Here’s what else to consider
If you are a food manufacturer, you need to comply with the food labeling requirements of the FDA or other regulatory agencies. One of the most important information you have to provide on your nutrition facts panel is the percent daily value (%DV) of each nutrient in your product. The %DV tells consumers how much of a nutrient your product contributes to their daily diet, based on a 2,000 calorie intake. But how do you calculate the %DV for your food product? Here are the steps you need to follow.

1 Determine the nutrients
The first step is to determine the amount of nutrients in your product per serving. You can do this by using a laboratory analysis, a nutrient database, or a recipe calculation. The nutrients you have to declare on your label are calories, total fat, saturated fat, trans fat, cholesterol, sodium, total carbohydrate, dietary fiber, total sugars, added sugars, protein, vitamin D, calcium, iron, and potassium. You may also declare other nutrients voluntarily, such as vitamins A and C, or folate.

The %DV on a food label is based on a daily intake of 2,000 calories, Guidelines and regulations vary country wise, so comply accordingly .Here's how you can calculate the %DV for a specific nutrient in your food product:Determine the Reference Amounts: Look at the nutrition facts panel on your food product.Identify amount of the specific nutrient / i serving.Convert G to Mg (if necessary): The %DV is usually expressed in milligrams (mg) or micrograms (mcg). If your nutrient is listed in grams on the label, convert it to milligrams by multiplying by 1,000.Calculate the Percent Daily Value: Divide the amount of the nutrient per serving by the Daily Value for that nutrient.Round to the Nearest Percent: t/whole number..

Launched a high-fiber cereal. Calculated %DV for fiber (5g/serving) using RDV (25g). Got 20%! Highlighted it & boom, sales soared!

To calculate the Percent Daily Value (%DV) for your food product, you need to know the nutrient content of the food item. The nutrients commonly included on food labels and used to calculate %DV include:Total Fat: Includes saturated fat and trans fat.Cholesterol:Sodium:Total Carbohydrates: Includes dietary fiber and sugars.Protein:Vitamins and Minerals: Common ones include Vitamin D, Calcium, Iron, and Potassium.For each of these nutrients, you would need to know the amount present in one serving of your food product. The reference values or Reference Daily Intakes (RDIs) for these nutrients are established by regulatory agencies.

2 Find the reference values
The next step is to find the reference values for each nutrient that are used to calculate the %DV. These values are based on scientific evidence and dietary recommendations, and they vary depending on the type of nutrient. For example, the reference value for total fat is 78 grams, while the reference value for sodium is 2,300 milligrams. You can find the reference values for all the nutrients on the FDA website or in the Code of Federal Regulations.

RV, or RDI vary as per country and their regulations..They can be found in title 21 of CFR, FDA guidance documents, for EU refer FFSA, it may require to consult codex and WHO guidance documents.Refer FSSAI website, scientific journals, national and international research data base.FSSAI periodically issues guidelines, notification and updates.You can also refer to NIN , icmr data published and updated from time to time.

As Per FSSAI RDA calculated on the basis of 2000kcal energy, 67g total fat, 22g saturated fat, 2g trans fat, 50 g added sugar and 2000mg of sodium (5g salt) for average adult per day.

3 Do the math
The final step is to do the math to calculate the %DV for each nutrient in your product. The formula is simple: divide the amount of nutrient in your product by the reference value, and multiply by 100. For example, if your product has 10 grams of total fat per serving, the %DV for total fat is 10 / 78 x 100 = 12.82%. You have to round the %DV to the nearest whole number, except for trans fat, sodium, dietary fiber, vitamin D, calcium, iron, and potassium, which can be rounded to the nearest 0.5%. You have to declare the %DV for all the nutrients on your label, except for protein, which is optional unless you make a protein claim.

The % DV is an indicator that provides an idea of the amount of nutrients a food contains in relation to the recommended daily amount for a healthy adult. %DV is expressed as a percentage and varies depending on the nutrient.

As Per FSSAI Certainly, let's recalculate the Percent Daily Value (%DV) for Total Fat assuming the Reference Daily Intake (RDI) is 67 grams.Assuming your food product has 15 grams of Total Fat per serving:{%DV for Total Fat} = 15/67*100 = Approx 22.39\%Rounded to the nearest whole number, the %DV for Total Fat would be approximately 22%.

I agree that RDAs are important to consider. While at the same time certain countries also have minimum %dv requirements to list that particular nutrient in the nft panel. For example in EU there is a cut off of minimum 15% dv for a nutrient for it to be listed in the nft.

4 Check the label format
Once you have calculated the %DV for your product, you have to check the label format to make sure it complies with the FDA requirements. The label format has changed recently to reflect the updated nutrition science and consumer preferences. Some of the changes include larger and bolder fonts for calories and serving size, a separate line for added sugars, and updated serving sizes based on what people actually eat. You can find the new label format and examples on the FDA website or in the Code of Federal Regulations.

Serving Size: 1 serving (example: 100g)Amount Per Serving:- Total Fat: 15g - % Daily Value: 22%This example assumes the serving size is 100 grams. The %DV is calculated based on the assumption of a daily caloric intake of 2,000 calories.

5 Review the label claims
The last thing you have to do before printing your label is to review the label claims you want to make about your product. Label claims are statements that highlight certain aspects of your product, such as low fat, high fiber, or gluten free. Label claims can help you attract consumers and differentiate your product from competitors, but they also have to be truthful and not misleading. The FDA has specific definitions and criteria for different types of label claims, such as nutrient content claims, health claims, and structure/function claims. You have to make sure your product meets the requirements for any claim you make, and you have to provide the appropriate disclaimer or disclosure if needed.

There are separate criteria and conditions listed for such kind of nutrient content claims such as when can we say high, low or source of that nutrient. Only when the conditions are met, we should make that claim on the label.

Use %DV to help distinguish one claim from another, such as "light,” “low,” and “reduced. For example, a %DV is required to be listed if a "high in protein" claim is made. The %DV for protein must also be listed on the label if the product is intended for infants and children under 4 years of age. However, if the product is intended for the general population 4 years of age and older and a claim is not made about protein on the label, the %DV for protein is not required.

The first four steps are procedural and with well defined sources and methods should yield accurate data and precise label format. Caution at this step though. This is where subjectivity can creep in and non-compliances can start to appear. The assessment of claims should be as rigorous as the preceding steps.

6 Follow the best practices
Calculating the %DV for your food product requires attention and accuracy to avoid errors and ensure compliance. You should use reliable sources of data, such as accredited laboratories, reputable databases, or validated software. Additionally, it's important to keep records of your nutrient analysis, reference values, calculations, and label format and update them when you change your product formulation, packaging, or serving size. Moreover, consulting FDA guidance documents, regulations, and resources for food labeling is essential. If you have any questions or doubts, seek professional advice. Lastly, review your label periodically to compare it with the latest nutrition science and consumer trends and make adjustments if necessary.

One should create its own formulae by entering reference values of relevant nutrients, enter analysed nutrient value in the product and get % DV straight - simple.
