Dietary knowledge and awareness in individuals with diabetes is an important aspect of diabetes management. Several studies have evaluated the awareness of diabetes among the diabetic population. However, limited studies have focused on the relation between nutrition awareness and dietary intake in Indian individuals with diabetes. The present study assessed the awareness and perception regarding the importance of nutrition in individuals with diabetes. It aimed at identifying the knowledge gaps by evaluating the relationship between nutritional awareness and dietary self-care behavior in Indian subjects with diabetes. The study design comprised a cross-sectional survey to assess the awareness about nutrition and nutrient intake in the diabetic population across India. A total of 1000 adults with diabetes were administered a diet recall using Nutri-Calculator, an app-based nutrient calculator, and a structured questionnaire. The nutrient calculator recorded food intake in a 24-hr recall and analyzed nutrient intake in comparison with the respective RDAs (Recommended Dietary Allowances). The nutrient intake report was generated at the end, that mentioned the current intake against the RDA for each survey respondent. The questionnaire evaluated the awareness and perception of the subjects regarding the foods and nutrients that are important in diabetes. The survey was conducted using computer-aided telephonic interview (CATI) methodology and each survey was screened for quality checks after completion. After the survey analysis, it was observed that the majority (95%) of the respondents were aware of the importance of protein intake in diabetes. Nearly, 86.5% assumed that they had an adequate intake of proteins; however, the nutrient intake analysis revealed only 14.8% of respondents were meeting their daily protein requirements. Out of the total respondents, it was observed that 92% of the respondents were aware of the importance of fiber intake in diabetes. Nearly, 81.4% assumed that they had adequate intake of fiber; however, the nutrient intake analysis revealed that only 21.2% of the respondents were consuming a diet adequate in fiber. Furthermore, it was found that the majority of the respondents did not meet the RDAs for micronutrients. Additionally, the study also revealed that dietary deficiency of macronutrients, namely fiber, and protein, resulted in greater hunger pangs in these individuals. In conclusion, the study revealed that the respondents were aware of the importance of protein and fiber in their diet; however, the majority of the respondents consumed a diet deficient in these nutrients as well as micronutrients. This dietary deficiency could have led to an increased frequency of hunger pangs in these individuals. Furthermore, most of the respondents were unaware that a low glycemic index diet is beneficial in the management of diabetes. The study highlighted the need for an effective diet and lifestyle counseling for the management of diabetes.
