In a new study, researchers demonstrate long-term, non-invasive monitoring of blood sodium levels using a system that combines optoacoustic detection with terahertz spectroscopy. The paper is ...

FDA issues new sodium guidelines, renewing pressure for food makers to use less salt The new guidelines do not reach the levels recommended for cutting the risk of heart attack and stroke.

Eating leafy greens and foods such as bananas may cut the risk of heart disease, irregular heartbeats and death by up to a quarter, a new study has shown. Potassium-rich foods, such as salmon, ...

The researchers also demonstrated that the terahertz optoacoustic system could quickly distinguish between high and low sodium levels in human blood samples.
