Cetirizine is an antihistamine used to relieve allergy symptoms such as watery eyes, runny nose, itching eyes/nose, sneezing, hives, and itching. It works by blocking a certain natural substance (histamine) that your body makes during an allergic reaction.
In general, a healthy breakfast contains protein, fruits, whole grains, or vegetables, says Ruth Frechman, MA, RDN, CPT, nutritionist and author of The Food is My Friend Diet.. Typically, you want to include foods from at least three of these groups, says Frechman.
The most important thing is to combine a lean source of protein with a healthy carb.
