10 Proven Health Benefits of Plums (Backed by Science)
Plums are juicy, nutrient-dense fruits that may support digestion, heart health, and bone strength while providing powerful antioxidants. Backed by scientific research, they are a simple and delicious addition to any wellness-focused diet.
1. Supports Digestive Health
Plums and prunes are well-known for their natural ability to support healthy digestion. They contain dietary fiber, sorbitol (a natural sugar alcohol), and phenolic compounds, which collectively promote bowel regularity and help nourish the gut microbiome.
A clinical study published in Alimentary Pharmacology & Therapeutics found that prunes improved stool frequency and consistency more effectively than psyllium fiber in adults with mild constipation. This digestive benefit is linked to their combined content of soluble fiber and natural sorbitol, which softens stool and enhances motility.
Tip: Eating 2–3 fresh plums or 4–5 dried prunes daily may help maintain normal digestion and gut health.
