Again in 1960, many of the world’s inhabitants was poor within the micronutrient iodine, with extreme penalties for public well being. By 2020, solely 21 international locations had been iodine-deficient – down from 113 in 1990 – and 90 per cent of individuals had been consuming sufficient.
The answer? Including iodine to desk salt. Iodisation of the salt provide was strongly supported by the salt trade and governments, and is arguably one of the crucial efficient public heath interventions of all time.
In 2024, the world is going through the same public well being disaster. Hypertension, or hypertension, is the main explanation for sickness and demise.
