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.
| Spinach | Grapes |
| Nutrient | spinach | grapes |
| Protein | 25g | 2g |
| Carbohydrate | 32g | 51g |
| Fiber | 19g | 3g |
| Fat | 3g | 1g |
| Monounsat. Fat | 0g | 1g |
| Polyunsat. Fat | 1g | 0g |
| Saturated Fat | 1g | 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 | spinach | grapes |
| Choline | 37% | 4% |
| Vitamin A | 653% | 2% |
| Vitamin C | 326% | 16% |
| Vitamin E | 147% | 5% |
| Vitamin K | 5249% | 54% |
Spinach have significantly more Vitamins A, E, C, K than grapes. Spinach are a great source of Thiamin, Niacin, Zinc, Phosphorus. Spinach are an excellent source of Vitamin A, Vitamin E, Vitamin K, Vitamin C, Riboflavin, Vitamin B6, Potassium, Magnesium, Calcium, Iron. Grapes are a good source of Thiamin, Vitamin B6. Grapes are a great source of Vitamin K.
And here we see the B-vitamins: B1 (Thiamin), B2 (Riboflavin), B3 (Niacin), B5 (Pantothenic Acid), B6 (Pyridoxine)
| Nutrient | spinach | grapes |
| Vitamin B1 | 68% | 28% |
| Vitamin B2 | 149% | 16% |
| Vitamin B3 | 53% | 8% |
| Vitamin B5 | 11% | 1% |
| Vitamin B6 | 154% | 30% |
| 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 | spinach | grapes |
| Sodium | 46% | 0% |
| Potasium | 139% | 16% |
| Calcium | 172% | 8% |
