- Salt plays multiple important roles in food, notably in preserving it and influencing how consumers perceive its taste.
- Research using sodium nuclear magnetic resonance (NMR) spectroscopies reveals that salted food interacts strongly with its matrix, affecting taste perception.
- Notably, some food samples showed unexpected sodium behavior that could have implications for quantitative MRI and enhancing our understanding of salty taste.
According to various health organizations, the global consumption of salt is higher than recommended and needs to be reduced. Ideally, this would be achieved without losing the taste of the salt itself. In order to accomplish this goal, both at the industrial and domestic levels, we need to understand the mechanisms that govern the final distribution of salt in food.

Each unitary scan consists of a selective slice (2D) or slab (3D) excitation followed by an evolution time and then the acquisition of the spatially encoded signal. It is critical that the phase variation during the evolution time for each scan is only dependent on chemical shifts.

- Real-time fMRI neurofeedback (rtfMRI-nf) targeting the left amygdala shows potential as a treatment for major depressive disorder (MDD) by improving neural connections and reversing depression-related impairments.
- The study investigates the link between rtfMRI-nf training and inflammatory markers, focusing on the kynurenine pathway, particularly the KynA/QA ratio, to assess neuroprotection.
- Results indicate that participants experienced a significant reduction in depressive symptoms after two sessions of rtfMRI-nf, suggesting a positive impact on mood and neurobiological markers.
