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.
| Catfish | Caviar |
| Nutrient | catfish | caviar |
| Protein | 16g | 20g |
| Carbohydrate | 7g | 3g |
| Fiber | 1g | 0g |

| Monounsat. Fat | 5g | 14g |
| Polyunsat. Fat | 3g | 6g |
| Saturated Fat | 3g | 3g |
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 | catfish | caviar |
| Choline | 0% | 92% |
| Vitamin A | 1% | 34% |
| Vitamin C | 0% | 0% |
| Vitamin E | 0% | 13% |

Caviar are a great source of Riboflavin, Pantothenic Acid, Magnesium, Calcium, Phosphorus. Caviar are an excellent source of Vitamin B12, Iron.
And here we see the B-vitamins: B1 (Thiamin), B2 (Riboflavin), B3 (Niacin), B5 (Pantothenic Acid), B6 (Pyridoxine)
| Nutrient | catfish | caviar |

| Vitamin B6 | 15% | 23% |
| Vitamin B12 | 83% | 794% |
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 | catfish | caviar |
| Sodium | 16% | 79% |
| Potasium | 8% | 4% |
