Next, let's take a look at the Vitamin density. These values are shown in units of percent of recommended daily intake. And since we're showing 200 calories worth, this means anything above 10% is good.
| Nutrient | beets | grapefruit |
| Choline | 7% | 12% |
| Vitamin A | 1% | 46% |
| Vitamin C | 30% | 287% |
