Serena Williams is the exception to the rule of stereotypical pregnancy cravings. Ice cream, potato chips, and pickles aren’t the mainstay items on her shopping list—in fact, as she awaits the arrival of her bundle of joy, she’s drooling over some of the healthiest picks around.

The pro tennis legend is expected to have her first child within the next month, and amid the final countdown, her fiancé, Alexis Ohanian, is making a strong case for Dad of the Year by volunteering for late-night snack duty.

During a recent trip to the grocery store, the Reddit co-founder posted an Instagram video in which he shared exactly what Williams is craving.

“It’s a Friday night and I’m at Publix going shopping ’cause my fiancé has cravings,” says Ohanian in the video. “I was told there would be cravings. I was not told they would be these. Zucchini, asparagus and…what’s this one called again? Artichoke. There we go. Really? These are her cravings. It’s amazing.”

So what’s the deal with these healthy prenatal snacks? According to Vicki Shanta Retelny, RDN, it’s not shocking for someone as health-minded as Williams to ply her little bambino with nutrient-rich fuel.

“Craving healthy foods during pregnancy can stem from a heightened awareness of how food choices affect you and your baby,” she says. “It’s no longer just the woman’s needs, but her growing belly reminds her of the need to amp up the produce, protein and healthy fats, such as omega-3 fats, in her diet.”
