How the diets react
Diet Ratings
1 medium peach (~150g) contains ~14g net carbs and ~13g sugar. High sugar and carb content incompatible with ketosis maintenance.
Whole plant food, naturally vegan, good source of vitamins and minerals. No animal products or derivatives.
Unprocessed stone fruit available to Paleolithic humans. Good source of vitamins A and C, fiber, and natural sugars. Moderate sugar content acceptable in paleo diet.
Peaches are whole fruits with good fiber, vitamins, and polyphenols. They are traditional to Mediterranean regions and encouraged as part of daily fruit consumption.
Plant-derived stone fruit with high sugar and carbohydrate content. Excluded from carnivore diet as a plant food.
Whole fruit with no added ingredients. Explicitly compliant as a natural fruit allowed on Whole30.
Monash University rates peach as low-FODMAP at a limited serving of 1 medium peach (150g), but the FODMAP content is borderline. Larger portions or multiple peaches exceed thresholds due to excess fructose and polyols.
Some practitioners may be more conservative with peach portions due to polyol content (sorbitol), recommending 1/2 peach during strict elimination.
DASH-approved fruit. Good source of potassium, vitamin C, and fiber. Low sodium. Whole fruit preferred over canned in syrup.
Moderate glycemic index with moderate natural sugar. Requires careful portioning to fit Zone macros. Acceptable in limited quantities with protein/fat balance.
Moderate anti-inflammatory profile with vitamin C, carotenoids, and phenolic compounds. Beneficial but less potent than berries. Good addition to anti-inflammatory diet with reasonable antioxidant content.
Moderate fiber (1.5g per 100g), moderate natural sugar (9.5g per 100g), high water content (89%), easy to digest. Acceptable in moderation but lower fiber density than berries.
