Sustainable nutrition have become widespread throughout the world. It was aimed to question the awareness, knowledge and the attitude of sustainable nutrition in individuals in wide age range. This cross-sectional study was conducted with 3,498 volunteers (1,575 male and 1,923 female) between the ages of 18-95. The questionnaire form was by face to face interview method. The concept of sustainable nutrition was heard higher in women (22.7%), those living in urban areas (22.8%) and in the 18-24 age group (26.6%) (p<0.05). Almost half (49.1%) of the individuals aged 65+ had no idea about the best practice about sustainable nutrition and as the age of the group increased, the knowledge decreased (p<0.05). Only %6 of the individuals heard about the food mile, while the most heard concept was the carbon footprint (28%). There are differences in the attitudes of individuals regarding sustainable nutrition according to gender, age and region of residence.
