Eating fruit with the peel helps replenish fiber, vitamins, minerals, and beneficial plant compounds.
Below are fruit and vegetable peels you should keep and consume safely.
Apples
Apple skin is safe to eat and contains most of the fruit's fiber. Keeping the skin on nearly doubles the fiber intake compared to peeled apples.
Fiber supports digestion, promotes prolonged fullness, and aids in weight management. Orange peel also contains antioxidants, including quercetin, which helps protect cells, inhibits harmful bacteria, and supports gut health.
Kiwi
Eating kiwi with the skin provides extra fiber and antioxidants. Studies show that golden kiwi skin helps increase fiber intake by about 50%.
The skin of this fruit also contains vitamins C and E, which support immunity and protect cells. If you mind the fuzzy texture, you can wipe it clean with a cloth or choose golden kiwi for easier eating.
Peach
Peaches provide an abundance of vitamins A and C, fiber, and antioxidants. Most of these nutrients are concentrated in the soft, fuzzy skin. The peel of this fruit contains chlorogenic acid, which helps fight inflammation and supports lowering blood pressure and cholesterol levels.
Potatoes
Potato skins contain many vital nutrients and antioxidant compounds. Keeping the skin on when baking adds about 1.5 grams of fiber. This slows down carbohydrate digestion and helps stabilize blood sugar.
Compared to peeled potatoes, potatoes baked with their skin provide three times more iron and 35% more potassium.
Watermelon
Watermelon rind is safe to eat and packed with fiber and citrulline, an amino acid that supports blood circulation and cardiovascular health. The white rind is often cooked, pickled, or blended into smoothies for added nutrition.
Orange
Orange peel is edible, but it tastes quite bitter. Zest is often used in recipes rather than eaten directly. One tablespoon of orange peel provides about 9% of the daily vitamin C requirement. It is also rich in flavonoids and limonene, which help fight inflammation and protect brain cells.
Banana
Banana peel contains fiber, potassium, and antioxidants such as carotenoids and flavonoids. These compounds help protect cells and support gut health. The antioxidant content increases as the banana ripens.
The skin of this fruit also contains tryptophan, an amino acid that supports mood and sleep.
Grapes
Grape skins are very rich in fiber and antioxidants. Red grape skins contain high levels of resveratrol, which helps lower the risk of heart disease and certain cancers. This compound also supports weight and blood sugar management.
Carrots
Carrot peel contains more minerals and antioxidants than the inner flesh. The beta-carotene in the peel is converted by the body into vitamin A, which is good for vision and skin health.
Cooking helps break down plant cell walls, making it easier for the body to absorb nutrients.
Onions
Onion skins are rich in fiber and antioxidants. Red onion skin is especially high in anthocyanins, which help reduce inflammation and benefit the heart, liver, and brain. You should use onion skins when making soups or stocks rather than eating them raw.
How to eat fruit and vegetable peels safely
The outer surface can harbor dirt, bacteria, and pesticide residues. You should wash fruits and vegetables thoroughly under running water right before eating or cutting them.
You can even use a clean brush to scrub firm-skinned produce like potatoes or carrots. Be sure to cut away bruised areas before eating and prioritize organic produce to ensure safety.
