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.

| Carbohydrate | 1g | 0g |

| Monounsat. Fat | 1g | 7g |
| Polyunsat. Fat | 0g | 0g |
| Saturated Fat | 0g | 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 | lobster | beef |
| Choline | 42% | 24% |
| Vitamin A | 7% | 0% |
| Vitamin C | 0% | 0% |
| Vitamin E | 27% | 3% |

And here we see the B-vitamins: B1 (Thiamin), B2 (Riboflavin), B3 (Niacin), B5 (Pantothenic Acid), B6 (Pyridoxine)
| Nutrient | lobster | beef |
| Vitamin B1 | 1% | 6% |

| Vitamin B12 | 103% | 164% |
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 | lobster | beef |
| Sodium | 44% | 6% |
