 [ Symptoms ] good eats for guys claims baked potato as a source of vitamin c   but vitamin c disintegrates at 80 degrees celcius [ Disease ] and the body is 98 6 it is a wonder we all do not all have scurvy assuming you are not an eater of raw potatoes l love raw potatoes as a kid you are correct that heat can destroy some not all of vitamin c i get mine from citrus i do not really count on the versatile potato as my sole source so take your issue up with good eats for guys and see how they defend their statement we can not believe everything we hear and read so i admire you for taking up this stance
