Fibre and Metabolic Health: A Connection- HealthifyMe

Along with fat and protein, fibre is a macronutrient that belongs to the carbohydrate family. A non-digestible carbohydrate called dietary fibre is present in food. A unique combination of bioactive substances, including resistant starches, vitamins, minerals, phytochemicals, and antioxidants, can be found in dietary fibre and whole grains.

Fibre largely bypasses our digestive system, causing blood sugar levels to rise less quickly than other carbs. In addition, short-chain fatty acid synthesis by the microbiota is encouraged by the presence of fibre, which can enhance metabolic health. Finally, since fibre slows down how quickly food is absorbed in the gut, fibre also seems to lower the risk of type 2 diabetes.

Whether you want to maintain ideal blood sugar levels or boost your metabolic health, HealthifyPro 2.0 can help. Using the device, integrated with BIOS, you can keep a track of how your dietary changes, including increasing fibre intake, contribute to improving blood glucose level fluctuations, and weight loss and thus result in better metabolic health. 

The HealthifyMe Note

Fibre has several health benefits, depending on the specific type. Intake of the recommended level of dietary fibre provides various benefits in metabolic and overall health. For example, it improves blood glucose levels, lowers the risk of developing cancers and chronic health conditions, and aids in sustainable weight loss.

Types of Fibre

Based on its solubility in water, it has two major categories:

Soluble Fibre

It dissolves in water and can undergo a metabolic process to feed the “good” bacteria in the gut. When soluble fibre dissolves in water, it transforms into a thick, gel-like substance that is highly fermentable (the process where gut microbes break down fibre). Hence, consuming soluble fibre promotes the maintenance of healthy fibre-digesting organisms in the gut microbiome.

Insoluble Fibre

Bulky insoluble fibre, which is less fermentable and doesn’t dissolve in water, aids in the transit of food through the gastrointestinal tract. It has been associated with decreased insulin resistance when consumed in large amounts. 

Both forms of fibres operate in tandem to regulate how your body consumes glucose. As a result, you stay satisfied for longer after consumption, which reduces your additional calorie intake. 

Based on these types, soluble and insoluble fibre can be classified into dietary or functional categories: 

Dietary Fibre 

Dietary fibre is naturally present in whole food sources, including fruits, vegetables, whole grains, and legumes. The dietary fibre category comprises the types: soluble, insoluble, fermentable, and non-fermentable.

Functional Fibre 

It is either synthetically produced or derived from whole food sources like starches or other sugar components. Functional fibre is initially isolated from the sources and then added to certain foods to produce in the form of supplements.

Adequate Fibre Intake

The ideal fibre intake varies depending on a person’s gender, age, and life stage, like pregnancy etc. 

Recommended daily fibre intake for adults :       

  • For men: 30g of fibre each day
  • For women: 25g of fibre each day

Recommended daily fibre intake for children

  • Children (4 to 8 years): 18g      
  • Girls (9 to 13 years): 20g     
  • Girls (14 to 18 years): 22g       
  • Boys (9 to 13 years): 24g       
  • Boys (14 to 18 years): 28g

Fuels the Gut (Good) Bacteria

Many bacteria, protozoa, fungi, and viruses that make up the gut microbiome also require fibre. To maintain a diverse gut microbiome, you should consume a diet high in fibre. It is the main factor in determining the importance of (specific) dietary fibre for health. By acting as prebiotics, they nourish the “good” bacteria in the colon.

Strengthens Immunity

Fibre plays a vital role in immunity. Research suggests that fibre is a good source of good bacteria in the gut. Therefore, it helps destroy harmful bacteria and provides good bacteria nutrients. 

Produces Beneficial Short-Chain Fatty Acids

The beneficial bacteria create crucial short-chain fatty acids like butyrate and acetate for the body. These short-chain fatty acids help nourish colonic cells, reducing gut inflammation and improving conditions like ulcerative colitis, irritable bowel syndrome, and Crohn’s disease. In addition, consuming fibre-rich foods impacts insulin sensitivity and glucose absorption.

Aids in Digestion

Fibre helps improve bowel movements as the fibre absorbs water in the intestines and softens the stool. Thus, resulting in a smooth pass out of the stool. 

Research suggests that dietary fibre intake increases stool frequency in patients with constipation.

