Summary:
This is the first large study to show the long term effects of eating
a lower sodium diet on cardiovascular outcomes (i.e. heart attack,
stroke, coronary angioplasty, coronary bypass surgery, and death from cardiac
causes). The authors were able to show that adults with pre-hypertension (mild
to moderate high blood pressure) aged 30 to 54 years, had 25% less cardiac
outcomes and death, simply by lowering salt intake alone from the usual amounts
commonly eaten in the United States. Nearly 2,500 study participants from
multiple sites were followed 10 – 15 years after being in a randomized
trial, Trials of Hypertension Prevention: TOHP 1 or TOHP II. Since cardiovascular
disease is the number one cause of death and disability in the U.S., this
study has major implications for having an impact on this problem. For the
full study results please see: http://www.bmj.com/cgi/content/short/bmj.39147.604896.55v1.
2. Salt intake is related to soft drink consumption in children and
adolescents: A link to Obesity? In this study the authors found a
significant association between salt intake and soft drink consumption among
children in Great Britian. The authors state that a decreased salt intake
might play a role in helping reduce childhood obesity because it might also
decrease the amount of sugary soft drinks that kids want to drink.
