That’s what Dr Sarah taught me to consider when looking at options for food and the rest. DR S encouraged me to eat grainfree, starch free & sugarfree. 2 years after a myocardial infarction & eating this way & taking natural supplements (I also shed my cardiologist after 4 months) I shed 52lbs am full of energy & the black dog is no more. Blood tests continue showing improvement so much so I may live forever!
