NASA did not invent enriched baby food. However, NASA has contributed to advancements in food technology for space missions, including creating nutrient-rich foods that are easy to prepare and consume in microgravity environments. This research has also benefited nutrition and food science on Earth.
So far as I know, no foods as such were *invented*. But I think they pioneered freeze drying and irradiation.
