EPA: Research on the Impact of Diet on Cardiovascular Responses to Air Pollution

Recent Environmental Protection Agency (EPA) research is exploring how diet, which can influence physiology and health in both overt and subtle ways, can shape our body’s response to air pollution.

In a study published in Environmental Science & Technology in 2018, results showed the potential effects of early life vitamin D deficiency on cardiopulmonary responses to atmospheric smog air pollution in mice. Vitamin D is produced in the skin through exposure to sunlight, as well as through diet, and it contributes to the maintenance of normal function of numerous organ systems, including the cardiovascular system. The study found that chronic vitamin D deficiency can cause subtle latent changes in the body, which might increase the risk of an adverse response to a stressor like air pollution.
