You've been managing your diabetes like a Pro!

....Checking your blood sugar, taking medication, eating healthy. But your doctor has recently recommended increasing your fiber intake. "What gives?" you wonder. It turns out fiber plays an important role in stabilizing blood sugar. Packing your plate with fiber-rich foods helps slow digestion and keep you full longer, preventing those nasty blood sugar spikes. Fiber also keeps things moving through your system smoothly (wink, wink). Luckily, delicious high-fiber options abound. We're talking nuts and seeds, berries, oatmeal, broccoli, chana - all the good stuff. So read on, to learn how to pump up the fiber and take your diabetes management to the next level. This is one change that could make a big difference!

What Is Dietary Fiber and Why Is It Important for Diabetics?

Dietary fiber refers to plant-based carbohydrates like cellulose, lignin and pectin that your body can’t digest. Fiber, especially soluble fiber found in foods like beans, broccoli and oats, helps to slow the absorption of sugar into your bloodstream. For diabetics, a high-fiber diet with at least 25-30 grams per day can help keep blood sugar in a healthy range, and may even reduce the need for medication.

It Keeps You Feeling Full

Fiber expands in your stomach, helping you feel satiated and full and therefore, controlling the appetite. This can help to prevent overeating and promote weight loss, which also indirectly controls your blood sugar. High-fiber snacks like nuts, seeds and fresh veggies with hummus are perfect for keeping you full between meals.

It Slows Sugar Absorption

Soluble fiber forms a gel-like substance in your gut, and this helps to slow down the digestion of carbohydrates. This helps to prevent blood sugar spikes and reduces the glycemic impact of high-carb meals. Focus on soluble fiber from nuts, seeds, rolled oats, beans, broccoli, cauliflower.

It Improves Insulin Sensitivity

A high-fiber diet may help the cells to respond better to insulin and improve your body’s ability to use insulin, effectively. This can help in lowering insulin resistance and make it easier for your cells to absorb blood sugar. Ground flax seeds, chia seeds and leafy greens are excellent sources of fiber that may aid insulin sensitivity.

A fiber-rich diet should be a key part of any diabetes-management plan. Fiber provides so many benefits for blood sugar control and overall health. Ensure that at least half your grains are whole grains, eat lots of non-starchy veggies, fruits, nuts and beans, and stay hydrated to get the most from all that fiber. Your body—and blood sugar—will thank you!

Best High Fiber Foods for Diabetics

Diabetics, know that fiber is your friend. It helps to slow down the absorption of glucose into the bloodstream and reduces blood sugar spikes. Boosting your fiber intake is one of the best ways to keep Type 2 diabetes in check. It is best to get fiber from a wide variety of whole, minimally processed plant foods as the best sources. 

Some of our top favourite fiber foods:

  • Fruits - Berries, apples, pears, oranges contain both soluble and insoluble fiber.
  • Vegetables - Broccoli, Brussels sprouts, carrots, leafy greens, cauliflower, beans, peas.
  • Whole grains - Oats, barley, brown rice, quinoa, whole wheat bread.
  • Legumes - Kidney beans, lentils, chickpeas, black beans, soybeans.
  • Nuts and seeds - Almonds, walnuts, chia seeds, flaxseeds.
  • Artinci’s High Fiber desserts - made with nuts and seeds, millets, prebiotic sweetener


A single cup of chickpeas packs a whopping 15 grams of fiber in it. Chickpeas are also high in protein and loaded with nutrients like manganese, folate and copper. Add chickpeas to your salad, make hummus, or toss them in a curry.

Chia Seeds

Just one ounce of chia seeds contains 11 grams of fiber, plus they're a great source of omega-3 fatty acids. Chia seeds are extremely versatile - sprinkle them on yogurt or oatmeal, add to a smoothie, or make chia pudding.


A cup of raspberries contains 8 grams of fiber and only 80 calories. Berries also contain antioxidants that can help reduce inflammation in the body. Raspberries make a delicious snack all on their own, or add them to cereal, salads or yogurt.


One cup of chopped broccoli has 5 grams of fiber and is packed with vitamin C, folate and antioxidants. Broccoli is great, raw or cooked - steam it, roast it, or add it to stir fries.


A one-cup serving of oatmeal made with rolled oats and water has 4 grams of fiber. Oatmeal is high in soluble fiber which helps lower cholesterol and keep you feeling full. Top your oatmeal with nuts, seeds, fruit and cinnamon, for extra nutrition and crunch.

How Fiber Helps Manage Blood Sugar and Diabetes

Slows Sugar Absorption

Fiber, especially soluble fiber, is a prebiotic, which feeds the good bacteria in your gut and helps to slow the absorption of sugar (blood glucose) into your bloodstream. Foods like oatmeal, beans and broccoli are high in soluble fiber that forms a gel-like substance in your gut. This gummy fiber creates a physical barrier that prevents sugar from entering your bloodstream too quickly after a meal. The slower absorption means your blood sugar rises more gradually instead of spiking rapidly. For diabetics, stabilizing blood glucose levels is key to managing the condition.

Lowers Cholesterol

High fiber diets have been shown to lower LDL or “bad” cholesterol. Soluble fiber binds to cholesterol particles in your gut and helps to remove them from your body before they can be absorbed. Lowering your cholesterol reduces your risk of heart disease, a common complication of diabetes. Aim for at least 5 to 10 grams of soluble fiber each day, from foods like oats, beans and vegetables.

