Parkinson’s illness, the second most typical neurodegenerative dysfunction after Alzheimer’s, is characterised by a slowness of motion, rigidity, tremor, and stooping posture, all of which worsen over time. Non-movement signs akin to cognitive impairment and sleep, odor, and temper disturbances happen because the illness spreads to different areas of the mind. The reason for Parkinson’s is probably “one of many necessary questions posed by the neurobiology [science] of ageing.” For instance, why is the consumption of dairy merchandise related to elevated threat of Parkinson’s? Maybe as a result of they contribute to our publicity to pesticides and different neurotoxins like dieldrin, which continues to be discovered within the autopsied brains of Parkinson’s victims. Though dieldrin was banned many years in the past, it lingers within the atmosphere and we “proceed to be uncovered to the pesticide by contaminated dairy and meats…”
The reason for Parkinson’s “is unlikely to be resulting from milk compounds akin to calcium, vitamin D, complete fats, or complete protein as these compounds will not be related to [the disease] when derived from different sources.” Nonetheless, it might be lactose, the milk sugar, maybe accounting for the elevated related threat of loss of life and bone fractures, in addition to Parkinson’s. Earlier onset of Huntington’s illness has additionally been recognized. There may be, nonetheless, a 3rd chance.
As I talk about in my video Parkinson’s Illness and the Uric Acid Candy Spot, milk lowers uric acid ranges, and uric acid could also be protecting towards Huntington’s and in addition gradual the decline brought on by Parkinson’s. Extra importantly, it might decrease the danger of getting Parkinson’s within the first place. Why? Maybe as a result of uric acid is a vital antioxidant within the mind, one thing we’ve identified for greater than 30 years. We are able to display uric acid’s significance immediately on human nerve cells in a petri dish. When the pesticide rotenone is added, oxidative stress goes up. Add the pro-oxidant homocysteine, and it goes up much more. However, when uric acid is added, it fully suppresses the oxidative stress brought on by the pesticide.
Consuming milk, nonetheless, has a uric acid-lowering impact. Within the paper making this assertion, a research they cited was “A cute impact of milk on serum urate concentrations,” however that was only a cute typo—they meant Acute impact. Certainly, drink cow’s milk, and, inside hours, uric acid ranges drop 10 %. Drink soymilk, and, inside hours, they go up 10 %. Now, for gout, a painful arthritic illness brought on by an excessive amount of uric acid, the uric acid-lowering impact of dairy is an efficient factor—however uric acid is “a double-edged sword.”
If our uric acid ranges are too excessive, we are able to get gout, however, in the event that they’re too low, it might enhance our threat of neurodegenerative illnesses, akin to Alzheimer’s, Huntington’s, Parkinson’s, and a number of sclerosis.
Incidence charges of gouty arthritis over 5 years point out that if our uric acid is over 10.zero mg/dl, we now have a 30 % probability of struggling an assault of gout throughout the subsequent 5 years. Nonetheless, at ranges underneath 7.zero mg/dl, our threat is lower than 1 %, so it’d make sense to have ranges as excessive as attainable with out going over 7.zero to guard the mind with out risking our joints. However having extreme uric acid within the blood places extra than simply our joints in jeopardy. Sure, having ranges which might be too low might enhance our threat of MS, Parkinson’s, Alzheimer’s, and even most cancers, however having ranges which might be too excessive might enhance our threat of gout, kidney illness, and coronary heart illness.
In actual fact, having a uric acid stage over 7.zero mg/dl isn’t solely related to an elevated threat of gout, but additionally an elevated threat of dying from all causes. Nonetheless, having a low uric acid stage might also shorten our lifespan by rising mortality. Excessive uric acid ranges are related to elevated threat of loss of life from coronary heart illness, however low uric acid ranges are related to elevated threat of deadly stroke. So, maintaining uric acid at optimum ranges, the candy spot between 5.zero and seven.zero mg/dl, might shield the mind in additional methods than one.
If we measure the uric acid ranges in sufferers with Parkinson’s, they arrive in round four.6 mg/dl, which can assist clarify why dairy consumption might enhance threat for Parkinson’s since milk pushes down uric acid ranges. Dairy consumption might also clarify the variations in uric acid ranges amongst meat-eaters, vegetarians, and vegans. Within the graph in my video, you possibly can see that vegan males have considerably larger uric acid ranges at 5.7 mg/dl than vegetarians, presumably as a result of vegans don’t drink milk, and people who each eat meat and devour milk fall between the vegans and vegetarians.

Uric acid as an antioxidant? I’ve touched on that earlier than in Miocene Meteorites and Uric Acid.
If uric acid ranges are too excessive contemplate slicing down on Flesh and Fructose and consuming cherries. (See Gout Remedy with a Cherry on Prime and Treating Gout with Cherry Juice for extra info.) Additionally, take a look at Stopping Gout Assaults with Weight loss plan.
