Food
🔥 Calories: Calories show energy per 100 g and help you compare portion impact across foods. Use them with protein and carbs to see whether an option fits maintenance, deficit, or surplus goals. A low score does not mean a food is ‘bad’ — it reflects nutrient density for general health, not your specific plan.
💪 Protein: Protein per 100 g shows how concentrated a food is as a protein source. Higher values support muscle recovery, satiety, and meal balance when that is your priority. Compare foods on this page rather than judging a single macro in isolation.
🌾 Carbs: Carbs matter most in context: training days, ketogenic diets, and endurance goals change what ‘good’ looks like. Powders such as maltodextrin score lower on our general-health scale because they are energy-dense with little protein, fiber, or micronutrients — not because they are never useful.
🥑 Fat: Fat carries more than twice the calories per gram than protein or carbs, so small portion changes matter. Moderate fat levels can support hormones and absorption of fat-soluble vitamins. Use this column with calories when balancing satiety and energy density.
The data shown is filtered to match this page’s topic.
The NutriDecide score (1–10) ranks foods on this page by protein, nutrient density, fiber, and a general-health lens — not by taste or whether they fit a specific diet. Low scores (e.g. maltodextrin) usually mean fewer nutrients per calorie; high scores (e.g. soy protein isolate) mean stronger protein and micronutrient density. It is a comparison tool: a low score does not forbid a food when it matches your goal.
