# Track Micronutrient Content

Most people track calories and macros but ignore micronutrients -- the vitamins and minerals that are equally important for health. Iron deficiency causes fatigue. Low vitamin D weakens bones. Insufficient B12 affects brain function. Yet finding which foods are rich in specific micronutrients requires digging through scattered databases and conflicting information.

The get_nutrition skill returns the full micronutrient profile of any food, including vitamins A, B, C, D, E, K, iron, calcium, potassium, magnesium, zinc, and more. Search for foods rich in the micronutrients you need, compare options, and build a diet that covers all your nutritional bases -- not just the macro ones.

This is valuable for people with identified deficiencies looking for food-based solutions, vegetarians and vegans ensuring they get nutrients typically found in animal products, pregnant women tracking folate and iron, and health professionals building comprehensive nutrition plans for clients.
