The nutrients behind the nutrients
Micronutrients — vitamins and minerals — are needed in milligrams rather than grams, and carry no calories at all. What they carry is function: iron moves oxygen, calcium and vitamin D build bone, B vitamins run energy metabolism, sodium and potassium balance fluids and blood pressure. Deficiencies rarely announce themselves; they just show up as tiredness, poor recovery, or worse bloodwork.
Diets create blind spots
Every eating pattern has predictable gaps. Cut dairy and calcium needs watching; go plant-based and iron and B12 come into question; eat few vegetables and fiber, potassium, and magnesium sag together. Calorie deficits make everything tighter — less food means fewer chances to hit every mark, which is why micronutrition matters more while dieting, not less.
Food first
The reliable strategy isn't memorizing tables — it's variety: colorful vegetables and fruit, some animal or deliberately-chosen plant proteins, dairy or its alternatives, nuts and legumes. A varied diet covers most needs without anyone doing arithmetic; supplements are for specific, identified gaps.
What the app can show you
Where your foods carry label data, the app tracks a broad set of micronutrients — and lets you set a floor, target, or ceiling on the ones you're managing. Treat those trends as directional (they're only as complete as your labels), and treat persistent concerns as a conversation with a professional, not a settings problem.
