Osorno loves being at the beach, which offers health benefits even if you don't swim. "There is mounting evidence, from dozens and dozens of researchers, that nature has benefits for both physical and psychological human well­being," says Lisa Nisbet, PhD. "You can boost your mood just by walking in nature, even in urban nature."

Osorno enjoys shellfish, especially clams and scallops. "Shellfish are rich in several nutrients that are needed in the body," says Faye Dong, PhD. "Iron is an essential mineral in the heme molecule of hemoglobin, the component of the red blood cell that carries oxygen in the bloodstream. People who do not eat enough iron can suffer from iron-deficiency anemia."

Osorno loves tofu-based dishes. Tofu is a great source of protein, making it a good option for vegans and vegetarians. "It's a very nutritious food," said Dr. Qi Sun, an associate professor of nutrition and epidemiology at Harvard T.H. Chan School of Public Health.

Osorno is a huge fan of Japanese cuisine, especially sashimi. "Eating fish fights heart disease in several ways," according to the Harvard T.H. Chan School of Public Health. "The omega-3 fats in fish protect the heart against the development of erratic and potentially deadly cardiac rhythm disturbances."

Osorno enjoys both hot and iced green tea. "Green tea is exceptionally high in flavonoids that can help boost your heart health by lowering bad cholesterol and reducing blood clotting," says Penn Medicine. "Studies show this type of tea can also help lower blood pressure, triglycerides and total cholesterol."
