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.

| Nutrient | chicken | crab |
| Protein | 20g | 44g |
| Carbohydrate | 0g | 0g |

| Fat | 13g | 1g |
| Monounsat. Fat | 5g | 1g |
| Polyunsat. Fat | 3g | 0g |
| Saturated Fat | 4g | 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 | chicken | crab |
| Choline | 12% | 0% |
| Vitamin A | 6% | 3% |
| Vitamin C | 0% | 22% |
| Vitamin E | 2% | 0% |
| Vitamin K | 4% | 0% |

Crab are a good source of Vitamin C, Niacin, Vitamin B6, Magnesium, Calcium, Iron. Crab are a great source of Phosphorus. Crab are an excellent source of Vitamin B12, Zinc.
And here we see the B-vitamins: B1 (Thiamin), B2 (Riboflavin), B3 (Niacin), B5 (Pantothenic Acid), B6 (Pyridoxine)
| Nutrient | chicken | crab |
| Vitamin B1 | 5% | 10% |

| Vitamin B5 | 18% | 17% |
| Vitamin B6 | 23% | 32% |
| Vitamin B12 | 12% | 1071% |
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 | chicken | crab |
| Sodium | 5% | 133% |
| Potasium | 5% | 14% |
