In terms of Physical body

VYANA Governs the movement of energy from head down to the Naval which is the Pranic center.

APANA Governs the movement of energy from the Naval down to the mooladhara and all the way down to the feet.

UDANA Governs the movement of energy from the naval up to the head.

The naval is the main Prana center in the body, in which all Pranas are held like the spokes in the center of the wheel.

Special Note: Most of us are only “PART TIME YOGIS” and a judicious combination of all the above diets will give us enough strength – Physically, Mentally and Spiritually.

Non-Vegetarians often ask a question --- “What about Proteins?”

Protein is built from amino acids. There are 22 amino acids used in the body. The body itself is able to produce 13 of them. The other 9 are referred to as “essential amino acids” which the body gets from the food. Most of the essential amino acids are found in abundance in food (Yes, even in Vegetarian diet). So eating a variety of food would help us get most of the amino acids. For the critical amino acids, remember the grains are relatively high is tryptophone and methionine and legumes are relatively high in lysine. So combine one grain and one legume to get a complete protein (Ideal is 2/3 grain 1/3 Legume). Eg;: Rice & Beans, Pasta & Tofu. We also get “Complete” protein by combining a grain or legume with milk.

Eg; Oats meal with milk.
