Is there a benefit to eating mango skin?

Research indicates that mango skin is loaded with higher concentrations of antioxidants like polyphenols and carotenoids compared to the fruit's flesh. But is there a benefit to eating mango skin that outweighs its unpleasant texture, bitter taste, and potential for allergic reactions?

Quick Summary

Mango skin is edible and packed with nutrients, including high fiber and potent antioxidants, but can cause allergic reactions in sensitive individuals due to urushiol. The bitter taste and tough texture also make it unappealing, though it can be prepared in ways that minimize these downsides.

Key Points

• Nutrient-Dense Skin: Mango peel is a potent source of fiber, antioxidants, and vitamins, with research showing it can have higher concentrations of beneficial compounds than the flesh.

• Contains Urushiol: A major risk of eating mango skin is the presence of urushiol, the same allergen found in poison ivy, which can cause severe allergic reactions in sensitive people.

• Potential Health Perks: The high fiber and antioxidant content may contribute to better digestive health, weight control, and protection against certain chronic diseases like diabetes and cancer.

• Mitigate the Taste: To overcome the bitter taste and tough texture, mango skin can be blended into smoothies, dried and powdered, or used to make teas and chutneys.

• Choose Organic and Wash Thoroughly: To reduce exposure to pesticides that can accumulate on the peel, it is highly recommended to eat organic mango skin and to wash it meticulously.

• Consider the Trade-off: The nutritional benefits of mango skin are notable, but so are the risks and palatability issues, meaning the choice to consume it depends on individual health, allergies, and preference.

The Surprising Nutritional Profile of Mango Skin

While most people discard the peel, the skin of a mango (Mangifera indica) is a nutritional powerhouse often overlooked. The peel contains a dense concentration of vitamins, minerals, and potent plant compounds that are beneficial to human health. In fact, some studies show that mango peel extract exhibits stronger antioxidant and anticancer properties than the flesh.

Key Nutrients Found in Mango Peel

• Dietary Fiber: Mango skin is exceptionally rich in fiber, making up a significant portion of its weight. This fiber is crucial for promoting healthy digestion, regulating bowel movements, and increasing feelings of fullness, which can support weight management.
• Antioxidants: The peel contains high levels of various antioxidants, including polyphenols, carotenoids, and vitamin E. These compounds help combat oxidative stress in the body by neutralizing free radicals that can damage cells and contribute to chronic diseases.
• Polyphenols: Specific polyphenols found in mango skin, such as mangiferin and quercetin, have been shown to have anti-inflammatory, anti-diabetic, and anti-carcinogenic properties.
• Vitamins: The skin provides a notable amount of Vitamin C, which is essential for immune function, and Vitamin E, which protects cells from damage.
• Triterpenes and Triterpenoids: These compounds present in the skin have demonstrated potential anticancer and antidiabetic qualities in test-tube studies.

Potential Health Benefits of Consuming Mango Peel

Integrating mango skin into one's diet, either directly or as a powdered supplement, could offer several health advantages. Research on the benefits is ongoing, but initial findings are promising.

• Anticancer Properties: Test-tube studies have indicated that mango skin extracts possess anti-proliferative properties against certain cancer cells. The high antioxidant content is a primary driver of this potential benefit.
• Diabetes Management: The fiber in mango peel can help regulate blood sugar levels, making it a valuable addition to a diet focused on controlling diabetes. Some compounds, like mangiferin, have also been researched for their antidiabetic effects.
• Weight Control: The high fiber content promotes satiety and can aid in appetite control, which is a key factor in weight management. Additionally, some research suggests mango peel may help inhibit the formation of fat cells.
• Improved Digestive Health: The high amount of both soluble and insoluble fiber in mango peel supports a healthy gut microbiome and promotes regularity, aiding overall digestive function.
• Skin Health: The vitamin C, vitamin E, and carotenoids act as antioxidants to protect skin from oxidative damage and promote a healthy glow.

