One way of quantifying it really roughly is to estimate the total caloric value of worldwide food production and divide by the population, to get a global estimate of calories-per-person. According to one estimate, anyway, that's been steadily rising and is now around 2900 kcal/person/day [1]. There still is hunger in some parts of the world, which suggests that the problem is distribution not happening correctly, whether due to logistical or economic or political issues. This seems to be true even if you do the averaging per-continent: the continent with the lowest per-capita production, Africa, still produces 2600 kcal/person/day, which should be plenty to avoid starvation.
