According to yogic principles, yoga & food are interrelated. Yoga places great emphasis on food. In fact, in yoga we find a whole branch called Anna Yoga dedicated to food. According to yogic principles we become what we eat. The effects of an improper diet manifest themselves in unwanted appearance, incorrect thoughts, behavior and action.
In yoga & food one finds that the emphasis is not placed on minerals, proteins, or vitamins. Instead food is classified according to three Gunas (qualities).
Another important point to understand about yoga & food is that cooking can change the nature of the food. In other words sattavic food can become rajasic or tamasic food when cooked with spices or stored for a long period of time. For instance, when honey is cooked it becomes rajasic food. Similarly when fruits are stored for a long period of time they become tamasic. Grains, on the other hand, remain sattavic even if stored for a long period of time.
According to yoga & food approach, vegetarian diet is the best diet. Fish and meat products are specifically prohibited in yoga. According to Yoga Sutras written by Patanjali, eating meat violates the principle of non-violence. If it is proteins that we are looking for in meat, then you should know that proteins can also be derived from nuts, legumes and dairy products.
Another interesting fact about yoga is that it also helps to cleanse our body of toxins. There are many postures and breathing techniques in yoga that help to cleanse the body and promote a balanced and healthy body.
Talking about the subject of yoga & cleansing, even food is used in yoga to help cleanse our body. According to yogic principles, fasting helps cleanse our body of toxins and provides rest to cells. Moreover, certain foods are easy on our system and help cleanse our body of toxins.
Yoga & food help the practitioners of yoga achieve a healthy lifestyle.
