Today I read a very sad sentence. From the Perfect Health Diet post Around the Web; PaleoFX Edition:
Warning: Dr Clark says that coffee is bad for people with gluten sensitivity, due to cross-reactive antibodies.
Say it isn’t so. This is the video of Dr. Clark explaining how people with gluten issues, like myself, could also have issues with the protein in coffee.
(original video removed. Updated video here)
From the video:
Ten percent of coffee is a protein that cross-reacts with gluten antibodies.
I like coffee. I like coffee a lot. Some might say that INeedCoffee. It would really suck if the protein in coffee was negatively impacting my health. There are strong similarities between the headaches I get after gluten exposure and my late night sinus headaches.
The important take away I got from the video was that the problem was with the protein, not the caffeine. I would assume this means the problem exists with decaf coffee as well. Why is that important? Two reasons come to mind.
- During my 2 week test with no coffee in September 2011, I drank decaf coffee.
- To test for a sensitivity to a protein requires a 30 day elimination. Like I did for casein and gluten independently.
This means I need to redo my coffee detox test. Only this time it needs to go a full 30 days and I can’t drink any decaf. The goods news is that I can drink all the tea I want. Dr. Clark responded to a question regarding tea in the comments of the video.
Green Teas is not? a cross reactor…caffeine is not the cross reacting compound. It’s the protein in Coffee…
Espresso vs Brewed Coffee
Did you know that the nutritional outcome of coffee varies based upon how it is brewed? That is what I learned back in 2009. I shared what I found the article Black Coffee and Espresso – Not Calorie Free.
Digging further into the data I noticed that brewed coffee has 0.3g of protein. Protein has 4 calories per gram. This would give the brewed coffee 1.2 calories. That is some conservative rounding. Espresso is listed with no protein.
I went back to the CalorieKing website and it now reads that espresso has less than 0.1 gram of protein. Brewed coffee has 0.3 grams per 8 oz. Why is this relevant? Over the past few years I have become almost exclusively an espresso drinker. When I do have brewed coffee, I feel worse. I always assumed it was because brewed coffee has more caffeine. However, when I think back to when I had brewed coffee it was always just tastes at Coffee Cuppings or samples from brewing demos. I almost never would sit down with a full mug of regular coffee. If I did, I often would get headaches. Interesting.
Time For Another Test
Only a test will tell me the answer. I’m going to start scaling back on my coffee again in preparation for a full 30 Days Without Coffee experiment. This is going to be my toughest experiment yet.
