For those who want an accuate definition of Carbohydrate. From my older biochemistry textbook,
'Carbohydrates are compounds of carbon, hydrogen and oxygen, where usually, but not always, the proportion of Hydrogen to Oxygen is 2 Hydrogen atoms to 1 Oxygen atom. The carbohydrates are sometimes referred to as saccharides, from the Greek for sugar.'
I think a lot of people are confused by the way that the term"carb" is used loosely to mean either a Carbohydrate molecule, or a food containing such molecules.
Since Iwas trained by a strict biochemist, I only use the word "carb" to refer to the carbohydrate molecules, which may be sugars or starches, or the indigestible carb "cellulose" otherwise known as Fibre.
Cereals contain starches, which no-one has ever shown to be essential nutrients. Neither have they with sugars. there may be some useful nutrition in foods which are largely "empty carbs". For example there are vitamins present in cereals and in fruits.
So if Iwrite that we don't need carbs, Ihaven't forgotten that apples contain vitaminC. It's just that an apple is a fruit, not a carb. just as porridge is a cereal and potatoes are tubers.
A lot of confusion arrises from imprecise use of language.
I'm not sorry to be a pedant. 8) At least what I write is clear.
