Fibre Reduces Insulin – How To Lose Weight X
When we consider the nutritional benefits of food, we think about the vitamins, minerals and nutrients they contain. We think about components in the food that nourish the body. Fibre is completely different. The key to understanding fibre’s effect is to realize that the benefit lies not as a nutrient, but as an anti-nutrient. Fibre has the ability to reduce absorption and digestion. Fibre subtracts rather than adds. In the case of sugars and insulin, this is good. Soluble fibre reduces absorption of carbohydrates, which in turn reduces blood glucose and insulin levels. In one study, type 2 diabetic patients were given liquid meals containing 55% carbohydrates with or without the addition of dietary fibre. Fibre reduced both the glucose and the insulin peaks, despite consuming exactly the same amount of carbohydrates. Fibre acts as an anti-nutrient. Because insulin is the main driver of obesity and diabetes, reduction is beneficial. In essence, fibre acts as a sort of ‘antidote’ to the carbohydrate, which, in this analogy, is the ‘poison’. Carbohydrates, even sugar, are not literally poisonous, but comparison is useful to understand the effect of fibre. It is no coincidence that virtually all plant foods, in their natural, unrefined state contains fibre. Mother Nature has pre-packaged the ‘antidote’ with the ‘poison’. Thus, traditional societies may follow diets high in carbohydrate without evidence of obesity or Type 2 Diabetes. The Okinawans, for instance, base their diet upon the sweet potato, and consume an estimated 80% of their calories as carbohydrate. High fibre protects against obesity. Until recently, they were one of the longest-lived peoples on earth. The Kitavans of New Guinea followed a diet estimated to be close to 70% carbohydrate with Continue reading >>

Fibre is the part of plants that our bodies cannot digest. There are two types of fibre: soluble and insoluble. Foods such as vegetables, fruits, legumes and whole grains contain fibre. Animal foods such as meats and eggs have no fibre. What is the difference between soluble and insoluble fibre? Soluble fibre is the soft fibre that helps control blood glucose (sugar) and reduces cholesterol. It also helps in managing diarrhea. Soluble fibre is present in oat bran, oatmeal, legumes (dried beans and lentils) and fruits such as apples and strawberries. Insoluble fibre is the bulky fibre that helps to prevent constipation. It also helps to prevent some types of cancers. It is present in wheat bran, whole grain breads and cereals, fruits and vegetables. Many foods contain both soluble and insoluble fibre. Why is fibre good for me? Fibre is important for your overall health. Some of its benefits include: Controlling blood glucose (sugar) Managing blood pressure Reducing blood cholesterol Increasing the feeling of being full Controling weight Regulating bowel movement Benefit for those with diabetes Soluble fibre in oat bran, legumes (dried beans of all kinds, peas and lentils), and pectin (from fruit, such as apples) and forms in root vegetables (such as carrots) is considered especially helpful for people with either form of diabetes. Soluble fibre may help control blood sugar by delaying gastric (stomach) emptying, retarding the entry of glucose into the bloodstream and lessening the postprandial (post-meal) rise in blood sugar. It may lessen insulin requirements in those with type 1 diabetes. Because fibre slows the digestion of foods, it can help blunt the sudden spikes in blood glucose (sugar) that may occur after a low-fibre meal. Such blood sugar peaks stimulate the pa Continue reading >>
Carbohydrates And Blood Sugar
When people eat a food containing carbohydrates, the digestive system breaks down the digestible ones into sugar, which enters the blood. As blood sugar levels rise, the pancreas produces insulin, a hormone that prompts cells to absorb blood sugar for energy or storage. As cells absorb blood sugar, levels in the bloodstream begin to fall. When this happens, the pancreas start making glucagon, a hormone that signals the liver to start releasing stored sugar. This interplay of insulin and glucagon ensure that cells throughout the body, and especially in the brain, have a steady supply of blood sugar. Carbohydrate metabolism is important in the development of type 2 diabetes, which occurs when the body can’t make enough insulin or can’t properly use the insulin it makes. Type 2 diabetes usually develops gradually over a number of years, beginning when muscle and other cells stop responding to insulin. This condition, known as insulin resistance, causes blood sugar and insulin levels to stay high long after eating. Over time, the heavy demands made on the insulin-making cells wears them out, and insulin production eventually stops. Glycemic index In the past, carbohydrates were commonly classified as being either “simple” or “complex,” and described as follows: Simple carbohydrates: These carbohydrates are composed of sugars (such as fructose and glucose) which have simple chemical structures composed of only one sugar (monosaccharides) or two sugars (disaccharides). Simple carbohydrates are easily and quickly utilized for energy by the body because of their simple chemical structure, often leading to a faster rise in blood sugar and insulin secretion from the pancreas – which can have negative health effects. Complex carbohydrates: These carbohydrates have mo Continue reading >>
How Does Soluble Fiber Affect The Glycemic Index To Help With Diabetes?
