How eating turkey can slow the hands of time

Whether it's the buckle in your knees when you get up from a chair... or that strange pull in your lower back when you bend down to tie your shoes... you can only ignore getting older for so long.

Even if you look "good for your age" -- and FEEL pretty good too -- there are changes happening inside your body that you can't see.

But don't despair, because a new study shows that you may be able to slow down the aging process -- just by eating turkey!

In a study published in a recent issue of Nature Communications, scientists from Spain treated mice with a condition known as "mitochondrial myopathy" -- which causes damage to the nerve cells in your brain and muscles, and can lead to everything from muscle weakness to heart failure and dementia.

The theory was that these signs of aging were associated with declining levels of an enzyme called NADPH, which tends to plummet as you get older -- and that slowing down that decline would likewise slow down the aging process.

So, the researchers genetically altered the mice to be able to produce large amounts of NADPH, and the results were amazing.

The genetically-altered rodents remained quick and well-coordinated as they aged... and the females lived 14 percent longer than their NADPH-deficient counterparts.

Considering the short lifespan of a mouse, that's a pretty long time.

And you know what's been shown to increase your levels of NADPH (or, at least, keep it from taking a nose-dive)?

Vitamin B3, a.k.a. niacin.

None of this comes as a surprise to me, knowing how this miracle vitamin can protect your nerves from damage related to chemotherapy drugs that destroy ALL cells -- cancerous and non-cancerous -- in their wake.

Since you're not a mouse... and you're not going to get genetically engineered in a lab... you don't need help from a team of researchers to boost your B3 and keep the signs of old age at bay.

If you're a fan of the Paleo diet as I am -- and as you should be -- you may ALREADY be on your way to getting the amounts you need to live better and longer.

Your body converts the amino acid tryptophan into B3, so you can bolster your B3 levels -- and keep your NADPH levels from dropping -- by enjoying Paleo-friendly, tryptophan-rich foods like turkey and other poultry, red meat, eggs, and dairy.

Feel free to add more B3-rich foods like peas, mushrooms, and avocado to your diet as well. And don't forget the nuts and seeds -- like peanuts and sunflower seeds -- which are bursting with it, too.

You can also get B3 as part of a B complex vitamin supplement -- but beware of the "niacin flush" that may occur. It's generally harmless, but it can be a little uncomfortable for some people.
