The primary function of a healthy diet is to provide the body with energy and nutrients. The most healthiest forms of food that can be converted to energy are carbohydrates. Complex carbohydrates are more prone to being used as energy, and most unlikely to be stored as fats. What is advised is pregnant women should get at least 60% of the total energy required from carbohydrates. So for example, if your total calorie consumption is 2000, around 1200 should be in the form of both simple and complex carbohydrates.Simple carbs will comprise of sugar and other foods, that include powdered sugar, cakes, jam, jelly, pizzas, chocolates, processed foods, etc. So whenever you plan to combine simple and complex carbohydrates in your diet, make sure you consume more of complex carbs like whole grains, vegetables and fruits, and a small portion of simple carbs. Women tend to eat more calories during pregnancy, while supporting the 'eating-for-two' statement. The fact is that even if the mother is responsible for the nutrition and energy of the baby, the recommended intake is an extra 300 calories per day only, which takes care of the baby's requirements.
There has not been a standard recommendation for sugar intake during pregnancy. Every women will have a different rate of metabolism, and hence a fixed amount of sugar intake cannot be advised for all women in pregnancy. What experts suggest is that, a sugar intake amount depends on the blood glucose levels of the expecting mother, and the weight gain. Women who have minimum control on the blood sugar level, should avoid intake of sugar. Whereas, women who are required to increase weight during pregnancy, can have a higher amount of sugar. It is most strongly advised to keep the sugar intake minimum, otherwise, and more so when you are pregnant. You may consider consulting a doctor if you have been advised to increase your weight during pregnancy. So even if high sugar intake during pregnancy is not harmful for you, there has to be a moderate and balanced consumption.
Remember that sugar is not only sugar in a crystalline form, what we know as brown sugar, syrups, powdered sugar, etc. There are surely harmful, but Xylose, Lactose, Dextrose, Sucrose, Fructose, Glucose, Corn syrups and sweeteners are all sugars. Processed and canned foods are also high in sugar. So when you plan to cut off the sweet delight, make sure you consider all these as well. After all, the health of your baby is the most important, so even the sweetest of carvings too, is a big and a bitter no!
