Smell-related causes
Colds, sinus problems, allergies, nasal polyps, and post-viral smell loss can reduce flavour because smell is a major part of how food is experienced.
Understanding taste loss
When taste changes,
food can feel unfamiliar
Taste loss can be confusing, frustrating, and sometimes frightening. This page explains why taste can change or disappear, how smell is often involved, and what may still be possible to detect and enjoy.
Possible causes
Why taste can change or disappear
Taste loss can be temporary, permanent, or somewhere in between. Sometimes the taste system is affected directly. Often, smell is reduced and flavour fades with it.
Medical causes
Neurological, autoimmune, metabolic, infectious, and salivary conditions can affect taste, smell, or both.
Physical or nerve-related causes
Head injury, surgery, nerve damage, stroke, and some brain-related conditions may disrupt taste pathways.
Chemical and treatment-related causes
Chemotherapy, radiotherapy, toxin exposure, and nutritional deficiencies can change how taste is detected or interpreted.
What may remain
What may still be detectable
Even when taste or smell is reduced, people may still detect useful food signals. These can become the foundation for making food feel more enjoyable again.
Basic tastes
Sweet, salty, sour, bitter, and umami may still be partly or fully detectable.
Sensation
Chilli heat, pepper warmth, mustard and wasabi sharpness, mint cooling, and tingling can often still be felt.
Texture & temperature
Crunch, creaminess, crispness, warmth, coldness, and contrast can help food feel satisfying.
Future recipe matching
Find food based on what you can still detect
This page will soon connect to a filterable Tasteless Cooking tool that suggests ingredients and recipes based on cause, detectable tastes, sensation, texture, temperature, and food preferences.
