Most of us don't want to take prescription drugs unless we have to, and a recent study found that when it comes to diabetes, we might not have to rely on medication to control our blood sugar -- maintaining a healthy diet could be enough. The four-year study from Italy found that participants who were able to stick to the Mediterranean diet were able to lower their blood sugar levels and keep them down over time, suggesting that a healthy diet could reduce the need for diabetes medication. What's more, the study also found that the Mediterranean diet was more effective at controlling blood sugar levels than a traditional American Heart Association-style low-fat diet.

Participants in the study who followed the Mediterranean diet were encouraged to eat lots of fruits, veggies and lean protein, as well as moderate amounts of whole grains and healthy fats, like olive oil. Additionally, they were instructed that carbohydrate intake should be no more than 50 percent of their daily calories, and they reduced their overall calorie intake -- from an average of 1,800 to 1,500 for women, and 2,600 to 1,800 for men.

So, basically, then, healthy food and eating less improves your health? Uh, this isn't exactly news, but experts are still fairly excited about the findings because this is the longest study of it's kind thus far. Still, it's not completely clear whether diet alone is enough to eliminate the need for blood sugar medication, but one thing is obvious: Your are still what you eat.
