I guess that's without taking into account eating tons meat to recover through Life Return.
Life return is one of the most busted abilities in this series.
I guess the milk drinking healing their teeth is, technically Life Return too.
I wonder if Lilith will realize how important food is to Luffy, and make the most nutrient dense, possible food for him to use life return with.
Meat is obviously very nutritious. Look at how much it's contributed to human civilization and animals in general. A bear didn't get that big from the berries.
But scientifically speaking, it really isn't the most nutrient dense food.
And there's no reason to believe that the modern food is comparable to what was available in the ancient kingdom.
The ancient kingdom probably had much more advanced, much healthier food. Food is medicine is an old proverb in many civilizations.
Haki is found in all living things. The reason eating fresh meat probably powers Luffy up is the Haki is still fresh in the flesh.
Lilith finding a food source much more dense than meat, and better tasting than meat, could honestly make him a vegetarian. If Lilith was able to produce artificial meat that was healthier and tastier than regular meat, Luffy would probably become a vegetarian.
I feel like this is hinted at a few times.
"Yeah, but, now that I'm friends with those guys... I can't eat em anymore. And they look so tasty..."
"ANYONE WHO BECOMES MY FRIEND IS OFF THE MENU!!"
I've seen a lot of people say that one of Luffy's power ups is going to be food related. It's gonna be interesting to see if Vegapunk is involved in it.
Maybe Lilith making the Soda is foreshadowing this?
Like what happens if Gear 5 Luffy drinks this Soda?
I really think everyone on the Straw Hats is getting a power up in this arc.
