I LOVE to drink delicious coffee. Drinking 16oz of coffee each morning with a little half and half and sugar is one of my daily rituals.
Technically coffee is derived from a bean and beans are known to be high in nickel. The original green coffee beans are roasted, where they actually turn brown, anywhere between 200 °C / 392 °F for a light roast to 245 °C / 473 °F for a dark roast. It’s argued when the coffee bean is processed and heated for either a medium or dark roast, the beans are vastly different from their initial state. We probably wouldn’t want to consume other types of beans if they were roasted to these hot temperatures for the same period of time.
Since volcanic soils tend to have more nickel, I drink non-kona coffee, that’s from the rain forest, namely Ethiopia and Guatemala. Personally, I believe some of the nickel in the coffee beans could be roasted away during the coffee roasting process. I don’t have any evidence to support my theory, but I have read that drinking a moderate amount of coffee can reduce your body’s absorption of nickel.
Dietitian Maggie Moon writes in her book The Elimination Diet Workbook (affiliate link) that “Vitamin C, coffee, tea and milk all make it hard for the body to absorb nickel, research shows the amount of nickel absorbed is dampened when nickel was consumed with tea. The exact mechanism is unknown” (pg. 50). Further in her book Moon writes more about nickel and coffee stating “But be aware that tea and coffee tend to have moderate levels of nickel, so it’s good to include them sparingly, perhaps 1 to 2 cups per day” (pg. 173).
Using my mostly plastic Hamilton Beach 12 cup programable coffee maker (affiliate link), and since using it I haven’t had any eczema or skin issues when I drink my daily coffee. I have heard from many others with nickel allergies and nickel food allergies who experienced terrible reactions from the stainless steel reusable filters for some coffee makers. Sometimes I still use a simple plastic clever coffee dripper (affiliate link). which I use with #4 coffee filters, which is a good nickel free option if you don’t want to use a coffee maker.
Do you drink from a stainless steel to-go mug? Beware of hidden nickel in your coffee machine or in your metal to-go mugs. Using a plastic or ceramic to-go mug could improve your nickel allergy symptoms especially if you use it daily. The ceramic mugs I received for Christmas from my spouse who found them for a couple dollars at a Joann’s craft store! The other plastic mugs I’ve found were at grocery stores in their cookware aisle or at National Park gift stores when we travel.
I’d love to hear if you can or cannot handle 1-2 cups of coffee in your diet or what products you use to brew your coffee. Let me know by commenting below.
