How to improve the food and food education at a school

Many years ago i can almost remember on what the food was like in the school i attended. Now many years have gone passed and i now have a child who attends school and eats the food that schools are serving. She enjoys it, but i just say if there was a way, How could we improve the food and food education at our schools.
One way we can improve the food and food education in our schools is by having a spokesperson or a dietician to visit schools once a week and discuss what it is to eat healthy and whats not. Maybe she can mention to students who enjoy playing sports or any other recreation in school that keeping a healthy diet is very important for them. This diet can help them play more effectively and perform better in what they do. Such as, cheerleaders, basketball, track or any recreation in school. Keeping a healthy diet can help a child develop bones and eating habits.
Another way to help out our schools are to show them some consequenses. We can explain if they dont watch what their eating this can become a serious problem. Such as, obesity or illnesses in their future. We have children eating chips and soda all day from the vending machines on school premises. If your eating hamburgers and fries at school lunch everyday, this can cause for a student to become obese.
We can also have fundraising at our schools. We can have talent shows, sell candy and have bake sales, so we can raise enough money to feed our students better meals. We can serve healthy, natural grown food. Maybe we can sell only organics if possible. We can have a variety of food for our students to choose from. Knowing that what their choosing is much healthier.
Lastly, i would like to say by improving the food and food education at our schools can become a better influence on their choices when eating. This is why i commend this idea.
