It's estimated that 99% of the world breathes air that exceeds the recommended limits for pollution. Air pollution increases your chances for heart and other disease. But it's not just air pollution that's a problem, noise pollution also can affect your heart. In this episode, we discuss the health risks of being exposed to pollution, how air and noise pollution affect your health and things you can do to reduce your pollution exposure.

The global weight loss industry will be worth $400 billion by 2030. And while most people who are trying to lose weight will say they're doing it for their health, your weight is not a good indicator of how healthy you are. In this episode we discuss how people started to equate weight with health, the role of excess body fat (and not weight) in health, what you need body fat for and when changes in weight are good and when they're not.

Sodium (and salt for that matter) has been made out to be the villain when it comes to nutrition. In fact, without sodium, you wouldn't be alive. While high amounts of salt in the diet are related to high blood pressure, the evidence to support a link with heart and other diseases isn't clear. In this episode we discuss why you need sodium, how much is too much, is sodium as harmful as we're told and how getting more potassium can help.
