​Check out the past week's published articles on everything fitness, nutrition and sports science. Intriguing subjects on the plate including link between activity and mood, how exercise may be an answer for the ageing population living with dementia and there is one for the fitness gadget geeks too!

Feel free to share these with your personal training clients. Here are the highlights:
​

• ​Replacing time spent sitting with sleep or light activity may improve your mood
• ​Exercise improves memory, boosts blood flow to brain
• ​Adding a blend of spices to a meal may help lower inflammation
• ​How the body makes triglycerides
• ​Implantable biosensor operates without batteries
• ​Higher fiber saves lives, but food processing may remove benefits
• High doses of vitamin D supplementation has no current benefit in preventing or treating COVID-19

Replacing time spent sitting with sleep or light activity may improve your mood

New research found that substituting prolonged sedentary time with sleep was associated with lower stress, better mood and lower body mass index (BMI), and substituting light physical activity was associated with improved mood and lower BMI across the next year.

Higher fiber saves lives, but food processing may remove benefits

Eating more fiber can improve life expectancy for those with diabetes, researchers say. Type 2 diabetes has reached epidemic proportions worldwide, is associated with serious medical complications, and increases the risk of dying from COVID-19.

High doses of vitamin D supplementation has no current benefit in preventing or treating COVID-19

Scientists have published a vitamin D consensus paper warning against high doses of vitamin D supplementation as current research shows it has no benefit in preventing or treating Covid-19. Scientists advise that the population adhere to Public Health England guidance on supplementation.
