    The Science of IQ Bars

    6 Brain Nutrients
    IQ Bars are meticulously formulated around six nutrients shown to support sustained cognitive energy, performance, and health. They include Lion's Mane, MCTs, omega-3s, flavonoids, vitamin-E, and choline. Read up on the wonders of each of them below!

    • Lion's Mane
      Used in Chinese medicine for millennia, the Lion's Mane mushroom is widely championed for its potential brain benefits. It's perhaps best known for its demonstrated ability to boost nerve growth factor (NGF) across a host of animal studies. NGF promotes the generation of new neurons, the growth, maintenance, and survival of existing neurons, and the reversal of injury-induced nerve damage. In vitro research has shown Lion's Mane to also promote neurite outgrowth, a process by which neurons create more expansive cellular connections.
    • MCTs
      Medium Chain Triglycerides (MCTs) are a powerful alternative brain energy source to carbohydrates and longer-chain saturated fats. When most fats are digested, they are broken down in the intestines, circulated in the bloodstream, and finally metabolized in the liver. In contrast, MCTs are sent directly from the small intestine to the liver where they are broken down quickly and easily into compounds called ketones. While ketones provide near-instant energy to the brain in much the same way that blood sugar from carbohydrates does, they are released in a far more sustainable, crash-free stream.
    • Omega-3s
      If there was a brain nutrient rockstar, it would be omega-3 fatty acids. On top of energizing the brain, omega-3s are a primary structural component of the organ itself, representing 8% of its total weight, and the majority of the weight of substructures like neuronal plasma membranes. Moreover, greater consumption of these acids has been found to correlate with higher gray matter volume in critical components of the brain - especially in its memory center, the hippocampus. A major driver of this correlation is omega-3's apparent capacity to include creation of brain-derived neurotrophic factor (BDNF), a protein that supports new neuron formation. Despite these benefits, 70% of Americans are omega-3 deficient.
    • Flavonoids
      Flavonoids are one of the reasons people feel "sharp" after consuming colorful fruits and vegetables. When ingested, these compounds signal the body to prioritize cognitive resources and functionality. For instance, flavonoids have been shown to drive greater blood flow to the brain. They also appear to increase density of (i.e., strengthen) synaptic connections between neurons, and to activate new inter-neuron improved cognition. Across human studies measuring processing speed, executive function, working memory, and learning, flavonoids have been shown to cause significant improvements.
    • Vitamin E
      Vitamin E is a powerful antioxidant that serves a critical role in protecting the brain over time. Neuronal cell membranes are comprised of fats and cholesterol that are highly susceptible to oxidation and inflammation caused by free radicals. Vitamin E embeds itself into these cell membranes and effectively shields them against free radicals, thus preventing chain reactions of structural damage. Despite vitamin E's capacity to drastically slow the cognitive aging process, well over 90% of adults in America do not consume adequate quantities of the nutrient.

    • Choline
      Choline - considered an essential nutrient by the Institute of Medicine - is perhaps the most underappreciated brain compound in existence. First and foremost, we need it to properly form brain cells. choline is a critical component of our neurons' membranes, and without it, our cells' structural integrity breaks down. Additionally, choline metabolizes into key messenger chemicals like acetylcholine, which our brains require to regulate muscle control, memory, and mood. While the body can produce choline in the liver, it cannot generate enough to meet our needs. Thus, without dietary choline consumption, our brain structure and function degrades.

    High Fat, Low Carb Keto Bar
    The vast majority of bars are high in net carbohydrates (carbs that are digested into blood sugar) and low in fat. At IQ Bar, they've flipped this convention on its head. IQ Bar's bars contain ~10g of healthy fats and just 4g of net carbs, (making them fully ketogenic, or "keto").

    • Brain Health
      Not only is the brain the fattiest organ in the body (at 70% fat), but vitamins critical to brain health - like A, D, E and K - cannot be absorbed without dietary fat. Thus, it's no surprise that a high-fat diet correlates with cognitive health benefits. In their Functional Nutrients section, they detail benefits of specific fats like omega-3s. In addition, though, numerous studies have uncovered positive long-term effects of high-fat diets in general. For instance, a seminal 1998 post-mortem study found that control patients had vastly greater fat content in their cerebrospinal fluid relative to Alzheimer's patients. A more recent, 2012 study found that older people whose diets were highest in fats were 42% less likely to develop mild cognitive impairment (MCI), a condition widely considered to be a precursor of Alzheimer's.

