The skins of sweet potatoes and kiwifruits?


Hello: Are the skins of sweet potatoes and kiwis nutritious and safe to consume? Thank you!

Qi Qi, 0~9 year old female. Ask Date: 2012/05/10

Dr. Shi Guimei reply Nutrition


Dear Qiqi,
Hello! If the skin of the sweet potato is thoroughly washed and cooked, and you do not find the texture unpleasant, it is possible to consume it along with the skin, which can increase fiber intake.
However, it is not recommended for children or the elderly, as it may stick to the oral mucosa and cause coughing or discomfort.
As for kiwi, it is not advisable to eat the skin, as the fuzz can trigger allergies or scratch the intestinal lining.
Wishing you a pleasant day!
Sincerely,
Dietitian Shih Kuei-Mei

More Info


Sweet potatoes and kiwi skins are indeed nutritious and can be safe to eat, but there are some important considerations to keep in mind regarding their consumption.

Sweet Potato Skins:
Sweet potato skins are rich in nutrients and dietary fiber. The skin contains a significant amount of antioxidants, vitamins, and minerals, including vitamin C, vitamin A, and potassium. The fiber found in the skin can aid in digestion and help maintain a healthy gut. Moreover, the antioxidants present in the skin can help combat oxidative stress in the body, potentially reducing the risk of chronic diseases.

When consuming sweet potato skins, it is crucial to wash them thoroughly to remove any dirt, pesticides, or contaminants. Organic sweet potatoes are a better choice if you are concerned about pesticide residues. Cooking sweet potatoes with the skin on can enhance their flavor and nutritional value, as many nutrients are concentrated in the skin.

Kiwi Skins:
Kiwi skins are also edible and contain a wealth of nutrients. The skin is rich in fiber, which can aid in digestion and promote a feeling of fullness. Additionally, kiwi skins are packed with vitamin C, vitamin E, and antioxidants, which can contribute to overall health and well-being. Some studies suggest that the skin may have higher antioxidant levels than the flesh of the fruit.

However, kiwi skins can be somewhat fuzzy and may not be appealing to everyone. If you choose to eat kiwi skins, make sure to wash them thoroughly to remove any pesticides or contaminants. For those who have sensitive digestive systems or are prone to allergies, it may be advisable to start with a small amount of kiwi skin to see how your body reacts.

Safety Considerations:
While both sweet potato and kiwi skins are generally safe to eat, individual reactions can vary. Some people may experience digestive discomfort from consuming the skins, especially if they are not used to a high-fiber diet. It is always best to listen to your body and consult with a healthcare professional if you have any concerns.

In summary, both sweet potato and kiwi skins are nutritious and can be included in your diet. They offer various health benefits, including increased fiber intake and a boost of vitamins and antioxidants. Just remember to wash them thoroughly before consumption, and consider your personal tolerance to fiber and texture when deciding whether to eat the skins. Incorporating a variety of fruits and vegetables, both with and without skins, can contribute to a balanced and healthy diet.
