  A blood glucose test is used to measure the amount of glucose in the blood. These tests can be taken upon waking, after meals or at other times throughout the day. Glucose is a naturally occurring sugar found primarily in carbohydrates, and is a contributing factor to adult-onset diabetes and other blood sugar disorders. Blood glucose becomes naturally raised after meals, but elevated levels over extended periods of time can cause damage to eyes, nerves and blood vessels. Keeping a balanced diet and selecting certain foods can help balance these levels.
  
  

Whole Grains

• Whole grain foods, particularly oatmeal and barley, are naturally nutrient rich and are sources of high fiber. These factors have been shown to help maintain healthy blood glucose levels over a lifetime. Though these foods tend to be high in carbohydrates, it's considered a good carbohydrate. They are high in soluble fiber, which is slower to digest and reduces the risk of elevating blood sugars. Most nutritionists suggest an average of three servings per day to receive the most benefit, including reducing risk of type 2 diabetes and other problems associated with uncontrolled glucose levels. Those at risk for problems are encouraged to avoid starchy white foods, including white potatoes and high-sugar foods, most of which can be replaced with a whole grain alternative. Making these small dietary changes can improve health and reduce fluctuations in blood sugar.
  
  

Nonstarchy vegetables

• A group that includes broccoli, spinach and other greens has demonstrated a positive effect on diabetes sufferers. Essential to any diet, these foods provide high amounts of fiber, few carbohydrates and are low calorie, all factors that are ideal for diabetes and blood sugar control. Though starchy vegetables, such as corn, peas and winter squash provide similar nutrition, they also have more sugar, so maintaining proper portions is essential. In a study published in DiabetesCare, participants with type 2 diabetes who stuck to a vegetarian or vegan diet for 22 weeks were 43 percent more likely to discontinue use of diabetes medication. Additionally, these foods provide benefits for heart health as well.
  
  

Dairy

• Dairy products are an essential source of calcium and vitamin D, as well as a natural source of protein. Incorporating low-fat dairy products, including yogurt and skim milk can help reduce blood sugar problems when eaten in place of full-fat alternatives. Additional health benefits are being found in replacing dairy with soy-based foods, including milk, yogurt and other lactose-free products. Nutrition experts suggest at least three cups of dairy per day to maintain a balanced diet and preserve overall well-being.
