Sugar Industry Funds Inconclusive CDC Investigation Into Sugar Industry Deaths

7

From Nicaragua to Miami, cases of chronic kidney disease of unknown origin (CKDu) share a common setting: sites where agricultural work takes place in severe heat. Independent research on the cause of CKDu points to chemicals used in sugarcane agriculture, the physiological response to intensive work in the heat, and the sugary beverages commonly consumed by laborers. But researchers receiving millions in funds from the Centers for Disease Control and Prevention, the National Institutes of Health, and the Central American sugar industry have failed to discover the disease’s cause—or investigate some of the leading suspects.

Years of (industry-funded) research into the effects of sugar and the sugar-plantation environment on CKD yields a 'we can't be sure of the cause' but I can assure you the same academic crowd would shout that 'the science is clear' when asked if eating too much animal protein will croak your kidneys, without a shred of supporting science. At least they've surely shouted it at us for the last 3 decades or more.

Here are translations of the first and final verses of what you heard if you listened:


SING, my tongue, the Savior's glory,

of His flesh the mystery sing;

of the Blood, all price exceeding,

shed by our immortal King,

destined, for the world's redemption,

from a noble womb to spring.


To the everlasting Father,

and the Son who reigns on high,

with the Holy Ghost proceeding

forth from Each eternally,

be salvation, honor, blessing,

might and endless majesty.

Amen. Alleluia.

There is increasing evidence that soft drink intake is associated with kidney disease, in addition to obesity and diabetes. There is strong experimental evidence, now both in humans and laboratory animals, that rehydration with soft drinks is injurious to the kidney. Our group has postulated that the intake of soft drinks by sugarcane workers may be playing a contributory role in the epidemic of chronic kidney disease observed in that population. However, to date epidemiological studies have not been able to show a clear link with soft drinks with kidney injury in this population. Whether this is because some of the sugary beverages contains beneficial components, such as salt (to replace salt losses from sweat), glucose (to prevent exercise-induced hypoglycemia) or other mechanisms is not known. We also cannot rule out the presence of additional toxins at this time. Nevertheless, the message is clear–drinking soft drinks is not a good way to rehydrate, and may actually cause kidney disease.

Thank you for your comment, Dr. Johnson!


You deserve a lot of credit for drawing attention to this impact of soft drinks, which is now being supported by human experiments. I personally doubt, though, that electrolyte solutions will "replace losses from sweat."


Experiments on salt packets and sports drinks have not found much if any effect on blood sodium. The dominant factor driving exercise associated hyponatremia is excessive fluid consumption, not inadequate sodium consumption. Sports drinks commonly have a 10-38 mmol/L sodium concentration, whereas I'm sure you're aware that the normal range for human plasma is 135-145 mmol/L. Moreover, it appears that during high-volume fluid consumption and physical exertion, human subjects do not retain sodium as they do at rest.

Thank you Russ Greene for this info on sodium concentration in sport drinks v.s. our body.

Jim, you seem to have unlimited energy! What’s your secret?


Struggling to get volume back up despite a pretty clean diet and getting good rest. Crashed out hard late 2017 by doing a 1/2 marathon then starting a new job.

Secret? Working hard and playing hard. Work out hard, then eat chocolate chip cookies and rum and cokes! Getting to bed at a decent hour has been important of late, too.

A key question in the sugar industry/CDC's early CKDu research is whether cause of this chronic kidney disease epidemic is “occupational.” That this remains a question indicates industry influence: how could the cause of a condition defined by its occupational circumstances not be “occupational?” CDKu isn’t killing Manhattan hedge fund managers or Tokyo attorneys; it’s killing agricultural workers in hot and humid environments. And yet, when the CDC launched its sugar-funded efforts in 2014, it stated “we don’t know” if labor practices had anything to do with the occupational illness. Much like Thank You For Smoking’s tobacco scientist, sugar industry-funded lead investigator Daniel Brooks explained,


“The Boston University team believes that the CKD epidemic is caused by a combination of factors … Results to date suggest that one or more of these causes are occupational, and more research is needed to identify the specific factors.”


As Clarke noted above,


"efforts to create doubt often push on two fronts - first, directly undermining existing evidence linking a particular item to a disease (e.g., sugar to CKD, as described here) and second, increasing the perceived need to consider alternative causes."

Listen to Missa Pange lingua? Is this an Open hint? Wikipedia says: "The hymn, in the Phrygian mode, is in six musical phrases, of 10, 10, 8, 8, 8, and 9 notes respectively, corresponding to the six lines of the hymn."

There is a second part of this story which parallels the link between sugar and obesity - deflection toward alternative causes.


As noted elsewhere on Crossfit's sites (see link below as one of many examples), efforts to create doubt often push on two fronts - first, directly undermining existing evidence linking a particular item to a disease (e.g., sugar to CKD, as described here) and second, increasing the perceived need to consider alternative causes. For obesity and diabetes, the sugar industry has most often deflected toward overall calorie consumption, lack of exercise, or lack of willpower as causes of metabolic unhealth. This has successfully positioned sugar as, at worst, one of many causes, and so undeserving of specific legislation or penalty. Here, we see a similar attempt to paint sugar as one of many potential causes, implying heat stress and dehydration are sufficient to explain the condition and so other causes need not be considered.

Another example where the danger is even less ambiguous, but the tactics similar? Asbestos.
