The Secret to a Long and Healthy Life

The idea that what a person eats influences their health no doubt predates any historical accounts that remain today. But, as is often the case for any scientific discipline, the first detailed accounts come from Ancient Greece. Hippocrates, one of the first physicians to claim diseases were natural and not supernatural, observed that many ailments were associated with gluttony; obese Greeks tended to die younger than slim Greeks, that was clear and written down on papyrus.

Spreading from this epicentre of science, these ideas were adopted and adapted over the centuries. And at the end of the 15th Century, Alvise Cornaro, an infirm aristocrat from a small village near Venice in Italy, turned the prevailing wisdom on its head, and on himself.

If indulgence was harmful, would dietary asceticism be helpful? To find out, Cornaro, aged 40, ate only 350g (12oz) of food per day, roughly 1000 calories according to recent estimates. He ate bread, panatela or broth, and eggs. For meat he chose veal, goat, beef, partridge, thrush, and any poultry that was available. He bought fish caught from the local rivers.

Restricted in amount but not variety, Cornaro claimed to have achieved “perfect health” up until his death more than 40 years later. Although he changed his birthdate as he aged, claiming that he had reached his 98th year, it is thought that he was around 84 when he died – still an impressive feat in the 16th Century, a time when 50 or 60 years old was considered elderly. In 1591, his grandson published his posthumous three-volume tome entitled “Discourses on the Sober Life,” pushing dietary restriction into the mainstream, and redefining ageing itself.

PS: My concern about a lot of the animal studies cited in this sort of research is that the the anti aging effects seem to flow from the delaying of puberty in the experimental animals.

They say runners need flexibility, but you may be surprised at the latest thinking

For years, runners have believed that their sport makes them too tight and that they should turn to yoga to lengthen their muscles, become more flexible and thereby develop into better runners. It turns out, though, that the opposite may be true: Coaches and physical therapists now say that bending like Gumby may, in fact, cause problems.

“When it comes to running, flexibility is overrated,” says Steve Magness, author of “The Science of Running” and cross country coach at the University of Houston. “Research shows that if you are too flexible, you are a less efficient runner.”

As Magness explains it, our muscles and tendons are designed like springs. As our feet hit the ground during a run, those springs release stored energy and propel us forward. If the springs aren’t tight enough, they can’t do their jobs properly.

Some research has touched on this in the past, but the idea that tightness can help runners is getting a new look in this era of yoga popularity. A 2010 study of eight distance runners looked at their overall running economy relative to flexibility.

The participants performed the classic “sit and reach” test before running, and their oxygen uptake was assessed. “We saw that those who were most flexible were the least efficient,” says Tamra Llewellyn, an assistant professor of health and human performance at Nebraska Wesleyan University and a co-author of the study. “Those with lower flexibility had greater elastic energy storage in their muscles and didn’t use as much oxygen.” In other words, their muscles could do more with less, allowing them to get more out of each stride at a lower level of exertion. 

Yet the perception persists that more flexibility — even as much as that of a yogi — is better for runners. “It’s a myth we’ll probably fight forever,” Magness says. “We’re all taught from a young age to stretch to improve flexibility and performance.”
