Chia seeds have a single nutrition, and should be combined with vegetables, fruits, fish and eggs to meet the body’s nutritional needs. Although chia seeds have been recognized by the European Food Safety Authority as a food that does not cause allergies, it cannot be ruled out that some people with special health conditions may experience allergic reactions after consumption, such as itchy skin, sneezing, and runny nose, so they should be consumed with caution.
