Diabetic thaali

Yava is one of the best Diet advised in ayurveda for Diabetes. This yava is according to me is not Barley, instead i feel it as Oats. This was stuck to my mind when i was in my BAMS. The drugs and diet should be of nutritive and should act as mootr badha (controlling the flow of urination) but Baley is a diuretic, its a popular home rememdy used for reducing oedema of the pregnent women. So it cant be Barley.
The present studies all over the world prove that Oats are the best food supplement due to various reasons and one among such is its high fibrer content and the peculiarity being a slouble fibre. It acts as bulk laxative (yava is one among the foods indicated to increase the quantity of Sakrut in ayurveda)due to its high content of fibre. The present studies show its action against reducing lipids (hyper cholestremia) which is also in accordance to the properties explained in ayurveda. It effectively reduces the blood sugar levels.
Thus with the above research which favors my idea i conclude that Yava is Oats. Even in the preset practice at Delhi, the results are highly encouraging. Whats ur opinion on this?
