Summary
Anorectic patients have fewer fungiform papillae (fPap) and reduced 6-n-propylthiouracil (PROP) bitter taste sensitivity. This suggests a link between taste perception, fPap number, and eating disorder development.
Area of Science:
- Neuroscience
- Genetics
- Physiology
Context:
- Taste perception is a hereditary trait influencing dietary habits.
- Fungiform papillae (fPap) on the tongue are crucial for taste information.
- Eating disorders significantly impact an individual's relationship with food and body image.
Purpose:
- To investigate the relationship between the number of fungiform papillae (fPap), 6-n-propylthiouracil (PROP) sensitivity, and body mass index (BMI) in patients with eating disorders.
- To compare these factors between individuals with anorexia nervosa, bulimia nervosa, and healthy controls.
Summary:
- The study included 18 female patients (anorexia or bulimia nervosa) and 15 age-matched female controls.
- fPap count and PROP sensitivity were assessed. Results showed anorectic patients had significantly fewer fPap compared to controls and bulimic patients, particularly among non-tasters (PROP negative).
- No significant difference in fPap was found between tasters and non-tasters within groups, though a trend towards higher BMI was observed in bulimic and healthy non-tasters.
Impact:
- A reduced number of fPap is associated with decreased PROP sensitivity in anorectic patients, a novel finding.
- Variations in fPap number and PROP sensitivity may influence the pathophysiology of eating behavior and taste perception.
- These findings contribute to understanding the development of eating disorders and the role of sensory processing.

Taste Buds and Receptors
Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...
Conditioned Taste Aversion
Conditioned taste aversion, also known as sauce béarnaise syndrome, is a phenomenon in which an individual develops an aversion to a certain food taste following a negative experience, typically illness. This form of aversion is a type of classical conditioning in which the taste of the food (conditioned stimulus, CS) is associated with the experience of illness (unconditioned stimulus, UCS).
A notable characteristic of conditioned taste aversion is that it often requires only a single exposure...

The Physiology of Taste
The perception of a salty flavor is facilitated by sodium ions within the oral salivary fluid. Upon consumption of a salty substance, salt crystals disassemble, leading to the liberation of its constituents—Na+ and Cl- ions. These ions subsequently dissolve into the salivary fluid present in the oral cavity. The external environment of the gustatory cells experiences an elevation in Na+ concentration, thereby establishing a potent concentration gradient. This gradient propels the diffusion of...
Gustation
Gustation is a chemical sense that, along with olfaction (smell), contributes to our perception of taste. It starts with the activation of receptors by chemical compounds (tastants) dissolved in the saliva. The saliva and filiform papillae on the tongue distribute the tastants and increase their exposure to the taste receptors.
Bulimia Nervosa
Bulimia nervosa is a complex and severe eating disorder characterized by a cyclical pattern of binge-and-purge eating pattern. It generally involves an episode of binge eating, followed by compensatory behaviors such as vomiting, excessive exercise, laxative use, or fasting, to prevent weight gain. Despite often maintaining a normal weight, individuals with bulimia are intensely preoccupied with their body image and harbor an overwhelming fear of gaining weight. This can contribute to the...
Anorexia Nervosa
Anorexia nervosa is a complex and severe eating disorder characterized by an intense fear of weight gain, an unrelenting pursuit of thinness, and a distorted body image. It often leads to dangerously low body weight relative to an individual's age and height. This disorder is marked by significant physical and psychological consequences, making it one of the most life-threatening psychiatric illnesses.
