How it works:
Hot foods poured into plastic packets for home delivery can cause microscopic melting of the plastic. The melted plastic releases compounds called "plasticizers" into the hot food. These plasticizers are eaten by us along with the food we eat. Since these are small compounds, our intestine absorbs them and takes them into our blood stream. These compounds pass through the blood vessels and get clogged in the "end arteries" of the eye. They clog into the end arteries of the eye because these vessels are really tiny and do not let these compounds flow through.
These clogged blood vessels cause waste materials to accumulate in the retina and degeneration sets in. This causes classical Age Related Macular Degeneration to occur in relatively younger persons.
Plasticizers also cause male sterility. (Other disadvantages of food delivered in plastic packs).
Lot of medical journals have studied and reported this occurrence. But of late, these articles have started disappearing form literature presumably due to pressure form the plastic industry in the US.
What you can do:
Avoid putting hot food into plastic containers. Use steel vessels instead.
