research study on effect of fiber on heart patients

According to an article, the prevalence of diabetes, cardiovascular diseases has increased by over 50% from 1990 to 2016 in India

Cardiovascular diseases are one of the leading causes of death around the globe. This is not new for us that high blood pressure and diabetes are conditions that increase the chances of cardiovascular diseases in an adult. Fortunately, in recent years consumers, researchers, and even the food industry are seeking more and more interest as to how food products can be improved to maintain the overall health of a person. Evidently, dietary fiber has been part of the diet for preventing issues related to the heart since the 1970s.

25 percent of adults consume the recommended amount of fiber on a daily basis.

About the Research:

Researchers from a hospital in Amritsar, India conducted a study with 200 adults suffering from Type 2- Diabetes and Hypertension. The research took over a period of 6 months to complete. Incidentally, the objective of the research study was to find out the effect of consumption of dietary fiber to lower the risk of diabetes, high blood pressure.

  • Recommended dietary allowance for fiber- 40 gm/2000kcal.
  • Fiber intake of the patients in the study- 24-30 gm /1200-1500kcal
  • Percentage of fiber intake increased-  25 percent 

In addition to this, they were provided with diet prescriptions in regional languages. The prescription provided, described different food items with the required portions. The doctors also explained the diet charts through counseling sessions with the help of audio-visual equipment. 

Over six months, the study tracked 200 patients including check-ups. For exact results, every three months and six months, the participants were checked. Moreover, the patients send pictures of the meals through WhatsApp. This helped to track their fiber intake as well as portion sizes. Also, the doctors called them thrice a week to track complete dietary recall.

Apparently, the researchers found that a high-fiber diet can improve several factors that can contribute to several cardiovascular diseases. The factors that improved are-

  • Reduction in serum cholesterol by 9%
  • Depletion in triglyceride level by 23%
  • Cutting in systolic blood pressure by 15%
  • Trimming in fasting blood sugar by 28%

A high number of findings suggested that there has been a lower incidence of cardiac issues. There are two types of fiber that act together to regulate these doctors. Undoubtedly, another finding was the soluble fiber decreases serum and cholesterol levels and improves resistance to insulin. Besides this, majorly the insoluble fiber works to control and lower the chances of any cardiovascular diseases (CVD). 

Previous Studies:

Originally, it was believed that bad cholesterol in the intestines is caught by fiber before it can be absorbed by the blood. The bad cholesterol is passed out as waste. But the new study reveals that the fiber works by increasing the number of gut bacteria. The gut bacteria digest the fiber into small parts known as short-chain fatty acids (SCFAs). The fatty acids-

  • Improve lipid metabolism
  • Lower cholesterol
  • Control blood sugar
  • Reduce inflammation

Importance of Both Types of Fiber

It is important to note that consuming only one type of fiber is not sufficient. The combination of both soluble and insoluble fiber can prevent diseases related to the heart. 

  • Soluble fiber lowers unhealthy LDL cholesterol. It slows down digestions as well as controls blood glucose in diabetics. Some of the foods rich in fiber are beans, oats, and peas. 
  • Insoluble fiber prevents constipation and removes waste from the body. Insoluble-fiber rich food items are wheat bran, whole grains, fruits with their skin.


The cardiovascular health of people with high blood pressure and diabetes can improve by increasing fiber intake. If you eat more than 25 percent of the required amount, you’ll be able to see the benefits. Fiber enhances the overall health of the body. If you don’t consume the required amount of dietary fiber on a daily basis, you are at the risk of developing other ailments such as chronic constipation. This can give rise to other complications such as piles. If you are already suffering from piles, opt for the most advanced painless laser surgery. Even after the treatment, incorporate fruits and vegetables into your diet on a regular basis in order to avoid such illnesses.
