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 | red peppers | grapes |
| Choline | 9% | 4% |
| Vitamin A | 162% | 2% |
| Vitamin C | 1098% | 16% |
