Research suggests that compounds in meat may trigger wheezing in some children, which can lead to asthma or other respiratory problems. These compounds, known as advanced glycation end products, are released when meat is grilled at high temperatures. So eating a vegetarian diet or eating less meat can protect children from asthma risk.
Meat roasting without high temperature does not produce advanced glycation end products, and its association with asthma is unknown most questions the above statement.
