Reducing dietary salt is recommended by the recent United Nations Summit to prevent non communicable diseases and the World Health Organization to improve population health. Excess dietary salt increases blood pressure causing approximately 30% of hypertension and is a probable pro carcinogen for gastric cancer and is also associated with kidney stones and osteoporosis.
Where assessed, the salt consumption is more than 5/g day, maximum quantity recommended by WHO. African descent people are particularly susceptible to the adverse blood pressure effects of excess salt. High levels of blood pressure is a contributory factor in at least 40% of all heart disease and stroke which represent 45 % of NCDs. Hypertension is a major health risk in the Americas where between 20-35% of the adult population has elevated blood pressure.
