To stay in tip top shape, be selective about what you eat.

“I don’t take any supplements. If we have a well-balanced healthy diet, it will give us all the necessary nutrients we need.”


Dr Andrea Rajnakova’s professional fate was sealed when she received a toy doctor’s set at the age of four. A simple Christmas present launched the child on a journey that eventually led the adult to specialise in gastroenterology.

Passionate about her area of expertise, she says: “Gastroenterology and endoscopy are dynamic, fast-changing medical fields with a wide range of new technologies, innovations and medications developed and implemented in clinical practice over the past 10 years.

“The privilege of using modern technological advances in our daily clinical practice is helping us to provide the best care for our patients.”


As a specialist in the digestive system and its disorders, Dr Rajnakova has a prescription for a healthy lifestyle.

“It is a combination of physical and mental health,” says the gastroenterologist. “How we look is a reflection of our lifestyle and diet. For me, avoiding processed food and engaging in physical activity are two of the most important things to keep fit. I don’t take any supplements and I believe that if we have a well-balanced healthy diet, it will give us all the necessary nutrients we need.”

Processed foods are those that contain artificial colouring, flavouring and additives. A healthy diet, Dr Rajnakova proposes, must contain all necessary nutrients including small amounts of complex carbohydrates, healthy fat, proteins, minerals, vitamins, fibre and water.


Dr Rajnakova emphasises that other factors, such as food portion, mode of preparation, and consumption of meals throughout the day are equally important. As someone who practises what she preaches, the doctor starts her day with freshly prepared vegetable juice, oat husks with chia seeds, and flaxseeds with a banana for breakfast.

“There is a big misconception about superfoods,” she says. “For example, if we take kale but the rest of our food intake consists of processed, deep-fried and fast food, the benefit of the superfood will be lost.”


For a doctor who is dedicated to serving patients on top of her family, there is very little time for anything else. But to tend to both well, she says, it is important to remain in top physical condition.

“I don’t have time to go to the gym,” says Dr Rajnakova. “But I keep myself active by avoiding lifts. I take the stairs no matter which floor I need to go to. I call it self-discipline. The biggest relaxation for me is the time I spend with my family. They bring sunshine into my life.”
