Estados Unidos Deja de Utilizar la Pirámide de la Alimentación ... Críticas del Prof. Walter Willet de Harvard..

Las  agencias  federales  de los  Estados  Unidos  dejan  de Utilizar la  Pirámide de la  alimentacion  

 y  ahora  promueven  el  nuevo icono

The Nutrition Source

Out with the Pyramid, In with the Plate 

 

  Nuevas  críticas  del Dr. Walter Willett, Fredrick John Stare Professor of Epidemiology and Nutrition, and chair of the Dept. of Nutrition at Harvard School of Public Health.

En  resumen, en  vez  de  basarse en las más  sólidas evidencias  , los  científicos  norteamericanos , siguen utilizando   estrategias  no completamente transparentes…

“But some of the shortfalls of the Dietary Guidelines themselves—among them, the overemphasis on dairy and the lack of clear messaging on limiting red meat—are repeated on the ChooseMyPlate.gov website.”

 Sigue  el  Prof.Willet:  

In contrast, the Healthy Eating Pyramid from the Dept. of Nutrition at Harvard School of Public Health puts whole grains, vegetables and fruits, and healthy fats in the base. Red meat, butter, soda, sweets, refined grains, and salt are in the used-sparingly tip. Dairy or supplements of vitamin D and calcium are recommended just one to two times a day, not at every meal.

“Clearly MyPlate will be better than MyPyramid, but the most important issues are in the details that are not captured by the icon,” Willett said. “What type of grain? What sources of proteins? What fats are used to prepare the vegetables and the grains?”
