National Coffee Day: A Blessing or A Curse?


In honor of National Coffee Day many businesses are giving away free cups of Joe (some are even throwing in a doughnut). Wait! Before you run to your nearest coffee giveaway you may want to consider what that cup is actually doing to your body. That may have just put you on the defense because, let’s face it, no one wants to give up their coffee, myself included, but as someone who has a thyroid problem and speaking to others that are trying to address theirs, we may want to know what our dearly beloved caffeine can do to us.

Let’s talk about that wonderfully smelling and tasting liquid that we wake up to everyday. Coffee and caffeine are actually two different things. Caffeine is just one compound found in coffee (it contains hundreds of other compounds, as well). This compound works as a stimulant of the central nervous system. Coffee on the other hand is simply a drink made from bean-like seeds of a tropical shrub.

So where does the problem lie? Unfortunately, it is the same thing that perks us up in the morning: caffeine.

Gerard Derby wrote a book entitled, Coffee and Health in which he stated when conducting a study very high doses of caffeine caused the thyroid gland to enlarge in rats. Other studies have pointed to caffeine causing stress to the thyroid and like everything else, long periods of stress can lead to a crash.

Also, if you already experience hyperthyroid symptoms such as digestive issues, heart palpitations, insomnia, and nervousness, it may be a good idea to cut back on the amount of caffeine you ingest because these are all side-effects of caffeine, as well.

Hyperthyroidism has another symptom that may not be as well-known and that is calcium deficiency. We all know that low levels of calcium can lead to bone deterioration/osteoporosis. Caffeine actually causes the body to excrete calcium through urine. A study in the JAMA stated, “There was a significant association between caffeinated coffee and decreasing bone mineral density at both the hip and spine…”

I know, I know. You may not be entirely convinced to give up your caffeine just yet, but it may be a good idea to begin cutting back. Below is a list of how much caffeine is in various types of coffee. It may come in handy when deciding to cut back on your intake.

  • 8oz of brewed coffee contains between 95-200mg of caffeine
  • 1oz of espresso contains between 47-75mg of caffeine
  • 8oz of instant coffee contains between 27-173mg of caffeine
  • 8oz Latte or Mocha contains between 63-175mg of caffeine

Just think about how much you are actually consuming if you are having more than one caffeinated drink a day and that doesn’t even factor in soda, tea, etc. While it may be hard to skip the caffeine in the morning, it may be in our best interest and our thyroid’s best interest, as well.

Do you have any decaf or low-caffeinated, thyroid-friendly drinks that you find enjoyable? Share them with us below!
