It is best to choose camellia seed oil rich in cellulose and minerals. Camellia Oleifera seed oil is rich in vitamin E, which can effectively improve the skin condition of pregnant women and promote the absorption of calcium. Reasonable use of oil during pregnancy can effectively maintain the balance of body heat intake, and can effectively avoid the problem of obesity during pregnancy and postpartum. In addition, it should be noted that the oil temperature should not be too high or used repeatedly during cooking, which will easily lead to the loss of nutrients in the oil and even produce harmful substances.