How does soluble fiber affect the glycemic index to help with diabetes? Janis Jibrin, MS, RD on behalf of The Best Life Soluble fiber, the type of fiber found in oats, barley, psyllium, beans, and certain fruits and vegetables, lowers the glycemic index (GI) of a food in a few different ways. When it mixes with liquid and with your own digestive juices, it forms a gel which slows the rate at which your stomach empties. Once in the small intestine, that gel forms a protective layer around starch particles, making it difficult for enzymes to penetrate. In studies in which people with diabetes took in 10 to 20 milligrams of soluble fiber daily for weeks, their average blood sugar was lowered slightly. After the soluble fiber makes its way to the large intestine, it becomes a meal for friendly bacteria, which convert dietary fiber into short-chain fatty acids that appear to help your blood sugar in two ways. Their presence sends a signal to the liver to stop making glucose and they also appear to increase insulin sensitivity. Diabetes mellitus (MEL-ih-tus), often referred to as diabetes, is characterized by high blood glucose (sugar) levels that result from the bodys inability to produce enough insulin and/or effectively utilize the insulin. Diabetes ... is a serious, life-long condition and the sixth leading cause of death in the United States. Diabetes is a disorder of metabolism (the body's way of digesting food and converting it into energy). There are three forms of diabetes. Type 1 diabetes is an autoimmune disease that accounts for five- to 10-percent of all diagnosed cases of diabetes. Type 2 diabetes may account for 90- to 95-percent of all diagnosed cases. The third type of diabetes occurs in pregnancy and is referred to as gestational diabetes. Left untreated, g Continue reading >>

It is accepted that viscous and gel-forming properties of soluble DF inhibit macronutrient absorption, reduce postprandial glucose response, and beneficially influence certain blood lipids. Colonic fermentation of naturally available high fiber foods can also be mainly attributed to soluble DF, whereas no difference between soluble and insoluble DF consumption on the regulation of body weight has been observed.

Fiber does not affect your blood sugar levels. 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. But because fiber is a type of carbohydrate that your body can’t digest, it does not affect your blood sugar levels. You should subtract the grams of fiber from the total carbohydrate. Here’s the best advice about fiber: For people with diabetes that are treated with insulin, getting the most accurate carbohydrate count may help control blood sugars better. To summarize – you need to take the total amount of carbohydrate in a serving MINUS the carbohydrate in the fiber. Now, let’s practice using the sample food label: The dietary fiber is 5 grams per serving. Count this product as 5 grams of carbohydrate (10 grams total carbohydrate minus 5 grams dietary fiber equals 5 grams of carbohydrate).

Do Apples Affect Diabetes And Blood Sugar Levels?
