More bull… from Bulletproof

Ugh. Why won’t Bulletproof bullshit just go away?? Earlier this week I saw this article about the new Bulletproof “Fatwater” which supposedly is more hydrating than regular old water because of the oil in the water. According to the creator, Asprey, “People have been talking for many years about how our bodies are dehydrated and how we need even more water in the body and not just more water in the mouth. This is our contribution to help people solve that problem.” Who’s been talking about this for years? Why, after water sustaining life on earth for at least 3.5 billion years is it suddenly not good enough? No, this is a solution to a problem that doesn’t exist. This is just an opportunity for Asprey and his company to make more money off unwitting people who buy into his self-proclaimed status as a biohacker.

As if that ridiculous product didn’t get me riled up enough, then my friend sent me a link to this Bulletproof article about how beans are deadly. Which, as it turns out, is several years old, and one of many in the paleo world proclaiming beans, and other lectin containing foods to be deadly. Oh crap, because I’ve unwittingly been eating beans and legumes for about 37 years. Who knew that I was committing suicide all this time? I guess my days are numbered.

What is lectin you might be asking? It’s a protein found in many foods, but at the highest levels in beans, legumes, and grains. And, it’s true, it can make you quite illBUT cooking, or sprouting, the foods that contain lectin destroys most, if not all of it (1, 2). So, unless you’re chowing down on raw kidney beans, it’s a non-issue.

There also seems to be some confusion in the article, and the comments (yes, I know, I broke the cardinal rule and read them), about lectin and the difficulty that people have digesting beans. Lectin is not why you get gas after eating beans. It’s actually the oligosaccharides raffinose and stachyose that are indigestible by humans that cause some people to become gassy after eating beans. This is not a sign that beans are toxic. It’s actually a good thing because the bacteria in your intestine are happily feeding away on these complexes, and we are becoming increasingly aware of the importance of the human microbiome on many aspects of health.

In defense of beans, as they seem to bear the brunt of this anti-lectin movement; they are affordable sources of protein, fibre, calcium, and magnesium, among other nutrients. You can buy many cans of beans (30 at $0.99 each) for the $29.95 price of 160 ml of fatty water.

  1. Amen to this! Seriously why won’t the bulletproof thing just go away! Now we’re adding oil to our water? Oy vey.

  2. Love your response! Beans are the bomb. I’m still trying to get my head around the term “fatty water” and how that’s ever going to appeal to people…

  3. Whenever people talk about “toxins”, it always frustrates me that no distinction is made between acute toxins and persistent/environmental toxins. This leads to people thinking that simple toxins, easily metabolized, (like lectin), can build up with chronic exposure like mercury or some carcinogens. Alcohol is a toxin, but that doesn’t mean it has chronic exposure risks (besides being hard on the liver).
