 In this week's latest publications, you'll find a range of topics around nutrition, fitness and exercise science. It looks like certain supplements are being investigated thoroughly. At the same time, studies around the effects of exercise on our health are also ongoing. The paper on the diets of children and teens is alarming, though. The highlights:
Do vitamin D supplements offer kidney-related benefits for individuals with high diabetes risk? Trial shows no significant effects on kidney outcomes In a clinical trial of individuals at high risk for developing type 2 diabetes, which is the leading cause of kidney disease, vitamin D supplementation did not have significant effects on kidney health. As participants were not selected according to baseline vitamin D levels, investigators cannot exclude a kidney benefit for individuals with vitamin D deficiency.

Researchers found that resistance-like exercise regulates fat cell metabolism at a molecular level.

Source: Edith Cowan University Study identifies molecule that stimulates muscle-building in humans In a randomized control study of 10 healthy young men, researchers compared how consuming the single amino acid leucine or its two-molecule equivalent, dileucine, influenced muscle-building and breakdown. They found that dileucine boosts the metabolic processes that drive muscle growth 42% more than free leucine does.

The study found the most benefit for younger stroke survivors. When people under the age of 75 exercised at least that amount, their risk of early death was reduced by 80%.

Researchers can use this to find novel therapies for vascular disorders of the muscle.
