Nutrient Profiling
Nutrient profiling, also nutritional profiling, is the science of classifying or ranking foods by their nutritional composition in order to promote health and prevent disease. A common use of nutrient profiling is in the creation of nutritional rating systems to help consumers identify nutritious food. A variety of nutrient profile models have been developed by academics, health organizations, national governments and the food industry. The development or selection of a model to use in food policy decisions is important, as different models can lead to different classifications of the same foods.

Food Composition Data
Food composition data (FCD) are detailed sets of information on the nutritionally important components of foods and provide values for energy and nutrients including protein, carbohydrates, fat, vitamins and minerals and for other important food components such as fibre. The data are presented in food composition databases (FCDBs). In the UK, FCD is listed in tables known as The Chemical Composition of Foods, McCance and Widdowson (1940)McCance RA & Widdowson EM (1940) The Chemical Composition of Foods, Medical Research Council Special Report Series No. 235. His Majesty’s Stationery Office: London. and in the first edition the authors stated that: ‘A knowledge of the chemical composition of foods is the first essential in the dietary treatment of disease or in any quantitative study of human nutrition’. This demonstrates the main reason for establishing FCD at that time. To this day, food composition studies remain central to nutrition research into the role of food componen ...

Health
Health, according to the World Health Organization, is "a state of complete physical, mental and social well-being and not merely the absence of disease and infirmity".World Health Organization. (2006)''Constitution of the World Health Organization''– ''Basic Documents'', Forty-fifth edition, Supplement, October 2006. A variety of definitions have been used for different purposes over time. Health can be promoted by encouraging healthful activities, such as regular physical exercise and adequate sleep, and by reducing or avoiding unhealthful activities or situations, such as smoking or excessive stress. Some factors affecting health are due to individual choices, such as whether to engage in a high-risk behavior, while others are due to structural causes, such as whether the society is arranged in a way that makes it easier or harder for people to get necessary healthcare services. Still, other factors are beyond both individual and group choices, such as genetic disorders. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Disease
A disease is a particular abnormal condition that negatively affects the structure or function of all or part of an organism, and that is not immediately due to any external injury. Diseases are often known to be medical conditions that are associated with specific signs and symptoms. A disease may be caused by external factors such as pathogens or by internal dysfunctions. For example, internal dysfunctions of the immune system can produce a variety of different diseases, including various forms of immunodeficiency, hypersensitivity, allergies and autoimmune disorders. In humans, ''disease'' is often used more broadly to refer to any condition that causes pain, dysfunction, distress, social problems, or death to the person affected, or similar problems for those in contact with the person. In this broader sense, it sometimes includes injuries, disabilities, disorders, syndromes, infections, isolated symptoms, deviant behaviors, and atypical variations of structur ...

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 Food Compass Food Compass is a nutrient profiling system which ranks foods based on their healthfulness using characteristics that impact health in positive or negative ways. It was developed at Tufts University. 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 nume ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Junk Food
"Junk food" is a term used to describe food that is high in calories from sugar and/or fat, and possibly also sodium, but with little dietary fiber, protein, vitamins, minerals, or other important forms of nutritional value. It is also known as HFSS food (high in fat, salt and sugar). The term ''junk food'' is a pejorative dating back to the 1950s. Precise definitions vary by purpose and over time. Some high-protein foods, like meat prepared with saturated fat, may be considered junk food. Fast food and fast food restaurants are often equated with junk food, although fast foods cannot be categorically described as junk food. Most junk food is highly processed food. Concerns about the negative health effects resulting from a junk food-heavy diet, especially obesity, have resulted in public health awareness campaigns, and restrictions on advertising and sale in several countries. Current studies indicate that a diet high in junk food can increase the risk of depression, digestive i ... [...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 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 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 mmol for mg in the 'Sodium' row).
