Yes she is right in advising diabetics but, for the case of Polly saccarides, I am not agree with her,( cassava, sweet potatoes, ) sweet potatoes have several types for diabetics only those with weak starches are better, whole milk is not good for diabetics, the good milk for diabetics if fermented milk, (sour milk) ,for honey white honey from eucalyptus environment kept bee hives. For dry beans the danger is on the skin which is none fermentable carbohydrates. Which cause the gas production in the intestines. So dry beens should be cooked without the skin ( igihembe) .the average water drinking is 35 mls / kg and this liquid include the liquids containing in vegetables and fruits . On other issues I agree with her on some extent.
