Food is supposed to taste good. That is hardly controversial.
But what happens when “tasting good” becomes a measurable commercial target, when food scientists can systematically test different concentrations of sugar, salt and fat until they find the combination most likely to make consumers say, “This is perfect”?
That is the idea behind the “Bliss Point,” a term associated with American food scientist and market researcher Howard Moskowitz. In food science, it refers to the level of a taste-driving ingredient at which consumers’ liking reaches its peak. Too little may make a product seem bland. Too much can become unpleasant. Somewhere in between is the point at which the product produces the strongest sensory appeal.
And that seemingly simple idea has had enormous implications for the modern food industry.
The science of “just enough”
Imagine a company developing a new tomato ketchup.
Instead of simply deciding that the ketchup should contain “some sugar” and “some salt,” researchers can create multiple formulations. One might contain slightly less sugar, another slightly more. The same can be done with salt, acidity, spices, fat and other flavour components.
Consumers can then taste the different versions and rate how much they like each one.
The results can be plotted.
Perhaps the ketchup with the least sugar is perceived as too acidic. A slightly sweeter version receives better ratings. Another increase makes it even more appealing, but beyond a certain point, consumers begin to dislike it because it is excessively sweet.
The company has now identified a sweetness optimum.
The same principle can be applied to saltiness, richness and other sensory characteristics. Product developers can also manipulate texture, aroma, temperature, crunch and mouthfeel, creating a product whose different sensory components work together.
This is not necessarily sinister. Sensory testing is a legitimate part of food science. Companies need to know whether consumers actually like a product before putting it on supermarket shelves.
The concern begins when the pursuit of maximum palatability becomes intertwined with the commercial objective of encouraging repeated consumption.
From “tasty” to “crave inducing”
The distinction matters.
A food can be delicious without being deliberately designed to encourage excessive consumption. A bowl of rice can be delicious. So can a mango, a piece of grilled fish or a pot of soup.
The controversy surrounding modern processed foods is more specifically about formulations that combine multiple highly rewarding characteristics, particularly fat, refined carbohydrates or sugar, and sodium in ways that can make certain foods exceptionally palatable.
Researchers have developed definitions of what they call hyper-palatable foods, although there is still disagreement about precisely how the category should be defined and how strongly it predicts eating behaviour. One widely cited framework identified clusters involving combinations such as fat and sodium, fat and simple sugars, or carbohydrates and sodium.
This is where the bliss-point discussion becomes more complicated.
The goal is no longer simply to make a product acceptable.
It is to make the sensory experience extremely appealing.
Why sugar, salt and fat?
There is a biological reason these ingredients are particularly useful to food manufacturers.
Humans naturally respond positively to certain taste and nutrient signals. Sweetness can signal energy-rich carbohydrates. Salt is essential to the body and has a strong innate appeal. Fat contributes richness, texture and energy density.
Food scientists can therefore work with characteristics that humans already tend to find rewarding.
Research has long examined how highly palatable combinations of these components interact with the brain’s reward systems. However, it would be misleading to reduce the entire phenomenon to the simplistic claim that “sugar activates dopamine and therefore makes people addicted.” Human eating behaviour is considerably more complicated, involving biology, learning, environment, availability, habits, stress, culture and individual differences.
Still, the commercial incentive is obvious: if consumers consistently prefer one formulation over another, the preferred formulation has an economic advantage.
The supermarket is a laboratory of sorts
Consider a snack company preparing to launch a new potato chip.
Researchers might test different levels of saltiness. But salt is only one part of the equation.
How thick should the chip be?
How quickly should it break?
How much oil should remain on the surface?
How intense should the flavour be?
Should the seasoning arrive immediately or develop after chewing?
How much flavour should remain after swallowing?
These questions can all influence the sensory experience.
The result can be a product in which taste, aroma, texture and mouthfeel have been deliberately coordinated.
This is why the concept of food engineering extends beyond simply adding more sugar or salt. Modern food formulation is a sophisticated scientific discipline involving sensory science, chemistry, consumer research, texture analysis and statistical modelling.
The objective is often straightforward: make a product that consumers prefer.
But preference and health are not the same thing
This is where the ethical problem emerges.
A product can be extraordinarily appealing without being nutritionally beneficial.
The human appetite system evolved in an environment where highly concentrated combinations of energy, sugar and salt were relatively uncommon. Modern food manufacturing, by contrast, can produce these sensory characteristics cheaply, consistently and at enormous scale.
That creates a mismatch.
A person can consume a large amount of a highly palatable snack long before they consciously register how much energy they have consumed.
The customer becomes the product of optimization
The most troubling question is not whether companies should make food taste good.
It is how far companies should go in optimizing food for maximum consumer appeal, particularly when the products are marketed heavily to children and are inexpensive, convenient and widely available.
If a company discovers through thousands of taste tests that consumers prefer formulation A to formulation B, there is a powerful commercial reason to sell formulation A.
And if formulation A happens to encourage people to eat more of the product, that can translate into more sales.
It raises an uncomfortable question:
Should the food industry’s primary measure of success be how much people enjoy a product, or should nutritional quality and long-term health carry equal weight?
The implications go beyond individual choice
The argument that consumers should simply “exercise self-control” overlooks the environment in which those choices are made.
Highly engineered foods are not sitting quietly in one corner of a supermarket.
They are advertised. Discounted. Placed at checkout counters. Sold in schools and hawked on the street. Promoted through social media. Packaged in visually attractive portions. And designed for convenience.
The individual is therefore making choices inside an environment that has itself been carefully engineered.
This is particularly significant for children, whose food preferences are still developing.
So the responsible argument is not that one packet of crisps permanently rewires a child’s brain.
It is that children deserve a food environment in which commercial optimization does not override nutritional considerations.
The answer is not to make food bland
Food technology has enormous potential to improve people’s diets.
The same scientific expertise used to optimize sweetness could be used to reduce sugar while maintaining enjoyment. Fibre can be incorporated into products. Healthier ingredients can be made more appealing through better texture, flavour and preparation.
Indeed, the food industry is already being pushed toward reformulation in several countries as governments attempt to reduce populations’ exposure to excessive sugar, and saturated fat.
There is nothing wrong with wanting food to taste good.
There is something worth questioning when the sophistication of food science is directed overwhelmingly toward discovering the precise combination that maximizes consumer desire while nutritional quality becomes secondary.
The concept of the bliss point reveals something important about the modern food system; taste is no longer merely something that happens to food. It can be measured, modelled, tested and commercially optimized.
That knowledge can be used responsibly or irresponsibly.
Instead of asking only, “How do we make people want this food more?”, perhaps the better question is:
“How do we make nutritious food so satisfying that people want more of it?”
That would turn the science of food engineering in a very different direction, not toward exploiting our strongest cravings, but toward creating a food environment where health and pleasure do not have to be opposing goals.
