Thought I need to agree food is not.
Anyways two or three cokes a week won't hurt.
Drinking Daily coffee won't hurt.
Eating at McDonalds or BurgerKing twice a week won't hurt.
If you do sports twice a week. (And eat some Vitamins, but that is usually no problem I believe.)
But obviously it depends on how active you are, plus I don't think it's up to the supermarket to ensure that people eat healthily.
As a european living in the US, I am appalled at the sheer quantity of vitamins/pseudo health products that my roommates consume. Do you really need this? I don't know a single person in France who takes vitamins on regular basis.
If you sit on your pc in your office or at home, and have bowl of fruits next to you, you'll eat one or 2 per day and then you got ALL vitamins you need.
I would argue that 6 x 30mins is the minimum and mcdonalds should be once a month, not twice a week.
And skip the vitamins.
The fact you think in any shape or form vitamins have a relevance to you shows you have a total miss understanding of food science and how it relates to you.
Unless you are starving because of drought in a poor country or are living on the streets with an addiction, then fair enough.
The problem I see is that there are two terms of "healthy" food that people tend to confuse.
1) Food that makes you Overweight 2) Food that does not have specific oils/ Vitamins.
Apologys for not writing clearly there, I tried to make the point that you usually don't need to care about Vitamins.
