Certain vegetables, such as potatoes, carrots, and cucumbers, are best enjoyed with their skin intact to preserve their full range of nutrients and health benefits.

According to Healthshots, here are five vegetables you should avoid peeling to get the most out of their nutritional value.

1. Potato

While peeling potatoes is common, you might want to reconsider. Potato skins are rich in fiber, vitamins, and minerals. In fact, the highest concentration of fiber in a potato is found in the skin, according to Healthline.

Additionally, potato skin contains more potassium than the flesh, which is crucial for heart health and muscle function. It is also packed with iron, which supports the function of red blood cells.

Therefore, keeping the skin on adds texture and boosts the nutritional value of your potato dish. Just be sure to wash them thoroughly before cooking.

2. Carrot

Carrot skin is not only safe to eat, but it also provides several key nutrients. It is rich in antioxidants, vitamin C, B3, dietary fiber, and phytonutrients, all of which are vital for immune health and maintaining healthy skin and eyesight.

3. Cucumber

Many people peel cucumbers, but the skin holds a wealth of nutrients, including fiber, vitamins, and minerals. Cucumber skin is particularly rich in vitamin K, which is essential for blood clotting and bone health. It also contains silica, which supports the health of your skin, hair, and nails.

4. Eggplant

Eggplant is a flavorful vegetable, and its skin offers important health benefits. The skin is packed with nasunin, a powerful antioxidant that helps protect brain cells from oxidative stress.

It also contains dietary fiber, which supports digestion and helps you feel full, aiding in better control of your food intake.

5. Zucchini

Zucchini is another vegetable that should be eaten with the skin on. Both the flesh and the peel are loaded with health benefits, including improved digestion, better mood, and stronger bones. The skin is especially high in dietary fiber, vitamin C, and potassium.
