Looks like in the first week of spring scientists dotted many i's and crossed a lot of t's. The topics discussed in the articles listed in this week's collection include COVID research, connection between lifestyle diseases and nutrition and also something for the geeks in sports science. The highlights:
Eating before 8:30 a.m. could reduce risk factors for type 2 diabetes Intermittent fasting study finds eating earlier was associated with lower blood sugar levels and insulin resistance People who start eating before 8:30 a.m. had lower blood sugar levels and less insulin resistance, which could reduce the risk of developing type 2 diabetes, according to a new study.

However, a loose or improperly fitted helmet could leave them vulnerable to traumatic brain injuries (TBIs), a leading cause of death or disability in the U.S. Now researchers have developed a highly sensitive pressure sensor cap that, when worn under a helmet, could help reveal whether the headgear is a perfect fit.

New research has revealed drinking electrolytes instead of pure water can help prevent muscle cramps.

Source: University of Granada High vitamin D levels may protect against COVID-19, especially for Black people, study suggests In a retrospective study of individuals tested for COVID-19, vitamin D levels above those traditionally considered sufficient were associated with a lower risk of COVID-19.

Source: University of Leeds Dieting suppresses 'cellular engines', weight loss surgery gives boost to mitochondria Dieting impairs the energy-producing machinery of fat tissue, potentially resulting in weight regain Dieting impairs the energy-producing machinery of fat tissue, potentially resulting in weight regain. In contrast, as indicated by a recent study, weight loss surgery gives a boost to mitochondria, improving the gene expression of these cellular engines. Source: University of Helsinki 'Hunger hormone' ghrelin affects monetary decision making High ghrelin levels in healthy females predict more impulsive choices, researchers say Higher levels of the stomach-derived hormone ghrelin, which stimulates appetite, predict a greater preference for smaller immediate monetary rewards over larger delayed financial rewards, a new study finds. Source: The Endocrine Society Cells burn more calories after just one bout of moderate aerobic exercise, OSU study finds In a recent study testing the effects of exercise on overall metabolism, researchers found that even a single session of moderate aerobic exercise makes a difference in the cells of otherwise sedentary people. Source: Oregon State University Exercise boosts blood flow to the brain, study finds The results add to growing evidence that exercise programs may help older adults slow the onset of memory loss and dementia It's not just your legs and heart that get a workout when you walk briskly; exercise affects your brain as well. A new study shows that when older adults with mild memory loss followed an exercise program for a year, the blood flow to their brains increased. Source: UT Southwestern Medical Center Green leafy vegetables essential for muscle strength Eating just one cup of leafy green vegetables every day could boost muscle function, according to new research. The study found that people who consumed a nitrate-rich diet, predominantly from vegetables, had significantly better muscle function of their lower limbs.

Insomnia, disrupted sleep, and daily burnout are linked to a heightened risk of not only becoming infected with coronavirus, but also having more severe disease and a longer recovery period, suggests an international study of healthcare workers. Source: BMJ Did you find this information useful?
