An analysis of 13 studies on the effects of reducing salt has found that a difference of five grams per day is associated with a 23 per cent difference in the rate of stroke and a 17 per cent difference in the rate of total cardiovascular disease, reports FoodBusinessNews.net.
The results of the analysis were published in the British Medical Journal last month.
FoodBusinessNews.net reports that higher salt intake is associated with a higher incidence of strokes and total cardiovascular events.
A reduction in salt intake of five grams per day at the population level each year could avert about 1.25 million deaths from stroke and almost three million deaths from cardiovascular disease.
Salt reduction trend
Mintel, a U.S.-based market research firm, says sodium reduction will be one of the leading trends for consumer packaged goods manufacturers in 2010.
Mintel reports that 51 per cent of U.S. consumers say they always or usually watch their sodium levels.
The research firm also reports that food production introductions containing a low, no or reduced sodium claim have increased by nearly 115 per cent from 2005 to 2008.
Less sodium, better bone health
In other news, FoodNavigator.com reports on a study out of Australia that has found that switching to low-salt products may also benefit bone health by reducing calcium loss.
Middle-aged women with pre- or stage 1 hypertension assigned to consume a low-sodium diet experienced reductions in calcium excretion compared to people consuming a high-carbohydrate low-fat diet, according to findings published in the British Journal of Nutrition, reports FoodNavigator.com.
