# Research Macronutrient Profiles

Diets built around specific macronutrient ratios -- high protein for muscle building, low carb for keto, balanced macros for general health -- require knowing the macronutrient profile of every food you eat. Finding foods that fit your targets means researching dozens of options and comparing their protein, fat, and carb content per serving.

The search_foods and get_nutrition skills let you look up any food and see its complete macronutrient breakdown. Search for high-protein foods, compare their profiles, and build a list of go-to options that hit your targets. Instead of guessing or relying on incomplete lists from blog posts, you work with real nutritional data.

This is valuable for athletes designing performance diets, trainers creating client meal plans, keto dieters finding compliant foods, and anyone trying to hit specific macro targets consistently. Having accurate macronutrient data takes the guesswork out of diet planning and makes it possible to build truly balanced meals.
