Understanding the Glycemic Index of Raisin Bran
For people with type 2 diabetes, monitoring the glycemic index (GI) of foods is an important way to help manage blood sugar levels. The glycemic index measures how much and how quickly a food raises blood glucose levels. Foods with a high GI cause faster and more significant increases in blood sugar compared to foods with a low GI.
Raisin bran is a common breakfast cereal made from wheat bran flakes and raisins. But how does it rate on the glycemic index scale? And is raisin bran a healthy choice for people with type 2 diabetes?
The Glycemic Index of Raisin Bran
The glycemic index of raisin bran ranges from moderate to high depending on the brand. According to Harvard Health, most raisin bran cereals fall between 56–58 on the GI scale. A GI of 56 or more is considered high.
For comparison, table sugar has a GI of 65 and white bread has a GI of about 70. So while raisin bran doesn't spike blood sugar to the same level as pure sugar or white bread, it can still cause a noticeable surge.
Why Raisin Bran Has a High GI
There are two main reasons why raisin bran tends to have a moderate to high GI:
- It's made with refined grains
- It often contains added sugars
Most raisin bran is made from refined grains like white flour or white wheat bran. Refining strips away much of the fiber and nutrients in whole grains, leaving mainly the starchy endosperm. Without fiber to slow digestion, the starch gets rapidly broken down into glucose, leading to faster and larger increases in blood sugar.
Additionally, many brands add sugar to raisin bran to sweeten the taste. The raisins also contribute natural sugars. So the combination of refined grains and added sugars causes raisin bran's stronger impact on blood glucose.
Healthier Bread Choices for Diabetes
Due to its high GI, raisin bran cereal isn't the best option for managing type 2 diabetes. So what breads and cereals are better choices? Here are some healthy options:
1. Whole Grain Breads
Whole grain breads like whole wheat or multigrain are healthier picks because they're made from the entire grain. This gives them more fiber and nutrients than refined grains.
For example, pumpernickel bread is a coarse rye bread that contains the whole rye berry. It has a low GI of about 50 and contains gut-healthy fibers that can help regulate blood sugar response.
2. Sourdough Breads
Sourdough breads can also be a good choice because the fermentation process helps reduce the GI. One study found sourdough bread had a GI of 54 compared to regular white bread which had a GI of 70.
When choosing sourdough, still opt for whole grain options whenever possible to get the benefits of added nutrition and fiber.
3. Sprouted Grain Breads
Sprouted grain breads are made from whole grains that have been allowed to sprout before baking. The sprouting makes the grains easier to digest and lowers the GI.
In one study, sprouted grain bread had a GI of 51 while regular whole wheat bread had a GI of 71. Plus sprouted grains retain more vitamins and minerals compared to other breads.
4. Seeded Breads
Seeded loaves that contain chia seeds, flax seeds, pumpkin seeds or sunflower seeds also aid blood sugar control. The healthy fats and fiber in the seeds helps slow glucose absorption and lower the GI of the bread.
Opt for sprouted seeded breads whenever possible to get the combined blood sugar benefits.
Other Tips for Managing Diabetes with Diet
Aside from making smart bread choices, here are some other diet tips that can help manage type 2 diabetes:
Include Non-Starchy Vegetables
Fill half your plate with non-starchy vegetables at meals. Options like leafy greens, broccoli, peppers, and carrots are full of nutrients. And they're low in carbs and calories which helps control blood sugar and weight.
Choose Healthy Fats
Healthy fats like olive oil, avocado and nuts help regulate blood sugar levels. They also give you satiety so you feel fuller after eating which helps manage weight and diabetes risk.
Increase Your Fiber Intake
Getting adequate fiber from whole grains, fruits, vegetables and legumes supports healthy blood sugar control. Aim for at least 25 grams of fiber per day.
Drink More Water
Staying hydrated with water instead of sugary drinks removes excess sugar from your diet. It also aids circulation and helps the body better utilize insulin and glucose.
Making smart dietary choices tailored to blood sugar management can empower people with diabetes. Consult a nutritionist or dietitian to create a meal plan that fits your health goals.
FAQs
What is the glycemic index of raisin bran cereal?
The glycemic index of most raisin bran cereals ranges between 56–58. This is considered high on the GI scale, though not as high as white bread or pure sugar.
Is raisin bran healthy for people with diabetes?
No, raisin bran is generally not the best cereal choice for people with diabetes. Due to containing refined grains and added sugars, raisin bran can spike blood sugar quite quickly after eating it.
What breads are healthiest for managing diabetes?
Some good bread options for controlling blood sugar include sprouted whole grain breads, seeded breads, sourdough breads, and high fiber whole grain breads like pumpernickel.
What other diet tips help manage type 2 diabetes?
Some additional ways to manage diabetes through diet include eating more non-starchy veggies, choosing healthy fats like nuts and olive oil, increasing fiber intake, staying hydrated, and working with a nutritionist to develop a tailored meal plan.
