Yes. As a matter of fact, science and research have shown that pressure cooking food is healthier than other methods of cooking. This is because it is able to preserve more heat-sensitive nutrients due to its shorter cook times. For example, in the case of vegetables, the pressure cooker retains the nutrients they contain, while other methods of cooking destroy these nutrients due to exposure to excess heat. It preserves all your essential nutrients because of its rapid cooking process. Even rice cooked at a higher temperature in a pressure cooker is healthy as there is no loss of nutrients.
