How A Healthy Diet Turned Johnathan's Life Around. 

Parts of his body are very weathered-looking, and he gets around extremely slowly, but after all, we're talking about a 183-year-old. His name is Jonathan, and he's been through a lot in life, including a serious this-could-be-the-end health scare after he lost his eyesight and ability to smell. But Jonathan, who happens to be a giant tortoise living on the south Atlantic island known as St. Helena, is still going strong.⁽¹⁾

So, what can be learned from this amazing creature? Turns out, a lot.
What turned his health around after his scare was the fact that he was put on a diet consisting of highly nutritious foods. Suggesting that the Seychelles tortoise eat from a bowl that included carrots, cucumber, bananas, lettuce, guava and apples – a far departure from Jonathan's previous selections of leaves, dirt and twigs.⁽¹⁾

Now lets think about this. If its good for Johnathan, then it is probably good for us.
