Healthy Living

You only have one body, and you want to keep it healthy! Staying healthy involves making good choices every day about nutrition and exercise. It sounds simple, but understanding what those good choices are can be confusing. How much should you eat? What are empty calories? Why is exercise so important? What should your heart rate be, and what is the connection between heart rate, exercise, and staying healthy?

The projects and resources on this page will help you explore all these questions. You won't find boring lectures about how to eat better, how much to exercise, or what your ideal weight should be. Instead, you will find exciting hands-on projects and activities that help you understand the biology behind good nutrition and heart-healthy exercise and their connection to obesity and diseases. The more you know about the science of good health, the better choices you can make for your own health!
