Żudziewicz enjoys fresh salads, especially with feta cheese. "Feta cheese contains beneficial microbes including yeasts and bacteria, such as Lactobacillus plantarum, which may help support gut health," says registered nutritionist Nicola Shubrook. "In fact, probiotic yeasts from feta have been seen to tolerate low pH levels which puts them at greater chance of surviving the harsh environment of the stomach and getting to the part of the gut where they can be of most value."

Żudziewicz enjoys the energy boost coffee provides. "Coffee may help some people maintain alertness and energy levels thanks to its caffeine content," Shubrook says. "When coffee is consumed, it is absorbed into the bloodstream and travels to the brain where it 'fires up' certain neurons which may improve memory, mood, energy and cognitive function, if consumed in moderation. Other reports suggest drinking coffee before exercise may reduce rates of exertion and potentially improve athletic performance."

Żudziewicz loves delicious calamari for a healthy lunch. "A basket of calamari is, no doubt, one of the most delicious ways to start a meal," says nutritionist Robin Miller. "Nutritionally speaking, calamari (Italian for squid) is crammed with copper (one 3.5-ounce serving has 90% of your RDA). Why should you care? Copper is essential for all this: proper growth of the skeletal, nervous and cardiovascular systems; reducing inflammation and arthritis symptoms; pigmentation of hair, skin and eyes; building connective tissue; stimulating the brain; absorbing iron; stalling aging; producing energy in the body; inhibiting bacteria such as E-Coli; reducing cholesterol and boosting immunity."

Żudziewicz dances for a living, which is a fantastic workout in itself. "Dancing is mainly linked to physical health benefits, but when you dance you are moving different parts of your body in a coordinated way, and this activates several parts of the brain," says the British Heart Foundation. "One small study even found that dancing is associated with a lower risk of dementia. The research, published in the New England Journal of Medicine, followed 469 people aged 75 and over, who didn't have dementia at the start of the study. The researchers measured the association between leisure and physical activities and the likelihood of developing dementia over time. They found that dancing was the only physical activity associated with a lower risk of dementia."

Żudziewicz enjoys swimming. "Swimming is the fourth most popular sports activity in the United States and a good way to get regular aerobic physical activity," says the CDC. "Just two and a half hours per week of aerobic physical activity, such as swimming, bicycling, or running, can decrease the risk of chronic illnesses. This can also lead to improved health for people with diabetes and heart disease. Swimmers have about half the risk of death compared with inactive people. People report enjoying water-based exercise more than exercising on land. They can also exercise longer in water than on land without increased effort or joint or muscle pain."
