If you are one of the 98 million Americans with prediabetes or the more than 38 million with full-blown diabetes, it's important to keep up on the newest developments, insights, and alerts. Here are couple of the latest tools at hand — as well as a warning.

Prevention. A study in the journal Diet and Metabolism found that a nutritious plant-based diet (free of highly processed carbs, added sugars, and unhealthy fats) can cut your risk of diabetes by 24%.

Another study indicates that while walking 2-3 mph is helpful for preventing Type 2 diabetes, the faster you go, the more effective it is. Among more than 160,000 people, those who walked 3-4 mph were at a 24% lower risk for diabetes than those who walked more slowly.

Caution. If you have prediabetes or are diagnosed with Type 2 diabetes, you may be tempted to try some of the remedies and "medications" that show up online. The Food and Drug Administration wants you to know how risky that can be. Fake pharmacies and random websites tout untested remedies that have been found to contain prescription drugs that are not on the label, and many are contaminated with infectious agents or toxic chemicals.

To protect yourself, visit the "BeSafeRx" page at FDA.gov for more information about the potential dangers of buying drugs from unsafe websites and tips on safely purchasing medicines online.

And to make sure online pharmacies are legit, check out FDA.gov's "Locate a State-Licensed Online Pharmacy" page.
