Economic development of the people has improved their lifestyle. But the challenge that has arisen with this lifestyle change is increasing the prevalence of ‘lifestyle diseases.’ Lifestyle diseases refers to diseases associated with bad lifestyle choices including food habits. The increased trend of eating junk food is known to be the reason for several diseases (obesity, cardiovascular diseases) and nutritional deficiencies. Due to high cost of treatment of these diseases in the modern science, people have started looking for alternative or complementary treatment options. Thus, nutraceuticals came into focus and are being opted as they fulfill nutritional requirements and have therapeutic benefits.
The word “nutraceutical” was coined from “nutrition” and “pharmaceutical” by Stephen De Felice, founder and chairman of the Foundation for Innovation in Medicine in 1989. It is defined as “a food or parts of food that provide medical or health benefits, including the prevention and treatment of disease”. Nutraceuticals are the pharmaceutically blended products that have both nutritional as well as the medicinal value. This type of product is designed to improve the physical health, and fight against day-to-day challenges such as stress, increase longevity, etc. It is a food supplement that plays a vital role in maintaining a healthy body and provides necessary supplements required for various metabolic processes to regulate body functions and thus protects the body from disease.
According to a Mordor Intelligence Report, the global nutraceuticals market is predicted to reach $671.30 billion by 2024.
