Can Mushrooms Raise Blood Glucose?

My blood glucose has been very good for the most part since starting this blog. I’ve had the odd spike, but overall my waking glucose has been between 6.2 and 7.6 mmol/L. However, I had a very surprising spike the other day after eating steak with baked mushrooms and asparagus for dinner. I woke up with a reading of 9.4 mmol/L. What gives?

Experience and logic tells me it definitely wasn’t the steak. Moreover, I have never had a problem with asparagus. So this leads to mushrooms. I have had an inkling in the past that they might have been having a slightly negative effect on my blood. Is there any evidence linking these delicious fungi with elevated glucose?

The answer seems broadly no. Most websites state that mushrooms are diabetic friendly. Some websites even claim that mushrooms can help with blood glucose levels. Whilst others tout the health benefits of Maitake and Reishi mushrooms from the Orient.

So where did the blood spike come from? Don’t know. I wasn’t very active that day, and I did eat a lot of mushrooms with my steak. Even if something is low-carb, too much of it will lead to higher glucose levels. Maybe I was fighting off an a-symptomatic infection? If I have more blood spikes after eating mushrooms, it may be time for a new experiment.

In any case, the research I did today is not a total loss. I can start looking into the supposed benefits of Maitake and Reishi Mushrooms!
