Nutritionist. Bluffton University, MS In today's world, people's eating and exercise patterns have changed, and it is often lifestyle that is the cause of many diet-related illnesses. I believe that each of us is unique – what works for one does not help another. What is more, it can even be harmful. I am interested in food psychology, which studies a person's relationship with their body and food, explains our choices and desires for specific products, the difficulty of maintaining optimal body weight, as well as the influence of various internal and external factors on appetite. I'm also an avid vintage car collector, and currently, I'm working on my 1993 W124 Mercedes.
