Coffee and cinnamon have made headlines recently as foods that might be able to cut the risk of diabetes or help to improve blood sugar levels. But don't get the idea that such foods are magic bullets for your diabetic diet, experts warn.

"None of this is a magic potion for diabetes," says American Dietetic Association spokeswoman Cathy Nonas, RD. It's still important for people with diabetes to eat a balanced diabetic diet and exercise to help manage the disease, she says.

6 Tips to Get Your Diabetes Under Control

Living well with type 2 diabetes means making certain precautions part of your routine, says Amy Campbell, MS, RD, CDE, manager of clinical education programs at Joslin Diabetes Center in Boston. She offers this advice. Make a date with a dietitian. "It's a myth that there's a one-size-fits-all diabetes diet," Campbell says. A dietitian can help you develop an eating plan that's right for your age, weight, activity level, and medications, and can also set daily calorie and carbohydrate targets...

Nevertheless, some foods, such as white bread, are converted almost right away to blood sugar, causing a quick spike. Other foods, such as brown rice, are digested more slowly, causing a lower and gentler change in blood sugar.

If you are trying to follow a healthy diabetic diet, here are six that may help to keep your blood sugar in check.


Oatmeal can help control blood sugar -- but don't get the sweetened kind.

"Even though it's a carbohydrate, it's a very good carbohydrate," American Dietetic Association spokeswoman Marisa Moore, RD, LD, tells WebMD. Because it's high in soluble fiber, "it's slower to digest and it won't raise your blood sugar as much or as quickly. It's going to work better at controlling blood sugar over time."

Not only does this high-quality carbohydrate offer a steadier source of energy than white bread, it can also help with weight loss. The soluble fiber in oats "helps to keep us feeling fuller longer," Moore says.

That's important for people with type 2 diabetes, who tend to be overweight. "If you reduce the weight, you usually significantly improve the glucose control," Nonas says.

Barley isn't as popular as oats. But there's some evidence that barley, which is also high in soluble fiber, may also help with blood glucose control. Kay Behall, PhD, a research nutritionist at the USDA Beltsville Human Nutrition Research Center, has studied barley, and she suggests that people try eating boiled pearl barley in place of rice.

Besides oats and barley, Moore adds, "most whole grains are going to be a great choice for a person with diabetes."
