Tag: Cooked vs raw onions

According to the National Onion Association, the average person consumes over 20 pounds of this versatile vegetable annually, preparing them in countless ways. While raw and sauteed onions are common, the question remains: is it healthy to eat boiled onions, and how does this cooking method affect their nutritional value?

According to a study published in the *International Journal of Current Microbiology and Applied Sciences*, heating vegetables can cause significant losses of Vitamin C. So, does cooking onions reduce vitamin C content in the same way? The short answer is yes, but the extent of the loss depends heavily on your cooking method.

According to the USDA, a raw onion is roughly 9–10% carbohydrates by weight, but how many carbs are in one cooked onion can differ due to water loss. Understanding this concentration is key for those monitoring their carbohydrate intake, especially on a keto or low-carb nutrition diet.
