The health benefits of plums include relief from indigestion, influenza infections, weight loss, and anxiety-related problems. The antioxidant power of these fruits helps in preventing and managing osteoporosis, macular degeneration, cancer, diabetes, and obesity. They also help in maintaining a healthy heart by reducing cholesterol levels. Additionally, plums improve cognition, boost immunity, improve cellular health, maintain electrolyte balance, keep the nervous system healthy, and aid in skin care and blood clotting.
What are Plums?
They are juicy and delicious fruits that belong to the genus Prunus of the Rosaceae family which also includes peaches, apricots, and nectarines. They exist in diverse colors and shapes with over 2000 different varieties. Plums are broadly divided into three groups: European-Asian (Prunus domestica), Japanese (Prunus salicina) and Damson (Prunus insititia). China is the leading harvester of plums, followed by the United States, Serbia, and Romania. Within the US, the major production of plums happens in California.
They are small deciduous trees that grow to a height of about 10-15 meters and bear fruits with different characteristics based on the country of origin. They are drupes or stone fruits with a smooth pit and a crease running down on one side. They contain juicy pulp varying from creamy yellow to crimson red. The color of the outer skin may vary considerably from yellow or dark red to purple or black.
Nutritional Value of Plums
Plums contain an assortment of healthy components, vitamins, and minerals. According to the USDA National Nutrient Database, they are an excellent source of vitamins such as vitamin A, vitamin C (ascorbic acid), folate, and vitamin K (phylloquinone). [4] They are also a good source of vitamin B1 (thiamine), B2 (riboflavin), B3 (niacin), B-6, and vitamin E (alpha-tocopherol). The minerals present in them include potassium, fluoride, phosphorus, magnesium, iron, calcium, and zinc. They also supply dietary fiber and offer very low calories without any harmful fats.
Health Benefits of Plums
They are packed with an immense range of phenols and flavonoids, which offer an impressive range of health benefits.
Antioxidant Properties
These fruits contain vitamin C and phytonutrients such as lutein, cryptoxanthin, zeaxanthin, neochlorogenic acid, and chlorogenic acid. These components possess effective antioxidant qualities that help in preventing the damage caused by oxygen radicals called superoxide anion radicals. A study published in the Journal of Medicinal Food, by researchers in France, concluded that the phenols present in plums also extend their protective effect on the essential fats in the neurons and cell membranes against any injuries caused by oxidative stress.
Manages Diabetes
Plums exert anti-hyperglycemic effects and help in combating diabetes. A study published in the journal Biomedical Research in 2005 has shown that consumption of plum extracts aids in reducing blood sugar and triglyceride levels in the body. The flavonoids present in plums exert protective effects against insulin resistance and help to enhance insulin sensitivity in the body.
Prevent Osteoporosis
Consumption of dried plums exerts anabolic and anti-resorptive actions, which aid in maintaining healthy bones. Polyphenols, along with the potassium content present in dried plums, encourage the formation of bones, improve bone density, and prevent bone loss caused by ovarian hormone deficiency. Dr. Bernard P Halloran conducted a research study, published in the Journal of Nutrition, which demonstrated that regular consumption of dried plums helps in the restoration of bone density that has already been lost due to aging.
Aid in Digestion
They are a good source of dietary fiber, along with the components sorbitol and isatin, which help in regulating the digestive system. According to a research study conducted by Dr. Attaluri A, University of Iowa Carver College of Medicine, USA, published in the Alimentary Pharmacology and Therapeutics Journal, dried plums or prunes are more effective in treating digestive disorders such as constipation as compared to other remedies such as psyllium husk.
Healthy Nervous System
Plums contain vitamin B6, which helps in the transmission of nerve signals and aids in the smooth functioning of the nervous system. They also help in the normal growth of the brain and assist in the formation of mood influencing hormones. Tryptophan, an amino acid present in them, helps in the production of the neurotransmitter serotonin, which plays an important role in improving sleep, appetite, and concentration.
Protect Heart Health
Researchers from the Department of Food Science and Nutrition, University of Minnesota, USA, has provided supporting evidence regarding the fact that the regular intake of dried plums helps in promoting fluidity of blood in the arteries. This protective effect aids in the prevention of various cardiac disorders, including atherosclerosis, heart attack, and stroke.
Boost Immunity
Plums are beneficial in strengthening the immune defense of the body due to the presence of high vitamin C content. This vitamin promotes the body’s resistance to infections and inflammations. Research has shown that oriental plums have immunostimulatory constituents that encourage the production of nitric oxide in the body, impede the metastasis of tumor cells, and are valuable in preventing various diseases.
Regulate Cholesterol Levels
Dried plums or prunes help in preventing hypercholesterolemia and hyperlipidemia. A comparative study by the researchers at the Department of Nutrition, University of California, USA, has proven the efficacy of prunes over grape-juice in maintaining healthy levels of plasma and liver cholesterol. The fiber content present in them also adds to the protective effect of the heart by reducing LDL or bad cholesterol and helping to elevate the levels of HDL or good cholesterol.
Anticancer Potential
Plum extracts have been proven beneficial in the treatment of cancer. Studies conducted and published by Dr. Lavanya Reddivari, Dr. Venkata Charepalli, et al, Department of Plant Science, The Pennsylvania State University, USA, have shown that the component epicatechin, present in plums, helps in inhibiting the growth and proliferation of malignant cancer cells and induces apoptosis in human hepatocellular carcinoma or liver cancer.
Skin Care
They are rich in vitamin C, along with other antioxidants, which help maintain healthy, radiant, and youthful skin. The consumption of plums helps in reducing dark spots and wrinkles due to the presence of anti-aging nutrients. Plum extracts are also used in various skin care products such as face wash and face packs.
Culinary Use
They are widely used in food items due to their sweet and tart flavor, as well as their pleasant aroma. They can be enjoyed fresh and can also be added to puddings, jams, and jellies. Plum juice is used in the preparation of alcoholic beverages. Prune juice concentrate works deliciously well as a filling for candies and confectionery products, and as a binding agent for cereal bars. Plum chutney or dip is famous in Indian cuisine and is served along with stuffed Indian bread. It is also relished as a condiment along with the meat delicacies.
