Onions are a staple in almost every household. They are especially vital in preparing gravies and vegetables, and are often consumed raw in salads. Onions have proven benefits in reducing the risk of heart attacks, and the prebiotic compounds in them support the growth of beneficial gut bacteria, aiding digestion. (News18 Gujarati)

The black spots seen on onions are actually a type of fungus, scientifically known as Aspergillus niger. This fungus is commonly found in soil. Though it is not as dangerous or fatal as some other black fungi, it is still not completely safe for consumption. (News18 Gujarati)

Aspergillus niger can be particularly harmful to individuals with allergies. Consuming onions affected by this fungus may lead to respiratory problems, skin irritations, or even weaken the immune system over time. (News18 Gujarati)

Because of these potential health risks, it is essential to check onions thoroughly before using them. If black spots are noticed, the onion should either be discarded or washed very carefully to minimise exposure to the fungus. (News18 Gujarati)

Proper handling and inspection of onions can help prevent unwanted health issues. Being cautious about visible signs of spoilage or fungal growth ensures that the food you eat remains both safe and nutritious. (News18 Gujarati)
