Peach versus raw apple with skin: calories, macros and portion trade-offs

What exactly is being compared?

For the numbers in this guide, peach means “Peaches, yellow, raw” (USDA FoodData Central 169928). It contains 39 kcal per 100 g edible portion. This reference is raw yellow peach. Canned peach in syrup and peach cobbler should not be logged as the same preparation. Keeping that definition attached to the number prevents a plain ingredient from being mistaken for a prepared meal.

The second food is “Apples, raw, with skin (Includes foods for USDA's Food Distribution Program),” rather than an unspecified raw apple with skin dish. Preparation is part of the comparison: a raw ingredient, cooked grain, spread or complete meal is not automatically interchangeable with another food just because both appear in a calorie search.

Calories on an equal-weight basis

The comparison food is “Apples, raw, with skin (Includes foods for USDA's Food Distribution Program)” (FDC 171688), which contains 52 kcal per 100 g. At equal 150 g weights, the peach reference supplies 58.5 kcal and raw apple with skin supplies 78 kcal: a difference of 19.5 kcal. That is a calculation for these records, not a universal ranking of foods or an instruction to exchange equal portions.

The gap per 100 g is 13 kcal. Doubling both weighed amounts doubles that calculated gap; halving both halves it. This explains the table without claiming that either food has a fixed portion or that a lower-energy choice provides an identical eating experience.

Protein, carbohydrate, fat and fiber

The same 100 g reference provides 0.9 g protein, 9.5 g total carbohydrate, 0.3 g fat and 1.5 g fiber. For the illustrated 150 g portion, those amounts become 1.4 g protein, 14.3 g carbohydrate, 0.4 g fat and 2.3 g fiber. Calories and individual nutrients describe different parts of the food, so keep all of them on the same portion basis when reading the table.

For raw apple with skin, the same 100 g record reports 0.3 g protein, 13.8 g carbohydrate, 0.2 g fat, 2.4 g fiber. Read those values as a profile rather than a single score. The combination you want depends on the rest of the meal and any personal nutrition requirements.

Why the realistic portion matters

A weighed 150 g portion provides approximately 58.5 kcal: 150 × 39 ÷ 100. A smaller 75 g portion gives 29.3 kcal, while 225 g gives 87.8 kcal. These are calculated amounts of the named food, not claims about the weight of a standard piece, cup or restaurant serving.

The reference is raw yellow peach with edible flesh and skin. The pit is excluded, and the weight of one peach varies; a weighed amount avoids inventing a standard fruit size.

Compare complete dishes, not isolated ingredients

Weigh cut pieces after removing the pit. A grilled peach may be plain or brushed with a fat or sweetener, so cooking style alone does not settle its finished nutrition.

Canned peaches in syrup and a peach cobbler include a different preparation or recipe. Drained weight and retained syrup are important details when selecting an entry for a packaged product.

For an explicit ingredient example, 150 g of the named peach plus 5 g olive oil gives approximately 102.7 kcal. The peach contributes 58.5 kcal and the oil contributes 44.2 kcal. This is an illustrative two-ingredient calculation, not a tested recipe or a claim that peach is always served with oil.

A practical side-by-side review

Write down the edible grams of peach in one version and of raw apple with skin in the alternative. Include any accompanying foods that change between versions. A swap that uses different amounts of bread, dressing or topping will not have the same calorie difference as the equal-weight food comparison. Keeping the ingredients visible explains the result.

In BiteCal, start with a photo of the peach portion and the rest of the meal. Review the proposed food name, preparation, amount and visible additions before saving the calorie and macro estimate. If you already know the gram weight, use it as a check rather than accepting a visually plausible portion. A photo cannot establish a hidden oil quantity or replace the identity of a packaged product.

The nutrient figures come from USDA SR Legacy, final release April 2018. They provide a reproducible reference for the named food rather than a laboratory result for your own serving. Use the current package or restaurant information when it describes your exact product more closely. Rounding explains small differences between displayed portions; calculations here use the retained unrounded reference values.
