2. Cocoa Powder
By the same token, since cocoa powder and chocolate come from the same plant (cacao), cocoa powder (staple of Christmas eves and rainy days) is also unfortunately high in nickel. Pure cocoa powder has a concentration of 9.8 µg/g, according to Principles of Food Chemistry. That’s almost 9 times the nickel content of milk chocolate! If you’re allergic to nickel, you might want to opt for eggnog instead on your next Christmas gathering.
3. Cashews
Cashews, the crunchy, salty, buttery nuts with a characteristic C shape, are packed with vitamins and minerals, as well as antioxidants. They have various health benefits like promotion of weight loss, improving vision, providing iron and copper for red blood cells, and many others. But cashews also contain 5.1 µg/g of nickel, and consuming too much of it might lead to undesirable consequences if you are allergic to nickel. If you’re after the antioxidants of cashew, eat it sparingly, or try other foods with antioxidants like artichokes or cilantro.
