The ongoing pandemic has brought in its wake the compulsory use of face masks. But there is a lot of confusion and controversy about the use and usefulness of face masks. The Center for Disease Control and Prevention (CDC), USA has recommended that even people who are healthy should wear masks over their mouths and noses when going out of their homes to places where social distancing is not possible. But there is a debate over the use of such masks, especially the homemade masks, as to whether the masks can slow down the spread of the corona virus. Most people agree, however, that wearing the mask might keep people infected with the viral disease from unknowingly passing the virus to another person.

As it turns out, though born of legitimate concerns, the impulse to discontinue gluten or dairy products is generally misguided, and may distract parents from truly important steps that can help kids to eat right, grow, and thrive.
