If only it were that simple. Consider the lifestyles. If you're willing to live the same lifestyle and same environmental conditions, the same diet variables could potentially lead to similar lifespan.

But in lieu of the same conditions, the logic to consume same diet isn't that sound.

I think the inspiration one should take from their grandparents and further back, is to avoid over-processed foods and highly refined foods.

They didn't eat ready-made processed meals loaded with salt and sugar, they didn't drink soda except on rare occasions, they didn't eat nearly the same amount of candy that we do today.

I'm only 33 and from my childhood I remember soda as a rare treat that was saved for birthdays and other special occasions, or if my dad and I had been working in the garden or on a DIY project. Very few things are more satisfying than a well-deserved ice-cold sugary fizzy drink while taking a break from hard work.

Soda was a luxury we didn't get every day, and 25cl was the standard serving size. Anything smaller than a 33cl can seems to be exceedingly rare now, and usually people go for the 50+cl bottles.

Our habits are completely out of whack.
