If you have type 2 diabetes, what you eat plays a big role in your blood sugar, or glucose levels. A rise in blood sugar after eating is normal. A large spike, however, can lead to hyperglycemia, or high blood glucose, which can have serious health implications.

The biggest factor in whether blood sugar spikes is the total number of carbs in your meal. But it also depends on the meal’s glycemic index (GI), which measures how quickly those carbs hit your system. If you choose foods low on the index, with a low glycemic load (or carbs per serving), it can help reduce spikes in blood sugar.

Here are a few low-glycemic foods people with type 2 diabetes can enjoy.
