Here is some information about the types of food being advertised to your children.
There is a great deal of studies and evidence that shows that the foods marketed to children are not the nutrient dense foods (foods high in vitamins and minerals) but instead, the calorie dense foods (foods that have very little nutrition but high in fat and/or sugar).
Go, slow and whoa foods* are:
Go foods are foods that are high in nutrients and should be eaten every day. These are foods from the five groups: fruits, vegetables, low fat or fat-free no sugar-added dairy, healthy lean proteins and whole grains
Slow foods are foods that you should eat only a few times a week, not every day. These foods have nutrition but tend to be higher in sugar and fat. Examples of slow foods would be refined flour products, 2% milk, 100% fruit juice, peanut butter or Canadian bacon.
Whoa foods are foods that are mainly sugar and/or fat foods with very little, if any, nutritional value, like cake, cookies, candy, potato chips and soda. These foods should be eaten only once in a while.
