Health benefits of Plums
1. Memory enhancer
Eating plums (75 mg/kg) helps in enhancing memory. As it contains large amounts of polyphenols and phytochemicals like Neochlorogenic acid, chlorogenic acid, crypto chlorogenic acid, caffeic acid, anthocyanins, flavanols and flavonoids (4).
2. Prevents obesity
Plum juice is rich in dietary polyphenols and also carbohydrate free. Therefore it helps in modifying the fecal bacterial composition thus decreases the body weight (5)
High antioxidant activity of fresh and dried plums are because of anthocyanins, flavonoid and phenolic compounds such as chlorogenic acid, neochlorogenic acid, caffeic acid, coumaric acid, rutin and proanthocyanidin (6).
Consumption of plum decreases blood glucose and plasma triglyceride. As it contains chlorogenic acid which may lower the risk of type 2 diabetes (7).
5. Healthy Bones
Dried plum is rich in minerals like boron, copper, magnesium, and manganese which help in maintaining the calcium balance of the body (8). Thus significantly increases the bone mineral density of ulna and spine in comparison with dried apples and prevent osteoporosis in postmenopausal women (9).
Plims act as a natural laxative because of polyphenols, dietary fibers, and sorbitol. Hence eating plums is helpful in mild constipation (10).
7. Improve digestion
Carotenoids and polyphenols found in plums reduced gastrointestinal inflammation and stimulated digestion (11).

11. Treats anxiety disorder

Dietary fiber and polyphenols mainly chlorogenic and neo-chlorogenic acids in plums helps in lowering colon and breast cancer risk (16).
13. Prevents age-related cognitive disease

Difference between Plum and Prune
Prunes are the dried fruits of some cultivars of plums. It contains concentrated source nutritive, laxative and digestive compounds. Hence used for the treatment of hypertension, diabetes, jaundice, and fever. Plums are healthier than prunes. As prunes are dried out by different techniques which produce detrimental effects on the quality of fruits, mainly oxidative damage, browning, loss of flavor and extensive shrinkage, which reduce the sensory and nutritional quality of the products. Therefore consuming plums instead of prunes are good for health (19).
