One controversial theory claims that high levels of uric acid increase a person\u2019s likelihood of both gout and genius. Does such a link really exist? Read on as we explore the strange science behind uric acid and what may increase it.<\/p>\n
<\/p>\n
Scientists believe that uric acid can be both pro- and antioxidant, depending on the circumstances. Most of these mechanisms haven\u2019t been explored in humans [R<\/a>, R<\/a>, R<\/a>].<\/p>\n The link between uric acid levels and intelligence, longevity, and neurological or nerve diseases is still unclear.<\/strong><\/p>\n Plus, the majority of human studies covered in this article deal with associations only, which means that a cause-and-effect relationship hasn\u2019t been established.<\/p>\n For example, just because intelligence has been linked with higher uric acid in the body doesn\u2019t mean that increasing uric acid levels will make you smarter. Data are lacking to make such claims.<\/p>\n Also, even if a study did find that high uric acid levels contribute to intelligence, uric acid is highly unlikely to be the only cause. Complex traits like always involve multiple possible factors – including brain chemistry, environment, health status, and genetics – that may vary from one person to another.<\/p>\n In 1904, Havelock Ellis found in his \u201cStudy of British Genius\u201d that there was an unusually high rate of gout among included eminent men. But since gout is associated with higher uric acid (or urate) levels in the blood, Havelock first suggested that uric might have something to do with intelligence (R<\/a>).<\/p>\n Mind you, what made a man \u201ceminent,\u201d let alone a \u201cgenius,\u201d at the time was a matter of debate.<\/p>\n For example, Ellis excluded less popular writers and \u201cvillains.\u201d He said that eminent men are \u201ceither shorter or longer than average,\u201d that \u201csome are shortsighted and stammer,\u201d have \u201cillegible handwriting,\u201d and are \u201cmerry late\u201d (R<\/a>).<\/p>\n More recently, some investigators have examined this relationship, but they stumbled upon a lack of a clear correlation.<\/p>\n Small studies from the 70s and 80s found only a slight correlation between IQ and uric acid. There seemed to be a stronger correlation between uric acid and scholastic achievement after controlling for IQ, but even this remained elusive (R<\/a>, R<\/a>).<\/p>\n Uric acid is chemically somewhat similar chemical to caffeine<\/a>, since it is a \u201cpurine.\u201d Their structural similarity is thought to underlie some antioxidant effects. Based on this, one unverified theory also suggests that uric acid may act as a natural stimulant (R<\/a>).<\/p>\n Uric acid levels appear to correlate with longevity<\/a> in monkeys and animals. Scientists say this might be because of urate\u2019s antioxidant properties. Still, no such association has been explored in humans (R<\/a>).<\/p>\n Some small studies have suggested a link between low uric acid and certain brain diseases, but large-scale studies haven\u2019t confirmed this connection.<\/p>\n For example, low uric acid levels have been associated with Multiple Sclerosis<\/a> (MS). One small study of 11 people suggested that correcting uric acid levels may improve MS symptoms and reduce Th1<\/a> immune dominance<\/a>, but this hasn\u2019t been confirmed in large trials (R<\/a>).<\/p>\n Lower blood values have also been associated with the following disorders in limited studies:<\/p>\n But remember, these studies dealt with associations only, which means that a cause-and-effect relationship hasn\u2019t been established.<\/p>\n As an antioxidant, urate is hypothesized to provide up to 60% of the antioxidant capacity in human blood (R<\/a>).<\/p>\n On the other hand, some researchers consider that uric acid may increase the Th17<\/a> immune response<\/a> in inflammation (IL-1b<\/a>, IL-1<\/a>8<\/a>) (R<\/a>).<\/p>\n Thus, low uric acid levels are proposed to contribute to oxidative stress<\/a> and high levels to lead to inflammation, gout, and kidney stones. This has yet to be confirmed in large human studies (R<\/a>).<\/p>\n It\u2019s important to speak with your doctor if your uric acid levels are low. Your doctor should diagnose and treat any underlying conditions causing your abnormal levels.<\/strong><\/p>\n Also, raising uric acid levels is usually detrimental. High uric acid levels signal gout, kidney problems, and other health issues. For example, a meat-heavy diet\u2013high in purines\u2013increases uric acid levels and causes flare-ups in people with gout [R<\/a>].<\/p>\n On the other hand, people with low uric acid levels due to Wilson\u2019s disease should follow a special low-copper diet [R<\/a>].<\/p>\n Therefore, all dietary and lifestyle interventions should be based on the cause of your abnormal uric acid levels and your overall health.<\/p>\n With this in mind, you may try the complementary approaches listed below if you and your doctor determine that they could be appropriate. Remember that none of them should ever be done in place of what your doctor recommends or prescribes.<\/p>\n Zinc<\/strong><\/a> may normalize uric acid levels in people with Wilson\u2019s disease who are deficient [R<\/a>].<\/p>\n Animal products<\/strong> like meat increase levels in general. This is usually considered detrimental, since a diet high in animal products (and purines) has only been studied in people with gout who have high uric acid levels. It\u2019s unknown how a diet high in meat and animal products impacts low uric acid levels, but this will always depend on the underlying cause [R<\/a>].<\/p>\n Dairy and maybe calcium<\/a> lower uric acid levels. Some authors think that this might explain why vegans<\/strong> have higher levels than omnivores. Soy might also increase urate levels (R<\/a>).<\/p>\n Uric acid levels rise after strenuous exercise<\/strong>, potentially a result of purine nucleotide degradation during conditions of high energy usage. Intense exercise is not recommended to most people, since it puts too much stress on the body. Regular, moderate exercise supports overall health [R<\/a>].<\/p>\n Also, alcoholic drinks (especially beer) increase uric acid levels and worsen symptoms in people with gout. But since alcohol can have wide-ranging harmful health consequences, doctors will recommend restricting or completely avoiding alcohol in the case of many diseases, including those linked with low uric acid levels [R<\/a>].<\/p>\n For example, people with Wilson\u2019s disease who have high copper and low uric acid levels are advised to avoid alcohol. This is because alcohol can damage the liver, which is already vulnerable due to excess copper in the body [R<\/a>].<\/p>\nIntelligence<\/span><\/h3>\n
