CONCLUSIONS—Increased insoluble dietary fiber intake for 3 days significantly improved whole-body insulin sensitivity. These data suggest a potential mechanism linking cereal fiber intake and reduced risk of type 2 diabetes.
Fiber is a type of carbohydrate that your body can't digest, so you should subtract the grams of fiber from the total carbohydrate. On Nutrition Facts food labels, the grams of dietary fiber are already included in the total carbohydrate count.
Two types of fiber — both are important“Soluble fiber is helpful in lowering unhealthy LDL cholesterol. It also helps slow down digestion and can assist with controlling blood glucose in diabetics. You can find soluble fiber in foods such as beans, oats, and peas,” said Wood.
According to the 2015–2020 Dietary Guidelines for Americans, women aged 19–30 years should consume 28 g of fiber a day, and men 33.6 g. An article published in 2015 recommends that people with diabetes should eat at least this much fiber each day.
Fiber is a type of carbohydrate that the body can't digest. Though most carbohydrates are broken down into sugar molecules, fiber cannot be broken down into sugar molecules, and instead it passes through the body undigested. Fiber helps regulate the body's use of sugars, helping to keep hunger and blood sugar in check.
Bottom Line: Soluble fiber, especially from whole foods, has been shown to increase insulin sensitivity and lower insulin levels, particularly in people with obesity or type 2 diabetes.
Bad carbohydrates (Low fiber content)
- Rapidly digested. Rapidly digested foods cause a spike in the level of blood sugar (The spike triggers the pancreas to make more insulin, which is a hormone that makes the body store more fat.)
- Processed foods.
- Increases the risk of heart disease, diabetes, and obesity.
FIber does not contribute to weight gain or raise blood sugar levels. As for the second point, some high-fiber foods (such as avocados, non-starchy vegetables, and nuts) are low-carb, but others, such as fruits and whole grains are almost nothing but carbs.
Fiber is a carbohydrate that your body can't digest, so it doesn't count toward the amount of carbs that can trigger an insulin response, which too much of can prevent your body from going into that ketosis state.
Both soluble and insoluble fiber have their own benefits. Soluble fiber can help improve digestion and lower blood sugar, while insoluble fiber can soften stool, making it easier to pass.
Foods containing high levels of soluble fiber include dried beans, oats, oat bran, rice bran, barley, citrus fruits, apples, strawberries, peas, and potatoes.
Try Barley and OatmealBoth contain the fiber beta-glucan, which improves insulin action, lowers blood sugar, and helps sweep cholesterol from the digestive tract, Weisenberger says. One cup of cooked barley contains 6 grams of fiber and one cup of cooked oatmeal contains about 4 grams, according to the USDA.
Too much fiber in the diet can cause bloating, gas, and constipation. A person can relieve this discomfort by increasing their fluid intake, exercising, and making dietary changes. These uncomfortable side effects of excessive fiber can occur when someone eats more than 70 grams (g) of fiber a day.
Good sources of soluble fibre include:
- Oats.
- Fruits and berries, particularly apples, strawberries and blueberries.
- Nuts and seeds.
- Beans, pulses and lentils.
- Vegetables.
First, they may slow gastric filling, due to their bulking and energetic dilution capacity, which might in turn slow gastric emptying. Secondly, when certain soluble fibres are mixed in liquid meals or in liquid/solid meals, they delay emptying of gastric liquids by increasing viscosity of gastric contents.
One cup (128 grams) of chopped carrots contains 4.6 grams of dietary fiber, 2.4 of which are soluble (27). Since many people enjoy this vegetable daily, it can be a key source of soluble fiber.
Fiber is a unique form of carbs in terms of its digestion and effects on your body. Unlike starch and sugar, naturally occurring fiber isn't absorbed in your small intestine.
Although there is no dietary reference intake for insoluble or soluble fiber, many experts recommend a total dietary fiber intake of 25 to 30 grams per day with about one-fourth — 6 to 8 grams per day — coming from soluble fiber.
A study published in today's Annals of Internal Medicine suggests that something as simple as aiming to eat 30 grams of fiber each day can help you lose weight, lower your blood pressure, and improve your body's response to insulin just as effectively as a more complicated diet.
What happens if you don't eat the right amount of carbs when you have diabetes? If you eat more carbohydrates than your insulin supply can handle, your blood sugar level goes up. If you eat too little, your blood sugar level may fall too low.
Experts agree, the best way to keep digestion on track is to increase consumption of fiber in all its many forms. Eat a varied diet that includes whole grains, fruits, vegetables, nuts, seeds, and legumes.
Women should aim for 25 grams of fiber per day, while men should target 38 grams, or 14 grams for every 1,000 calories. Dietary fiber contributes to health and wellness in a number of ways. First, it aids in providing fullness after meals, which helps promote a healthy weight.
For example, if a food has 5 or more grams of fiber per serving, you can subtract half the amount of fiber from the total number of carb grams. A food that has 30 grams of carbs and 8 grams of fiber would be counted as 26 grams of carbs.
For optimal health, choose complex carbohydrates found in whole foods, as they're high in fiber. Examples include beans, oatmeal, 100 percent whole-wheat bread, quinoa, barley, potatoes, and sweet potatoes. These foods are also naturally rich in vitamins, minerals, and phytochemicals.

American Diabetes Association RecommendationsIf you have Type 1 Diabetes and do not use an insulin-to-carb ratio (ICR) or if you have Type 2 Diabetes: Count the Total Carbohydrates listed on the Nutrition Facts Label. Do not subtract any fiber or sugar alcohols.
in an 8 oz. glass of water once a day), then gradually increase the dose as needed. Your health care provider may recommend higher doses of psyllium to treat certain conditions. You can take psyllium first thing in the morning or before bedtime.
Answer From Michael F. Picco, M.D. There's no evidence that daily use of fiber supplements — such as psyllium (Metamucil, Konsyl, others) or methylcellulose (Citrucel) — is harmful. Fiber has a number of health benefits, including normalizing bowel function and preventing constipation.
Since psyllium creates intestinal bulk and has laxative effects, this substance may pose adverse side effects. You may be especially prone to side effects if you're new to psyllium or if you take more than the recommended amount per day. Some of the possible side effects include: abdominal pain and cramps.
Toward the end of your fast, you might want to introduce small portions of foods that are more easily digested, so you don't overwhelm your digestive system. Breaking your fast with foods that are especially high in fat, sugar, or even fiber can be difficult for your body to digest, leading to bloating and discomfort.
The amount needed to lower cholesterol is 10 to 20 grams a day. Psyllium is generally taken three times a day, just before each meal, either in a capsule or as a powder that you mix with water or juice.
Psyllium usually produces a bowel movement within 12 to 72 hours. Do not take psyllium for longer than 7 days in a row without a doctor's advice.
For an adult, a dose of psyllium husk is taken once, twice or three times a day. The powder or granules should be mixed into a full glass (8 ounces) of water or fruit juice before swallowing. Capsules should be swallowed whole with a full glass (8 ounces) of water. It is best if you take your doses just after a meal.
CAN I ADD METAMUCIL POWDER TO MY COFFEE OR HOT TEA ? No, adding Metamucil to hot beverages causes it to gel more rapidly. We recommend adding Metamucil to cool or cold liquids.
Psyllium husk also functions as a powerful anti-inflammatory which happens to be the most important feature of this fiber. Some important studies have been done on the effects of psyllium husk on ulcerative colitis.
