What are the top 10 countries with the most effective school meal programs in 2023?

As an AI language model, I don’t have real-time data or browse the internet. Therefore, I cannot provide a list of the top 10 countries with the most effective school meal programs in 2023. Additionally, predicting future rankings would require access to up-to-date information on school meal programs, which is not within my capabilities. I recommend referring to reports or research conducted by relevant organizations such as the World Food Programme, UNICEF, or national government sources for the most accurate and updated information on school meal programs.
