Food waste is a global issue with serious economic, social, and environmental consequences. According to the FAO, one-third of global food production is lost every year. That’s why adults at home play a key role—and have a great opportunity—to educate children in the fight against this problem by promoting sustainable habits and values such as empathy and respect for resources.
A Family System to Prevent Food Waste
The first step is education, and the best way to teach is through experience, curiosity, and leading by example. Once children understand the issue, we can actively involve them in practical solutions at home. Here are some ideas:
1. Include children in menu planning
By involving them in family meal planning, they’ll learn the importance of eating a varied, nutritious, and balanced diet. Using a family calendar with drawings and stickers can make it fun for younger kids.
2. Make the shopping list together
Before going shopping, check the fridge and pantry with them so they learn to identify which foods are missing and which can still be used. This reduces unnecessary purchases and gives them a sense of responsibility.
3. Cook as a family
This is one of the most educational and fun activities you can do at home. Assign tasks based on their age: washing vegetables, measuring ingredients, mixing dough, etc. While cooking, you can talk to them about how to use leftovers or turn simple ingredients into different dishes. Plus, if they’ve helped prepare the meal, they’re more likely to finish their food.
4. Serve appropriate portions
A common form of waste is serving more than can be eaten. Teach children to serve small portions with the option to have seconds if they’re still hungry. You can even turn it into a game to see who can clean their plate without wasting food.
5. Making the Most of Leftovers — Nothing Goes to Waste
Teach the “3Rs” rule.
- Reuse: Properly store leftovers for another meal.
- Reinvent: Turn leftovers into new dishes.
- Redistribute: If you know you won’t eat something, share it with guests, family, or freeze it for later.
6. Create a “best before” food corner
It’s important for them to learn about expiration dates and “best before” labels, as well as to eat the ripest fruits and vegetables first. Set up a visible space in the kitchen or fridge for foods that are close to expiring. Involving them in tracking these items improves planning and builds a responsible sense of urgency.