Apples are delicious, nutritious and convenient to eat. Studies have shown that they have several health benefits. Yet apples also contain carbs, which impact blood sugar levels. However, the carbs found in apples affect your body differently than the sugars found in junk foods. This article explains how apples affect blood sugar levels and how to incorporate them into your diet if you have diabetes. Apples are one of the most popular fruits in the world. They're also highly nutritious. In fact, apples are high in vitamin C, fiber and several antioxidants. One medium apple contains 95 calories, 25 grams of carbs and 14% of the daily value for vitamin C (1). Interestingly, a large part of an apple's nutrients is found in its colorful skin (2). Furthermore, apples contain large amounts of water and fiber, which make them surprisingly filling. You're likely to be satisfied after eating just one (3). Apples are a good source of fiber, vitamin C and antioxidants. They also help you feel full without consuming a lot of calories. If you have diabetes, keeping tabs on your carbohydrate intake is important. That's because of the three macronutrients — carbs, fat and protein — carbs affect your blood sugar levels the most. That being said, not all carbs are created equal. A medium apple contains 25 grams of carbs, but 4.4 of those are fiber (1). Fiber slows down the digestion and absorption of carbs, causing them to not spike your blood sugar levels nearly as quickly (4). Studies show that fiber is protective against type 2 diabetes, and that many types of fiber can improve blood sugar control (5, 6). Apples contain carbs, which can raise blood sugar levels. However, the fiber in apples helps stabilize blood sugar levels, in addition to providing other health benefits. Apples Continue reading >>
How Does Eating Affect Your Blood Sugar?
Part 1 of 8 What is blood sugar? Blood sugar, also known as blood glucose, comes from the food you eat. Your body creates blood sugar by digesting some food into a sugar that circulates in your bloodstream. Blood sugar is used for energy. The sugar that isn’t needed to fuel your body right away gets stored in cells for later use. Too much sugar in your blood can be harmful. Type 2 diabetes is a disease that is characterized by having higher levels of blood sugar than what is considered within normal limits. Unmanaged diabetes can lead to problems with your heart, kidneys, eyes, and blood vessels. The more you know about how eating affects blood sugar, the better you can protect yourself against diabetes. If you already have diabetes, it’s important to know how eating affects blood sugar. Part 2 of 8 Your body breaks down everything you eat and absorbs the food in its different parts. These parts include: carbohydrates proteins fats vitamins and other nutrients The carbohydrates you consume turn into blood sugar. The more carbohydrates you eat, the higher the levels of sugar you will have released as you digest and absorb your food. Carbohydrates in liquid form consumed by themselves are absorbed more quickly than those in solid food. So having a soda will cause a faster rise in your blood sugar levels than eating a slice of pizza. Fiber is one component of carbohydrates that isn’t converted into sugar. This is because it can’t be digested. Fiber is important for health, though. Protein, fat, water, vitamins, and minerals don’t contain carbohydrates. These components won’t affect your blood sugar levels. If you have diabetes, your carbohydrate intake is the most important part of your diet to consider when it comes to managing your blood sugar levels. Part 3 Continue reading >>

Stable levels of glucose and insulin may prevent interprandial feelings of hunger and, consequently, increased activity. Catheterized sows (n = 10) were fed twice daily (0700 and 1900 h) 900 g of a diet with either a low (L-sows) or a high level of fermentable dietary fiber (H-sows; sugarbeet pulp). Blood samples, taken between feeding times, were analyzed for glucose and insulin levels (basal and area under the curve) and stability of levels (variance and sum of absolute differences between level Continue reading >>
6 Reasons A High-fiber Diet Is Insanely Healthy For Diabetes
Fiber directly improves insulin sensitivity iStock A number of studies have found that eating more dietary fiber for a period of weeks or months is linked to a reduction in biomarkers for insulin resistance. This may be due in part to dietary fiber’s anti-inflammatory effects—high-fiber diets have been associated with reduced blood levels of C-reactive protein, a marker for systemic inflammation—and also to the fact that the short-chain fatty acids that fiber produces when it ferments in the intestinal tract tend to inhibit the breakdown of the body’s fat stores into free fatty acids. This breakdown of fat stores appears to play a major role in creating insulin resistance in the skeletal muscles. iStock Soluble fiber’s general effect of slowing down the digestive process means that the carbohydrates we eat take longer to be broken down into glucose. As a result, the release of glucose into the blood after eating tends to occur more slowly over a longer period of time following a high-fiber meal. This means that glucose doesn’t rise to as high a peak after eating, putting less stress on the glucose metabolism process. iStock The same fermentation process that signals the body to become more responsive to insulin also suppresses glucose production in the liver—countering the liver’s glucose overproduction that occurs as the result of insulin resistance. Fiber makes you feel more full so it’s easier to eat less iStock A number of studies have found that people who eat diets high in fiber feel more full after eating and also feel less hungry between meals. For starters, dietary fiber is simply bulkier than other nutrients. This causes the stomach to become more distended when you eat fiber, which sends appetite-suppressing signals to the brain.

