White Onion
On Average
First, we aggregate all of the data we have for this food type, and then use the averages for each measurement.
Calories is calculated by averaging the kcal of each dataset for this food type.
For Edacious Datasets we sum the kcal from protein, fat, and carbs using Atwater general factors (4 kcal/g of protein, 9 kcal/g of fat, and 4 kcal/g of carbs).
For USDA Datasets we use USDA's own energy value. When a dataset does not have that, we use its Atwater specific value, then its general value.
Top Beneficial Nutrients
Top beneficial nutrients are those a food provides in the highest amounts relative to your daily needs (daily value). Daily Values (DVs) are set conservatively to cover nearly the entire population—helping you quickly spot what a food is exceptionally rich in.
The average is the arithmetic mean of the observed sample values.
The Average %DV is the average of the observed sample values converted to a percentage of the daily value for this nutrient.
The percent daily value (DV) range represents the 5th to 95th percentile of sample values expressed as daily value percentages.*
*The bottom 5% and top 5% of values are excluded to prevent outliers from skewing the data.
Represents how much the nutritional value of a particular nutrient can vary expressed as a percentage of the daily value (DV). This is calculated by taking the difference of the low end and the high end %DV range*.
*The bottom 5% and top 5% of values are excluded to prevent outliers from skewing the data.
The DV range is a representation of our dataset and not necessarily the market. In certain cases, the variability (DV range) may be caused by small sample sizes.
