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.
| Buckwheat | Wheat bran |
| Nutrient | buckwheat | wheat bran |
| Protein | 8g | 14g |
| Carbohydrate | 42g | 60g |
| Fiber | 6g | 40g |
| Fat | 2g | 4g |
| Monounsat. Fat | 1g | 4g |
| Polyunsat. Fat | 1g | 2g |
| Saturated Fat | 0g | 1g |
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 | buckwheat | wheat bran |
| Choline | 0% | 16% |
| Vitamin A | 0% | 0% |
| Vitamin C | 0% | 0% |
| Vitamin E | 0% | 11% |
| Vitamin K | 0% | 2% |

And here we see the B-vitamins: B1 (Thiamin), B2 (Riboflavin), B3 (Niacin), B5 (Pantothenic Acid), B6 (Pyridoxine)
| Nutrient | buckwheat | wheat bran |
| Vitamin B1 | 6% | 48% |

| Vitamin B6 | 11% | 110% |
| 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.
