Food companies as we said before will not stop selling highly processed food with cheap raw ingredients plus preservatives and coloring agents that just make it looks healthier and last longer and seems attractive to consumers.
Billions of dollars are spent every year in marketing campaigns of processed food. And the more time our children spend in front of screens or even attracted to those kinds of food while shopping with their parents the more likely they are exposed to those kinds of food.
So why don't we launch a counter marketing campaign. you parents can try to make home made food more flashy and colorful, mothers can teach their children to grow plant for example at home or in a garden nearby and then eat the product together later with your children. Lets make it funny and try to make designs with fruits and vegetables to attract children. And always try to limit you children exposure to ads of processed food.