Nutrition And Healthy Eating
Eat more fiber. You've probably heard it before. But do you know why fiber is so good for your health? Dietary fiber — found mainly in fruits, vegetables, whole grains and legumes — is probably best known for its ability to prevent or relieve constipation. But foods containing fiber can provide other health benefits as well, such as helping to maintain a healthy weight and lowering your risk of diabetes and heart disease. Selecting tasty foods that provide fiber isn't difficult. Find out how much dietary fiber you need, the foods that contain it, and how to add them to meals and snacks. What is dietary fiber? Dietary fiber, also known as roughage or bulk, includes the parts of plant foods your body can't digest or absorb. Unlike other food components, such as fats, proteins or carbohydrates — which your body breaks down and absorbs — fiber isn't digested by your body. Instead, it passes relatively intact through your stomach, small intestine and colon and out of your body. Fiber is commonly classified as soluble, which dissolves in water, or insoluble, which doesn't dissolve. Soluble fiber. This type of fiber dissolves in water to form a gel-like material. It can help lower blood cholesterol and glucose levels. Soluble fiber is found in oats, peas, beans, apples, citrus fruits, carrots, barley and psyllium. Insoluble fiber. This type of fiber promotes the movement of material through your digestive system and increases stool bulk, so it can be of benefit to those who struggle with constipation or irregular stools. Whole-wheat flour, wheat bran, nuts, beans and vegetables, such as cauliflower, green beans and potatoes, are good sources of insoluble fiber. Most plant-based foods, such as oatmeal and beans, contain both soluble and insoluble fiber. However, the amo Continue reading >>
Effects Of Dietary Fiber And Carbohydrate On Glucose And Lipoprotein Metabolism In Diabetic Patients
Dietary recommendations for the treatment of diabetic patients issued by national and international diabetes associations consistently emphasize the need to increase carbohydrate consumption. However, these recommendations have been questioned on the basis of growing evidence that, in both insulin-dependent and non-insulin-dependent diabetic patients, a high-carbohydrate diet does not offer any advantage in terms of blood glucose and plasma lipid concentrations compared with a high-fat (mainly unsaturated) diet. It has been shown repeatedly that a high-carbohydrate diet increases plasma insulin and triglyceride levels and can deteriorate blood glucose control in the postprandial period. However, much of the controversy between advocates and detractors of dietary carbohydrate can be settled by taking into account dietary fiber. Several studies have shown that the adverse metabolic effects of high-carbohydrate diets are neutralized when fiber and carbohydrate are increased simultaneously in the diet for diabetic patients. In particular, these studies demonstrated that a high-carbohydrate/high-fiber diet significantly improves blood glucose control and reduces plasma cholesterol levels in diabetic patients compared with a low-carbohydrate/low-fiber diet. In addition, a high-carbohydrate/high-fiber diet does not increase plasma insulin and triglyceride concentrations, despite the higher consumption of carbohydrates. Unfortunately, dietary fiber represents a heterogenous category, and there is still much to understand as to which foods should be preferred to maximize the metabolic effects of fiber. There are indications that only water-soluble fiber is active on plasma glucose and lipoprotein metabolism in humans. Therefore, in practice, the consumption of legumes, vegetable Continue reading >>

More Evidence That A High-fiber Diet Can Curb Type 2 Diabetes
People who ate more than 26 grams of fiber a day had an 18 percent lower risk of developing type 2 diabetes than those who ate 19 grams a day or less Fiber may benefit diabetes by altering hormonal signals, slowing down nutrient absorption or altering fermentation in the large intestine, along with promoting feelings of satiety and weight loss The majority of your fiber should come from vegetables, not grains By Dr. Mercola In the US, nearly 80 million people, or one in four has some form of diabetes or pre-diabetes. One in two people with diabetes do not know they have it,1 which increases the odds of developing complications, which can be deadly. Leading a healthy lifestyle is one of the best strategies to prevent, and treat, type 2 diabetes, and even more specifically, eating a high-fiber diet is emerging as a key strategy you can use to lower