5 Benefits of Bioflavonoids for our Body

on June 01, 2020

Bioflavonoids, also known as flavonoids, are a collection of naturally existing polyphenolic compounds all over the plant kingdom. They are produced by plants for protection against predators and are a natural antioxidant. They are also responsible for the natural color of plants and fruits. There are about 5000 different known varieties of flavonoids that are used for different purposes, such as supplements, medicine, and health.

Flavonoids are the most common group of polyphenolic compounds present in our diet and function majorly to boost our immune system and help protect us from diseases. They are found in several plants around us and are subdivided into flavonols, flavones, flavanols, flavanones, anthocyanidins, proanthocyanidins, and isoflavones. We can consume a tremendous amount of bioflavonoids in food because they are widely distributed in plant crops.

 

The Importance of Bioflavonoids For Our Body

Flavonoids usually accompany vitamin C in fruit and vegetables and might influence its absorption and utilization by the body. Their other critical biological functions include:

 

  • Flavonoids reduce upper respiratory tract infections (URTIs): Research shows that flavonoids possess physiological effects such as anti-inflammatory, antiviral, antioxidant, cytotoxic, antiproliferative, antireplicative, and antimicrobial effects. These physiological effects of bioflavonoids act to reduce inflammation in the upper respiratory tract of humans and aid in decreasing the occurrence of URTIs.
  • They are excellent antioxidants: One of the most remarkable properties of flavonoids is their ability to act as antioxidants. This feature allows them to scavenge free radicals that are responsible for causing oxidative stress in our bodies. Oxidative stress is a risk factor for many pathological conditions such as heart diseases, cancer, liver diseases, and many other diseases. The flavonoids act by suppressing the formation of reactive oxygen species (ROS), scavenging ROS, and upregulating antioxidant defenses.
  • They help to prevent cancer: Diet plays a crucial role in preventing the occurrence of cancer. Research has shown that fruits and vegetables which contain bioflavonoids help to prevent cancer. For instance, the consumption of onions and apples which have a high amount of flavonoid, quercetin, has shown to suppress the onset of prostate and lung cancer. Also, moderate wine (contains flavonoids) drinking appears to slow down the development of lung, endometrium, and colon cancer.
  • Bioflavonoids protect the heart: They have been reported to exert beneficial actions on the heart and, therefore, useful in the treatment or management of atherosclerosis. Luteolin, apigenin, and genistein are three flavonoids that can be used in managing high blood pressure because of their antihypertensive activity.
  • They help reduce fat: Flavonoids help scavenge oxidized low-density lipoprotein (LDL), which is commonly referred to as bad cholesterol. Oxidation of LDL is one of the major causes of heart-related diseases.

 

Bioflavonoids and the Immune System

Our immune system can be altered by the diet we take, naturally occurring food chemicals and environmental pollutants. One of the major pharmacological effects of flavonoids is their capacity to affect inflammatory processes and functions of the immune system. Ultimately, bioflavonoids are immune boosters and are regarded as health-promoting or disease-preventing dietary compounds. They possess antioxidant, anti-inflammatory, antiviral, and anti-allergic activities that function together for the body's adequate biological activities.

 

Sources of Bioflavonoids

Flavonoids can be easily obtained from our diets because they are the most common and widely distributed group of plant phenolics. Their sources include fruit skins, red wine, buckwheat, red pepper, and tomato skin, onion, olive oil, berries, and grapefruit, cherry, raspberry, and strawberry, citrus fruits, grapefruits, lemons, and oranges, soybean, and tea.

 

Conclusion

Bioflavonoids are essential for our body as they equip us with the right biological compounds for maintaining appropriate immunity.
