The terms "nutrition" and "pharmaceutical" are combined to form the term "nutritraceutical." In general, nutraceuticals are foods or dietary components that significantly contribute to regulating and preserving the regular physiological processes that keep people healthy. The present demographic and health trends are the main drivers of the global nutraceutical market's growth. Dietary fibre, probiotics, prebiotics, polyunsaturated fatty acids, antioxidants, and other herbal/natural food products can all be classified as nutraceuticals. These nutraceuticals aid in the fight against some of the century's biggest health issues, including diabetes, cholesterol, osteoporosis, cancer, cardiovascular disease, and obesity. Overall, "nutraceuticals" have ushered in a new era of health and medicine, where the food industry is now a research-focused field.
