What are the potential health conditions due to insufficient dietary fibre?
Most of us are aware of the causes of constipation and the most common cause is not eating enough fibre such as fruit, vegetables and cereals. So, you will eat more fruits and vegetables as well as drink more water to relieve constipation. Dietary fibre also lowers the risk of haemorrhoids and diverticulitis – constipation associated problems.
Nonetheless, the disorders that can arise from a low-fibre diet are more than constipation alone. Let’s have a look at other health conditions linked to a low-fibre diet:
- coronary heart disease - a narrowing of the arteries due to fatty deposits.
- diabetes - condition characterised by too much glucose in the blood.
- overweight and obesity - carrying too much body fat.
- colon cancer - a type of cancer of the large intestine.
What are the health benefits of high dietary fibre diet?
A high-fibre diet turns the disorders to in orders. Dietary fibre helps regulate the blood sugar and cholesterol levels in check, while, helps to keep you full for longer. Check out our blog on DIETARY FIBRE – All You Need to Know to find out the major roles by soluble fibre and insoluble.
Fibre and Heart Disease
Coronary heart disease also known as coronary artery disease is a type of heart disease that develops when the arteries of the heart are blocked and cannot deliver sufficient oxygen-rich blood to the heart. The blockage is caused by the build-up of plaque inside the lining of arteries as a result of high blood cholesterol levels.
Soluble fibre helps lower blood cholesterol by trapping the fat so they cannot all be absorbed into your bloodstream. How does it work? Fibre binds to fat and bile acids in your gut so the bile acids with the cholesterol are eliminated from your body rather than reabsorbed them. To replace the lost bile acids, your liver uses cholesterol to produce new bile acids, thus reducing blood cholesterol.
Fibre and Type-2 Diabetes
Blood glucose is a sugar which serve as your body main source of energy and comes mainly from food you eat. Unfortunately, type-2 diabetes occurs when your blood glucose is too high because your body is no longer able to regulate and uses the sugar.
For people with diabetes, fibre particularly soluble fibre can help regulates your blood sugar levels by slowing down conversion of carbohydrates into sugar delaying the absorption of sugar from the intestine. For those who want to reduce the risk of developing type-2 diabetes, have more fibre-rich foods and reduce high-glycaemic-index foods in your diet. This helps you to maintain lower blood sugar levels.
Fibre and Weight Control
Having your weight in control is about calories balancing between the number of calories you eat and you burn. And, for weight loss is about eating fewer calories than you burn.
Compared to low-fibre foods, fibre-rich foods tend to be more filling and therefore you are likely to eat less and take in fewer calories. Diet high in fibre will also leave you feeling fuller for longer because of cholecystokinin (CCK) – one of the hormones that controls the feeling of fullness. So, start eating more fibre because it helps increase the production of CCK and keeps it acting longer.
Keeping an eye on your weight, you decrease the risk of heart disease that can caused by being overweight and obesity.

Fibre and Colon Cancer
A high-fibre diet likely reduces your risk of developing colon cancer. Insoluble fibre helps maintain bowel health by increasing stools bulk and keeping your bowel movements regular. It is believed this will reduce the time of potential carcinogens have in contact with the walls of the colon. Besides, when bacteria in the intestines break down the insoluble fibre, butyrate, a short chain fatty acids (SCFAs), is produced which may inhibit the growth of cancer cell.
