Frequently Asked Questions
What does DRI stand for?
DRI stands for Dietary Reference Intake, a set of nutrient recommendations from the Institute of Medicine covering calories, macronutrients, and other nutrients tailored to your personal profile.
Why are protein, fat, and carbs shown as ranges instead of single numbers?
Official DRI guidelines give acceptable macronutrient distribution ranges rather than one fixed target, since healthy diets can reasonably vary in macronutrient balance while still meeting overall calorie and nutrition needs.
Does this calculator cover vitamins and minerals too?
No, this calculator covers calories, macronutrients, and fiber only. Vitamin and mineral reference intakes vary by dozens of individual nutrients and age brackets, and are better looked up individually for the specific nutrient you are interested in.
How is fiber intake calculated?
Fiber is estimated at 14 grams per 1000 calories consumed, a commonly-used general nutrition guideline that scales fiber needs with overall calorie intake.
