The Big Mac is a sandwich sold by the international fast-food chain McDonald's.

Products from companies like Biocare are catching popularity very fast. I think there are two reasons why people are so much after multivitamins and food supplements. One, they are rich in nutritional value. Secondly, they are easy to consume.

The fast-food chain is rolling out packaging that lets you know the nutritional value of that Big Mac. Will consumers bite?
