In 2024, there was a significant surge in awareness regarding nutrition, as individuals became increasingly conscious of their dietary habits and lifestyle choices. Recognizing that each person has unique nutritional needs, it is essential to customize diets accordingly. A novel approach to nutrition has emerged, gaining widespread acceptance.

Nutrigenomics, which examines the interplay between genes, nutrition, and health, focuses on how these elements work together to enhance well-being. In a discussion with Lifestyle, Dt. Vaishali Verma, Consultant in Nutrition and Dietetics at Manipal Hospital Dwarka in New Delhi, stated, “This field integrates nutrition with an individual’s genetic makeup, facilitating personalized eating habits tailored to their genetic profile and promoting effective strategies for achieving overall health.”

What is nutrigenomics?

The field of nutrigenomics seeks to clarify the connection between genetic factors and the nutritional composition of our diets. This understanding can enhance dietary choices by assessing how individual bodies respond to different foods through genetic analysis, as articulated by Dt. Vaishali Verma.

Furthermore, Dr V Mohan, Chairman of Dr Mohan's Diabetes Specialities Centre in Chennai, remarked, "The emergence of continuous glucose monitoring systems has significantly advanced precision nutrition. Current knowledge indicates that identical foods can elicit varying responses in different individuals."

Advantages of nutrigenomics?

Enhanced nutrient absorption: Individuals will be able to pinpoint the genes influencing nutrient uptake and subsequently focus on metabolic processes to optimize the benefits derived from food.

Chronic disease prevention: This approach will tailor an individual's diet to mitigate genetic predispositions that may lead to conditions such as diabetes, cardiovascular diseases, and obesity.

Promotion of mental well-being: It will facilitate an understanding of how genetic makeup impacts emotions and stress levels, allowing for adjustments in dietary habits to improve overall mental health.

How has nutrigenomics redefined the nutrition landscape?

Enhanced health outcomes: A tailored approach to nutrition that addresses the unique requirements of each individual can effectively prevent chronic illnesses, facilitate weight management, and enhance overall health. For example, nutrigenomics can identify pre-existing genetic factors that influence inflammation, gut motility, and food metabolism, thereby assisting in the management of conditions such as Irritable Bowel Syndrome (IBS). Personalized dietary plans can promote gut health by addressing specific issues, including food intolerances or allergies.

Improved dietary guidance: Customized meal plans are more likely to be adhered to, as they take into account personal preferences and lifestyle choices.

Informed decision-making: Individuals are empowered to make informed choices regarding their health by concentrating on their specific health needs.
