A recent study conducted by the Hyderabad-based ICMR-National Institute of Nutrition has revealed that frequent consumption of ultra-processed foods (UPFs) such as packaged snacks, sugary drinks, biscuits, and instant foods may significantly increase the risk of high blood pressure among urban youth.
Study Details and Findings
The study, published in the journal 'Nutrients', analyzed dietary patterns and blood pressure profiles of 311 undergraduate students aged 18 to 24 from colleges in Hyderabad. The researchers discovered that students who consumed higher amounts of high-fat and high-salt ultra-processed foods had nearly three times higher odds of elevated blood pressure compared to those with lower intake.
Notably, 12.5% of the participants already had elevated blood pressure levels of 140/90 mmHg or above, indicating an emerging cardiovascular risk among young adults. Commonly consumed ultra-processed foods among participants included biscuits, chocolates, packaged savory snacks, bread products, sugary beverages, and instant foods.
Reasons for High Consumption
Scientists identified taste, convenience, affordability, and easy availability as the major reasons driving increased consumption of ultra-processed foods among urban youth. The study noted that the association between UPF intake and elevated blood pressure remained significant even after adjusting for factors such as age, sex, residence, and family income.
Methodology and Expert Comments
Researchers used a detailed food survey based on the NOVA classification system to study how often participants consumed 24 commonly eaten ultra-processed foods. Blood pressure levels were measured using standard medical procedures.
Lead authors Dr. Karthikeyan S and Dr. Samarasimha Reddy emphasized that the growing dependence on packaged and convenience foods among urban youth requires urgent public health attention. They stated, "There need to be targeted interventions in colleges and universities to encourage healthier dietary choices and improve awareness about the health risks associated with excessive ultra-processed food consumption."
Dr. Bharati Kulkarni, Director of NIN, commented, "India is witnessing a rapid nutrition transition, particularly among adolescents and young adults," and stressed the need to strengthen nutrition literacy and create healthier food environments.
