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.
| Kale | Protein |
| Nutrient | kale | protein |
| Protein | 14g | 48g |
| Carbohydrate | 40g | 4g |
| Fiber | 0g | 3g |
| Fat | 3g | 2g |
| Monounsat. Fat | 0g | 2g |
| Polyunsat. Fat | 1g | 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 | kale | protein |
| Choline | 0% | 27% |
| Vitamin A | 114% | 0% |
| Vitamin C | 503% | 0% |
| Vitamin E | 0% | 0% |
| Vitamin K | 0% | 0% |
Kale have significantly more Vitamins A, C than protein. 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. Protein are a good source of Zinc, Calcium. Protein are a great source of Phosphorus. Protein are an excellent source of Iron.
And here we see the B-vitamins: B1 (Thiamin), B2 (Riboflavin), B3 (Niacin), B5 (Pantothenic Acid), B6 (Pyridoxine)
| Nutrient | kale | protein |
| Vitamin B1 | 29% | 10% |
| Vitamin B2 | 25% | 5% |
| Vitamin B3 | 47% | 7% |
| Vitamin B5 | 7% | 1% |
| Vitamin B6 | 90% | 5% |
| 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.
| Nutrient | kale | protein |
| Sodium | 134% | 40% |
| Potasium | 56% | 1% |
| Calcium | 189% | 21% |
