Smell & Taste Disorders

The Silent
Epidemic

Disorders of smell and taste are common, consequential, and largely invisible. Here is what the science shows — and why it deserves your attention.

01  —  The Scale
1in3

people will experience significant smell or taste dysfunction in their lifetime — and most never have a name for it.

27.5million

global COVID-19 cases linked to long-lasting sensory loss.

02  —  In the United States Adults 40+
20+ M Taste Alterations
Changes in basic taste perception
13+ M Smell Dysfunction
Reduced or absent ability to smell
10 M Anosmia
Complete inability to detect odors
03  —  Two Ways It Goes Wrong
Absence

Anosmia

The total loss of smell. The world goes quiet in a way few people around you will ever notice.

Distortion

Parosmia

Smell turns against you. Coffee reads as rot; the familiar becomes intolerable. Not absence, but betrayal.

04  —  Why It Matters
75–95%

Most of flavor is smell, not taste.

The tongue reads only sweet, salt, sour, bitter and savory. Everything else we call “flavor” — three-quarters of it or more — arrives through the nose. Lose smell, and the table goes flat.

An Early Warning

Smell loss can be among the first signs of Alzheimer's and Parkinson's — appearing years before memory or movement. It is not a minor inconvenience. It is a signal.

05  —  Reclaiming the Table

When aroma fades, three things still carry a meal. Lean on them.

01

Crunch

Texture and sound add a dimension the nose no longer can.

02

Temperature

Hot against cold sharpens contrast and brings food alive.

03

Umami

Savory depth carries a dish when aroma falls away.
