Low D, Low Strength
The loss of muscle mass as we age is inevitable to an extent. However, we certainly want to fight to maintain our muscle mass. This is why resistance training becomes so important as we age. But what if there is another tool that can help us to maintain our muscle mass, strength, and function? A deficiency of this important vitamin can increase our risk of muscle loss by up to 78%. Read on to see which vitamin is this important. 
Metabolic Health and Cancer
Obesity is a risk factor for several cancers including pancreatic, postmenopausal breast, liver, colorectal, endometrial, and renal cell, and is often accompanied by metabolic problems like high blood glucose/diabetes, high blood pressure, and abnormal lipids. However, there is a group of people who are obese but don’t have all the metabolic dysfunction. Are they at the same risk as the others? Is the cancer risk only based on weight? What can we do to decrease our risk of developing these cancers? 
Is Running Bad for the Knees?
It has often been said that distance running will ruin your knees. But is this true? Are long-term runners at higher risk of knee arthritis? Is there an age one should stop running? What if a person already has some arthritis? Should they stop running? This study examined the data to find out.
