<p style="text-align:justify;">Wholesome called “Pathya” in Ayurveda is the regimen that does not adversely affect the body channels i.e., Patha/Srotasa. The word “Nitya” means constantly/continuously. Criteria for the classification of food items have not been clearly mentioned in the texts of Ayurveda but in context of vitiation of body channels (srotodushti), Acharya Charaka has stated that food and regimens that promote the morbidity by aggravation of doshas and go contrary to the well-being of dhatu vitiates the channels. With the help of this quotation, it can be said that the food that leads to vitiation of body channels by vitiation of dosha and dhatu can be considered as daily non-consumable (nitya asevaniya). On the contrary, it can be said that a diet that does not lead to any srotodushti by vitiation of any dosha and dhatu can be said as daily consumable (nitya sevaniya), maintaining equilibrium of all the dosha. <br/>Daily consumable and daily non-consumable food items have been quoted in ‘Matrashitiya Adhyaya’ of Charaksamhita and Ashtangahrudaya, ‘Annapanavidhi adhyaya’ of Ashtanga Samgraha and Viharavarga of Kaiyyadevanighantu. In a similar context, Ekanta hitakara (solely wholesome) and Ekanta ahitakara (solely unwholesome) food etc. have also been described at various places in the texts of Ayurveda. Nitya sevaniya and Ekanta hitakara dravya have been stated for daily intake for maintenance of health because of their specific properties described in the texts of Ayurveda, while Nitya asevaniya and Ekanta ahitakara dravya are prohibited for regular/long time use because of their harmful effects on body. </p>
