It was followed by a Materialism which had Pearson correlation value of 0.260 and significance value of 0.000. Then comes Low Nutritional Food being Pearson correlation value of 0.258 and significance value of 0.000. Testing of hypothesis found that television advertising increases the consumption of food that is unhealthy, having low nutritional values and high in Sugar, Fat and Salt (SFS) in children with F=30.146 & P=0.000.
