Depending on the genes you were dealt, your body could be destined for a long, healthy future that stretches on for decades to come.
Of course, your fate isn’t etched in stone. The diet you eat – and the way you eat it – could determine just how many of those prescribed days will be seen in good constitution.
Gerontologist Valter Longo from the University of Southern California in the US is convinced there’s an optimal formula to fasting and dieting that could give us the best chance of maximizing our individual lifespans.
To work out what that formula might look like, Longo and his colleague Rozalyn Anderson of the University of Wisconsin explored the literature on longevity and nutrition in a variety of living things, relating it all back to our own species.
“We explored the link between nutrients, fasting, genes, and longevity in short-lived species, and connected these links to clinical and epidemiological studies in primates and humans – including centenarians,” says Longo.
Of course, a single prescribed method of eating isn’t likely to ever become a one-size-fits-all approach. Just as variations in food habits introduce a litany of pros and cons for the health of other species, from simple microbes to worms to mammals like us, our own differences in genes and stages of development will determine the risks and benefits of different food items.
People older than 65, for example, might need to add a little more protein in their diet, just to ensure their bodies have plenty of material to bulk up dropping body mass and guard against growing frailty.
