The bliss point is the amount of an ingredient such as salt, sugar or fat which optimizes deliciousness (in the formulation of food products).
Pioneering work on the bliss point was carried out by American market researcher and psychophysicist Howard Moskowitz, known for his successful work in product creation and optimization for foods ranging from spaghetti sauce to soft drinks. [1] Moskowitz used the term, bliss point, to describe "that sensory profile where you like food the most." [2] [3]
The bliss point for salt, sugar, or fat is a range within which perception is that there is neither too much nor too little, but the "just right" amount of saltiness, sweetness, or richness. The human body has evolved to favor foods delivering these tastes: the brain responds with a "reward" in the form of a jolt of endorphins, remembers what we did to get that reward, and makes us want to do it again, an effect run by dopamine, a neurotransmitter. The human body needs salt for balancing fluids, sugar for energy, and fat for composing the brain. [4] Besides the physical and taste need for sugar, salt, and fat, foods that contain high amounts of these ingredients are typically visually appealing. The visual appeal can override suppressing appetite hormones for many people to consume these goods. [5] Combinations of sugar, fat, and salt act synergistically, and are more rewarding than any one alone. In food product optimization, the goal is to include two or three of these nutrients at their bliss point. [6]
Applications of the bliss point in the food industry have been criticized for encouraging addiction-like behaviors around eating which may contribute to obesity and other health issues. [1] [6]
Using 9 experiments, the relationship between pleasantness, sweetness, and concentrations of various sugars was able to be determined. This was conducted by Howard R. Moskowitz at the Pioneering Research Laboratory. Using the results of his studies and those from other scientists, Moskowitz was able to provide some science behind the idea of Bliss Point.
Set up
During the first 7 experiments, 32 sugars were judged based on sweetness and pleasantness. This was done by separate groups of observers, chosen from a pool of 63 volunteers. For the eighth experiment only 10 sugars were judged by 12 observers. And for the final experiment, only glucose and tagatose were judged by 13 observers.
Scale
Each observer was trained to match numbers to stimuli based on apparent length and area. There was no restriction to the number scale. Therefore, the scientist has to standardize the modulus of each observer. The 5 glucose stimuli that were given to each observer were multiplied by a factor that made the mean equal to 10. This served as a standardized scale across all 9 experiments. Using this method guaranteed the ratios of each observer's judgments and the slope of the sweetness function, S = kC^n (S: sweetness, C: concentration, k: relative sweetness), was unaffected.
Results
All the results were analyzed through PSYCHOFIT, a computer program that provided summary statistics and least-squares estimates. The results showed that the relative sweetness of sugars changes across all concentrations similarly; meaning it is nontonic. The pleasantness of sugars are not monotonic with concentration. However, the results show they depart from linearity at the extremes of concentration. [7]

Around the world people purchase and consume foods and drinks that are engineered to create the bliss point sensation. This has led to increased rates of negative health effects like:
Sugar is the generic name for sweet-tasting, soluble carbohydrates, many of which are used in food. Simple sugars, also called monosaccharides, include glucose, fructose, and galactose. Compound sugars, also called disaccharides or double sugars, are molecules made of two bonded monosaccharides; common examples are sucrose, lactose, and maltose. White sugar is a refined form of sucrose. In the body, compound sugars are hydrolysed into simple sugars.
Fructose, or fruit sugar, is a ketonic simple sugar found in many plants, where it is often bonded to glucose to form the disaccharide sucrose. It is one of the three dietary monosaccharides, along with glucose and galactose, that are absorbed by the gut directly into the blood of the portal vein during digestion. The liver then converts both fructose and galactose into glucose, so that dissolved glucose, known as blood sugar, is the only monosaccharide present in circulating blood.

A sugar substitute is a food additive that provides a sweetness like that of sugar while containing significantly less food energy than sugar-based sweeteners, making it a zero-calorie or low-calorie sweetener. Artificial sweeteners may be derived through manufacturing of plant extracts or processed by chemical synthesis. Sugar substitute products are commercially available in various forms, such as small pills, powders, and packets.
Corn syrup is a food syrup which is made from the starch of corn/maize and contains varying amounts of sugars: glucose, maltose and higher oligosaccharides, depending on the grade. Corn syrup is used in foods to soften texture, add volume, prevent crystallization of sugar, and enhance flavor. It can be processed into high-fructose corn syrup (HFCS) by using the enzyme D-xylose isomerase to convert a large proportion of its glucose into sweeter fructose.
Chocolate milk is a type of flavoured milk made by mixing cocoa solids with milk. It is a food pairing in which the milk's mouthfeel masks the dietary fibres of the cocoa solids.
Convenience food is food that is commercially prepared for ease of consumption, and is usually ready to eat without further preparation. It may also be easily portable, have a long shelf life, or offer a combination of such convenient traits. Convenience foods include ready-to-eat dry products, frozen food such as TV dinners, shelf-stable food, prepared mixes such as cake mix, and snack food. Food scientists now consider most of these products to be ultra-processed foods and link them to poor health outcomes.
