I Added Prunes to My Diet for 14 Days – When I decided to eat prunes daily for two weeks, I’ll admit—I was skeptical. Sure, they’re often marketed as a digestive aid, but could these wrinkly little fruits really make a noticeable difference in my health? As someone navigating a wellness journey focused on improving digestion and supporting overall vitality, I wanted to see if prunes were more than just a remedy for occasional sluggishness.
Here’s how my prune experiment unfolded, complete with daily observations, expert insights, and some delicious ways to enjoy them.

Why Prunes? A Nutrition Breakdown
Before diving in, let’s talk numbers. Per 100 grams, prunes contain:
- 240 calories
- 0.4g fat
- 64g carbohydrates
- 7g fiber
- 38g natural sugars
- 2.2g protein
They’re also rich in vitamins like vitamin K and vitamin A, minerals like potassium and magnesium, and antioxidants like polyphenols. Registered dietitian Brandon Smith explains, “Prunes are a nutrient-dense fruit that pack a punch when it comes to supporting digestion, bone health, and blood sugar regulation. Their high fiber content and sorbitol—a natural sugar alcohol—make them particularly effective for gut health.”

With this info in mind, I committed to eating about four prunes (roughly 30 grams) daily for two weeks. Here’s what happened.
Day-by-Day Observations: The Good, the Surprising, and the Neutral
Benefit #1: Improved Digestion
By Day 3, I noticed something significant: my digestion felt smoother. No bloating, no sluggishness—just regularity. With 7 grams of fiber per 100 grams and natural sorbitol, prunes are a gentle yet effective way to keep things moving. “Their combination of soluble and insoluble fiber supports gut motility,” Brandon explained. For someone prone to occasional constipation, this was a welcome change.
Benefit #2: Stronger Bones

Around Day 7, I read up on prunes’ potential role in bone health. Research suggests that their vitamin K, potassium, and antioxidant content may help reduce bone loss and improve bone density. “Prunes are one of the few foods shown to positively impact bone health, especially in postmenopausal women,” Brandon noted. While I didn’t notice immediate effects, I appreciated knowing I was supporting long-term bone strength.
Benefit #3: Stabilized Blood Sugar Levels
This one surprised me most. On Day 10, I paired prunes with Greek yogurt for breakfast and noticed my post-meal glucose readings stayed steady. Despite their natural sugar content, prunes have a low glycemic index due to their fiber and sorbitol. “The fiber slows down sugar absorption, preventing sharp spikes,” Brandon said.

Benefit #4: Cholesterol Control
By Day 12, I wondered if prunes could impact heart health. Turns out, their fiber and antioxidant content can help lower LDL (“bad”) cholesterol levels. “The soluble fiber in prunes binds to cholesterol in the digestive tract, helping remove it from the body,” Brandon explained. While I didn’t measure my cholesterol during the two weeks, I felt good knowing I was doing something proactive for my heart.
Benefit #5: Sustained Energy Without Crashes
By the end of the two weeks, I felt steadier energy throughout the day. The natural sugars in prunes provided a gentle lift without the jittery crash I sometimes get from processed snacks. “Their mix of fiber, natural sugars, and micronutrients makes them an excellent choice for sustained energy,” Brandon added.
Limitations and Downsides
While my experience was largely positive, there were a few caveats. First, their natural sugar content adds up quickly. Eating too many prunes (say, more than six daily) could lead to excess calorie or sugar intake, especially for those managing diabetes. Stick to a small serving—about four prunes—to avoid overdoing it.
Second, their laxative effect can be too strong for some people. On a couple of occasions, I ate five prunes in one sitting and felt mild discomfort. Brandon warned, “Start small and increase gradually to avoid digestive distress.”
Lastly, while they’re nutrient-dense, prunes shouldn’t replace other whole foods entirely. Balance is key—they’re best enjoyed as part of a varied diet.
