Stoessel is an incredible dancer, no surprise to anyone who has attended her performances. "Dance, both in the Olympics and in life, seem to be under-recognized and under-appreciated in its potential benefits for health and mental health," says H. Steven Moffic, MD. "Finally, however, the benefits of dancing are being scientifically researched. Benefits from a variety of studies involve our hearts, lungs, bones, and brains… Rhythmic dance parallels our heart rhythms and blood flow. Although dance seems to rev people up, it actually reduces stress and cortisol levels."

Stoessel loves arugula salad with winter squash for a quick and healthy lunch. "Winter squash contains an impressive amount of immune-supportive vitamin A and vitamin C, as well as dietary fiber, manganese, copper, potassium, folate, manganese, vitamin B6, vitamin K, vitamin B3, and omega-3 fatty acids," says John Staughton, BASc, BFA. "Although every winter squash is slightly different and may have varying levels of carbohydrates, antioxidants, minerals, vitamins, and nutrients, the cultivars listed above tend to share many of the same nutritional components."

Stoessel is a big fan of sushi for dinner with friends. "If you eat fish just once a week, your hippocampus—the big memory and learning center—is 14 percent larger than in people who don't eat fish that frequently. 14 percent. That has implications for reducing Alzheimer's risk," says Dr. Cyrus Raji, a resident radiologist at UCLA. "If you have a stronger hippocampus, your risk of Alzheimer's is going to go down."

Stoessel has made it clear she doesn't follow restrictive diets and never has, instead choosing to focus on overall health. "Three randomized clinical trials (the gold standard in nutrition research) have shown that by improving what you eat, you can improve cardiovascular risk factors, such as high blood pressure, LDL (bad) cholesterol, and triglycerides, and improve your health," says Katherine D. McManus, MS, RD, LDN.

Stoessel is a seasoned world traveler, something experts say can offer many mental health benefits. "Foreign experiences increase both cognitive flexibility and depth and integrativeness of thought, the ability to make deep connections between disparate forms," says Adam Galinsky, a professor at Columbia Business School. "The key, critical process is multicultural engagement, immersion and adaptation. Someone who lives abroad and doesn't engage with the local culture will likely get less of a creative boost than someone who travels abroad and really engages in the local environment."
