What Do Plums Do for the Human Body?

3 min read

According to a review of 54 studies, plums and plum-derived products may help lower the risk of certain cancers, suggesting a powerful protective effect. But what do plums do for the human body on a day-to-day basis? This humble fruit is packed with antioxidants, fiber, and essential nutrients that offer wide-ranging health benefits, from improving digestion to supporting heart health and more.

Quick Summary

Plums are a nutrient-dense fruit rich in antioxidants, fiber, and vitamins that aid digestion, boost heart health, and promote stronger bones. They help stabilize blood sugar levels and possess anti-inflammatory properties that combat chronic disease.

Key Points

  • Supports Digestive Health: Plums and prunes contain fiber and sorbitol, acting as a natural laxative to relieve constipation and regulate bowel movements.

  • Rich in Antioxidants: High levels of polyphenols and anthocyanins in plums combat oxidative stress and reduce inflammation, protecting against cell damage.

  • Boosts Heart Health: The potassium and fiber in plums help manage blood pressure and cholesterol levels, supporting overall cardiovascular function.

  • Strengthens Bones: Nutrients like vitamin K and potassium, especially concentrated in prunes, have been linked to improved bone mineral density.

  • Helps Regulate Blood Sugar: With a low glycemic index and high fiber content, plums help stabilize blood sugar levels and may improve insulin sensitivity.

  • Aids in Weight Management: Low in calories and high in fiber, plums promote satiety and can help curb appetite, supporting weight loss goals.

  • Enhances Skin and Immune Health: Vitamin C and antioxidants in plums boost the immune system and promote collagen production for healthier skin.

A Powerhouse of Antioxidants

Plums and their dried counterpart, prunes, are particularly rich in antioxidants that fight cellular damage caused by free radicals. This antioxidant capacity is largely attributed to their high concentration of polyphenols, with anthocyanins being the most active, especially in the dark-skinned varieties. By combating oxidative stress, plums can help reduce inflammation and lower the risk of several chronic diseases, including certain cancers and heart conditions.

How Antioxidants Protect Your Body

Antioxidants are crucial for maintaining overall health. They work by neutralizing unstable molecules called free radicals, which can damage cells and contribute to aging and disease. The antioxidants found in plums, such as vitamin C and various phenolic compounds, perform several protective functions:

  • Cellular Defense: They shield cells and tissues from oxidative damage, a process that can accelerate aging and lead to chronic illness.
  • Anti-Inflammatory Action: Plums have been shown to have anti-inflammatory properties that can help prevent diseases associated with excessive inflammation.
  • Cardiovascular Support: By protecting LDL ("bad") cholesterol from oxidation, plums contribute to improved heart health.

Digestive Health Champion

Plums, particularly when dried into prunes, are a well-known remedy for digestive issues due to their high fiber content and the presence of sorbitol, a natural sugar alcohol. The fiber adds bulk to stool, while sorbitol draws water into the colon, providing a natural laxative effect that helps regulate bowel movements and relieve constipation. This dual action makes them highly effective for maintaining a healthy and regular digestive system.

The Role of Fiber and Sorbitol

  • Fiber: Plums contain both soluble and insoluble fiber. Insoluble fiber promotes regularity by adding bulk, while soluble fiber slows digestion and helps regulate blood sugar.
  • Sorbitol: This natural compound found in prunes has a gentle laxative effect, which, along with the fiber, makes prunes more effective for constipation than many common laxatives.
  • Gut Microbiome: The prebiotic fiber in plums also feeds beneficial gut bacteria, which is essential for a healthy digestive system and overall wellness.

Potential for Stronger Bones

While more research is needed, studies, particularly on postmenopausal women, have shown promising links between prune consumption and improved bone mineral density. The exact mechanism is still under investigation, but it is believed that the antioxidants and anti-inflammatory properties of plums, along with key nutrients like vitamin K and potassium, play a significant role.

Comparison of Nutrients in Plums vs. Prunes (per 100g)

Nutrient Fresh Plums Dried Plums (Prunes)
Calories ~46 kcal ~224 kcal
Carbohydrates 11 g ~60 g
Fiber 1.4 g 7.1 g
Potassium 157 mg 732 mg
Vitamin K 4.2 mcg 59.5 mcg

Heart Health Support

Plums contribute to cardiovascular wellness by helping to manage major risk factors for heart disease, such as high blood pressure and cholesterol levels. Their rich supply of potassium helps regulate blood pressure by balancing sodium levels and easing tension in blood vessel walls. The fiber, meanwhile, helps lower LDL ("bad") cholesterol levels by binding to cholesterol and preventing its absorption.

Blood Sugar Management

Despite their sweet flavor, plums have a relatively low glycemic index, which means they don't cause a significant spike in blood sugar levels. This is largely due to their fiber content, which slows the rate at which carbohydrates are absorbed. Some studies also suggest plums may increase levels of adiponectin, a hormone that regulates blood sugar.

The Verdict on Plums

From boosting digestive health and protecting your heart to strengthening bones and managing blood sugar, plums and prunes offer a versatile array of health benefits. Their rich nutrient profile, packed with fiber, vitamins, and powerful antioxidants, makes them an excellent addition to a balanced diet. While moderation is key to avoid potential side effects like bloating, especially with prunes, enjoying this delicious fruit can have a significantly positive impact on your overall well-being.

Frequently Asked Questions

For most people, eating one to two fresh plums or 4-5 prunes per day is a reasonable amount that provides health benefits without causing digestive issues.

Prunes are dried plums and have a more concentrated nutrient profile, especially in fiber and sorbitol, making them more effective for treating constipation. While fresh plums offer great benefits, prunes contain higher amounts of the specific nutrients known to support bone health.

Yes, plums are generally considered a good fruit for people with diabetes when eaten in moderation. Their low glycemic index and fiber content help prevent rapid blood sugar spikes.

Yes, overconsumption of plums or prunes can lead to digestive discomfort such as bloating, gas, or diarrhea due to their high fiber and sorbitol content.

Plums benefit heart health through their potassium, fiber, and antioxidant content. Potassium helps regulate blood pressure, while fiber and antioxidants work to lower cholesterol and reduce inflammation, which are major risk factors for heart disease.

Plums can aid in weight management because they are low in calories and high in water and fiber. This combination helps you feel full longer, which can reduce overall calorie intake.

Individuals prone to kidney stones should be cautious with plums due to their oxalate content. Those taking blood thinners should also be mindful of their vitamin K intake from prunes and consult their doctor.
