omnivore, Omnivorous humans are highly adaptable and have adapted to obtaining food in many different ecosystems. Humans generally use cooking to prepare food for consumption. The majority of the food energy required is supplied by the industrial food industry, which produces food through Intensive farming, intensive agricu ...

Diet (nutrition)
In nutrition, diet is the sum of food consumed by a person or other organism. The word diet often implies the use of specific intake of nutrition for #Health, health or #Weight management, weight-management reasons (with the two often being related). Although humans are omnivores, each culture and each person holds some food preferences or some food taboos. This may be due to personal tastes or ethical reasons. Individual dietary choices may be more or less healthy. Complete nutrition requires ingestion and absorption of vitamins, Dietary mineral, minerals, essential amino acids from protein and essential fatty acids from fat-containing food, also food energy in the form of carbohydrate, protein, and fat. Dietary habits and choices play a significant role in the quality of life, health and longevity. Health A healthy diet can improve and maintain health, which can include aspects of mental and physical health. Specific diets, such as the DASH diet, can be used in treatment ...

Human Nutrition
Human nutrition deals with the provision of essential nutrients in food that are necessary to support human life and good health. Poor nutrition is a chronic problem often linked to poverty, food security, or a poor understanding of nutritional requirements. Malnutrition and its consequences are large contributors to deaths, physical deformities, and disabilities worldwide. Good nutrition is necessary for children to grow physically and mentally, and for normal human biological development. Recommended Dietary Allowances The Recommended Dietary Allowances (RDAs) are scientifically determined levels of essential nutrient intake, deemed sufficient by the Food and Nutrition Board to meet the nutritional needs of nearly all healthy individuals. The first RDA (nutrition), RDAs were published in 1943, during World War II, with the aim of setting standards for optimal nutrition. The initial editions outlined daily nutrient recommendations for various age groups, reflecting the l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nutritional Rating Systems
Nutritional rating systems are used to communicate the nutritional value of food in a more-simplified manner, with a ranking (or rating), than nutrition facts labels. A system may be targeted at a specific audience. Rating systems have been developed by governments, non-profit organizations, private institutions, and companies. Common methods include point systems to rank (or rate) foods based on general nutritional value or ratings for specific food attributes, such as cholesterol content. Graphics and symbols may be used to communicate the nutritional values to the target audience. Types Glycemic index Glycemic index is a ranking of how quickly food is metabolized into glucose when digested. It compares available carbohydrates gram-for-gram in foods to provide a numerical, evidence-based index of post prandial (post-meal) blood sugar level. The concept was introduced in 1981. The glycemic load of food is a number which estimates how much a food will raise a person's blood glucose ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nutrition Facts Label
The nutrition facts label (also known as the nutrition information panel, and other slight variations) is a label required on most convenience food, packaged food in many countries, showing what nutrients and other ingredients (to limit and get enough of) are in the food. Labels are usually based on official nutritional rating systems. Most countries also release overall List of nutrition guides, nutrition guides for general educational purposes. In some cases, the guides are based on different dietary targets for various nutrients than the labels on specific foods. Nutrition facts labels are one of many types of food labels required by regulation or applied by manufacturers. They were first introduced in the U.S. in 1994, and in the U.K. in 1996. Australia and New Zealand Australia and New Zealand use a nutritional information panel of the following format: Other items are included as appropriate, and the units may be varied as appropriate (e.g. substituting ml for g, or mmo ...

Diet Food
Diet food (or dietetic food) refers to any food or beverage whose recipe is altered to reduce fat, carbohydrates, and/or sugar in order to make it part of a weight loss program or Dieting, diet. Such foods are usually intended to assist in weight loss or a change in body type, although bodybuilding supplements are designed to increase weight. Terminology In addition to ''diet'' other words or phrases are used to identify and describe these foods including ''light'', ''zero calorie'', ''low calorie'', ''low fat'', ''no fat'' and ''sugar free''. In some areas use of these terms may be regulated by law. For example, in the U.S. a product labeled as "low fat" must not contain more than 3 grams of fat per serving; and to be labeled "fat free" it must contain less than 0.5 grams of fat per serving. Process The process of making a diet version of a food usually requires finding an adequate low-food-energy substitute for some high-food-energy ingredient. This can be as simple as replaci ...
