Food Tracking

Track your nutrition with 110+ nutrients per food item using camera scanning, barcode lookup, and manual search.

NutriJourney food tracking goes far beyond macros. Every food item is profiled with over 110 nutrients -- amino acids, carotenoids, fatty acid subtypes, phytosterols, vitamins, minerals, and calculated food scores.

Overview

Traditional trackers stop at calories, protein, carbs, and fat. NutriJourney tracks the full nutritional picture:

• Macronutrients -- Calories, protein, carbohydrates, fat, fiber, sugar, saturated fat
• Amino acids -- All 20 amino acids including BCAAs (leucine, isoleucine, valine)
• Vitamins -- A, B-complex (all 8), C, D, E, K
• Minerals -- Calcium, iron, magnesium, zinc, selenium, potassium, sodium, and more
• Fatty acid subtypes -- Omega-3 (ALA, EPA, DHA), omega-6, monounsaturated, polyunsaturated
• Carotenoids -- Beta-carotene, lycopene, lutein, zeaxanthin
• Phytosterols -- Beta-sitosterol, campesterol, stigmasterol
• Food scores -- Glycemic index, glycemic load, PRAL, fullness factor, nutrient density, omega ratio

You do not need to think about all of these at once. NutriJourney uses progressive disclosure -- you start with macros and the detail layers unlock as you progress.

Camera Scanning

The fastest way to log food:

1. Open the My Foods tab and tap the camera icon
2. Point your phone at a meal or individual food item
3. Tap the shutter button -- AI analyzes the image and identifies the food
4. Review and confirm the detection, adjust portions if needed
5. Tap Add to log it

Camera scanning works with plated meals, individual ingredients, and restaurant dishes. For best results, ensure good lighting and keep the food centered in the frame.

Barcode Scanning

For packaged foods with a barcode:

1. Tap the barcode icon in the camera view
2. Align the barcode within the scanning frame
3. NutriJourney looks up the product in the Open Food Facts database
4. Review the nutrition data and tap Add

The barcode database covers millions of packaged food products worldwide.

Manual Search

Search across two major food databases simultaneously:

• USDA FoodData Central -- The United States Department of Agriculture's comprehensive nutrient database
• Open Food Facts -- A community-maintained database of packaged food products worldwide

Combined, these databases cover over 2 million food items. Type a food name, select from the results, and adjust the serving size.

Batch Scanning

When meal prepping or logging multiple items at once:

1. Tap the batch scan icon in the camera view
2. Scan or search for each item -- they are added to a review queue
3. Review all items in the gallery view
4. Tap Add All to log everything at once

This is especially useful for logging an entire meal prep session or a full day of eating in one sitting.

Pantry Management

Track what is in your kitchen:

• Items you scan or search can be saved to your pantry
• See what ingredients you have on hand when planning meals
• Know when staple items are running low

Nutrient Detail Levels

NutriJourney uses progressive disclosure to keep the interface approachable:

• Beginner -- Calories and macros (protein, carbs, fat)
• Intermediate -- Macros plus fiber, sugar, sodium, key vitamins and minerals
• Advanced -- Full 110+ nutrient profile with amino acids, fatty acid subtypes, and food scores

Your detail level advances automatically as you engage with the platform. You can also manually adjust it in settings.

The Multiplier Pattern

Every food item in NutriJourney stores its nutritional data on a per-ounce basis. When you change the serving size, the app multiplies the base values by the quantity:

Per-ounce base data x quantity = total nutrients

This means you get precise nutrition calculations at any serving size -- whether you are eating 3 ounces of chicken breast or 12. No rounding errors, no estimation. This approach mirrors how professional nutrition tracking works and ensures accuracy scales with your precision.
