Asthma is a serious health problem that is more prevalent among low income persons. Low dietary intake of protective nutrients, such as magnesium (Mg), and high intake of energy that results in overweight and obesity has the potential to increase the risk of asthma and worsen asthma symptoms. This study of people with asthma and healthy controls showed that total body Mg stores were negatively related to increasing weight as measured by body mass index (BMI). In all BMI groups the mean recommend dietary goal for Mg was below recommended levels. Replacing low Mg foods with high Mg foods may be a practical, low cost way to help reduce the risk of obesity and low Mg status in people with asthma, especially at risk low income groups.
