When it comes to easing stress through food, oranges may not be the first thing that comes to mind—but they should be. According to registered dietitian Kristen Lorenz, oranges are packed with key nutrients that support both the immune system and the body’s stress response.

Oranges are rich in vitamin C, which boosts immune function by supporting white blood cells and protecting them from damage. This matters because stress and immunity are closely connected: a strong immune system can better manage inflammation caused by stress, while chronic stress and elevated cortisol can weaken immune defenses.

Beyond vitamin C, oranges also contain flavonoids—antioxidants with anti-inflammatory benefits—and B vitamins like folate, which help regulate mood by aiding neurotransmitter production. Even magnesium, found in small amounts in oranges, plays a role in calming the nervous system.

Oranges offer other perks, too. Their fiber supports gut health, while potassium helps regulate blood pressure. Plus, with 86% water content, oranges help keep you hydrated—another important factor in managing stress.

While other citrus fruits like grapefruit, lemons, and limes may contain more vitamin C by weight, oranges stand out for their taste and versatility. They’re easy to eat and enjoyable, making them a practical choice for everyday stress relief.

Want to eat more oranges? Try adding them to smoothies with banana and vanilla, layering them in a yogurt parfait, tossing them into a fresh salad with avocado and greens, or roasting slices with honey for a caramelized treat. For a savory twist, use them in salsas or pair with grilled meats.
