I was browsing through the USDA Food Search system for data on various foods, when I noticed they include how much of a food is water. What really perplexed me is how 81.1 grams out of 100g of russet potato is water… when 88.1g of 100g of milk is also stated as water.
Obviously a potato isn’t liquid like milk, and my intuition would say that 100g of potatoes seem far denser and “drier” than 100g of milk. I mean can you imagine sating your thirst with just solid potatoes, as opposed to say a glass of milk?
But yet I can’t make sense of why one is solid and the other is liquid when they’re nearly the same in water content, or why one would seem to sate thirst more.
Bonus question: does this mean you poop about as much from 100g of milk as you would from 100g of, potatoes? I guess you could blend the potatoes…
