DRI Calculator

The DRI calculator is the ultimate way to compute all the necessary macro-, micronutrition, and vitamins needed in your daily menu.

🥦 Looking for ways to improve your diet? Our daily nutritional requirements tool will supply you with an overview of your caloric needs, adequate to your level of activity and eventual status of pregnancy or lactation.

Dietary reference intake or daily recommended intake? Keep on reading to discover what are your target vitamin levels and how many grams of proteins per day is enough.

Don't forget to visit the vitamin calculator and the protein calculator for a dose of specific knowledge on these subjects!

DRI stands for the dietary reference intake, sometimes incorrectly called the daily recommended intake. National Academy introduced the DRIs in 1997 - they serve as a source of multiple daily nutritional requirements in both the US and Canada. To put it simply, the DRIs tell us how much water, calories, macronutrients, and vitamins a given person should consume daily - the entire estimation is based on sex, age, and activity level. 🚴

The professionals may use the DRI recommendations to create diets for people in different public institutions, such as hospitals, schools, or prisons. They're also helpful for companies coming up with new foods or dietary supplements.

We can distinguish a few different types of recommendations:

• Estimated Average Requirements (EAR) - can statistically satisfy the needs of 50% of people in a given group;
• Recommended Dietary Allowances (RDA) - satisfy the needs of 97.5% of people in a given group; (we base our DRI-RDA calculator mostly on these)
• Adequate Intake (AI) - for less precise estimation;
• Acceptable Macronutrient Distribution Ranges (AMDR) - ranges written in percentages, helpful in calculating protein needs and estimating the amount of fats or carbohydrates a given person should consume.

In order to calculate your daily nutrition, we need to know a few things:

1. Your daily caloric needs.
   The amount of calories you should consume daily, multiplied by your activity level allows us to:
   • Calculate your protein intake
     10-30% of total calories (for adults)
   • Amount of fats -
     20-35% of total calories (for adults)
   • Consumption of carbohydrates
     45-65% of total calories
   • Recommended water intake
     1 kcal = 1 mL
   • Number of grams of fiber
     Fiber = (kcal/1000) × 14

2. Your DRI category.

Our RDA calculator divides the population into multiple groups based on sex, age, and the presence or absence of pregnancy or lactation. We took these populations from the Recommended Dietary References tables published by the National Institutes of Health (NIH).

The given category allows us to discover:

• Your target vitamin amount given in mg, mcg or IU ;
• Your recommended macronutrients intake in grams and calories (see: grams to calories calculator); and
• The amount of minerals you should consume daily.

With all this knowledge combined, our DRI calculator for healthcare professionals can be easily used by everyone who's willing to improve their nutrition score.

To calculate your protein needs, follow these few simple steps:

1. Compute your total caloric needs.

   Use one of the BMR equations, e.g., Mifflin - St Jeor formula.

2. Find your age group and the recommended percentage in the table below:

Choose lower/ upper range or both.

3. Calculate the amount of calories.

   Proteins (calories) = (Total calories × Recommended percentage) / 100

4. Calculate the amount of grams.

   Proteins (grams) = Proteins (calories) / 4

5. That's it! You're all done. 🎉

It's not that difficult - we have four extra steps in front of us:

1. Compute your total caloric needs.

   Use one of the BMR equations, e.g., Mifflin - St Jeor formula.

2. Find your age group and the recommended percentage in the table below:

Choose lower/ upper range or both.

3. Calculate the number of calories.

   Fat (calories) = (Total calories × Recommended percentage) / 100

4. Calculate the amount of grams.

   Fat (grams) = Fat (calories) / 9

5. Wow! You've done it! 🎉

Let's do it together:

1. Compute their total caloric needs.

   Use one of the BMR equations, e.g., Mifflin - St Jeor formula.

2. Calculate the number of calories.

   Recommended amount of carbohydrates in our diet equals 45-65%. You may want to find out the lower, higher threshold, or both.

   Carbs (calories) = (Total calories × Recommended percentage) / 100

3. Calculate the amount of grams.

   Carbs (grams) = Carbs (calories) / 4

4. That was simple, wasn't it? 🎉

To find the daily recommended intake of iron, we need to use one of the Recommended Dietary Allowances (RDA) tables of the National Institutes of Health (NIH).

🤰 These amounts are a bit different for pregnant or lactating women:
