Fast food can affect the growth and development of children if consumed often. It can put children at greater risk of disease, according to Harvard Health.
Studies have linked fast food diets to increased risk of childhood diseases such as asthma, rhinitis and eczema, notes Harvard Health. It is also strongly linked to obesity.
Fast food consumed in childhood can also cause problems later in life. Foods high in sugar and fat are addictive, and when children develop the habit of consuming them it can lead to health problems later in life such as diabetes, high blood pressure and high cholesterol, according to the NourishLife.org.
