First, let's take a look at the macros. Each of these are listed in grams and as usual, normalized to 200 calories for easy comparison, so we're always comparing apples to apples.

| Monounsat. Fat | 0g | 3g |
| Polyunsat. Fat | 0g | 1g |
| Saturated Fat | 0g | 0g |
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 | potato | kale |
| Choline | 7% | 0% |
| Vitamin A | 0% | 114% |
| Vitamin C | 68% | 503% |
| Vitamin E | 0% | 0% |

Potato are a great source of Vitamin C, Vitamin B6. Kale are a good source of Thiamin, Riboflavin. Kale are a great source of Niacin, Vitamin B6, Potassium, Phosphorus. Kale are an excellent source of Vitamin A, Vitamin C, Magnesium, Calcium, Iron.
And here we see the B-vitamins: B1 (Thiamin), B2 (Riboflavin), B3 (Niacin), B5 (Pantothenic Acid), B6 (Pyridoxine)

| Vitamin B6 | 70% | 90% |
| Vitamin B12 | 0% | 0% |
Now, lets look at mineral density. Here we have a lot of important electrolytes and minerals. Once again, units are in percent of RDI, thus for this 200 calorie serving anything above 10% would considered high.
