The most recent Daily Sun article I could find was Nov. 2011 by Dr. David Lipschitz. The Heading: "Data looking ironclad that supplements harm"
I'll try to give some of the highlights:
Older people may get too much iron because 1) fortification of food and 2) nutritional supplements containing iron. (not to mention the iron that comes from eating red meat)
This may cause an increased risk of cancer, heart disease and Alzheimer's. Because iron is an oxidant, it can lead to cell damage.

Question: How can vitamins shorten life expectancy?
Possible explanation: Vitamin supplements are too unlike vitamins and minerals found in food.
Conclusion: The best source for vitamins and minerals comes from eating food.
I found about 4 other articles warning about vitamins but I'm not sure I want to take the time to summarize all of them. It's very time consuming.
