>who devised and pushed the pyramid stand up and take some >responsibility??

the truth about fats v carbs has gone through the hoop a few times this
century. banting [discoverer of insulin] knew a high fat diet controlled
diabetes.
then we can go right back to ayurvedic medicine which proscribed starches
when the patient was passing sugar in the urine and wasting away.
truth is the same, and liars always attack it. on and on through the ages.
