On your first point, only if we can replicate the nutrients derived from the animal, then this would be a true production method of meat. McDonalds can culture its future grown beef and begin to make health claims, which is where I see grown meat being best suited, fast food and frozen foods as two that come to mind, where meat is altered to suit mass production. I hope rigorous studies are done to determine the health value of grown meat.
On your second point, that is the problem I fear. We are only now discovering en masse the health effects of the FDA Approved Diet that is based on 6-11 servings of grain/grain based products. So if the meat is released to the public it had better be under some intense scrutiny.
On the third and final point, I want world hunger to cease. If, sticking heavily on if, grown meat becomes viable and mass produced, I see three ways that it would reach these starving regions, it is provided in aid, it is sold to them, or they begin producing it themselves.
If provided as aid, it might feed them for the time they are provided the food, if it even reaches them. Over a long term, the people would be dependent on the food, especially if in a region beset in conflict, trapped in an environment disaster, or living in a refugee camp, as examples. This does not promote long term sustainability for the people being provided aid. In the short term, it is good to feed the starving, but as a long term, it leaves them dependent on foreign aid.
If sold, I doubt Africans who can only afford to purchase fish carcasses can afford laboratory grown meat exported from a foreign country, which leads into self-production, requiring a stable situation to support a massive food production effort like artificial meat. That kind of stability is usually found very rarely in the situations where wide spread starvation exists.
In the end, I think world hunger is better combated by attacking the causes of the hunger, not just treating the symptoms, though trying to end a civil war in another country is many magnitudes more difficult than feeding the refugees of the conflict. I would very much like for cheaper, less environmentally damaging food production to be available to all people of the world, that they can eat, live, and thrive. The problem as always, is with people, and no artificial fishstick is going to help.
