Introduction

Winter hancai usually refers to winter mallow. Under normal circumstances, winter mallow can provide some vitamin C, but its content is limited, so it should be consumed together with other foods. When cooking winter mallow, it is recommended to stir-fry quickly or serve cold to minimize the loss of vitamin C. In daily life, maintaining a diversified diet and reasonably combining various ingredients can more comprehensively supply the vitamin C required by the body.

"Winter cold vegetable" usually refers to Malva verticillata. Under normal circumstances, Malva verticillata can supply some vitamin C, although its content is limited, so it should be consumed together with other foods. Detailed explanation is as follows:

Malva verticillata is one of the vegetables containing vitamin C, and moderate consumption can provide a certain amount of vitamin C for the body. Vitamin C is an essential nutrient for the human body, participating in various physiological processes and playing an important role in maintaining health. In addition to vitamin C, Malva verticillata also contains dietary fiber, minerals, and other nutrients that provide comprehensive nutritional support for the body.

However, the vitamin C content in Malva verticillata is not particularly high, and vitamin C is easily destroyed by high temperatures. Improper cooking methods may lead to vitamin C loss. Relying solely on Malva verticillata to supply vitamin C may not meet the daily needs of the human body. Therefore, when consuming Malva verticillata, it can be combined with other fresh vegetables and fruits rich in vitamin C, such as green peppers, kiwifruit, etc.

It is recommended to cook Malva verticillata quickly by stir-frying or serving it cold to minimize vitamin C loss. In daily life, maintaining a diversified diet and rationally combining various ingredients can more comprehensively supplement the vitamin C required by the body and maintain normal bodily functions.
