The Big Picture
If you approach your training program from a long term perspective, focusing on improved athletic performance will ultimately lead you to an overall improved health profile. If you are looking here for tips on improving your athletic performance, then you likely have an interest in keeping that athletic performance as high as you can for as long as possible. The best way to achieve that is to give your body the best possible building blocks that will not only allow you to get the most out of your training program, but to keep an optimal baseline of health into what has been known in previous generations as the "Golden Years".
People now looking at what were traditionally retirement years now can expect 20, 30 or even more years beyond the once-geriatric age of 65. The question anymore isn't so much "how long will I live", but more along the lines of "what's is my quality of life going to be like when I'm 75, 85 or 95 years old?" The same principles used in providing a nutritional base for improving athletic performance will also provide an excellent nutritional base for keeping bones strong, maintaining muscle strength, and developing intellectually.
