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.
| Tuna | Egg |
| Nutrient | tuna | egg |
| Protein | 44g | 18g |
| Carbohydrate | 0g | 1g |
| Fiber | 0g | 0g |
| Fat | 1g | 14g |
| Monounsat. Fat | 0g | 14g |
| Polyunsat. Fat | 1g | 2g |
| Saturated Fat | 0g | 4g |
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 | tuna | egg |
| Choline | 12% | 83% |
| Vitamin A | 5% | 31% |
| Vitamin C | 0% | 0% |
| Vitamin E | 5% | 11% |
| Vitamin K | 0% | 1% |
Egg have significantly more Vitamins A, E than tuna. Tuna are a great source of Vitamin B6, Phosphorus, Iron. Tuna are an excellent source of Niacin, Vitamin B12. Egg are a good source of Vitamin A. Egg are a great source of Riboflavin, Pantothenic Acid, Vitamin B12, Phosphorus, Iron.
And here we see the B-vitamins: B1 (Thiamin), B2 (Riboflavin), B3 (Niacin), B5 (Pantothenic Acid), B6 (Pyridoxine)
| Nutrient | tuna | egg |
| Vitamin B1 | 6% | 10% |
| Vitamin B2 | 12% | 61% |
| Vitamin B3 | 191% | 1% |
| Vitamin B5 | 7% | 40% |
| Vitamin B6 | 55% | 18% |
| Vitamin B12 | 258% | 90% |
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 | tuna | egg |
| Sodium | 39% | 13% |
| Potasium | 12% | 5% |
| Calcium | 4% | 15% |
| Magnesium | 13% | 5% |
| Phosphorus | 48% | 46% |
| Iron | 44% | 43% |
| Manganese | 1% | 2% |
| Selenium | 308% | 99% |
| Copper | 9% | 14% |
| Zinc | 14% | 17% |
