The role of color in plum nutrition
Plums, like many fruits, get their vibrant hues from natural compounds called phytochemicals. One key group of these compounds is flavonoids, which includes anthocyanins and phenolic compounds. The intensity and type of these flavonoids largely dictate the plum's color and its antioxidant potential. As a general rule, the darker the pigment, the higher the concentration of anthocyanins, which are potent antioxidants that help protect the body from cell damage caused by free radicals.
Beyond color, all plums are a good source of important nutrients, including:
- Dietary fiber: Aids in digestion and promotes a feeling of fullness.
- Vitamins: Rich in Vitamin C for immune support, Vitamin K for blood clotting and bone health, and Vitamin A for vision.
- Minerals: Contains potassium for blood pressure regulation, as well as magnesium and phosphorus.
- Sorbitol: A natural sugar alcohol that acts as a mild laxative, especially prevalent in dried plums (prunes).
Dark purple and black plums: The antioxidant champions
When considering what color plum is the healthiest for antioxidant content, dark purple and black plums are typically the winners. Varieties like 'Black Beauty' and 'Friar' plums are celebrated for their deep color and rich antioxidant profile. These fruits contain high levels of anthocyanins, which have been linked to several health benefits, including supporting heart health and potentially regulating blood sugar. Some standout varieties, like the Australian Queen Garnet plum, are specifically bred for their exceptionally high anthocyanin content.
Benefits of dark plums
- Enhanced antioxidant activity: High phenolic content provides a strong defense against oxidative stress.
- Heart health support: The anthocyanins help lower inflammation and may improve cardiovascular health.
- Supports immune function: A good source of Vitamin C, bolstering the body's defenses.
- Digestive regularity: Like other plums, they contain fiber and sorbitol to aid digestion.
Red plums: A balanced and heart-healthy choice
Red plums have a reddish skin and often yellow or reddish flesh. While not as high in anthocyanins as their darker counterparts, they still offer a significant dose, along with other beneficial compounds. Red plums are known for a slightly tart flavor, making them a popular choice for fresh snacking and salads.
Benefits of red plums
- Brain health: Some studies suggest that the anti-inflammatory compounds in red plums can support brain health.
- Immune booster: Rich in Vitamin C to help the immune system function optimally.
- Anti-inflammatory: Contain compounds that can help reduce inflammation throughout the body.
Yellow and green plums: Mild flavor, big health benefits
Yellow plums, such as Mirabelles, and green varieties, like Green Gages, have milder, sweeter flavors and golden or yellow skin. While they don't contain the anthocyanins of their darker relatives, they are still nutrient-dense and offer distinct health advantages. These varieties are often milder in taste and ideal for those who prefer less tartness.
Benefits of yellow and green plums
- Diuretic effect: Yellow plums can help eliminate excess fluids from the body.
- Rich in vitamins: A good source of vitamins C and E, both of which possess antioxidant properties.
- Versatile for cooking: Their milder flavor makes them perfect for jams, sauces, and baking.
A special mention: The Kakadu plum
For those seeking an absolute powerhouse of nutrition, the native Australian Kakadu plum is in a league of its own. It holds the world record for the highest concentration of natural Vitamin C, with up to 100 times more than an orange. While its availability is limited, it is a noteworthy example of the incredible nutritional variation within the plum family.

The verdict: Choosing the healthiest plum
Ultimately, there is no single "healthiest" plum, as all varieties are packed with valuable nutrients. The best choice depends on your specific nutritional goals and taste preferences. If your aim is to maximize antioxidant intake, particularly anthocyanins, reach for the deep purple or black varieties. If heart health is a primary focus, red plums with their inflammation-fighting compounds are an excellent option.

The important takeaway is to incorporate a variety of colorful fruits into your diet. This approach ensures you benefit from a wide spectrum of nutrients and health-boosting compounds.