Inverted sugar syrup, also called invert syrup, invert sugar, simple syrup, sugar syrup, sugar water, bar syrup, syrup USP, or sucrose inversion, is a syrup mixture of the monosaccharides glucose and fructose, that is made by hydrolytic saccharification of the disaccharide sucrose. This mixture's optical rotation is opposite to that of the original sugar, which is why it is called an invert sugar.
Chocolate addiction is a compulsive desire to eat chocolate despite negative consequences.
The subjective sweetness of a wine is determined by the interaction of several factors, including the amount of sugar in the wine, but also the relative levels of alcohol, acids, and tannins. Sugars and alcohol enhance a wine's sweetness, while acids cause sourness and bitter tannins cause bitterness. These principles are outlined in the 1987 work by Émile Peynaud, The Taste of Wine.
Bioenergetics is a field in biochemistry and cell biology that concerns energy flow through living systems. This is an active area of biological research that includes the study of the transformation of energy in living organisms and the study of thousands of different cellular processes such as cellular respiration and the many other metabolic and enzymatic processes that lead to production and utilization of energy in forms such as adenosine triphosphate (ATP) molecules. That is, the goal of bioenergetics is to describe how living organisms acquire and transform energy in order to perform biological work. The study of metabolic pathways is thus essential to bioenergetics.
Hyperinsulinemia is a condition in which there are excess levels of insulin circulating in the blood relative to the level of glucose. While it is often mistaken for diabetes or hyperglycaemia, hyperinsulinemia can result from a variety of metabolic diseases and conditions, as well as non-nutritive sugars in the diet. While hyperinsulinemia is often seen in people with early stage type 2 diabetes mellitus, it is not the cause of the condition and is only one symptom of the disease. Type 1 diabetes only occurs when pancreatic beta-cell function is impaired. Hyperinsulinemia can be seen in a variety of conditions including diabetes mellitus type 2, in neonates and in drug-induced hyperinsulinemia. It can also occur in congenital hyperinsulinism, including nesidioblastosis.
High-fructose corn syrup (HFCS), also known as glucose–fructose, isoglucose and glucose–fructose syrup, is a sweetener made from corn starch. As in the production of conventional corn syrup, the starch is broken down into glucose by enzymes. To make HFCS, the corn syrup is further processed by D-xylose isomerase to convert some of its glucose into fructose. HFCS was first marketed in the early 1970s by the Clinton Corn Processing Company, together with the Japanese Agency of Industrial Science and Technology, where the enzyme was discovered in 1965.
Industrial fermentation is the intentional use of fermentation in manufacturing processes. In addition to the mass production of fermented foods and drinks, industrial fermentation has widespread applications in chemical industry. Commodity chemicals, such as acetic acid, citric acid, and ethanol are made by fermentation. Moreover, nearly all commercially produced industrial enzymes, such as lipase, invertase and rennet, are made by fermentation with genetically modified microbes. In some cases, production of biomass itself is the objective, as is the case for single-cell proteins, baker's yeast, and starter cultures for lactic acid bacteria used in cheesemaking.
Isomaltulose is a disaccharide carbohydrate composed of glucose and fructose. It is naturally present in honey and sugarcane extracts and is also produced industrially from table sugar (sucrose) and used as a sugar alternative.
The gustatory system or sense of taste is the sensory system that is partially responsible for the perception of taste (flavor). Taste is the perception stimulated when a substance in the mouth reacts chemically with taste receptor cells located on taste buds in the oral cavity, mostly on the tongue. Taste, along with the sense of smell and trigeminal nerve stimulation, determines flavors of food and other substances. Humans have taste receptors on taste buds and other areas, including the upper surface of the tongue and the epiglottis. The gustatory cortex is responsible for the perception of taste.
Howard Moskowitz is an American market researcher and psychophysicist. He is known for the detailed study he made of the types of spaghetti sauce and horizontal segmentation. By providing a large number of options for consumers, Moskowitz pioneered the idea of intermarket variability as applied to the food industry.
Added sugars or free sugars are sugar carbohydrates added to food and beverages at some point before their consumption. These include added carbohydrates, and more broadly, sugars naturally present in honey, syrup, fruit juices and fruit juice concentrates. They can take multiple chemical forms, including sucrose, glucose (dextrose), and fructose.
Pure, White and Deadly is a 1972 book by John Yudkin, a British nutritionist and former Chair of Nutrition at Queen Elizabeth College, London. Published in New York, it was the first publication by a scientist to anticipate the adverse health effects, especially in relation to obesity and heart disease, of the public's increased sugar consumption. At the time of publication, Yudkin sat on the advisory panel of the British Department of Health's Committee on the Medical Aspects of Food and Nutrition Policy (COMA). He stated his intention in writing the book in the last paragraph of the first chapter: "I hope that when you have read this book I shall have convinced you that sugar is really dangerous."
Salt Sugar Fat: How the Food Giants Hooked Us is a book by Michael Moss published by Random House in 2013 that won the James Beard Foundation Award for Writing and Literature in 2014. It also was a number one New York Times bestseller in 2013.
