Why does everything you eat taste bad?

If everything you eat tastes bad, it could be due to several factors, such as a loss of taste sensitivity from illness, medication side effects, or nutritional deficiencies. Psychological factors like stress or depression can also alter your perception of flavors. Additionally, certain conditions like anosmia (loss of smell) can significantly impact taste, as smell is crucial for flavor perception. If this persists, it's advisable to consult a healthcare professional to identify the underlying cause.
