When it comes to aging gracefully, most of us know the usual tips—exercise regularly, get enough sleep, and eat a healthy diet.
But according to new research, one unassuming snack might hold surprising power to support healthy aging at the cellular level.
And chances are, you’ve had it in your pantry for years.
A new study found that regularly eating a handful of plain, skin-on peanuts may help protect your DNA from the wear and tear of time.
But there’s a catch—not all peanut products seem to have the same effect.
Why telomeres matter as we age
At the ends of each chromosome are telomeres—tiny protective caps that help keep your DNA intact.
Think of them like the tips of shoelaces that prevent fraying.
As we grow older, these telomeres naturally get shorter, and when they become too short, cells struggle to divide and function properly.
This cellular aging process is linked to several chronic conditions, including heart disease, diabetes, and certain cancers.
Lifestyle factors like stress, sleep, and nutrition can all influence how fast this process unfolds.

What the new peanut study found
A team of Spanish researchers recruited 58 healthy young adults and divided them into three groups to test peanut-based snacks.
After three months, only the group eating whole peanuts showed a significant increase in telomere length.
None of them experienced accelerated shortening.
In contrast, 22% of the peanut butter group saw their telomeres shrink faster.

Why whole peanuts make a difference
Peanuts with skins contain antioxidants like vitamin E, niacin, and polyphenols, which help protect the body from damage caused by free radicals.
These nutrients support a healthier inflammatory response and may help slow aging at the cellular level.
Peanuts may also benefit gut health—participants who ate whole peanuts had higher levels of short-chain fatty acids in their gut, which are linked to better mood and lower stress.
Peanut butter, especially processed types, often contains added sugars and oils that may cancel out some of those benefits.

A warning for those with peanut allergies
Unfortunately, peanuts aren’t safe for everyone.
Over six million Americans are allergic to peanuts, and even small traces can be dangerous.
If you’re among them, don’t worry—other tree nuts like almonds and walnuts may offer similar benefits.
Still, more research is needed to determine their exact effects on telomeres.

Important caveats to keep in mind
The study was small, short-term, and limited to healthy young adults, so it’s not yet clear how these findings apply to older individuals.
Telomere changes typically happen slowly, over many years.
In addition, the study didn’t include a completely peanut-free control group, so it’s hard to say for certain if peanuts were the only factor in telomere length improvements.
Still, the results are promising enough to warrant further investigation.

Other health benefits of peanuts
Peanuts have been linked to reduced belly fat, better insulin regulation, and heart health support.
They’re rich in protein, fiber, and healthy fats, making them a filling and heart-smart snack.
But not all peanuts are created equal—some brands add extra salt, sugar, and oils that reduce their nutritional value.
Look for plain, dry-roasted peanuts with their skins and no added ingredients.

Simple ways to eat more peanuts
If you want to start incorporating peanuts into your routine, here are a few ideas:
Stick to about 25 grams (roughly one ounce) per day to avoid overdoing it on calories.
While there’s no miracle food to stop the clock, studies like this one highlight the powerful role everyday choices can play in how we age.
Choosing simple, whole foods like peanuts may offer small but meaningful benefits—not just for your cells, but for your overall well-being.
If you’re already enjoying a nutty snack each day, you might be giving your body a quiet advantage.
And if you’re new to peanuts, it could be worth a try!

A team of Spanish researchers recruited 58 healthy young adults and divided them into three groups to test peanut-based snacks.
- Group 1 ate 25 grams (about a small handful) of roasted peanuts with their skins.
- Group 2 ate 32 grams of peanut butter.
- Group 3 consumed a control butter made from peanut oil.
After three months, only the group eating whole peanuts showed a significant increase in telomere length.
None of them experienced accelerated shortening.
In contrast, 22% of the peanut butter group saw their telomeres shrink faster.
