I'm the guy who made this coffee. In my opinion, yes, alfatoxins are dangerous for you, and you should drink coffee which doesn't have them. Most coffee gives me awful symptoms, ones so bad I quit coffee for 5 years before I figured it out. Now I only drink this coffee, because it gives me no symptoms, and I am selling it because I believe it is better for others too. My opinion is that
There are toxins (specifically biogenic amines and mycotoxins) present in coffee at levels high enough to affect how you feel.
Am I saying coffee will kill you? Nope. But bad coffee slows you down - a lot - and low toxin coffee speeds you up - a lot.
To back this opinion, I am currently conducting an IRB-approved study, with Stanford University's assistance, to test the mental performance of people on my Upgraded Coffee vs Starbuck's dark roast. I can also invite you to test the toxin-free coffee for yourself, by purchasing it from me or from other sources (I wrote a blog post "How to find high performance coffee in your city", google it).
My other sources for my opinion are
- This study. It shows detectable aflatoxin in 85 of 127 samples. Some (many) were below the legal limit, but the problem is that the legal limit is not the safe limit, it's the economically feasible one.
- This conference talk. It says that coffee can contribute up to 25% of your daily "safe" (not by my standards) dose of the OTA toxin.
- If you google "coffee mycotoxin" you can find many other studies which have shown the presence of mycotoxin in coffee.
Aaronut's answer suggests that I am not qualified to judge whether coffee with alfatoxins is dangerous. I feel that his "The author section" is an example of "attacking the messenger", which is a poor tactic. Here are my credentials:
- I'm a very successful Silicon Valley exec with enough money that I don't need to con people at all.
- I run an anti-aging group that brings world-class experts in every month.
- My wife is an MD and co-author of my book on nutrition for pregnant women (currently in publishing)
- I've lectured internationally on human performance
- 100 000 people a month read my blog
