Midlife coffee consumption in general was associated with a decreased late life dementia risk, while caffeine intake in particular was associated with a decelerated cognitive decline. The consumption of coffee has been reported to be linked with a decreased dementia risk. Taken together, caffeine can increase metabolic activity and therefore promote cell proliferation via providing higher energy levels to the cells. An increase in lipolysis results in a stimulation of cell metabolism due to higher levels of energy. PDEs regulate cyclic nucleotide signaling and are coupled to diverse physiological functions: Inhibition of PDE increases intracellular concentrations of cyclic adenosine monophosphate (cAMP), which in turn activates several enzymes and transcription factors linked to fat oxidation and lipolysis. Additionally, caffeine inhibits intracellular phosphodiesterase (PDE) enzymes. As caffeine acts as an antagonist of AR, it can, for example, indirectly affect the release of neurotransmitters, including dopamine, acetylcholine, serotonin, and gamma-aminobutyric acid (GABA). The AR-ligand adenosine regulates the release of neurotransmitters in the brain and modulates myocardial oxygen consumption and blood flow in the heart. ARs are located in the central and peripheral nervous system as well as in various body organs and compartments, such as the heart and blood vessels. The stimulating effects of caffeine after ingestion are primarily mediated via adenosine receptors (ARs). In addition, various pharmaceutical products contain caffeine including over-the-counter pain and weight-loss medications and numerous prescription drugs, including Midol® to treat menstrual symptoms, Vanquish® for headache and general pain relief, orphenadrine as a prescription muscle pain medication, and Fiorinal® and Synalgos®-DC as prescription headache medications. The caffeine content ranges from as little as 2 mg caffeine per 100 mL in beverages based on cocoa powder to as much as 200 mg of caffeine per 100 mL of strong espresso coffee. It is a well-known component of coffee and green and black tea as well as chocolate and is used as a food additive, for example, in soft drinks or bottled water. Caffeine is consumed in beverages and foods. This plant secondary metabolite belongs to the group of xanthine alkaloids and is found in more than 60 different plant species but can also be produced synthetically. ![]() ![]() Caffeine is the most widely consumed psychoactive or central nervous system (CNS) stimulant in the world.
