Most of us eat too much salt that's hidden in processed foods. If food manufacturers switched to potassium salt we could all better protect our health & manufacturers still protect their profit margins with potassium-salty foods instead #Salt #SciComm #WHO #Health #processedFood #food #potassium
Why the WHO has recommended switching to a healthier salt alternative
It’s a positive step, but there will be a few challenges to realising the full benefits to public health.
