Higher blood and urine ranges of uric acid may cause gout (painful uric acid crystal deposition in joints) and kidney illness. Extra just lately, uric acid has additionally been related to elevated danger for metabolic syndrome, kind 2 diabetes, heart problems, kidney and liver illness even within the absence of gout assaults, i.e., “asymptomatic hyperuricemia” or asymptomatic will increase in blood ranges of uric acid. Standard “remedies” contain lowering the dietary consumption of purines, i.e., the genetic (DNA and RNA) materials current in animal merchandise, and prescribed drugs that block the enzyme, xanthine oxidase, that yields uric acid. As in so many different circumstances, the standard options deal with “downstream” phenomena however fail to handle the precise trigger—not food plan, however disruptions of bowel flora composition with lack of microbial species which are vigorous in metabolizing uric acid, thereby lowering blood and urine ranges. This science has been unfolding for in regards to the previous decade, nevertheless it has just lately galloped ahead with a flood of latest observations which are yielding therapeutic prospects in managing uric acid. (It additionally addresses a basic flaw in typical pondering: Why would people, genetically-adapted over three million years to consuming animal merchandise corresponding to meats, organs, and seafood, develop an intolerance to them? The issue just isn’t animal merchandise; it’s the capability to metabolize elements corresponding to uric acid, disrupted by shifts in gastrointestinal (G) microbiome composition as a result of trendy life and maybe worsened by a nutrient- and polyphenol-poor trendy food plan.)
Individuals with gout and hyperuricemia have been proven to have 1) disrupted gastrointestinal microbiome composition with elevated Proteobacteria (fecal species) and mucin-degraders corresponding to Bacteroides caccae, 2) elevated intestinal permeability, and three) elevated endotoxemia, all of which additional provides to irritation, insulin resistance, and susceptibility to heart problems. You’ll be able to respect that gout and hyperuricemia will not be nearly uric acid, however a constellation of phenomena, a lot of which might be backtracked to a disrupted GI microbiome.
The checklist of gastrointestinal microbes that metabolize uric acid in numerous methods is rising quickly, largely Lactobacillus species which have developed to be environment friendly metabolizers of purines and different genetic materials. Among the many species/strains which were related to diminished blood and urinary ranges of uric acid embrace:
- Lactobacillus brevis DSM9218
- Lactobacillus plantarum WCFS1
- Lactobacillus paracasei S12
- Limosilactobacillus fermentum GR-3
- Lacticaseibacillus paracasei MJM60396
- Ligillactobacillus salivarius CECT 30632
A human examine of the final microbe listed, L. salivarius CECT 30632 at a every day dose of 1 billion CFUs per day for six months, demonstrated a marked discount in gout episodes, reliance on gout medicine, and diminished blood ranges of uric acid in comparison with placebo.
Along with over proliferation of fecal microbes and mucin-degrading species, lack of essential butyrate-producing species, Faecalibacterium prausnitzii and Bifidobacteria species, has additionally been documented. Though F. prausnitzii and Bifidobacteria species don’t themselves metabolize uric acid, they by some means assist people who do. Recall that prebiotic fibers corresponding to inulin/FOS trigger a “bloom” in these species, that will additionally add additional benefit. Additional, microbial metabolism of purines and different genetic materials is considerably elevated when glucose (sugar) is much less obtainable; in different phrases, a scenario wherein insulin resistance and blood glucose are introduced below management could additional improve the microbiome’s capability to rid your physique of purines and thereby uric acid.
In fact, you can attempt to acquire and ferment a few of these species, as we do with our L. reuteri and L. gasseri yogurts to acquire excessive bacterial counts to make sure significant organic results corresponding to eradication of SIBO, smoother pores and skin, elevated libido, diminished intestinal permeability and decreased endotoxemia. However, as you may respect, it turns into impractical to ferment every species we need to colonize our GI tracts. Apparently, nearly all of species that metabolize purines and thereby scale back uric acid come from fermented meals corresponding to sauerkraut, pickles, and kimchi. Maybe in future we will acquire a number of of these microbes corresponding to L. salivarius CECT 30632 that you can ferment as yogurt to amplify uric acid-reducing results. There may be sometimes a a number of 12 months lag going from laboratory statement to industrial availability, so these microbial strains will not be but obtainable. Keep tuned.
By the way in which, uric acid just isn’t the one issue that’s proving to be a metabolic consequence of a disrupted gastrointestinal microbiome. Add oxalates, homocysteine, vitamin B12 deficiency, folate deficiency and various different conditions which are yielding to insights into the microbiome that, like uric acid, ought to trigger us to rethink all we thought we knew about these phenomena.
