Glycemic Index
How fast food turns into glucose in your blood. Affected by the amount of fiber.
Carbohydrates
Carbohydrates in the context of saccharide (biochemistry) includes: sugars, starch, and cellulose.

The recommended daily intake is, according to http://healthyeating.sfgate.com/recommended-amount-percent-carbohydrates-per-day-7287.html:
Carbs_daily = ((Daily_Calories * x) / 4), where 0.45 < x < 0.65.
eg. 2000 * 0.5 / 4 = 250 g/day.
Question: But... Some say carbs are bad (see keto diet). Why?
