Amaranth grain, uncooked
Historical reference: USDA FoodData Central SR Legacy, April 2018. Values describe the named edible portion and preparation, not every food with a similar name or a current retail formulation. Missing values are not zero.

What the nutrition record actually describes
The reference is USDA FoodData Central food 170682, from the April 2018 SR Legacy release. Its basis is per 100 g edible portion. Food names in search results can hide important differences: the record description, rather than the broad headline alone, determines whether this panel matches your serving.
The figures below are scaled from that source record. Missing nutrients are labeled “Not reported”; an absent sugar value is not evidence that a food contains no sugar. Values may be rounded, and a current product label takes precedence for that exact packaged product.
Dry grain is not cooked grain
Uncooked amaranth contains less water per gram than the prepared grain. Adding water increases batch weight while leaving the original grain energy roughly distributed across the larger cooked yield.
Weigh dry grain when calculating a whole batch, or select a cooked entry when weighing a bowl after cooking. Mixing the two states is a common reason a grain log appears unexpectedly high or low.
Calculated portion examples; not serving recommendations
| Edible portion | Energy | Protein | Carbohydrate | Fat |
|---|---|---|---|---|
| 25 g | 92.8 kcal | 3.4 g | 16.3 g | 1.8 g |
| 50 g | 185.5 kcal | 6.8 g | 32.6 g | 3.5 g |
| 75 g | 278.3 kcal | 10.2 g | 48.9 g | 5.3 g |
| 100 g | 371 kcal | 13.6 g | 65.2 g | 7 g |
| 150 g | 556.5 kcal | 20.4 g | 97.8 g | 10.5 g |
How to calculate the portion on your plate
Multiply the per-100-g value by your edible portion in grams and divide by 100. A 75 g portion of this reference has approximately 278.3 kcal; a 150 g portion has approximately 556.5 kcal. Those are mathematical examples, not recommended serving sizes.
Use the same scaling for protein, carbohydrate and fat. For a mixed recipe, calculate each ingredient first, add the batch, then allocate the share eaten. If a finished batch weighs 600 g and you serve 150 g, you have one quarter of the batch nutrition; the recipe's water content affects its final weight.
Where the reference is useful—and where it stops
Use this panel to compare like-for-like portions and to understand what drives the meal total. It does not decide whether amaranth grain (uncooked) is suitable for a particular medical diet, nor does one nutrient describe the quality of an entire day.
A meal can include additional vegetables, grains, proteins, sauces and drinks. Record the components you ate rather than judging the plate from a single ingredient. If you need a sodium or other nutrient limit for a condition, use the plan agreed with your healthcare professional.
Logging amaranth grain (uncooked) with BiteCal
Photograph the meal in good light with the whole serving visible. Review the foods the scanner suggests, match the preparation, and adjust the portion before saving. Photo recognition is a starting estimate; it cannot read the weight under a pile of food or identify every hidden recipe ingredient.
Compare the saved calorie and macro totals with the reference and your portion calculation. Review the daily diary rather than assuming one scan is exact. A label or measured homemade recipe is often a better source when the product or recipe is known.
Frequently asked questions
How many calories are in 100 g of amaranth grain (uncooked)?
371 kcal in this specific USDA reference. Match the food description and preparation before applying that number to a meal.
Can I use the same number for a different brand?
Use the current product label if you have one. The historical USDA entry describes amaranth grain, uncooked, so a different formulation or preparation may differ.
Why does my food diary show another value?
Check whether the entries use the same grams, preparation state, edible portion and source. A cooked item, dry ingredient and complete recipe can have different values even when their names look similar.
