Eggs and milk are produced to be eaten (by the new organism) and are as close to "stuff produced to be eaten" that you get, perhaps. Super nutrient dense growth broths.
Seeds and legumes are meant to be eaten (by the new plant), but often have anti-plant-eater defenses (like cyanide), including in fruit. Eggs and milk do not seem to have such an analogue.
Fat stores are produced to be eaten (by the host itself), alas.
