This bitesize episode features Dr Elisa Pineda, a researcher working at the forefront of nutrition and chronic disease prevention. Elisa shares new insights into how simple dietary changes—like swapping regular salt for potassium‑enriched salt—could significantly reduce high blood pressure and the risk of heart disease. She discusses why this work matters, what communities are telling researchers, and how governments and the food industry can help make healthier choices easier and more accessible for everyone.