Promotes Satiety

Fiber fills you up and satisfies your hunger, because it takes longer to digest. Eating more fiber with each meal leads to increased feelings of fullness, so you're less likely to overeat or snack unnecessarily between meals. This can aid weight management and make it easier for you to control portion sizes — both important for blood sugar control and reducing diabetes complications. Most experts recommend 25 to 35 grams of fiber per day for good health. Focus on high-fiber whole foods at each meal to boost your intake.

In summary, a high-fiber diet should be a key part of any diabetic management plan. Fiber works in multiple ways to help stabilize blood sugar, lower cholesterol, and keep you feeling full. Make fiber-rich foods a staple in your meals and you'll be well on your way to better health.

Tips for Adding More Fiber to Your Diet

One of the best ways for diabetics to manage blood sugar levels is by upping fiber intake. Fiber helps in slowing down the digestion of carbohydrates and the absorption of sugar into the bloodstream. Slowly adding more high-fiber foods to your diet will help avoid discomfort from gas or bloating.

Choose fresh over frozen

Whenever possible, choose fresh vegetables, fruits and whole grains instead of frozen options. Fresh produce will provide more fiber, gram for gram. The great part about living in India is the diversity of fresh vegetables available year-round. It is a great idea to follow the seasons in local geography and buy fresh vegetables which are in prime season.

Include vegetables at each meal

Aim for filling half your plate with vegetables at each meal. Doing so will significantly boost your daily fiber intake. Some high-fiber options include berries and avocados which provide 8 grams of fiber per serving. Vegetables like cauliflower, green peas and broccoli are also great options with over 4 grams of fiber per half cup.

Add beans and legumes

Beans and legumes are high in fiber, protein, and complex carbohydrates. Add them to soups, salads, or enjoy as a side dish. A single cup of kidney beans packs over 15 grams of fiber. Hummus, made from chickpeas, has over 5 grams of fiber per half cup. Lentils are also a great option with 8 grams of fiber per half cup, cooked.

Choose whole grains

Whenever possible, choose whole grain breads, cereals and pastas over refined and white grain options. Look for “whole wheat” or “whole grain” as the first ingredient. Whole wheat bread has 3 to 5 grams of fiber per slice compared to less than 1 gram in white bread (do read the label to ensure it has only whole wheat as the flour ingredient though!) Brown rice when cooked, has 3.5 grams of fiber per cup versus only 0.6 grams for the same amount of white rice. Making a simple switch to whole grains can add more fiber to your diet, throughout the day.

Dietary Fiber FAQs: Your Most Pressing Questions Answered

What exactly is dietary fiber?

Dietary fiber refers to the indigestible parts of plant foods like fruits, vegetables, grains and legumes. There are two types of fiber: soluble and insoluble. Soluble fiber dissolves in water and helps control blood sugar levels and cholesterol. Insoluble fiber aids digestion and helps prevent constipation. A high-fiber diet provides many benefits for overall health and in managing diabetes.

Why is fiber important for diabetics?

Slows down blood glucose: Fiber, especially soluble fiber, helps in slowing down the absorption of sugar into the bloodstream. This is because soluble fiber forms a gel-like substance when it mixes with liquids in your stomach. This gel slows down the movement of food through your digestive tract and the absorption of carbohydrates into your bloodstream. By slowing carbohydrate absorption, soluble fiber helps control blood sugar spikes after meals, maintaining steadier glucose levels and reducing the risk of blood sugar spikes and crashes. 

Prebiotic Properties: Dietary fiber acts as a prebiotic by feeding beneficial gut bacteria. This influences the composition of your gut microbiome, which is important for overall health. 

Reduces Insulin Resistance: Soluble fiber is fermented by gut bacteria into short-chain fatty acids, such as butyrate, in the colon. Butyrate has several health benefits, including providing energy for colon cells and having anti-inflammatory properties, where it helps reduce insulin resistance

Weight Management and Satiety: Fiber helps you feel fuller for longer by slowing digestion and increasing satiety, which can aid in weight management.

Reduces Bad Cholesterol: Fiber also reduces LDL or “bad” cholesterol levels in the blood, which diabetics tend to struggle with. Adding more fiber to your diet can help you better manage diabetes and lower your health risks.

How much fiber do I need each day?

Most nutrition experts recommend 25 to 30 grams of fiber per day, for good health. If you have diabetes, aim for the higher end of that range, around 28 to 30 grams daily. Focus on getting fiber from whole foods like beans, broccoli, berries, and whole grains. If needed, you can also take a fiber supplement to help you meet your daily needs.

Are fiber supplements safe?

Fiber supplements such as psyllium husk or inulin powder, can be part of a healthy diet for diabetics. However, always talk to your doctor before taking any supplement. Fiber supplements may interact negatively with some medications. They can also cause side effects like gas, bloating or diarrhea in some people. It is best to get fiber from whole foods when possible, and only use supplements occasionally or under medical guidance.

What are the best high-fiber foods for diabetics?

Some of the best high-fiber foods for diabetics include beans, broccoli, Brussels sprouts, carrots (lightly cooked), peas, greens like lettuce or spinach (lightly cooked), sweet potatoes, all berries, avocados, and whole grains like Rolled Oats, local Millets and Quinoa. Aim for a wide variety of these foods with each meal to boost your fiber intake and manage your blood sugar. Staying hydrated and drinking plenty of water will also help the fiber work best in your body.
