Too much salt weakens the immune system
02/04/2020 - A high-salt diet is not only bad for one's blood pressure, but also for the immune system. Mice fed a high-salt diet were found to suffer from much more severe bacterial infections. Human...
Lower-sodium turkey breast wins sensory test over full-salt option
02/04/2020 - Food scientists produced a lower-salt processed turkey that consumers in a blind sensory test preferred to a full-salt version, according to a new study.
Ball-and-chain inactivation of ion channels visualized by cryo-electron microscopy
25/03/2020 - Ion channels, which allow potassium and sodium ions to flow in and out of cells, are crucial in neuronal 'firing' in the central nervous system and for brain and heart function. These...
New study debunks notion that salt consumption contributes to weight loss
26/02/2020 - Researchers found that reducing sodium intake in adults with elevated blood pressure or hypertension decreased thirst, urine volume and blood pressure, but did not affect metabolic energy needs....
Glutamate in the brain has unexpected qualities, researchers show with new analysis method
26/02/2020 - Researchers have achieved something long thought almost impossible -- counting the molecules of the neurotransmitter glutamate released when a signal is transferred between two brain cells. With a...
Lollies, vitamins and fish-shaped sauce containers hit the MRI mark
26/02/2020 - A study has identified four common items that could be cheaper and equally effective alternatives to commercial markers for use in MRI scanning to pinpoint specific anatomical areas or pathologies...
How low oxygen levels in the heart predispose people to cardiac arrhythmias
26/02/2020 - Low oxygen levels in the heart have long been known to produce life-threatening arrhythmias, even sudden death. Until now, it was not clear how. New findings reveal the underlying mechanism for this...
An atomic view of the trigger for the heartbeat
09/01/2020 - Tiny pores in heart cells generate electrical signals to initiate each heart beat. Structural studies of these channels provide details on their functions, and also on their malfunction due to...
Saccharin derivatives give cancer cells a not-so-sweet surprise
09/01/2020 - Saccharin received a bad rap after studies in the 1970s linked consumption of large amounts of the artificial sweetener to bladder cancer in laboratory rats. Later, research revealed that these...
Why zero-calorie sweeteners can still lead to diabetes, obesity
31/10/2019 - Increased awareness of the health consequences of eating too much sugar has fueled a dramatic uptick in the consumption of zero-calorie artificial sweeteners in recent decades. However, new research...
Research team advances research on metabolic syndrome
31/10/2019 - Building on their recent research focusing on a peptide designed to block the oxidant amplifying function of the cellular sodium-potassium pump, researchers have successfully demonstrated that...
Nonnutritive sweetener use in children
31/10/2019 - Nonnutritive or artificial sweeteners are a growing part of US diets, now consumed by at least one in four children. A new American Academy of Pediatrics policy statement offers a summary of the...
'No fat' or 'no sugar' label equals no guarantee of nutritional quality
31/10/2019 - Terms such as no-fat or no-sugar, low-fat or reduced-salt on food packaging may give consumers a sense of confidence before they purchase, but these claims rarely reflect the actual nutritional...
Low-sodium diet might not lower blood pressure
31/10/2019 - A new study that followed more than 2,600 men and women for 16 years found that consuming less sodium wasn't associated with lower blood pressure. The study adds to growing evidence that current...
Teens and adolescents who consume too much salt show unhealthy changes to blood vessels
31/10/2019 - Findings of a new study suggest adolescents who consume too much salt have measurable changes in their blood vessels associated with early signs of cardiovascular disease in adults.
