Understanding Caffeine: What is it and How Does it Affect the Body?
Before we dive into the specifics of McDonald’s iced coffee, let’s take a closer look at caffeine and its effects on the body. Caffeine is a naturally occurring stimulant found in over 60 plant species, including coffee beans, tea leaves, and cacao pods. It’s a xanthine alkaloid compound that works by blocking the action of adenosine, a chemical that makes us feel tired.
When we consume caffeine, it’s absorbed into the bloodstream and eventually makes its way to the brain, where it binds to adenosine receptors. This binding process increases the activity of neurotransmitters like dopamine, norepinephrine, and acetylcholine, which can enhance alertness, energy, and energy.
However, excessive caffeine consumption can lead to negative side effects, such as:
- Jitters and shakiness
- Nervousness and anxiety
- Insomnia and disrupted sleep patterns
- Rapid heartbeat and palpitations
- Increased urine production
The American Academy of Sleep Medicine recommends that adults consume no more than 400 milligrams of caffeine per day, which is approximately the amount found in three to four cups of brewed coffee.
