June is Men’s Health Month! This is a time to bring awareness to preventable health issues and encourage early detection of diseases affecting men. As we wind down from celebrating Father’s Day this past weekend, here are a few articles focusing on some important men’s health issues.
Lowering salt intake helps alleviate a number of health concerns, such as decreasing the risk of heart disease, stroke and stomach cancer. However, how easy is it to reduce your sodium intake without compromising taste, or your wallet? In a recent study, researchers sought to determine how feasible a low-sodium, inexpensive and nutritious meal for men could be. The authors used cost and nutritional data to model and optimize familiar diets. In this analysis, they showed that it is possible to decrease sodium levels to well below the recommended maximum, proving that nutrition does not need to be compromised when preparing an enjoyable low-cost meal.
So what should men be consuming to help with disease prevention? Olive plant leaves (Olea europaea L.) have been used in traditional medicine to treat diabetes for centuries. In a PLOS ONE clinical trial published this year, researchers investigated the effects of olive polyphenols on insulin balance. In this study, 46 male participants received either capsules of olive leaf extract or a placebo for 12 weeks. Through their observations, the researchers found that olive leaf extract significantly improved two factors related to Type 2 Diabetes (insulin sensitivity and pancreatic β-cell secretory capacity) in overweight, middle-aged men.
What about prostate health, you might ask? The Prostate Specific Antigen test, along with digital rectal examination is widely used for prostate cancer screening. PSA, which stands for Prostate Specific Antigen, is a glycoprotein secreted by epithelial cells of the prostate gland, and individuals with prostate cancer have a higher than normal amount of this compound in their systems. PSA levels can also change in response to external factors like surgery, though, so understanding these other forces is crucial for the test to be effective. In a recent study, authors investigated whether bike riding affects PSA concentration in men. The researchers took blood samples from 129 male participants 60 minutes before a bike ride and 5 minutes after completion. They found that cycling caused their PSA to increase an average of 9.5% when measured within 5 minutes after completing the ride. Based on these findings, the authors suggest a 24–48 hour period of abstinence from cycling before a PSA test to avoid any false positive results.
