For instance, a study performed by scientists at Pomona School discovered a processed-food meal of white bread and American cheese elevated TEF about 10%, whereas a whole-food meal of multi-grain bread and cheddar cheese elevated TEF about 20%. The distinction would doubtless be even increased if the themes ate a meal of high-fiber greens and lean protein (which is even much less processed than multi-grain bread and cheddar cheese).
