If our digestion is proper, our body gets the ability to produce healthy tissues (dhatus). If the digestion is weak, the connective tissues of our body: blood, muscle and nerve may not function properly & thus, become susceptible to diseases. The cause of digestive diseases is directly proportional to our actions. By indulging in unhealthy eating habits, the functioning of our bodily doshas becomes unbalanced. Vata becomes upset by dry, cold and light foods such as raw vegetables. Pitta is upset by oily and warm foods such as deep fried vegetables while Kapha is upset by moist, heavy and cold foods such as yogurt and ice cream. Additionally, eating foods improperly is even more harmful than choosing unhealthy foods. Healthy food taken in a wrong way can also lead to digestive ailments.
