The
new enemy is salt. Here is an interesting example at an early stage of how
calls for legislation leap from study to implementation. A survey has
looked at salt.
In
the paper, Kirsten Bibbins-Domingo and colleagues, from the
University of California, San Francisco, USA, undertook a computer
simulation showing the effects of population wide reductions of
dietary salt intakes in all adults aged 35 to 85 years in the USA.
Reducing dietary salt intake by 3 g per day (1200mg less sodium per
day) could result in 60,000 to 120,000 fewer cases of heart disease ,
32,000 to 66,000 fewer strokes and 54,000 to 100,000 fewer heart
attacks.
Just
one study and even then, dietary recommendations are notorious for
lack of reliability. But the recommendation follows like day after
night:
A
reduction in dietary salt of 3g per day, the authors went on to say,
would have approximately the same effect on reducing cardiac events
as a 50 % reduction in tobacco use, a 5% reduction in body mass index
among obese adults or the use of statins to treat people at low or
intermediate risk for CHD events. Furthermore, reducing dietary salt
intakes by 3g per day would save $10 billion to $ 24 billion in
annual health care costs.
Precise,
costed benefits that bear little resemblance to reality, but a
comparison with the other devils of public health is utilised to
define a 'collective benefit'. Thus the call for legislation by the
European Society of Cardiology:
While
individuals may use salt sparingly at home, around 75 % of the salt
we eat is already in the food we buy. This, says the ESC, underlines
the need for legislation to lay down guidelines. "The reality of
international food production in Europe means that such public health
initiatives need to be tackled on a European wide basis, rather than
an individual country basis," said [Professor Frank] Ruschitzka.
Throw
in a publicity week and the NGO for good measure:
Salt
will again be on the agenda with World Salt Awareness Week 2010 ,
which runs from February 1- 7 (3). The week is being run by World
Action on Salt and Health (WASH), a global group that works with
governments to highlight the need for widespread introduction of
population based salt reduction strategies.
Add
salt!
