Ambrosio is a big fan of avocado toast for breakfast, and sometimes includes eggs and a green juice. "Avocados are high in fat with 60 percent of this being monounsaturated fats, which research suggests helps to protect against heart disease and lower blood pressure," says registered nutritionist Jo Lewin. "They are also an excellent source of potassium, folate and fiber, all of which benefit the heart and cardiovascular system."

Ambrosio likes a big salad for lunch, with chicken or fish as the added protein. She also keeps nuts or a protein bar in her purse in case of a snack emergency. "New research suggests that eating plenty of nitrate-rich vegetables — such as lettuce, spinach, and beets — may lower your risk of dying of a stroke or heart attack," says Harvard Health.

"I would say [I work out] an hour to an hour and a half a day," Ambrosio says. "It all depends on what I'm doing that day. If I'm going on a hike or playing volleyball with my friends it might be longer but I don't usually spend more than an hour and a half in the gym. I love to do different classes and lately I have been doing Tracy Anderson Method because it's fun and it feels more like a dance class than a work-out. But, at the same time, it's great exercise as it targets all muscle groups."

Ambrosio drinks green tea throughout the day, which experts say has incredible health benefits. "Green tea contains a number of natural stimulants, including caffeine, which although not as high as coffee, may still help maintain alertness and focus," says registered nutritionist Jo Lewin. "In addition to this, green tea is a source of the amino acid L-theanine, which has a relaxing effect; it does this by increasing mood-enhancing brain chemicals including GABA, dopamine and serotonin. The beneficial polyphenols of green tea may also help slow the effects of aging on the brain."

Ambrosio is a big fan of the beach—both for relaxing and for getting active. "Whenever I'm in Los Angeles, I like to go to Malibu—I'll get together with my friends and play volleyball," she tells VOGUE. "I always bring coconut water, nuts, and kale chips. For my kids, it's sunblock, sunblock, and sunblock. They go in and out of the water the whole day, so I make sure to reapply SPF 50 as much as possible. Make sure to moisturize and hydrate while you're at the beach, so when you are ready to go to dinner, you can just add some tinted moisturizer."
