Peach
Peaches are stone fruits rich in vitamin C, fiber, and polyphenols including catechins and chlorogenic acid. They have a low-to-moderate glycemic index fresh and provide meaningful antioxidant compounds. Canned varieties in heavy syrup contain significantly more added sugar than fresh fruit.
Also known as: Prunus persica, stone fruit, drupe

Peaches (Prunus persica) are stone fruits native to China and now grown widely in temperate regions including North America, Europe, and the Mediterranean. They are consumed fresh, canned, dried, or processed into juices and preserves. A medium fresh peach (150 g) contains approximately 59 calories, 2.4 g fiber, 0.4 g fat, and 1.4 g protein.
A medium peach provides approximately 11–15% of the daily value for vitamin C (depending on reference DV used) and contains polyphenolic compounds including catechins, quercetin, chlorogenic acid, and caffeic acid. Fresh peaches are low in resistant starch. Canned peaches in heavy syrup contain added sugars; those packed in juice or water contain lower free sugar content. The fiber in peach skin supports normal bowel function when consumed whole.
Blood Sugar and Glycemic Response
Fresh peaches have a glycemic index (GI) of approximately 42–56 depending on ripeness and variety, placing them in the low-to-moderate range. A single medium peach contains a moderate amount of carbohydrate and produces a modest postprandial glucose response. Canned peaches in heavy syrup exhibit a higher glycemic impact due to added sugars and should be distinguished from fresh or juice-packed varieties.
Allergens and Intolerances
Peach allergy is uncommon in the general population but occurs in individuals with birch pollen allergy (oral allergy syndrome), typically causing mild itching or tingling of the mouth. Peaches are considered high FODMAP by Monash University due to excess fructose and sorbitol content; individuals following a low-FODMAP diet should limit or avoid peaches and consult a registered dietitian. No common non-allergic food sensitivities to peach beyond FODMAP intolerance are widely documented. Peach skin may contain trace amounts of pesticide residues in conventional production; washing under running water reduces surface contaminants.
Frequently Asked Questions
Are peaches high in sugar?
A medium fresh peach contains a moderate amount of carbohydrate and a good amount of fiber, making its net carb content reasonable for a piece of fruit. Canned peaches in heavy syrup contain significantly more added sugar and should be consumed less frequently than fresh fruit.
Do peaches cause food allergy?
True peach allergy is uncommon. Oral allergy syndrome—mild mouth itching triggered by peach proteins that cross-react with birch pollen—occurs primarily in people with birch pollen allergy and is not a systemic food allergy. The reaction typically resolves once the fruit is swallowed or heated.
Should I eat peach skin?
Yes. Peach skin contains a significant portion of the dietary fiber and polyphenols. Washing under running water is sufficient for food safety. Peeling removes valuable fiber and micronutrients with no clear nutritional advantage.
Are peaches safe on a low-FODMAP diet?
Peaches are classified as high FODMAP by Monash University due to their fructose and sorbitol content. People following a strict low-FODMAP protocol to manage IBS symptoms are generally advised to avoid peaches or work with a registered dietitian to assess individual tolerance.
