Inside Out •Ruby red grapefruit is winter’s feel-good citrus fruit.

With its vibrant color and tangy-sweet flavor, ruby red grapefruit brightens up your winter diet—and your overall health.

This blushing citrus superstar packs in vitamins A and C—plus powerful lycopene—making this nutrient-dense grapefruit an antioxidant superhero. But ruby red grapefruit’s health-boosting benefits go way beyond that. Here’s how the pretty, puckery fruit can make you glow from head to toe.

Hydrates the body

With its high water content (nearly 4 ounces per halfgrapefruit), ruby red rocks as a thirst quencher. Juice it for a fresh drink or to add zing to seafood recipes.

Controls appetite

As a fiber-rich food with high water content, grapefruit keeps you satiated. Half a grapefruit contains 52 calories and 2 grams of fiber. Nosh on fresh segments or toss them in a salad.

Brightens skin

Grapefruit’s antioxidants help protect against cell damage, increase collagen production and improve skin tone.

Fights illness

Bursting with potassium, folate, thiamine and magnesium and a hefty dose of vitamins A and C—28% and 64% of daily value per half-fruit, respectively—grapefruit’s nutrients can boost immunity. And its bright red flesh packs in lycopene, a potential protector against viruses, cancer, diabetes and heart disease.

Maintains eye health

The antioxidant-rich fruit is high in a flavonoid called naringin, which could play a critical role in eye health by helping to prevent cataracts, age-related macular degeneration and other eye disorders.
