Forget cutlery: what science has discovered about eating with your hands will blow your mind

We often think that taste is only on the tongue, but eating involves all the senses - and touch is one of them. When we touch food, the brain starts processing information long before the first bite: temperature, texture, humidity, crunchiness. All this activates areas related to pleasure and anticipation.

A study in the Journal of Retailing and Consumer Services showed that people who touch food before eating feel the taste more intensely and have a more pleasurable experience. The simple physical contact awakens a sense of "ownership" and involvement with what will be consumed. It's as if the brain understands: "this is mine, and I want to enjoy every bit of it".

Long before forks and knives were invented, eating with your hands was the norm. People from India, Africa, the Middle East and Southeast Asia still maintain this custom - and not for lack of cutlery, but out of tradition and philosophy.

In Indian culture, for example, it is believed that the five fingers represent the five elements of nature (earth, water, fire, air and ether). Eating with your hands is therefore an act of connection between the body, the food and the universe. The idea is that by touching the food, you become more aware of what you are ingesting, which helps with digestion and quantity control.

But the knife and fork also play a role. The introduction of cutlery in Europe, between the 16th and 17th centuries, came with the advancement of etiquette and hygiene standards. Eating with your hands began to be seen as a "rustic" gesture, and utensils gained a status of sophistication and control.

In a way, cutlery creates a distance between you and the food. This distance can diminish the emotional and sensory involvement with the food - after all, touch is mediated by metal, and the brain doesn't feel texture directly. On the other hand, cutlery allows for more precise cuts, helps with presentation and, of course, is indispensable in formal contexts.

Neuroscience research shows that the pleasure of eating is linked to sensory expectation. When you see, smell and touch food, the brain releases dopamine - the pleasure hormone - even before chewing. Eating with your hands enhances this sequence, making the moment more engaging and satisfying.

In addition, there is evidence that people who eat with their hands eat less. This is because the process is slower and more conscious: you have to pick it up, feel it and put it in your mouth, which increases the perception of satiety. In other words, as well as being more pleasurable, it can be a habit that helps control eating habits.

The same dish can taste different depending on how and where it is eaten. A hamburger eaten with your hands in the car tastes different from the same hamburger cut with a knife and fork in a restaurant. This is because the context influences how the brain interprets the experience.

Eating with your hands is usually linked to informal, emotional and even nostalgic moments - parties, picnics, quick snacks. Cutlery, on the other hand, evokes situations of control, etiquette and convention. That's why the same food can seem "livelier" in one context and "more neutral" in another.