your risk. More Than 26 Grams of Fiber a Day May Lower Your Diabetes Risk US dietary guidelines call for adults to consume 20-30 grams of fiber per day. I believe an ideal amount for most adults is around 50 grams per 1,000 calories consumed. Most people, however, get only half that, or less. In a recent study conducted by researchers at the Imperial College London, those who had the highest intake of fiber (more than 26 grams a day) had an 18 percent lower risk of developing type 2 diabetes than those with the lowest intake (less than 19 grams a day).2 The fiber may benefit diabetes by altering hormonal signals, slowing down nutrient absorption or altering fermentation in the large intestine, along with promoting feelings of satiety.3 Eating a high-fiber diet is also associated with weight loss, and the researchers believe this may, in turn, lower diabetes risk. In fact, when the researchers accounted for participants' BMI, th Continue reading >>
How Fiber Helps Control High Blood Sugar
Are you filling up on fiber? If you have type 2 diabetes, you should be — including high-fiber foods in your diet is a healthy way to control high blood sugar. As an added bonus, you may be able to stay full longer on the correct portion sizes than you would if you were eating more refined foods. And eating lots of soluble fiber (the kind found in oatmeal, beans, and apples, among other foods) may help reduce dangerous visceral belly fat, according to a recent study. "Fiber promotes good bowel health, lowers the risk of cancer and heart disease, and also controls your blood sugar in a certain way," explains Amy Kranick, a registered dietitian and certified diabetes educator with the adult diabetes program at Vanderbilt University Medical Center in Nashville, Tenn. When fiber is digested, your body handles it differently than the way in which refined carbohydrates, such as white flour, are digested. A portion of the fiber simply passes through your digestive system intact. This difference means that eating foods rich in fiber is less likely to cause a spike in high blood sugar. "Fiber doesn't require insulin [to digest], so it isn't counted as part of your carbohydrates," says Kranick. As a result, when you are reading labels and budgeting daily carbohydrates, you can subtract half the grams of dietary fiber from the total carbohydrate count. At the same time, you should be keeping track of how much fiber you eat. Adults need at least 25 grams of fiber daily for best health outcomes, says Kranick. Other Benefits of Fiber Fiber may also help you manage your overall eating habits, says Kranick. Here are some of the additional benefits of eating high-fiber foods: Antioxidants. Many of the foods that contain fiber also contain antioxidants, which are generally good for you Continue reading >>
Does Taking Fiber Help Regulate Blood Sugar?
Dietary fiber, the undigestible component of plant foods, improves digestive health by preventing constipation, hemorrhoids and diverticular disease. Because it expands in your digestive tract, fiber slows digestion, which makes you feel full longer so you're less likely to overeat. Fiber also lowers cholesterol levels by preventing cholesterol from being absorbed, and slows the absorption of glucose, reducing your risk for developing Type 2 diabetes. Various forms of fiber have different effects on the digestive process and offer different blood sugar-management benefits. Beta-Glucan and Post-Meal Blood Sugar Reduction A form of soluble fiber called beta-glucan, found in barley and oats, reduced post-meal blood sugar spikes in a study published in the December 2012 issue of "European Journal of Nutrition." Scientists fed laboratory animals diets containing barley flour for six weeks. Results showed lower levels of glycated hemoglobin -- a blood marker that indicates blood sugar levels for two to three months prior to the test -- in the beta-glucan-supplemented group compared to a control group. The treatment group also had higher levels of adiponectin, a hormone secreted by fat cells that promotes energy burning and glucose utilization. Peas and Glucose Tolerance The outer seed coats of peas might lower blood sugar by improving glucose tolerance -- the ability of cells to absorb glucose from the bloodstream -- according to an animal study published in the August 2012 issue of the "British Journal of Nutrition." Supplementation with pea coats improved absorption of glucose by muscle cells and decreased fasting blood sugar and insulin secretion. Additionally, the size of the insulin-producing cells of the pancreas decreased by 50 percent, indicating less demand placed on Continue reading >>
