Are there big studies that link diet and lifestyle choices with the probability of reaching a certain age? What are their conclusions?

There are either too many possible answers, or good answers would be too long for this format. Please add details to narrow the answer set or to isolate an issue that can be answered in a few paragraphs.If this question can be reworded to fit the rules in the help center, please edit the question.

Where have you looked so far? –  kmm Dec 21 '12 at 20:40
This would seem to be the sort of question that gets whole books written about it. Please can you narrow it down a bit? Or rather, can you narrow it down a lot? –  EnergyNumbers Dec 24 '12 at 12:41

Many such studies have been conducted to a limited extent in human populations for specific endpoints: for example, using the "Mediterranean diet" will statistically expose you to a lower risk of cardiovascular mortality. Exercising regularly will also have that effect. Basically, every big prevention message modern medicine sends at the population level (don't smoke, don't drink, etc.) is geared towards a longer life, and is supported by literature.

If you want examples, just head over to Pubmed.

However, if you want something more specific about life expectancy, you will have to look at animal research. Well known experiments conducted on D. melanogaster and monkeys raised interesting conclusions:

  • reproducing late in life (if you can call that a lifestyle choice...) will raise the life expectancy of subsequent generations.
  • however, it will also decrease the fertility of subsequent generations

We can draw an interesting parallel with the present situation in humans, as we tend to reproduce later than in the old days, life expectancy tends to increase, and there are a lot of infertility problems. However, there is no literature to support that those aspects are linked in humans (to my knowledge).
