Is Coffee Paleo? No.
But wait…If you drink it black you will not be deducted any points, as soon as you sneek in the cream subtract 1point from your scoring sheet!
Coffee is the second most popular drink in the world, trailing only water and, debatably, tea.
Caffeine, a key component of coffee, is a controversial compound. With 90% of North American adults consuming caffeine daily, it is the world’s most consumed psychoactive drug – and coffee is the delivery method of choice.
But is coffee really bad for us? Should we give up our beloved cuppa joe? If it’s bad, why does it feel so good?
Research on coffee’s safety is mixed, for several reasons:
- Metabolism matters. People vary genetically in how well they can process caffeine and coffee.
- Coffee interacts with many hormones and neurotransmitters in the body, such as cortisol, acetylcholine, and insulin. These relationships are complex, and often depend on timing, amount, and people’s individual makeup.
- As a crop, coffee is less like corn or soy, and more like cacao or wine grapes: It’s typically grown and processed in smaller batches by smaller-scale farmers and producers. You can follow along with his process here or see a nice PDF version here.)
So it’s hard to say definitively that coffee is “good” or “bad”; “healthy” or “unhealthy”. Let’s explore this in more depth.
What about cortisol?
Cortisol is a hormone produced by the adrenal glands. It increases blood pressure, spikes blood sugar and prepares the body for “fight or flight” mode.
Coffee and caffeine tend to transiently increase cortisol levels; however, this depends on several factors, including when you drink coffee, how often you drink it, and whether you have high blood pressure.
Cortisol is normally high in the morning, so if you drink some coffee at 6 a.m. and 10 a.m., you should be fine, as cortisol is naturally elevated at that time of day anyway. However, your body may not appreciate coffee as much in the afternoon or evening, when cortisol normally drops. At that point, consider tea or something decaffeinated.
