DSM highlights benefits of nutritional solutions to counter health impact of air pollution in new paper
In the ‘Global Update of Air Quality Guidelines (AQG)’, the World Health Organization (WHO) emphasizes that “clean air is considered to be a basic requirement of human health and wellbeing” (WHO 2005). According to the AQG, the recommended PM2.5 concentration, selected to minimize likely health effects based on existing literature, is an annual mean of 10μg/m3. The WHO also sets an annual mean of 35μg/m3 as an interim target-1 (IT-1), exposure to which is associated with an approximately 15% increase in mortality risk. It has been estimated that 80% of the world’s population lives in regions that exceed the AQG1 and it is a growing problem.
“Inhaling polluted air, especially air containing PM2.5, constitutes an environmental risk that has a proven impact on the quality and duration of human life,” said co-author Professor Manfred Eggersdorfer, Senior Vice President, Nutrition, Science & Advocacy at DSM and Professor for Healthy Ageing at Groningen University. He adds: “The objective of this scientific paper is to highlight human clinical investigations in which vitamins and marine-derived long-chain polyunsaturated fatty acids were administrated to significantly reduce certain detrimental responses to PM2.5 exposure.”
Results from both randomized and cohort studies in the last decade demonstrated that PM2.5 exposure induced unfavorable physiological and biochemical responses (i.e. heart rate variability reduction and oxidative stress) in the human body. Supplementation of fish oil, some B vitamins, vitamin E and C were shown to intervene with these responses.
Corresponding author, Weiguo Zhang, Director of Nutritional Science and Advocacy, DSM Nutritional Products, Human Nutrition & Science of Greater China, also comments: “Many people across the world are now exposed to air pollution daily. The studies included in this paper demonstrate that nutrition can play an important role in reducing some detrimental responses of the body to PM2.5 exposure. Future investigations are needed to determine whether long-term administration of these nutrients improves PM2.5-related clinical endpoints, for example, cardiovascular and respiratory outcomes.”

Vitamins in Motion
Vitamins play an essential role for health, wellness and disease prevention throughout the lifecycle. They are key to solving our global nutritional challenges. DSM, a global leader in health and nutrition science, is leading an initiative - Vitamins in Motion - to highlight the important role of vitamins. The campaign advocates for increased access, through innovative solutions, to the essential vitamins all people need to be healthy and well-nourished. To learn more, visit www.vitaminsinmotion.com.