    • Sustained Energy
      Fat has served as a primary bodily and cognitive energy source for over 99% of humans' two-and-a-half million year evolution. Our hunter-gatherer ancestors thrived on a diet consisting of roughly 75% fat, and it wasn't until 10,000 years ago - a blip in our species' history - that modern agriculture introduced fat-displacing foods like grains to the human diet. Moreover, it wasn't until the 1970s, when the US Senate Committee on Nutrition and Human Needs began pushing carbohydrates (largely through their "Dietary Goals for the United States"), that the low-fat diet gained serious traction in America. Thus, from an evolutionary standpoint, it's fair to say we are still "pre-programmed" to run on fat, and there's quite a bit of research to support that position.
    • Preferred Fuel
      Some in the health, nutrition, and fitness spaces have deemed carbohydrates to be the human body and brain's preferred source of fuel. Here, they'll address two arguments commonly made by those who assert this position, and provide IQ Bar's response to these arguments:
      • Pro-Carb Argument #1: Our body metabolizes carbohydrates before fats. Thus, carbohydrates must be our body's preferred fuel source.
        IQ Bar's Take: If this logic was valid, our bodies' truly preferred energy source would be alcohol. After all, when we consume alcohol with food, our body metabolizes the alcohol before any other energy source - carbohydrates included. Of course, we all know alcohol is not a desirable energy source, and has numerous deleterious health impacts when consumed at volume. Moreover, a primary reason our body burns carbs before fat is our need to keep blood glucose levels from becoming poisonously high after a meal. The point here is that they at IQ Bar feel the moniker of "preferred energy source" should not be defined by speed of metabolism, but rather by factors such as how dense, clean-burning, and efficiently stored the energy source is. And, in all of these categories, fat is the clear front-runner.
      • Pro-Carb Argument #2: The brain runs almost exclusively on glucose, and cannot use fatty acids as fuel. Thus, carbohydrates must be our brain's preferred fuel source.
        IQ Bar's Take: Our brain does, in fact, run almost exclusively on glucose when we consume a high-carb diet, and it is true that fatty acids cannot be burned as brain fuel, as they cannot pass the blood-brain barrier. However, when glucose and its stored form glycogen are low, the liver readily converts fatty acids into ketone bodies, which can displace glucose as a primary (and arguably more efficient) source of brain fuel. Furthermore, when medium-chain triglycerides (MCT's) are consumed, they are converted by the liver into meaningful quantities of brain-fueling ketones regardless of carbohydrate and glycogen levels. Some brain cells do require glucose-based energy, though this does not have to come from carbs - it can be generated by breaking down proteins and other compounds via gluconeogenesis.
    • Eat Fat, Be Thin
      Unfortunately, when most people think of the word "fat", images of obesity are conjured. Yet consuming a high-fat diet has actually been shown to correlate with weight-loss, not gain. Numerous studies have shown that a high-fat diet results in far greater weight loss than a low-fat diet. The true driver of fat accumulation and retention appears to be the carbohydrate. Of course this is by no means a novel realization. Hugely popular modern weight-loss regimens like the Atkins, Paleo, Whole-30, and ketogenic diets are all predicated on the same principle: cut the carbs. So what is it about carbohydrates that cause us to get fat?

      Gluten, Dairy, Soy-Free Bar
      IQ Bar excludes gluten, dairy, and soy from IQ Bars for two reasons. First, they want people with allergies to these substances to enjoy their products. Second, compounds in substances have been linked with negative brain and body health outcomes. IQ Bar recognizes these links are still actively debated, but will always err on the side of caution!

      • Gluten Free
        Evidence linking chronic inflammation to cognitive dysfunction, depression, dementia, and other negative brain conditions is mounting. Thus, it stands to reason that consumption of compounds that incite inflammation put us at risk. Literature suggests that gluten - a sticky protein that entered the human diet just 10,000 years ago - is one such compound for those with sensitivity to it. A landmark 2006 study identified notable overlap between patients with celiac disease (severe gluten sensitivity) and progressive cognitive decline. The study concluded "a possible association exists between progressive cognitive impairment and celiac disease, given the temporal relationship and the relatively high frequency of ataxia and peripheral neuropathy, more commonly associated with celiac disease."
      • Dairy Free
        Like grains, animal dairy was a recent addition to the human diet, entering ~7,500 years ago. And, while health implications of dairy are debated, much of the scientific community takes issue with a protein similar to gluten that manifested in dairy just several thousand years ago: A1 beta casein. The first knock on this protein is that it breaks down into opiate-like compounds called casomorphins that correlate with inflammation when those with sensitivity digest it. For instance, a 2014 study demonstrated increased levels of the inflammatory biomarker calprotectin in a subset of participants who consumed A1 beta casein. Far more research on casomorphins' inflammatory effects has been conducted on rats and mice, with several studies linking A1 beta casein to the inflammatory biomarker myeloperoxidase.
      • Soy Free
        Soybeans were domesticated by Chinese farmers just several thousand years ago, and a staggering 90+% of soy grown in the US is genetically modified from its original structure. Furthermore, while it is true that certain East Asian societies with long-living populations consume large quantities of soy (a fact the soy industry readily trumpets), the forms of soy these populations consume - organic fermented miso, natto, and tempeh - have markedly different nutritional profiles than the soy most frequently consumed by Americans. For one, the unfermented soy Americans consume is far higher in phytates, compounds that bind to brain-critical minerals like zinc, iron, and magnesium and make them unavailable for absorption in the human gut.
