How often do taste buds regenerate and can you change your sense of taste?

The answer

Human taste buds contain 50-100 taste receptor cells that regenerate every 10-14 days from basal stem cells - one of the fastest cellular turnover rates in the body. Adults have approximately 2,000-10,000 taste buds, with 'supertasters' having up to twice the density of fungiform papillae. Each taste bud detects all five basic tastes: sweet, salty, sour, bitter, and umami - the old 'tongue map' assigning regions to specific tastes was debunked in 1974. Taste perception genuinely changes with age: children have more bitter receptors (explaining vegetable aversion), and adults lose roughly 50% of taste buds by age 60. Chemotherapy, zinc deficiency, and COVID-19 can damage taste receptor cells, though most regenerate within weeks. Miraculin, a protein from miracle berries, binds to sweet receptors and makes sour foods taste intensely sweet for up to two hours.
