Journal Entry: The Nutritional Profile of Cured Pork Ham
Nutritional Profile: Cured Ham, Cooked (Bone-in, Lean and Fat Trimmed to ~10-15% Fat)
This profile is based on an average cooked, cured ham, typical of a commercially available product.
I. Macronutrients & Energy (Per 100g and Standard Serving)
A standard serving is defined as 85g (approx. 3 oz).
| Nutrient | Per 100g (Approximate) | Per 85g Serving (Approximate) |
|---|---|---|
| Energy | 165 kcal (690 kJ) | 140 kcal (587 kJ) |
| Protein | 19.5 g | 16.6 g |
| Total Fat | 9.5 g | 8.1 g |
| - Saturated Fat | 3.2 g | 2.7 g |
| - Monounsat. | 4.0 g | 3.4 g |
| - Polyunsat. | 0.9 g | 0.8 g |
| Carbohydrates | 0.5 g | 0.4 g |

| Sodium | 1100 mg | 935 mg |
- Reference: USDA FoodData Central. "Pork, cured, ham, boneless, extra lean and regular, cooked" (e.g., FDC ID: 170566). Values are averaged or extrapolated from similar entries to represent a common cured ham product.
II. Key Micronutrients (Per 100g)
Vitamins:
- Thiamin (B1): 0.8 mg (70% DV)
- Niacin (B3): 5.5 mg (35% DV)
- Vitamin B6: 0.4 mg (25% DV)
- Vitamin B12: 0.6 µg (25% DV)
- Riboflavin (B2): 0.2 mg (15% DV)
Minerals:
- Selenium: 35 µg (65% DV)
- Phosphorus: 220 mg (30% DV)

III. Functional Impact
- Glycemic Index (GI): Very Low (approx. 0-5)
- Rationale: Ham is virtually carbohydrate-free.
- Glycemic Load (GL): Very Low (approx. 0)
- Rationale: Minimal impact on blood glucose levels.
- Satiety Score: High
- Rationale: Rich in protein and moderate fat content, promoting prolonged fullness. Protein's thermic effect also contributes to metabolic expenditure.
- Reference: Blundell, J. E., & Macdiarmid, J. I. (1986). Satiety and the design of foods. Proceedings of the Nutrition Society, 45(2), 173-180. (General principle reference, specific ham score varies by study design).
IV. Physical Properties
- Density:
- Cooked Ham (lean muscle): ~1.04 g/cm³
- Cooked Ham (with fat marbling): ~0.98 - 1.02 g/cm³
- Note: Density varies with fat content, water content, and processing. Leaner ham tends to be denser.
- Volumetric Contraction After Cooking:
- Typical range: 15-25%
- Factors: Primarily due to moisture loss and fat rendering. Higher initial moisture content and cooking temperature generally lead to greater contraction. Cuts with higher fat content may exhibit less volumetric contraction if fat replaces lost water.
- Reference: Data extrapolated from general meat science literature on cooking losses and density changes in muscle tissue (e.g., Meat Science journal articles, specific values vary by processing and cut).

The Manual Tracking Problem with Ham
Another Tuesday, another dive into the porcine labyrinth. Ham. Just the word conjures images: glazed, smoked, cured. A simple concept, right? A pig's leg. But nutritionally, it's a quagmire. A veritable swamp of variability that utterly confounds any attempt at accurate manual logging.
My team at NutriSnap is constantly battling these culinary shape-shifters. We're talking historical behemoths, cultural anchors, foods that have been around forever. Ham fits this perfectly. From the salt-cured wonders of Iberia, hanging in ancient bodegas like leathery, delicious stalactites, to the honey-glazed spiral hams gracing holiday tables, the sheer diversity is maddening. Imagine. Dry-cured, wet-cured, smoked, unsmoked. Fresh ham (which, ironically, isn't ham in the cured sense), deli ham, picnic ham. Each with wildly differing sodium levels. Fat content? A kaleidoscope! One slice can be lean, the next a marbled masterpiece. How is anyone meant to manually track that? It’s a fool’s errand!
A barcode on a packet of pre-sliced deli ham offers a snapshot, yes. A moment of clarity. But that's just one tiny sliver of the ham-verse. What about the leftovers from Sunday roast? The glorious, glistening hunk of smoked ham that’s been carved unevenly? Or the little bits and pieces you dice for a quiche? A few cubes, oh, maybe a cup, if you're feeling ambitious and bothered to measure. But a cup of what? How dense were those cubes? Were they fat-heavy end pieces or lean, central cuts? And the glazes! Pineapple, cherry, mustard... pure carb and sugar bombs often brushed on in varying, unquantifiable layers. The entire process becomes a guessing game. A very bad guessing game, leading to wildly inaccurate dietary data.
Our traditional methods? Utterly inadequate. "Log 3 oz of ham." Right. Was that before or after cooking? Did I trim the fat? Was it country ham, dense with salt and rich fat, or a water-added product from the supermarket? The scale helps, sure. Until you remember the volumetric contraction after cooking, the variable density. A small, dry, dense piece of prosciutto might weigh the same as a larger, spongier slice of deli ham. Volume and weight become unreliable proxies for actual nutritional content. It’s like trying to catch smoke. You think you have it, but it just slips through your fingers.
This is precisely why NutriSnap exists. This is why we're building an AI photo tracker. You simply snap a photo. Our forensic visual analysis steps in. It learns the nuances: the texture, the marbling patterns, the glaze thickness, even inferring the cut and preparation method from hundreds of thousands of meticulously tagged images. It's not perfect yet, but it’s light years beyond a person squinting at a nutrition label, trying to approximate their personal serving. The future of dietary tracking isn’t about struggling with scales and ambiguous descriptors. It's about seeing, understanding, and knowing. What a revelation.
