My Opinion
I strongly disagree that silver leaf decorations should be in indian sweets. There are more negatives to that side than positives. It can cause health issues, environmental issues, damages to the body such as death. Even though it looks appealing on indian sweets, luxury, expensive, and its has a wide industrial use. I believe that the diseases are a bigger part of a person surviving life rather eating.

Colour : makes the sweets look more appealing.

Texture: adds to the grace and makes it easier to spread over the sweets.

Malleability: enables the slices densed, shiny and saves metal.

Lustre: shows the beautiness of the decorations on the sweets to make them look delightful.
Reaction with the air: The silver leaf are made out of metal and does not lose lustre in pure air. The leaves have silver also included which doesn't react with water or air. Even though its silver it can get rusty which isn't a good thing.

Toxicity: Most components of the leaves have taken in toxic like aluminium, silver and cadmium. If it is toxic not only its added on the sweets. People who eat it will get infected with really serious diseases such as death.
