11 Reasons To Love Plums

They can be easily transformed into sauces, jams and chutneys; they can also add a nice sweet touch to your meat dishes or turnovers. Plums, though, aren’t just a tasty treat whether eaten fresh or dried. They also offer a bevy of health-promoting properties that are hard to ignore.

Mounting research on plums shows promising outcomes on their anti-inflammatory, antioxidant and memory-improving qualities.[i] Researchers are particularly drawn to this fruit for its high phenolic content, primarily antioxidants called anthocyanins. Here’s a rundown of 11 reasons to love and eat plums with gusto today.

11 Top Health Benefits of Plums

  1. Promote Bone Health

Dried plum or prunes, scientifically known as Prunus domestica L., are believed to be effective in preventing and reversing bone loss.

To test this, researchers recruited 236 women, one to 10 years postmenopausal, to their study and found that dried plum significantly reduced the blood levels of bone turnover markers in the subjects.[ii] They concluded that dried plum can improve bone mineral density in postmenopausal women partly by suppressing the rate of bone turnover.

Similar findings on dried plums emerged in male animal models, where they increased bone mass, suppressed pro-inflammatory cytokines and promoted peak bone mass.[iii] They also prevented bone loss in a male osteoporosis model via varying pathways.[iv]

  1. Support Cognition

Consuming fruits and vegetables potentially protects against age-related cognitive decline, particularly when it comes to high-antioxidant produce. In a study on aging animal subjects, those that drank plum juice from 19 to 21 months of age showed improved working memory in an activity.[v] Those fed dried plum powder weren’t different from the control group, likely because of the smaller quantity of phenolics in the powder form.

  1. Relieve Constipation

Consuming prunes may effectively aid in treating constipation. People who ate 2 ounces or 50 grams of prunes daily for three weeks reported having better stool consistency as well as frequency versus the psyllium group.[vi]

Be careful, however, as consuming too many prunes may lead to unwanted effects, such as diarrhoea. Make sure, too, that there aren’t added sugars if you’re consuming prune juice for the bowel benefits.

  1. May Inhibit Breast Cancer

Previous studies highlighted plum’s anti-mutagenic effects. Researchers tested an acetone extract of immature Chinese plum fruit and found it offered higher levels of total phenolics and condensed tannins compared to mature plums.[vii]

The extract from immature fruit possessed cytotoxic effects, indicating potential to be a safe, promising dietary intervention against the development of breast cancer.

  1. Support Heart Health

In one study, participants drank prune juice and consumed three or six prunes every morning for eight weeks, or drank only a glass of water on an empty stomach.[viii] The prune and prune juice group experienced significantly lower blood pressure, total cholesterol and LDL cholesterol versus the water group.

In another study, men diagnosed with high cholesterol had lower LDL cholesterol levels after they consumed 12 prunes every day for eight weeks.[ix] In a separate study, consuming polyphenol-rich peach and plum juice prevented risk factors for obesity-related metabolic disorders as well as cardiovascular disease in animal models.[x]

  1. May Fight Liver Cancer

In a study published in 2009, immature plum extracts strongly inhibited cancer cell growth in HepG2 cells, which are implicated in liver cancer.[xi] Immature plum and its active compound, epicatechin, were deemed “a natural resource for developing novel therapeutic agents for cancer prevention and treatment” by the researchers.

  1. Antibacterial and Anti-Inflammatory Properties

Prunus domestica, in a study, demonstrated “remarkable power” in antibacterial tests, especially against Staphylococcus aureus and Escherichia coli, for two extracts studies.[xii]

A separate study assessed the antioxidant activity in plums that mediates its anti-inflammatory benefits, finding that chlorogenic acids were a major source of the antioxidant activity in the fruit.[xiii] Consuming fresh plums may be a challenge as they are seasonal, so converting the juice extract into powder is a common strategy.

Drying, however, may affect the polyphenols present and influence the various ways plum inhibits the growth of foodborne pathogens.[xiv] Plum extract powders, for instance, showed greater anti-inflammatory activity depending on the treatment and temperature used in the drying process.

  1. Lung Cancer Benefits

In probing the underlying effects of purified plum polyphenols on human lung cancer cells, scientists concluded that there is a potential for the polyphenols to be an effective dietary intervention for cancer or during chemotherapy.[xv]

  1. Weight Loss Support

In a study, researchers evaluated the effects of water-extracted plum on adiposity and inflammation in cells, analysing aspects such as total phenolic and flavonoid content along with antioxidant activity.[xvi]

Their results emphasized the potential for plum to be a natural agent in preventing and improving obesity. Snacking on dried plums may also increase satiety as well as decrease subsequent food intake, helping control obesity.[xvii]

  1. Maintain Blood Sugar

In vitro, animal and some human studies have highlighted functional foods’ ability to influence insulin resistance and underlying oxidative stress and inflammatory processes leading to diabetes. In a study, data indicated that a functional foods-based diet, including plums, may help manage Type 2 diabetes.[xviii] Plums also have the potential to increase levels of the hormone adiponectin, which plays a role in regulating blood sugar.[xix]

  1. May Combat Colon Cancer

Tested in vitro on colon cancer cells, a polyphenol-enriched plum extract inhibited the growth of cancer cells and attenuated cancer-induced cell damage.[xx] It also appears to protect muscle cells from tumour-induced cytotoxicity, the researchers wrote.
