Managing Diet During Pregnancy: Ensuring Proper Nutrition for Your Baby

Dietary Management for Pregnant Women

During the 32-week prenatal check-up, an ultrasound examination revealed that the fetus weighs approximately 2100g, which is considered overweight for 34 weeks.
After consuming 50g of glucose solution, my blood sugar level was measured at 159.
I then underwent a second test with 100g of glucose solution and am currently awaiting the results.
The nurse in the maternal education class advised me to control my starch intake.
Since the last glucose test, I have been consuming only soup and vegetables for my three meals, avoiding pasta and white rice.
However, I often feel hungry in the afternoon and substitute snacks with soda crackers and fruits.
I am concerned that this dietary control may not provide enough nutrition for the fetus.
Could you please advise me on an appropriate diet? Thank you.

Hello! Due to dietary issues, I will respond regarding high blood sugar during pregnancy.
Elevated blood sugar can lead to excessive sugar absorption by the fetus, resulting in rapid weight gain.
Additionally, gestational diabetes can cause high-risk complications such as miscarriage, preterm birth, pregnancy-induced hypertension, polyhydramnios, congenital anomalies, congenital heart disease, infants of diabetic mothers (IDM), and macrosomia, among others.
Therefore, strict blood sugar control is essential.
However, controlling blood sugar does not mean that one cannot consume carbohydrate-containing foods; it is important to maintain a baseline level of carbohydrates.
Foods that contain carbohydrates include grains and tubers (rice, noodles, buns, bread, cookies, red beans, mung beans, sweet potatoes, taro, yam, etc.), dairy products, and fruits.
These foods should be consumed in appropriate amounts daily to avoid spikes in blood sugar while ensuring adequate nutrition.

As for portion sizes, it is recommended that you consult a nutritionist who can design a dietary plan based on your current height, weight, pre-pregnancy weight, gestational age, fetal weight, blood sugar levels, and your physician's treatment plan.
Generally, in the later stages of pregnancy with high blood sugar, it is best to divide your meals into four to five smaller meals a day, or even more.
Each meal should include a balanced intake of staple foods, protein sources (fish, meat, beans, eggs), dairy products, vegetables, and fruits; it is not sufficient to only consume soup and vegetables.
I wish you a smooth delivery and a healthy, lovely baby! This response is provided by Dietitian Tsai Hsiu-Wen from Nantou Hospital, Department of Health.

Managing diet during pregnancy is crucial for both the mother and the developing fetus. It is essential to ensure that the mother receives adequate nutrition while also managing any potential health concerns, such as gestational diabetes, which seems to be a concern in your case given the elevated blood sugar levels after the glucose tolerance test.

Firstly, it is important to understand that during pregnancy, the nutritional needs of the mother increase significantly. This is to support the growth and development of the fetus, as well as to prepare the mother’s body for childbirth and breastfeeding. Key nutrients that should be prioritized include protein, calcium, iron, folic acid, and essential fatty acids.

In your situation, where you are experiencing elevated blood sugar levels, it is wise to follow the advice of your healthcare provider regarding carbohydrate intake. Reducing starchy foods and sugars is essential to manage blood glucose levels. However, it is equally important to ensure that you are not compromising your overall nutritional intake. Here are some recommendations to help you maintain a balanced diet while managing your blood sugar levels:
1. Balanced Meals: Instead of only consuming soup and vegetables, aim for balanced meals that include a source of protein (like lean meats, fish, eggs, or legumes), healthy fats (such as avocados, nuts, or olive oil), and fiber-rich carbohydrates (like whole grains, if tolerated). This combination can help stabilize blood sugar levels and provide essential nutrients.

2. Healthy Snacks: If you find yourself hungry in the afternoon, consider healthier snack options that are low in sugar but high in nutrients. Instead of soda crackers, which can be high in refined carbohydrates, opt for snacks like Greek yogurt (if tolerated), nuts, seeds, or cut-up vegetables with hummus. These options can provide protein and healthy fats, which can help keep you satiated.

3. Fruits and Vegetables: While fruits are healthy, some can be high in sugar. Focus on low-glycemic fruits such as berries, apples, or pears, which can provide vitamins and fiber without causing significant spikes in blood sugar. Incorporating a variety of colorful vegetables can also ensure you are getting a wide range of vitamins and minerals.

4. Hydration: Staying hydrated is essential during pregnancy. Water is the best choice, but you can also include herbal teas or infused water with slices of lemon or cucumber for variety. Avoid sugary drinks, as they can contribute to increased blood sugar levels.

5. Regular Monitoring: Keep track of your blood sugar levels as advised by your healthcare provider. This will help you understand how different foods affect your glucose levels and allow you to make informed dietary choices.

6. Consult a Dietitian: If you are unsure about how to balance your diet or if you have specific dietary restrictions, consider consulting a registered dietitian who specializes in prenatal nutrition. They can provide personalized guidance based on your health status and nutritional needs.

7. Emotional Well-being: Lastly, remember that stress and anxiety can also impact your eating habits and overall health. Engage in relaxation techniques, such as prenatal yoga or meditation, to help manage stress during this important time.

In conclusion, while it is crucial to manage carbohydrate intake to control blood sugar levels, it is equally important to ensure that you are consuming a well-rounded diet that meets your nutritional needs during pregnancy. By focusing on balanced meals, healthy snacks, and proper hydration, you can support both your health and the health of your baby. Always keep an open line of communication with your healthcare team to adjust your dietary plan as needed.
