Sugar cane can be consumed in moderation during pregnancy. Besides rich in sugar and water, sugar cane also contains various vitamins, fats, proteins, organic acids, vitamin C, vitamin B6, calcium, iron and other substances that are very beneficial to human metabolism. In addition, sugar cane contains a lot of dietary fiber, which is good for laxative and can relieve constipation during pregnancy. However, sugar cane contains high sugar content, including sucrose, fructose and glucose with a total content of 12%, which should not be consumed in large quantities. Pregnant women who consume large amounts of sugar can cause excessive weight gain and even elevated blood sugar, which may lead to gestational diabetes in the long run, affecting the health of the pregnant woman and the growth and development of the fetus. For pregnant women who are already suffering from diabetes, they should be cautious in consuming sugar cane to avoid excessive increase in blood sugar, which may affect pregnancy. As mentioned above, pregnant women can consume sugar cane, but they must control the amount. In addition, sugar cane should be consumed between meals, and the sugar cane must be fresh and hygienic, and the mouth should be rinsed in time after consumption to avoid tooth decay.
