### Parameters

- **Required fields**: *name*, *kJ*, *carbs*, *fat*, *protein*. You must state the units of measurement that are being used, except for kJ, which is in kilojoules (1 Calorie = 1 kcal = 4.2 kJ). The units are usually expressed in grams (g), for example: .
- **Note**: To specify energy in kcal rather than kJ, use *kcal* instead.
- **Optional fields**: *image*, *caption*, *serving_size*, *sugars*, *lactose*, *satfat*, *transfat*, *monofat*, *polyfat*, *omega3fat*, *omega6fat*, *fiber*, *starch*, *water*, *cholesterol*, *alcohol* and *caffeine*. Again, you must state the units that are being used.
- **Contributor defined fields**: Additional fields can be added using the *opt1n* and *opt1v* fields, where *n* is for name and *v* is for value. Up to four optional fields are supported, *opt1n* & *opt1v* up to *opt4n* & *opt4v*.  
;The following optional variables are converted into percentages of RDA (taken as averages for males and females aged 25–50 years from the USDA 2000 recommendation):
- **Minerals** (in mg) - *calcium_mg*, *copper_mg*, *iron_mg*, *phosphorus_mg*, *magnesium_mg*, *manganese_mg*, *selenium_ug*, *sodium_mg*, *potassium_mg*, *zinc_mg*. Write the number without the unit.
- **Vitamins** (in mg, μg, or international units) - *vitA_ug*, *vitA_iu* (in IU), *vitA_asbeta_iu* (in IU), *betacarotene_ug* (subcategory of vitamin A!), *thiamin_mg* (vit. B<sub>1</sub>), *riboflavin_mg* (vit. B<sub>2</sub>), *niacin_mg* (vit. B<sub>3</sub>), *pantothenic_mg* (pantothenic acid), *vitB6_mg*, *folate_ug*, *vitB12_ug*, *choline_mg*, *vitC_mg*, *vitD_ug*, *vitD_iu* (in IU), *vitE_mg*, *vitE_iu*, *vitK_ug*. Write the number without the unit.  
; Other optional variables and flags:
- **note** - a convenient way to indicate serving sizes or edible parts, e.g., *1 banana is 100 to 150* g or other information.
- **source** - sets the data source of the information used in the template.
- **source_usda** - a *1* in this field will automatically set the source as the USDA database.
- **noRDA** - optional suppression of RDA message: noRDA=1
- **float** - will cause the table to appear on the side of the article, for centered, and to place it on the , but without wrapping text around it. The default is .  
; Additional notes:
- According to convention, there should be a non-breaking space between the number and the unit: "14&amp;nbsp;g" (which displays as "14&nbsp;g") and not "14g".
- Don't specify numbers in too many decimals.
- Splitting up components that are present in trace amounts is not very meaningful (e.g. 1.5 g fats of which 0.5 g unsaturated).
- Only vitamins and minerals for which this product is considered to be a good source should be included, in order to prevent clogging up the article with a huge table.
Nutritional values can be found in the USDA's FoodData Central (formerly National Nutrient Database). Note that fibers are counted as carbohydrates. Note also that the calculated energy value given in the USDA database sometimes includes 4 kcal per gram of fibre, which is not really correct, and it would be better for Wikipedia articles to exclude the fibre from the energy value. (The USDA documentation says, "For
multi-ingredient processed foods, kilocalorie values (source codes 8 or 9; ...) generally reflect industry practices (as
permitted by NLEA) of calculating kilocalories as 4, 4, or 9 kilocalories per gram of
protein, carbohydrate, and fat, respectively, or as 4, 4, or 9 kilocalories per gram of
protein, carbohydrate minus insoluble fiber, and fat. The latter method is often used for
high-fiber foods.")
