The high-fructose corn syrup present
in the beverage increases salt re-absorption by cells in the kidneys, leading
to diabetes, obesity, kidney failure, and hypertension
A diet including soft drinks and sugar could negatively
affect your kidneys, new research has found.
Two new studies highlight the
potential negative effects that soft drinks and sugar can have on kidney
health.
In one study, researchers led by
Ryohei Yamamoto from Osaka University Graduate School of Medicine, in Japan, found that consuming
at least two soft drinks per day is linked with proteinuria - or increased
excretion of protein in the urine, which is a hallmark of kidney dysfunction.
Among 3579, 3055, and 1342 university
employees with normal kidney function at the start of the study who reported
that they drink zero, one, and two or more soft drinks per day, 301 (8.4 %),
272 (8.9 %) and 144 (10.7 %) employees developed proteinuria during a median of
2.9 years of follow-up, respectively.
Another study led by Agustin
Gonzalez-Vicente, from the Case Western Reserve University in US, conducted in rats found
that moderate fructose intake increases the kidney's sensitivity to angiotensin
II, a protein that regulates salt balance.
This leads to increased salt
re-absorption by cells in the kidneys, a finding that might help explain why
consumption of high-fructose corn syrup as a sweetener may contribute to the
epidemic of diabetes, obesity, kidney
failure, and hypertension, researchers said.
Results of these studies were
presented during ASN Kidney Week 2013 at the Georgia World Congress Center in
Atlanta, US.
