Nutritional & Physical Profile: Pie (Generic Fruit-Filled)
Overview
This profile focuses on a commercially prepared fruit pie (e.g., apple pie), utilizing enriched flour for the crust, as a representative example of a common pie variant. Data may vary significantly based on specific ingredients, preparation methods (homemade vs. commercial), and portioning.
Macro-Nutrient Profile
| Metric | Per 100g | Per Standard Serving (150g) |
|---|---|---|
| Calories | 237 kcal | 355.5 kcal |
| Protein | 2.31 g | 3.46 g |
| Total Carbohydrates | 33.8 g | 50.7 g |
| Sugars | ~19.5 g | ~29.3 g |
| Dietary Fiber | ~1.8 g | ~2.7 g |
| Total Fat | 10.4 g | 15.6 g |
| Saturated Fat | ~2.5 g | ~3.75 g |
| Trans Fat | ~0.1 g | ~0.15 g |
| Cholesterol | ~0.5 mg | ~0.75 mg |
| Sodium | ~230 mg | ~345 mg |
Standard serving defined as 1/8th of a 9-inch pie, approximately 150 grams.
Key Micronutrients (Per 100g)
- Vitamins:
- Vitamin A: Trace (<10 IU)
- Vitamin C: Trace (~0.5 mg)
- Thiamin (B1): 0.15 mg (from enriched flour)
- Riboflavin (B2): 0.08 mg (from enriched flour)
- Niacin (B3): 1.1 mg (from enriched flour)
- Folate (B9): 30 µg (from enriched flour)
- Minerals:
- Iron: 1.2 mg (from enriched flour)
- Calcium: 15 mg
- Potassium: 80 mg
- Magnesium: 10 mg
- Phosphorus: 50 mg
- Antioxidants: General polyphenols derived from fruit content (e.g., quercetin from apples) and wheat germ. Levels are significantly reduced post-baking.
Functional Impact
- Glycemic Index (GI): High (estimated 68-78). Primarily driven by refined carbohydrates (flour, added sugars).
- Glycemic Load (GL) per 150g serving: High (estimated 34-39). Reflects the significant carbohydrate content and rapid digestion.
- Satiety Score (0-100 scale): Moderate (estimated 55-65). While initially energy-dense, the high sugar and refined carb content may lead to a shorter feeling of fullness compared to whole-food alternatives.
Physical Properties
- Density: Approximately 0.85 - 0.95 g/cm³ (average for baked goods with fruit filling and pastry crust).
- Volumetric Contraction Post-Cooking: Net 5-10% contraction from the initial pre-baked dough/filling volume to the cooled, finished product volume, primarily due to moisture loss and starch gelatinization.

The Elusive Data Point: Why Pie Is Difficult to Track
October 26, 2023
Dr. Aria Vance, Lead Nutrition Data Scientist, NutriSnap
Pie. Just pie. My nemesis, frankly. You think a simple food item like "pie" would be, well, simple to quantify. Ha! A fool's errand. A Sisyphean task.
Its history alone is a delicious rabbit hole, spanning millennia. From ancient Egypt's honey cakes in crude crusts to Roman meat pies, savory creations long predated the saccharine delights we now crave. Elizabethan England loved a good "coffin" – a thick, non-edible crust protecting the precious filling. Mincemeat pie, shepherd's pie, chicken pot pie... the sheer, glorious diversity. It's not just a food; it's a cultural artifact, a story told in pastry and filling. Every culture has a pie. What’s in it? Who made it? That's where the nightmare begins for a data scientist.
Trying to track pie manually is like trying to nail jelly to a wall. Impossible. Frustrating. Infuriating! You pull out your kitchen scale, right? Because you're serious about your macros. Okay. What then? Is it a homemade masterpiece from Aunt Mildred, lovingly rendered with a double butter crust and hand-peeled Granny Smiths, heavy on the cinnamon? Or is it that mass-produced, convenience-store special, all high-fructose corn syrup and vague fruit-like goo, encased in a suspect, pale pastry? The nutritional profiles are galactic distances apart. One slice could be a dietary indulgence; another, an absolute caloric bomb.
Then there's the portion problem. Oh, the humanity! A barcode scanner is useless for Aunt Mildred's creation. Even for store-bought, do you really cut a perfectly uniform 1/8th? No. You don't. I don't. Nobody does! There’s the generous "I had a rough day" slice, which is practically a quarter of the pie. Then there’s the dainty "just a sliver for taste" sliver, barely a wisp. You try to log that. "One slice of pie," the app prompts. But whose slice? And what kind of pie? It's a black box. A sweet, flaky, delicious black box of utter data chaos.
This variability, this utter lack of standardization, makes traditional nutrition tracking a charade. Weighing? Measuring? Who has the time, the patience, or the sheer masochistic inclination to weigh every crumb, every dollop, every variable flake of pastry? It strips the joy from the eating experience, turning a comforting ritual into a mathematical chore. People give up. They estimate, they guess, they lie. It’s not their fault. The system is broken.
That's why NutriSnap feels like... salvation. I found it, after years of wrestling with this particular culinary enigma. Finally, an AI photo tracker that doesn't demand perfect slices or detailed ingredient lists I don't possess. You snap a picture. Just like that. Its forensic visual analysis can differentiate between a dense, buttery shortcrust and a lighter, airier phyllo. It estimates irregular portions with astounding accuracy. It understands context. Pie, finally, is no longer an untrackable enigma. It's a solvable problem. Thank goodness.
