A well-balanced diet that includes a wide variety of fruits and vegetables, as well as the proper amount of macronutrients, is essential for a healthy body. However, these essential elements may be deficient in our diets on occasion. Insufficient nutrition may cause oxidative stress, which in turn can cause a variety of health problems.

New discoveries and cutting-edge technology are continually being made in nutrition research. Nutraceuticals are an example of a new breakthrough that combines nutrition and medicine.

​

What Is a Nutraceutical?
Nutritional and medical advantages may be found in nutraceuticals, which are products obtained from dietary sources.
Other names for nutraceuticals include:

• Nutritional supplements • Phytochemicals • Medicinal foods • Functional foods • Medical foods

Supplements, diets, herbal goods, genetically modified foods, and vitamins all fall under this category. In addition, they have a high concentration of bioactive substances that originate from a natural source and are beneficial to the body's physiology and the prevention and treatment of illness.

Prebiotics, probiotics, fortified foods, and drinks are all included in the category of nutraceuticals since they are commonplace in our daily diets.

As a rule of thumb, a nutraceutical is any chemical that has a beneficial effect on the body or prevents chronic illness.

Nutraceuticals are defined differently in different countries because of the way they are classified and controlled. Currently, there is no universally agreed-upon definition of what constitutes a nutraceutical.
Dietary supplements like nutraceuticals may help people live longer and stay healthy by slowing down or preventing the onset of chronic illnesses, improving cognitive function, or supporting the body's structure and function.

Additionally, they are used in the treatment and prevention of mental health concerns and disorders.

 

History
A nutraceutical was first used in 1989 by Stephen DeFelice, founder and chairman of the Cranford, New Jersey-based Foundation for Innovation in Medicine.
Food or components of food that give medicinal or health advantages including prevention and treatment of illness are characterized by DeFelice as "nutraceuticals" by DeFelice.

In many ancient societies, the notion of utilizing food as both a source of sustenance and a medicine has been widely accepted. Nutraceuticals have been around for a long time, dating back over 3,000 years. When Hippocrates, the founder of modern medicine, started to discover the link between diet and health, it began to take on.

People in India and China traditionally eat natural foods that are thought to be therapeutic, such as fruits and vegetables. Dietary considerations were considered more significant than exercise and inherited variables in people's quest for good health in countries like Germany, France, and England.

To this day, the effectiveness and safety of nutraceuticals are supported by data, fresh research, and ever-evolving technology, despite their traditional roots.

An Overview of the Functions of Nutraceuticals
Dietary fiber, vitamins, and minerals help your body repair, develop, and operate properly, all of which are essential for good health. Nutraceuticals may be used as a supplement when your diet doesn't include enough of these critical elements and vitamins.

Nutraceuticals, Metabolism, and Nutrients

Food is made up of nutrients, which are the chemical components. In order to maintain a healthy metabolism, a variety of nutrients, such as vitamins, water, electrolytes, and minerals, are required.

In order to transform our food into energy, our bodies utilise all chemical processes that take place in our bodies. This energy is then used to manufacture the molecules that our cells require. All cells and organs are kept alive by the processes of metabolism.

Metabolic pathways are influenced by the nutrients that are broken down. Our bodies, including our organs and systems, work well if all nutrients are present in the correct amounts. Meaning your body is capable of repairing itself rapidly and effectively.

However, your body may take longer to heal or you may have hazardous problems if you don't get enough nutrients. When this occurs, nutraceuticals may help your body get the additional nutrients it needs to perform at its best.

​

Types
There are many different types of nutraceuticals, each with a specific purpose, food source, and bioactive components that make them unique. Dietary supplements and functional foods make up the majority of them.

​

Supplements for the Diet
Concentrated bioactive components extracted from a food source and processed into an appropriate dose form constitute dietary supplements. Amino acids, vitamins, botanicals, minerals, essential metabolites, and specific enzymes are just a few of the ingredients that may be found in these supplements.

Gummies, energy bars, powders, and liquids are just a few of the many different varieties of dietary supplements.

In addition to providing a nutritional boost, dietary supplements may also help prevent and treat illness.

​

Foods with a Purpose
Anything that delivers a health advantage other than basic nourishment is referred to as a "functional food."

Whole foods, as well as fortified, enriched, or enhanced foods, fall under this category since they have the potential to benefit health when included frequently in a diverse diet. A wide variety of functional foods are accessible in a wide variety of forms.
