wherein the nanobubble water contains bubbles with a modal particle size of from 30 to 300 nm,
wherein the nanobubble water contains the bubbles in an amount of from 1×108 to 1×1010 bubbles/mL, and
wherein the bubbles contained in the nanobubble water include i) air or ii) oxygen having a concentration higher than a concentration of oxygen in the air.
