Caffeine and the Fish Free Diet

Caffeine is a central nervous system stimulant that naturally occurs in coffee beans, tea leaves, kola nuts, and cacao pods. It is widely consumed worldwide in beverages like coffee, tea, energy drinks, and soft drinks, and is also found in some medications and supplements. Caffeine works by blocking the action of adenosine, a brain chemical involved in sleep, leading to increased alertness and wakefulness.
