Boiling is used to enhance the texture of starchy foods and tougher proteins, making them more edible. It also revives grains, dried pasta, and dried legumes, making them soft and tender.
What are the effects of boiling?
When boiling occurs, the more energetic molecules change to a gas, spread out, and form bubbles. These rise to the surface and enter the atmosphere. It requires energy to change from a liquid to a gas (see enthalpy of vaporization). In addition, gas molecules leaving the liquid remove thermal energy from the liquid.

Why you shouldn’t boil vegetables?
Exposing vegetables to heat for too long. Doing so destroys the majority of vegetables’ nutrients. Boiling them is also a no-go.

To retain these vitamins, cook vegetables in as little water as possible for a minimal amount of time (unless you’re planning to consume the water, as in a soup). Steaming and microwaving, both of which use little water, will give you the same results as boiling or blanching but with much less nutrient loss.
Does boiling fruit destroy vitamins?
