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.
| Chestnuts | Watercress |
| Nutrient | chestnuts | watercress |
| Protein | 4g | 42g |
| Carbohydrate | 44g | 23g |
| Fiber | 0g | 9g |
| Fat | 1g | 2g |
| Monounsat. Fat | 1g | 2g |
| 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 | chestnuts | watercress |
| Choline | 0% | 39% |
| Vitamin A | 1% | 465% |
| Vitamin C | 43% | 1042% |
| Vitamin E | 0% | 152% |
| Vitamin K | 0% | 5682% |

And here we see the B-vitamins: B1 (Thiamin), B2 (Riboflavin), B3 (Niacin), B5 (Pantothenic Acid), B6 (Pyridoxine)
| Nutrient | chestnuts | watercress |
| Vitamin B1 | 14% | 164% |

| Vitamin B5 | 10% | 113% |
| Vitamin B6 | 33% | 213% |
| 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 | chestnuts | watercress |
| Sodium | 0% | 50% |
| Potasium | 11% | 171% |
