These nutrients do not slow the  absorption of sugars from the intestinal tract. They lower the sugar  levels merely by ensuring that the sugars are properly metabolized in  the body.
 - A regular intake of leeks has been associated with the raise in  the HDL (High Density Lipoprotein or ‘good’ cholesterol) levels and the  corresponding decrease in the LDL or Low Cholesterol Lipoprotein levels.  Maintenance of this balance in the body is very essential as it helps  in the prevention of either the onset or the progression of plaques in  the blood vessels in the body. It is this plaque formation that leads to  the occurrence of atherosclerosis and diabetic heart disease in humans.  Progression of these plaques can even result in a heart attack or  stroke.
