One of the toughest parts of my job as a nutrition coach is helping people to quit coffee. This recommendation is never well received! It’s harder than giving up sugar or alcohol for most people. Trust me, I can relate. I clung fiercely to my morning cup of coffee for a long time, even though I didn’t like feeling so addicted, I was uneasy about the chemicals and pesticides in coffee, and I wanted to create my own energy throughout the day instead of relying on my morning fix. What’s the problem with coffee? Coffee is very acidic and dehydrating. Coffee taxes your adrenal glands, as well as your liver and kidneys. And caffeine seriously disrupts your sleep. Coffee has a half-life of 7 hours, so it stays in your system for a long time.
