Published in the Critical Reviews in Food Science and Nutrition journal, this study demonstrates that current vitamin C recommended daily allowances (RDAs) are inadequate for people with higher body weights. Lead researcher Professor Anitra Carr from the University of Otago, Christchurch, New Zealand, emphasizes that current guidelines, based on the needs of a healthy 70-kilogram male, do not account for the increased requirements of heavier individuals, thus leaving a significant portion of the global population underserved.
The study, which analyzed data from the United States National Health and Nutrition Examination Survey and the European Prospective Investigation into Cancer-Norfolk study, found that only about two-thirds of participants met adequate vitamin C levels with the existing RDAs. This discrepancy is particularly pronounced among heavier individuals due to the effects of obesity on vitamin C metabolism, including increased oxidative stress and inflammation.
To address this gap, Professor Carr recommends updating the vitamin C RDAs globally. With scientific evidence clearly now linking optimum vitamin C levels to the prevention of chronic diseases such as heart disease and cancer, the study underscores the urgent need for public health guidelines to be revised.
