Generally, when there are tics, Sec IgA is low. When low, it can cause stress in the
GI tract and the tics are a result of partially digested food finding their way into the blood stream. Alternately, if Sec IgA is too high, it could indicate a chronic infection.
To increase Sec IgA: Remove offending foods- processed foods, starches, sugar and eat whole foods that you find along the perimeter of the foodstore.
