For most of us, the anxiety-diet connection begins and ends with having too much coffee before work and experiencing those uncomfortable, anxious jitters afterward. But when you consider the profound influence your diet and lifestyle choices have on your overall well-being, the idea that what you put into your body influences your mental health isn't so farfetched.

With that said, it's also important to acknowledge the myriad of factors that subtly influence our mental health—just as there's more than one cause, there's more than one solution.
