How to Calculate Calories in Onions?
If you want to know the exact number of calories in your onion preparation, you can use a simple calculation. First, weigh your onions in grams.

To preserve the nutritional content of your onions, it's essential to store them properly. Onions should be stored in a cool, dry, and well-ventilated area to prevent mold growth and premature spoilage. Avoid storing onions in plastic bags or in the refrigerator, as this can accelerate spoilage and reduce their shelf life. If you have cut onions that you need to store for later use, be sure to wrap them tightly in plastic wrap or foil to prevent the loss of moisture and nutrients.
Onion Consumption and Possible Side Effects
Although onions offer numerous health benefits, it's important to be aware of the potential side effects associated with overconsumption. Some people may experience digestive issues, such as bloating, gas, or diarrhea, after eating onions. Additionally, some people may be allergic to onions and experience symptoms such as itching, swelling, or difficulty breathing.
