Kate Walsh shares self-care regimen after undergoing surgery to remove brain tumor

"I'm always keeping inflammation low," she explained.

Now Walsh, 50, is prioritizing herself and encouraging other women to prioritize their health.

"You can never talk too much about how important it is for women to be proactive about their health," she told ABC News.

Walsh said that now her trick to self-care involves lots and lots of water.

"I walk around with this giant water bottle," the actress said. "It's a half-gallon. So if I make it through one of these a day, I'm doing great."

"I'm always keeping inflammation low," she explained of her additions.

Along with keeping a diet high in good fats and protein -- "tons of veggies," she said -- Walsh loves walking. In fact, it's one of the reasons why she moved back to New York, she said.

But just because she's focused on her health doesn't mean she doesn't splurge sometimes.

"I'm not going to stay away from my potato chips and by the way I love regular Doritos," she gushed. "I like the orange powder."
