Coffee has been part of my morning routine ever since I was 12 years old. Recently, I became aware that conventional coffee contains a lot of pesticides. Is your coffee toxic? Let’s investigate.
Daily Coffee Habits: Why You Should Pay Attention
Most adults start off their day with a cup of coffee or two to wake them up and give them energy for the day. Drinking coffee in the morning has become a habit for me like brushing my teeth. If I am not able to drink a cup, my whole routine feels off. Often, many people will also drink more coffee in the afternoon when they are tired for an energy boost. When you are consuming something daily, especially multiple times a day, whatever is in that substance is going to accumulate in your body. So if you are drinking coffee that has been heavily sprayed with pesticides, those pesticides are slowly multiplying in your body and can damage your health.
How Pesticides in Coffee Can Harm Your Health
According to Frontiers in Public Health, “Due to the high consumption of coffee, both producers and consumers could be subjected to health risks due to pesticides in coffee, so attention should be drawn to the safety of coffee.” The organo-phosphorous pesticides sprayed on coffee obstruct a necessary enzyme. This enzyme (AChE) separates ACh into choline and acetic acid. When AChE is obstructed, your nervous system suffers. A study shows that exposure to these pesticides could possibly lead to Parkinson’s disease.
Are K-Cups Making Your Coffee More Toxic?
What is even worse than drinking toxic coffee? Brewing the coffee in plastic K cups! According to Science Direct, “the brewing process requires high temperature and pressure which can cause harmful endocrine disruptors to leach from the plastic in the capsules and machine into the coffee.” These chemicals from the plastic cup go into your bloodstream. A better option would be to purchase a Universal stainless-steel k Cup for your Keurig.
When hot water goes through plastic, it leaches microplastics and chemicals. And then we drink those microplastics and chemicals. Microplastics accumulate in the body and can negatively impact the digestive, respiratory, and endocrine systems.
When you consume microplastics, they can inflame the digestive tract, unsettle your gut microbiome, and lead to chemical toxicity. Also they may induce oxidative damage in your respiratory system that brings on coughing, sneezing, and shortness of breath. Lastly, microplastics hamper the production of hormones which can result in metabolic, development, and reproductive issues.
How Microplastics from Cups Can Impact Your Body
Consider to-go cups for coffee. They are just made of paper, right? These cups are mostly paper, but the lining contains plastic that can leak around 25,000 micron‐sized microplastics. A better option would be to purchase a stainless steel travel mug for your coffee. If you want to purchase coffee on the go, have your travel mug handy so you can pour your beverage in that instead.
What’s the Healthiest Coffee Choice? Go Organic
Buy organic coffee that is free of harmful pesticides! Purchasing coffee in bean form is often cheaper, but mainly, freshly grinding your coffee beans makes your coffee taste better. I prefer dark roast since that makes the coffee less acidic.
My Favorite Organic Coffee Picks
My favorite is Cameron’s Organic French Roast. In recent years, I have become sensitive to caffeine, so I also like Cameron’s Organic Decaf French Roast. The taste is great, and the price is comparable to mainstream brands. This coffee is pesticide-free and the same price as toxic coffee.
Other great options are Kicking Horse Coffee, Grizzly Claw, Dark Roast or Kicking Horse Coffee, Swiss Water Process, Whole Bean Decaf Coffee. This brand is slightly more expensive than Cameron’s, but is still a great price for organic coffee.
In the morning, I will usually make my coffee half caffeinated and half decaf so I get a little boost without feeling jittery. If I drink any coffee in the afternoon, it will be decaf so I won’t have any issues going to sleep.
What Should You Add to Your Coffee? Choose Wisely
Now that you have organic coffee, what should you put in it? I recommend you don’t use any creamers containing high fructose corn syrup and other additives. If you want to sweeten your coffee, use plain sugar or a liquid sweetener like monk fruit. Then add plain creamer. A few years ago, I switched to drinking coffee with only half and half creamer. I also added a dash of cinnamon and vanilla extract. Now, I simply like the taste of strong coffee with only half and half creamer.
Final Thoughts: Is Your Coffee Toxic or Safe?
If you’ve ever wondered is your coffee toxic, now you know the risks and how to avoid them. From harmful pesticides and plastic exposure to microplastics in K-cups and to-go cups, your daily cup of coffee could be doing more harm than good—unless you choose wisely. The good news is, switching to organic, pesticide-free coffee and using non-toxic brewing methods is a simple change that can support your long-term health. Upgrading your creamer and sweetener choices can make a difference too. Small steps add up, especially when it’s something you consume every single day. Want to build more healthy eating habits?
