The science behind the experience and which is the best coffee for your health
Coffee is, for many, a daily ritual. However, there are times when a cup makes us run to the bathroom faster than we expected. If this has happened to you, you're not alone. In this article, we'll break down what causes certain coffees to trigger this effect, why the type of bean you choose can influence it, and what the best coffee is to enjoy without digestive worries.The chemistry of coffee:
The culprit is caffeine (and more)
The main factor behind that rush to the bathroom is caffeine, a stimulant that not only wakes you up but also activates your digestive system. However, caffeine isn't alone in this: the acids and oils present in coffee can also have a significant impact on how your gut responds. These compounds, such as chlorogenic acids, contribute to that accelerated bowel movement.
Variety matters: Robusta or Arabica?
Not all coffees are created equal. If you've noticed that certain coffees affect you more than others, you may be drinking Robusta coffee, one of the most common varieties but also one of the most problematic. Robusta has almost twice the caffeine of Arabica , and this can have a direct impact on your digestion. Additionally, the caffeine in Robusta beans tends to be more aggressive on the nervous and digestive systems.On the other hand, Arabica coffee, grown at higher altitudes, not only has less caffeine, but is also generally gentler on the stomach due to its more refined flavor profile.
The impact of roasting: How does it affect the digestive system?
Roasting also plays a significant role in how coffee affects your body. Dark roast coffees tend to have less caffeine than light roasts, but they also contain more oils and compounds that can irritate the stomach. On the other hand, light roast coffees can be more acidic, which could also be a trigger for that sudden "urge."
For those seeking balance, a medium roast is the most recommended. This type of coffee preserves the aromatic compounds of the bean without being too harsh on the digestive system. 
What type of coffee should you choose?
To avoid the unwanted effects of coffee, your best option is a medium-roasted Arabica coffee. Not only does it contain less caffeine than Robusta, but it also offers a more balanced flavor experience, with less acidity and less digestive irritation. Additionally, Arabica beans are typically grown at higher altitudes, which contributes to their lower caffeine content and smoother profile.
