A previous study showed that 80% of the nutrients were still in the soup residue, and only 20% was in the soup, so drinking soup didn't have much effect.

In fact, this statement is not very clear, because it is simpler and more direct for our body to absorb nutrients from liquid, which involves the problem of absorption rate. Because the nutrition in the soup is more easily absorbed by the body, there will be an illusion that the soup is more nutritious.

However, from the perspective of absorption rate, this statement is not wrong.
