2. Lack of Magnesium
This is an essential mineral, however many of us have inadequate amounts of magnesium. According to the Connective Tissue Disorder Site (CTDS), low magnesium can cause facial tics in children. These facial tics can be a sign of Tourette syndrome in some cases.
However, by changing your diet to include more magnesium (or taking quality supplements) you can alleviate some of these symptoms, according to the CTDS. Foods that contain magnesium naturally include almonds, sunflower seeds, and certain beans. If you’re giving your child a lot of milk, the calcium content must be balanced with magnesium for optimal health and absorption.
