Abstract

Rapid progress and developments are happening in the field of personal genomics and with increasing personalized nutrition services available on the market, but gene based personalised nutrition is not widely practiced or accepted in India. In recent times, it is quite evident that awareness and popularity about genetic testing for personalised nutrition is gaining momentum. Consumer attitudes and perceptions towards genetic testing to determine the risks of a predisposition to various diseases have already been examined by several studies, consumer acceptance of personalised nutrition have not been studied in the Indian population till date. Therefore, this study is aimed to examine consumer acceptance of personalised nutrigenetic testing in India. About 500 consumers who underwent the nutrigenetic tests were interviewed using a questionnaire. Forty eight percent of the participants were males and 52% were females. The mean age was 38.3 ± 14.9 years. Eighty five percent of participants who were diagnosed with type 2 diabetes reported being willing to follow the dietary recommendations based on their genetic makeup. The responses towards perceived advantages of receiving DNA based dietary advice were ease of understanding and specificity of the diet advice, which was the most frequently reported theme (57.5%), followed by more personalised and enjoyable (22.4%) and reduced costs due to disease prevention (20.1%). It can be concluded that individuals were optimistic and perceived many advantages of nutrigenetic testing. Individuals are able to perceive risks and benefits, but do not seem to fully understand the risks associated with privacy issues and ownership of personal genetic information. Our study supports that the population is optimistic and willing to adopt genetic tests for personalised nutrition recommendations.
