In the world of health, information is changing all the time. Scientists are constantly researching cures for diseases, conducting studies that help us better understand the human body and sifting through current health advice to see what strategies are actually going to help us live longer, healthier lives. It can be hard to keep up. That’s why I’ve decided to check in on the latest in health news once a week to round up the most relevant studies that Canadians need to know to keep themselves well. Here are three of this week’s most important stories. 1. Drinking pop can hurt your kidneys. A study out of Japan found that people who drank more than two cans of pop a day were more likely to have protein in their urine, an early sign of kidney disease. According to the Kidney Foundation of Canada, the most common currently accepted causes of kidney disease are diabetes and high blood pressure. 2. Going for a run can help you remember where you put your keys. A Texas study has found that sedentary older adults who start aerobic exercise may improve their memories. As soon as six weeks after starting an exercise program, subjects experienced improved brain flow and other benefits. This comes after a study from earlier this year that said 30 minutes of exercise a day could significantly reduce a person’s risk of Alzheimer’s. 3. You may need an oil change. Research from the University of Toronto has shown that some oils that claim to be healthy may actually be contributing to heart disease. Many consumers believe that choosing any vegetable oil (as opposed to a saturated animal fat) means making a healthy choice, but things aren’t so simple. Safflower oil, for instance, may decrease cholesterol but increase cardiovascular disease. Overall, oils with plenty of omega-6 but little omega-3 proved to be not so heart healthy.
