Historically:
* Before widespread school lunch programs: Many children brought their own lunches from home, often consisting of whatever their families could afford. This could range from simple sandwiches and fruits to leftovers. Many children didn't have lunches at all.
* Early school lunch programs (mid-20th century): These programs were often simpler, focusing on basic nutrition. Think things like milk, bread, and perhaps a simple stew or soup. The quality and variety varied greatly depending on funding and resources.
Currently (in many developed countries):
* School lunches provided by the school: These vary considerably, but generally aim to meet nutritional guidelines. They often include:
* Main course: This might be a hot meal like pasta, chicken, or vegetarian options.
* Sides: Vegetables, fruits, and sometimes grains.
* Dairy: Milk or yogurt.
* Packed lunches: Children still often bring their own lunches, which can range widely in quality and nutritional value. Popular items include:
* Sandwiches
* Fruits and vegetables
* Chips/crisps (though these are often discouraged)
* Yogurt
* Juice boxes/water bottles
* Sweets/desserts (often limited or restricted)
Developing Countries:
School lunches in developing countries can be very different, often reflecting the local food culture and economic realities. Some schools may have little or no formal lunch program, while others may provide a simple meal, potentially focused on locally sourced grains or vegetables.
In short, there's no single answer. The school lunch experience is incredibly diverse and shaped by numerous factors.