Helps Protect the Gut Lining

Besides maintaining the gut’s mucus layer, a physical barrier to keep infections out, fibre also helps reduce inflammation. The immune system launches an inflammatory reaction if the mucus layer is damaged, and germs can penetrate it. These pathogens may be invasive microbes or those that already reside in the gut. Butyrate, a short-chain fatty acid, has anti-inflammatory characteristics that promote mucosal immunity and intestinal barrier health.

Keeps Inflammation Down

Fibre controls inflammation by nourishing gut bacteria. Most prebiotics, which provides food for the bacteria already present in your gut, fall under the dietary fibre category (probiotics, in contrast, add new ones). Prebiotics supports the balance of gut microbes that are both

Anti-inflammatory and pro-inflammatory. 

Dysbiosis, a condition where some gut microbes thrive while others fail, is caused by imbalances in the gut microbiota. It is directly associated with metabolic abnormalities, gut inflammation, and diseases like obesity, inflammatory bowel disease, and malnutrition.

Studies suggest that long-term dietary fibre intake can reduce the risk of inflammatory bowel disease. The data was collected from 170,776 women and followed up over 26 years.

Aids in Weight Management

Dietary fibre can regulate calorie intake, thus enhancing weight loss or maintaining healthier body weight. In addition, studies show that increasing dietary fibre intake improves satiety.

Prevents Type-II Diabetes

As per research, the consumption of whole grains and a variety of regularly consumed whole-grain foods, such as whole-grain morning cereal, oatmeal, dark bread, brown rice, and added bran, has a direct linkage with a decreased risk of type 2 diabetes. In addition, the fibre in the whole grain slows down the breakdown of starch into glucose, leading to steady blood sugar levels. Therefore, dietary fibre can help prevent type-II diabetes.

Helps in Reducing Cholesterol Level

The presence of fibre in the digestive system can lessen the body’s absorption of cholesterol. Therefore, it is particularly accurate if you use psyllium fibre supplements and statins, drugs to decrease cholesterol.

Promotes Blood Sugar Control

High-fibre foods may take longer for your body to process. Also, this makes it easier to maintain more stable blood sugar levels, which benefits those with diabetes.

Reduces Gastrointestinal Cancer Risk

Consuming sufficient fibre can help prevent some cancers, including colon cancer. There are numerous explanations for this, one of which is the possibility that particular forms of fibre, like the pectin in apples, may have antioxidant-like qualities.

Foods Rich in Fibre

The HealthifyMe Note

Dietary Fibre holds an undeniable role in a healthy lifestyle and balanced diet. Several studies have reinforced the positive influence of fibre on health, from its functional capabilities as a prebiotic to a metabolic manager. However, if you plan to add more fibre to your diet, take it slow so that you don’t experience any side effects or intestinal discomfort.

Side Effects of Too Much Fibre

Even though dietary fibre is crucial for metabolic fitness, consuming

Too much fibre might result in potential health threats. The symptoms include,

  • Bloating
  • Abdominal pain
  • Flatulence
  • Loose stools or diarrhoea
  • Constipation
  • Temporary and unexpected weight gain
  • Intestinal blockage in patients with Crohn’s disease
  • Decreased blood sugar levels, which is vital to know if you have diabetes       
  • Increased risk of depression
  • Heart-related conditions

Prevention and Treatment for Too Much Fibre

The symptoms of overeating fibre can be reduced by:

  • Reducing fibre consumption        
  • Increasing fluid consumption        
  • Getting more exercise
  • Avoiding food that increases bloating

Summary

Adding dietary fibre to your diet is one of the effective ways to improve your overall metabolic health, considering its myriad health benefits. For example, fermentable fibre provides food for the gut bacteria and converts to short-chain fatty acids, which are ideal for your colon wall. Viscous, soluble fibre may also lessen hunger, lower cholesterol, and reduce blood sugar spikes following high-carb meals. 

Try to consume whole fruits, veggies, and grains high in a range of fibre if you want to lead a healthy lifestyle and ensure the right proportion of fibre. However, it will help if you exercise caution. Avoid making any abrupt, significant adjustments to your fibre consumption.

Knowing how much and what type of dietary fibre will control glucose metabolism in people with diabetes, pre-diabetes, and other risk conditions is essential. Nonetheless, incorporating dietary fibre into your daily diet will likely bring about positive metabolic changes in the body over time. In addition, it will add more flavour and variety to your plate.
