Is Mold In Your Food Making You Sick?

Guest Post from Dave Asprey, Bulletproof CEO


Last week, we shared some key pointers on how to get better sleep from our good friend, Dave Asprey. Dave knows a thing or two about food too, so this week, he’s helping us determine whether the food we eat (or the mold in it) is actually making us sick! We hope you enjoy this second post in our two-part Bulletproof series! Happy holidays to all of you from all of us here at the Irlen Institute.

Can’t Figure Out What’s Making You Sick? It Could Be Mold In Your Food

By: Dave Asprey

Are you doing everything the health “experts” recommend and still struggling to feel good, lose weight, and keep your energy up? This could be because of a hidden problem no one talks about. If you can’t figure out what’s making you sick, it’s probably the mold in your food.

The damaging impact of mold

Both as a kid and later as an adult I unknowingly lived in several moldy houses.  Because of the repeat exposure, my immune system is more sensitive than the average person’s to mold in my environment or in my food. On a business trip to the UK, I once went down into the Tube and noticed the dank air. By the time I reached the end of the passenger tunnel and got on the train, I started to feel like I was hung over and even had some visual hallucinations.  That’s how sensitive I am to mold as a result of repeated exposure. Right after that experience in the tube, I had profound cravings for sugar and fat, and it took almost a full day before it felt like my brain had turned back on.

This experience enabled me to help clients identify why they have seemingly inexplicable declines in mental and physical performance and led me to learn more about the biochemistry of mold exposure both in sensitive people like me (about 28% of the population), and in the rest of us. If you’re not feeling amazing, there is always a reason!

Mold in our coffee

I’ve known for a long time that being in a moldy environment was awful for cognitive performance, but it was coffee that first turned me on to mold toxins in food. Coffee has been a great passion of mine since I first discovered that it improved my grades in college.

Imagine my dismay a few years later when I began to notice that coffee wasn’t serving me. I’d drink it, get a boost, and then start to feel fatigued and cranky, like I needed more coffee. I was constantly upping my dose, which sometimes led to headaches.  Wanting to rid myself of these symptoms, I gave up the black brew for five long, dark years

One day, coffee’s siren call was strong enough to compel me to have “just one cup,” and I felt amazing. No crash. No jitters. No headache. Just pure focus, the way I remembered. I was elated that coffee appeared to no longer be a problem for me.

I had another cup of coffee though, and this time I felt anxious and weak, and later my joints hurt – totally not Bulletproof. But this time the biohacker in me realized that the key variable wasn’t me; it was the coffee! I dug into the biochemistry of coffee and the agricultural and economic research to discover that all coffee is not the same, and that coffee often carries naturally occurring mold toxins. It turned out that my reaction to certain coffees had nothing to do with the coffee; it was a reaction to the mold on the coffee.

Mold in our food

Mold toxins aren’t found only in coffee; they are commonly found in all sorts of food crops.  Mold grows on crops and secretes toxins long before the food is harvested, making this a widespread problem that is not news in the agricultural community. Besides coffee, the main sources of mold toxins in your diet are wheat, corn, and other grains, but peanuts, fruit, chocolate, and wine are often tainted with mold toxins, too.

Mold toxins accumulate in the milk from cows that ate contaminated grains[i].  In fact, grain-fed animal products often pose a higher mold toxin risk than the grains themselves because the mold toxin controls on animal feed are much more lenient than the controls on grains in our human food supply, and corn-fed and grain-fed animals accumulate mold toxins in their fat. In fact, one of the unacknowledged reasons low carb diets work is that when you eliminate grains, you end up with a lower level of mold toxins in your food. Not only are you what you eat; you are what your food ate!

Mold toxins are sneaky because there is no way to tell for sure whether or not they are in a certain batch of food. For instance, one bag of nuts maybe perfectly clean, but another bag from a different batch may contain levels of mold toxins that will make you weak – even though you can’t taste them.  Our big brains make us the most susceptible mammal on earth to the effects of mold toxins, and it’s important to know that mold toxins may be causing your unexplained fatigue or making your focus waiver.

Cutting out mold

Mold is a common problem in my high performance clients and eliminating high-risk foods usually helps with brain focus first. This is why the Bulletproof Diet goes far beyond a regular Paleo or low toxin diet by drastically reducing foods known to be commonly contaminated with mold toxins and acknowledging that they impact how you function long before they make you outright ill.

The Bulletproof diet gives you a clear guide for cutting toxins out of your diet, including mold. For example, with food it’s best to avoid gluten grains and most dairy products and replacing them with high-quality proteins, fats, and vegetables. For coffee, one way you can avoid mold is by buying high-quality beans from a single source.

The Bulletproof Diet is not an all or nothing approach; it’s a simple road map that will help you make better choices so you can eat more of the foods that move your health and performance in the right direction and fewer of the ones that don’t support your goals. With this advice, you’ll cut out the hidden toxins like mold that are making you sick.
