Micronutrient Tracking Guide
Updated July 19, 2026
Micronutrients — vitamins and minerals — are where most diets quietly fail. The 2020–2025 Dietary Guidelines for Americans identify calcium, potassium, dietary fiber, and vitamin D as nutrients of public health concern because most Americans under-consume them, even in diets that look fine on calories and macros. Tracking them for a single ordinary week shows you which gaps are actually yours.
Why do micronutrient gaps matter?
Chronic shortfalls have specific, well-documented costs: too little calcium and vitamin D drives bone loss, low potassium (paired with high sodium) raises blood pressure, low fiber worsens cholesterol and gut health, and low iron is the most common nutrient deficiency in the world (WHO). None of these show up on a bathroom scale, which is exactly why calorie-only tracking misses them.
How do I find my own gaps?
•
Log a normal week, not a perfect one. Seven days of honest logging beats one curated day — most gaps are weekly-average problems, not daily ones.
•
Look for patterns, not single days. A day low on potassium is noise; a week at 60% of your goal is a real gap.
•
Fix gaps with foods first. Potassium lives in potatoes, beans, yogurt, and fruit; calcium in dairy and fortified alternatives; fiber in legumes and whole grains. Vitamin D is the exception that usually needs fatty fish, fortified foods, or a supplement.
What Kaloris tracks beyond macros
Kaloris tracks 15 nutrients beyond calories and macros: fiber, sugar, saturated fat, cholesterol, omega-3, sodium, potassium, calcium, iron, magnesium, zinc, and vitamins A, C, D, and B12. Each has its own daily goal and history screen, so a gap shows up as an obviously unfilled bar rather than a number you'd have to remember to check. Nutrition data comes from USDA FNDDS for staple foods and Open Food Facts for barcode-scanned packaged foods.
Frequently asked questions
Which nutrients do most people fall short on?
The 2020–2025 Dietary Guidelines for Americans name calcium, potassium, dietary fiber, and vitamin D as nutrients of public health concern because most Americans under-consume them. Iron is an additional concern for women of childbearing age, and vitamin B12 for people eating mostly plant-based.
Which micronutrients does Kaloris track?
Kaloris tracks fiber, sugar, saturated fat, cholesterol, omega-3, sodium, potassium, calcium, iron, magnesium, zinc, and vitamins A, C, D, and B12 — alongside calories and the three macros — with a per-nutrient daily goal and history for each.
Can I get all my micronutrients from food alone?
Mostly yes, with two common exceptions: vitamin D, which is hard to reach from food without fatty fish or fortified products, and vitamin B12 for vegans, which must come from fortified foods or supplements. Tracking a normal week of eating shows you exactly which gaps are yours rather than guessing from generic advice.
Where does Kaloris get its nutrition data?
Staple foods come from USDA FNDDS (the What We Eat in America food database), and packaged foods are looked up by barcode in Open Food Facts, the largest open food database. You can also enter custom foods and recipes with your own label data.
