“In most cases, this is associated with the vitamins that have been washed away in the water.” Therefore, if you boil them for an excessive amount of time, you will destroy some of the nutrients.
Do vegetables retain their nutritional value after being cooked?
During the cooking process, some of the vitamins that are water-soluble are destroyed.
In point of fact, cooking veggies can diminish the amount of water-soluble vitamins by as much as fifty to sixty percent ( 7 , 9, 11 ). Cooking can also cause the loss of vitamin A and some minerals, although this happens to a much smaller level.
How can vegetables be prepared without losing their nutrients?
When everything else fails, turn to the microwave. This is due to the fact that microwaving uses very little to no water and can heat the vegetable very rapidly, which helps to preserve nutrients such as vitamin C that degrade when the vegetable is cooked. The majority of vegetables may be prepared well by sautéing them in a small amount of a nutritious cooking oil, such as extra-virgin olive oil.
Are antioxidants destroyed during cooking?
They determined the total quantity of antioxidants in the food both before and after it was cooked.