Risks and Downsides to Consider Before Eating

While the nutritional profile is impressive, eating mango skin is not without its drawbacks and risks. These are often the reasons people choose to peel the fruit.

• Allergic Reactions (Urushiol): The most significant risk is the presence of urushiol, an oily chemical cocktail also found in poison ivy and poison oak. For sensitive individuals, consuming mango skin can cause an itchy rash, swelling, or contact dermatitis around the mouth. People with a known sensitivity to poison ivy or poison oak should avoid mango skin entirely.
• Pesticide Residue: Standard mangoes are often treated with pesticides. The peel is where these residues are most likely to accumulate. Thoroughly washing, or better yet, choosing organic mangoes, is essential to mitigate this risk if you plan to eat the skin.
• Unpleasant Taste and Texture: Many people find the taste of mango skin to be bitter and the texture fibrous, tough, and chewy. This can detract from the enjoyable experience of eating the sweet, tender flesh.
• Digestive Discomfort: The high fiber content can be difficult for some people to digest, potentially leading to bloating, gas, or other stomach discomfort. It is best to start with small amounts to see how your body reacts.

Mango Skin vs. Mango Flesh: A Comparison

To fully understand the trade-offs, here is a comparison of the key characteristics of mango skin and mango flesh.

Feature	Mango Skin	Mango Flesh
Antioxidant Content	Significantly higher concentrations of polyphenols and carotenoids.	Lower concentration, but still a good source.
Fiber Content	Exceptionally high, comprising a large portion of the peel's weight.	High in fiber, especially soluble fiber, but less dense than the peel.
Taste	Bitter, fibrous, and tough.	Sweet, juicy, and flavorful.
Texture	Leathery, tough, and difficult to chew.	Soft, tender, and pulpy.
Allergen Presence	Contains urushiol, potentially causing allergic reactions in sensitive people.	Contains minimal to no urushiol in peeled form, generally safe.
Pesticide Risk	Higher risk of residue accumulation if not organic.	Lower risk, as the peel is discarded, but still requires washing.

How to Safely and Palatably Consume Mango Skin

If the potential benefits intrigue you and you are not sensitive to urushiol, there are ways to incorporate the skin into your diet that minimize its negative qualities.

• Blend into Smoothies: This is one of the easiest ways to mask the texture and bitterness of the skin. Blend a well-washed, skin-on mango with other ingredients like banana, pineapple, or yogurt.
• Make Powder: Dry the mango peels in the sun or a dehydrator, then grind them into a fine powder. This powder can be added to smoothies, yogurt, or baked goods to boost nutritional content.
• Infuse Water or Tea: Add strips of clean mango peel to boiling water for a subtle flavor infusion. You can also add other flavorings like ginger or cinnamon.
• Create Chutney or Pickles: In some cultures, mango peels are used in traditional chutneys or pickles. Cooking and seasoning the peels can make them more palatable.
• Choose Organic: Always opt for organic mangoes if you plan to eat the skin to minimize exposure to pesticides and other chemical residues.

Conclusion

In summary, there is a clear nutritional benefit to eating mango skin, as it contains higher concentrations of dietary fiber and potent antioxidants than the fruit's flesh. These compounds contribute to various potential health benefits, including supporting digestive health, weight management, and offering antioxidant, anti-inflammatory, and potentially anticancer properties. However, the decision to eat mango skin is a personal one that involves weighing these benefits against significant drawbacks, including a potentially unpleasant taste and texture, the risk of pesticide residue, and the possibility of a serious allergic reaction due to urushiol. For individuals with a sensitivity to poison ivy or similar plants, eating mango skin is not recommended. For others, safely consuming the skin, perhaps in a smoothie or as a powder, can be a way to maximize the fruit's nutritional potential while minimizing waste. For comprehensive health advice, it's always best to consult with a medical professional. Read more on the topic from Healthline.
