The overall nutritional quality index was a nutritional rating system developed at the Yale-Griffin Prevention Research Center in 2008. A proprietary algorithm assigned foods a score between 1 and 100 intended to reflect the overall nutritional value a portion of the given food provided. [1] The system was marketed commercially as NuVal by NuVal, LLC, a joint venture with Topco Associates. [2] Over 1600 grocery stores in the United States placed NuVal scores on product shelf tags next to the price. [3] [2] The commercial product was discontinued in 2017 amid accusations of conflicts of interest and criticism of NuVal LLC's refusal to publish the algorithm. [4] Either of which may have contributed to some inconsistencies in scoring where certain processed foods scored higher than, for instance, canned fruits and vegetables. [4]
The algorithm considers thirty nutrient factors, like the relative portions of vitamins, sugar, saturated fat, and trans fats and the quality of the protein and fat, [5] and produces a score from one to 100. Higher scores represent greater overall nutritional value. However, the actual algorithm, including the relative weights of the nutrients, was never disclosed to the public. [4]
Broccoli, blueberries, okra, oranges, and green beans were some foods that received the best score (100) while ice pops and soft drinks received the worst (1). [1]
In nutrition, biology, and chemistry, fat usually means any ester of fatty acids, or a mixture of such compounds, most commonly those that occur in living beings or in food.
"Junk food" is a term used to describe food that is high in calories from sugar and/or fat, and possibly sodium, making it hyperpalatable, but with little dietary fiber, protein, vitamins, minerals, or other important forms of nutritional value. It is also known as HFSS food. The term junk food is a pejorative dating back to the 1950s. Many variations of junk food can be easily found in most supermarkets and fast food restaurants. Due to easy accessibility, commercially-oriented packaging, and often-low prices, people are most likely to consume it.
Coconut oil is an edible oil derived from the kernels, meat, and milk of the coconut palm fruit. Coconut oil is a white solid fat below around 25 °C (77 °F), and a clear thin liquid oil in warmer climates. Unrefined varieties have a distinct coconut aroma. Coconut oil is used as a food oil, and in industrial applications for cosmetics and detergent production. The oil is rich in medium-chain fatty acids.
A saturated fat is a type of fat in which the fatty acid chains have all single bonds. A fat known as a glyceride is made of two kinds of smaller molecules: a short glycerol backbone and fatty acids that each contain a long linear or branched chain of carbon (C) atoms. Along the chain, some carbon atoms are linked by single bonds (-C-C-) and others are linked by double bonds (-C=C-). A double bond along the carbon chain can react with a pair of hydrogen atoms to change into a single -C-C- bond, with each H atom now bonded to one of the two C atoms. Glyceride fats without any carbon chain double bonds are called saturated because they are "saturated with" hydrogen atoms, having no double bonds available to react with more hydrogen.
Hemp oil is oil obtained by pressing hemp seeds. Cold pressed, unrefined hemp oil is dark to clear light green in color, with a nutty flavor. The darker the color, the grassier the flavour. It should not be confused with hash oil, a tetrahydrocannabinol-containing oil made from the Cannabis flower.
Low-carbohydrate diets restrict carbohydrate consumption relative to the average diet. Foods high in carbohydrates are limited, and replaced with foods containing a higher percentage of fat and protein, as well as low carbohydrate foods.
The Weston A. Price Foundation (WAPF), co-founded in 1999 by Sally Fallon (Morell) and nutritionist Mary G. Enig, is a U.S. 501(c)(3) nonprofit organization dedicated to "restoring nutrient-dense foods to the American diet through education, research and activism".
Oleic acid is a fatty acid that occurs naturally in various animal and vegetable fats and oils. It is an odorless, colorless oil, although commercial samples may be yellowish. In chemical terms, oleic acid is classified as a monounsaturated omega-9 fatty acid, abbreviated with a lipid number of 18:1 cis-9, and a main product of Δ9-desaturase. It has the formula CH3−(CH2)7−CH=CH−(CH2)7−COOH. The name derives from the Latin word oleum, which means oil. It is the most common fatty acid in nature. The salts and esters of oleic acid are called oleates. It is a common component of oils, and thus occurs in many types of food, as well as in soap.
Omega-6 fatty acids are a family of polyunsaturated fatty acids that have in common a final carbon-carbon double bond in the n-6 position, that is, the sixth bond, counting from the methyl end.
Cat food is food specifically designed for consumption by cats. As obligate carnivores, cats have specific requirements for their dietary nutrients, namely nutrients found only in meat or synthesised, such as taurine and Vitamin A. Certain nutrients, including many vitamins and amino acids, are degraded by the temperatures, pressures and chemical treatments used during manufacture, and hence must be added after manufacture to avoid nutritional deficiency. Cat food is typically sold as dry kibble, or as wet food in cans and pouches.
Peanut oil, also known as groundnut oil or arachis oil, is a vegetable oil derived from peanuts. The oil usually has a mild or neutral flavor but, if made with roasted peanuts, has a stronger peanut flavor and aroma. It is often used in American, Chinese, Indian, African and Southeast Asian cuisine, both for general cooking and in the case of roasted oil, for added flavor. Peanut oil has a high smoke point relative to many other cooking oils, so it is commonly used for frying foods.
A healthy diet is a diet that maintains or improves overall health. A healthy diet provides the body with essential nutrition: fluid, macronutrients such as protein, micronutrients such as vitamins, and adequate fibre and food energy.
Sunflower oil is the non-volatile oil pressed from the seeds of the sunflower. Sunflower oil is commonly used in food as a frying oil, and in cosmetic formulations as an emollient.
The nutrition facts label is a label required on most packaged food in many countries, showing what nutrients and other ingredients 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.
Nutritional rating systems are used to communicate the nutritional value of food in a more-simplified manner, with a ranking, 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 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.
Fat, Sick and Nearly Dead is a 2010 American documentary film which follows the 60-day journey of Australian Joe Cross across the United States as he follows a juice fast to regain his health under the care of Joel Fuhrman, Nutrition Research Foundation's Director of Research.
David L. Katz is an American physician, nutritionist and writer. He was the founding director of the Yale-Griffin Prevention Research Center that was founded at Griffin Hospital in 1998. Katz is the founder of True Health Initiative and is an advocate of plant-predominant diets.
The Nutri-Score, also known as the 5-Colour Nutrition label or 5-CNL, is a five-colour nutrition label and nutritional rating system, and an attempt to simplify the nutritional rating system demonstrating the overall nutritional value of food products. It assigns products a rating letter from A (best) to E (worst), with associated colors from green to red.
The Health Star Rating System (HSR) is an Australian and New Zealand Government initiative that assigns health ratings to packaged foods and beverages. The purpose for the Health Star Rating is to provide a visual comparison of like for like products, to assist consumers into distinguishing and choosing the healthier options. It was designed to target time-deprived working adults as well as parents and children who were less likely to check how healthy each individual product was, through examination of the nutritional facts label on the back of products.
Rapeseed oil is one of the oldest known vegetable oils. There are both edible and industrial forms produced from rapeseed, the seed of several cultivars of the plant family Brassicaceae. Historically, it was restricted as a food oil due to its content of erucic acid, which in laboratory studies was shown to be damaging to the cardiac muscle of laboratory animals in high quantities and which imparts a bitter taste, and glucosinolates, which made many parts of the plant less nutritious in animal feed. Rapeseed oil from standard cultivars can contain up to 54% erucic acid.
