Mediterranean Diet

Traditional Mediterranean Diet has long been considered as a healthy diet that includes all necessary nutrients for living a healthy life. Dr. Ancel Keys was the first scientist to point out the health values of a Mediterranean styled diet.

This was the diet of the people of Greece and Southern Italy. Nowadays, these countries no longer follow the traditional Mediterranean Diet in its original form. Like rest of the world, processed foods and junk food have found its way into their diet.

Busy schedules and modern lifestyle leaves little room and time to enjoy meals with family and friends on a regular basis. Often food is consumed in the presence of distractions like TV, Internet, gadgets etc. This practice often leads to eating fast and not being able to control the portion sizes.
