cucumber
The answer is cucumber. It’s more than 90% water, and while it’s not that it has no nutrients, its key point is being low in calories.

See the answer
spiciness

While metallic taste is not classified as one of the basic tastes, it is a distinctive sensation sometimes experienced when metal touches the inside of the mouth and is occasionally considered within the broader scope of taste. Therefore, “spiciness” is not included among the human tastes, making it the correct answer.
