Root vegetables

Root vegetables are a group of plants whose main edible part is the root. This group, which includes carrots, beets, parsley, parsnips, celery, and others, is a significant source of vitamins, minerals, and fiber. These vegetables are rich in antioxidants, which help protect the body against harmful free radicals. The fiber contained in root vegetables supports digestive health and can help prevent constipation. They are also a rich source of potassium, which supports heart health.

When root vegetables are roasted in the oven with oil, is it appropriate? Is there a difference in the preservation of nutrients compared to traditional sautéing of root vegetables with oil in a pot on the stove? What do you recommend?

Cooking vegetables in oil is acceptable until the oil burns. Therefore, it is necessary to control the temperature during baking, sautéing, or frying. When using water instead of fat, a lower temperature is generally set, which results in a smaller proportion of some undesirable substances (e.g., acrylamides) in the ingredients.
