Air potato, also known as Dioscorea bulbifera, is a type of yam that is native to Asia and Africa. It is an edible tuber that has become an invasive plant species in many parts of the world. There has been some debate over whether air potato is beneficial or harmful to human health.
Nutritional content of air potato
Air potatoes contain a number of nutrients that can contribute to a healthy diet. According to the USDA, a 100 gram serving of raw air potato contains:
- 24 calories
- 0.1 grams of fat
- 5.8 grams of carbohydrates
- 0.5 grams of fiber
- 0.9 grams of protein
- 11% of the RDI for vitamin C
- 8% of the RDI for vitamin B6
- 5% of the RDI for potassium
- 4% of the RDI for magnesium
Air potatoes are a good source of vitamin C, an antioxidant that helps promote immune health and iron absorption. They also contain vitamin B6, potassium, and magnesium. Potassium supports heart health and fluid balance, while magnesium aids bone health and nerve functioning.
Potential health benefits
Here are some of the potential health benefits associated with consuming air potatoes:
May boost immunity
The vitamin C content in air potatoes acts as an antioxidant to strengthen immune defenses against pathogens and infection. Vitamin C also helps the body absorb iron more efficiently, preventing anemia.
May promote heart health
With their potassium, vitamin B6, and magnesium content, air potatoes may help reduce blood pressure, decrease cholesterol, and lower heart disease risk.
May support digestion
The fiber in air potatoes acts as a prebiotic to feed probiotics in the gut. This helps promote regularity, prevent constipation, and maintain a healthy microbiome.
May stabilize blood sugar
Despite being a starchy vegetable, air potatoes have a low glycemic index. This means they may help regulate blood sugar levels and reduce complications related to diabetes.
Potential health risks
However, there are also some potential downsides to eating air potatoes:
Allergenic compounds
Air potatoes contain allergenic proteins that can trigger reactions in people sensitive to latex, kiwi, avocado, banana, chestnut, and more. This is called latex-fruit syndrome.
Toxic oxalates
Air potatoes have moderate amounts of oxalates, compounds that can bind to calcium and cause kidney stones in susceptible individuals.
Gastrointestinal distress
Overconsumption of undercooked air potatoes may lead to gas, bloating, diarrhea, and other gastrointestinal symptoms.
Cyanide poisoning
Like other root vegetables, air potatoes contain trace amounts of cyanide. Eating large quantities of raw, unprocessed air potato can potentially be fatal.
How to eat air potatoes safely
You can take the following precautions when consuming air potatoes:
- Cook air potatoes thoroughly before eating.
- Limit portion sizes to 1-2 medium air potatoes per meal.
- Drink plenty of water to flush out oxalates.
- Avoid air potatoes if you have latex allergies or kidney issues.
- Consume air potatoes in moderation as part of a balanced diet.
