Has there been any more debated food group over the last decade than carbohydrates? Nope!
Do they make us fat? Are they killing our kids? How many carbs do we need in our diet? If you're sedentary do you need them? If you exercise, surely you need them? Can we survive without carbohydrates? Do you need carbs post-workout?
Why are they the topic of such hostile debate?
A carbohydrate is an organic compound that includes simple sugars, disaccharides, and starches. A carbohydrate’s role is supplying energy. Most tissues in the body can use glucose for fuel and most will use glucose unless it's not available. If not derived from food, the body enlists gluconeogenesis to provide glucose from the liver responding appropriately, as needed, to glucagon (a peptide made and secreted from alpha cells in the pancreas). When glucose is not available, fat and ketones are used for energy.
