The Greek physician Hippocrates, often referred to as the “Father of Medicine,” said “let food be your medicine.” The philosophy behind is focused on prevention. The huge wave that started during the 1990s in the United States has drastically changed the market trends for nutraceuticals. Consumers have started subscribing to diet regimens that reduce the risk of chronic diseases. People are using nutraceuticals and functional foods more for prevention than for the cure of diseases. After the industrial and communication revolutions, the lifestyles of humans are changing significantly. Everyone feels the scarcity of time, whether a young child or a retired adult. Earlier it was normal for a person to walk regularly a few miles; now lifestyles have changed, and there are fewer opportunities for people to walk or take regular exercise. Everyone is looking for alternative ways to keep healthy and trying to change their current lifestyles, leading to much healthier lifestyles. This is very well reflected in the growth of the nutraceutical and functional food market in the past decade. The growth of the nutraceutical food market from 2007 to 2013 was almost 142%, while that of nutraceutical supplements is estimated to increase by 125%, and nutraceutical beverages may increase by a whopping 185%. The nutraceutical market is predicted to record a revenue of USD 671.30 billion by 2024. Developing countries have a high prevalence of noncommunicable diseases like cancer, diabetes, cardiovascular ailments, etc. Therefore, the demand for nutraceuticals is expected to rise in these nations. The gradually increasing healthcare expenses are also stimulating the demand for nutraceuticals.
