Daily Prunes May Help Protect Your Bones
New research points to a simple habit with potential upside for bone health: eating prunes every day. The effect appears especially relevant for younger women who may experience the downsides of oral contraceptives on bone. A steady, daily serving of prunes over the course of a year emerged as a practical way to help curb bone loss.
What the Study Found About Bone Density
The study observed a meaningful rise in bone mineral density at the ultradistal radius among women aged 18 to 25 who were taking oral contraceptives and ate 50 grams of prunes each day. That region is vulnerable because of its trabecular structure, and even small changes there can matter for overall bone strength.
Why Trabecular Bone Matters
Trabecular bone forms a three-dimensional, lattice-like network that helps bones absorb force and stay strong. Its architecture, however, also makes it more prone to fractures. For younger women whose bone density can dip due to hormonal effects tied to contraceptive use, supporting this type of bone is especially important.
How Prunes May Work
Researchers are still clarifying the “why,” but one leading idea is that prunes help by dialing down bone resorption—the process where specialized cells called osteoclasts break down bone tissue. With less breakdown, bone can better maintain its integrity over time.
What’s Inside a Prune
Prunes contain a mix of minerals, vitamin K, and fiber—nutrients that support healthy bones. As Dr. Shirin Hooshmand of San Diego State University, who led the research, emphasized, these components play a meaningful role in maintaining bone strength.
Oral Contraceptives and Bone Health
Health data point to a worrying pattern among women aged 15 to 44 who use oral contraception, with nearly 25% reporting osteoporosis-related issues. Consistent OC use can signal the need to be proactive with diet choices that support bone vitality—daily prunes can be one of those choices.
Building on What We Already Know
This work adds to prior findings on prunes and bone health. Earlier research, including the Prune Study in postmenopausal women, also linked daily prune intake with bone benefits. Taken together, the evidence suggests prunes may be useful across different life stages.
Simple Ways to Eat More Prunes
California Prunes bring both flavor and function to the table, which makes them easy to put to use day after day. Their naturally sweet, rich taste plays well in a wide range of dishes, from bright and fresh to deep and savory.
Recipes to Try with California Prunes
Here are a few easy ideas that highlight how versatile prunes can be:
- Whipped Feta Dip: Blend feta until smooth, fold in pureed prunes, and serve with crisp bell peppers or crunchy crackers. The prunes add a gentle sweetness that balances the tang.
- Roasted Cauliflower Dish: Toss cauliflower with prunes, olives, and sun-dried tomatoes, then roast until caramelized. The mix of savory, sweet, and briny flavors makes an eye-catching side.
- Farro Salad: Combine farro with chopped prunes, fresh herbs, and a zesty vinaigrette. It travels well and holds up on a potluck table.
About the California Prune Board
Established in 1952, the California Prune Board represents prune growers and handlers across the state, widely recognized for producing prunes of exceptional quality. The Board’s work centers on health and wellness, backed by rigorous food safety standards, so consumers can count on products that meet a high bar.
Frequently Asked Questions
How can prunes support bone health?
Daily prunes help maintain bone density by supporting bone-preserving processes and limiting bone breakdown, which is particularly relevant for women using oral contraceptives.
What’s a practical daily amount?
About 50 grams per day—roughly a handful—is the amount associated with the bone benefits described in the research.
Do prunes fit into everyday meals?
Yes. They’re easy to add to both sweet and savory dishes, and the recipes above are a simple place to start.
Are there any downsides to watch for?
Prunes are generally well tolerated. That said, eating too many may cause digestive discomfort for some people.
What does the California Prune Board do?
It supports California prune growers and handlers and promotes prunes’ quality and nutrition, while aligning with strict food safety practices.
