Pregnancy safety
Limit how much Vietnamese Coriander (Rau Ram) you eat during pregnancy
A garnish-sized few leaves in a dish rather than a generous raw handful, and preferably not in the first trimester.
Rau ram is traditionally avoided in early pregnancy in Vietnam because of a long-standing abortifacient reputation, and there is no safety data for eating it raw in large quantities.
This is about food safety in pregnancy, not blood sugar — it applies whatever your readings look like. Confirm it with your midwife or doctor.

Vietnamese Coriander (Rau Ram) for Gestational Diabetes
Vietnamese coriander, known as Rau Ram, is a perennial herb with a distinct and potent flavor profile. It offers a unique combination of spicy, peppery, and citrusy notes, often compared to a more intense version of cilantro but with a lemony twist. This herb is a staple in Southeast Asian cuisine, particularly in Vietnamese and Malaysian dishes, where it adds a signature fresh and zesty kick. Botanically known as *Persicaria odorata*, its leaves are slender and dark green with characteristic chestnut-colored markings. It is prized for its ability to cut through the richness of meats and seafood.

6.1gIs Vietnamese Coriander (Rau Ram) safe with gestational diabetes?
Vietnamese coriander is a useful herb for a gestational diabetes meal plan. It provides a burst of flavor to meals without adding any sugar or significant carbohydrates, helping to make compliant eating more enjoyable. Its nutritional profile includes beneficial vitamins and antioxidants without any risk to blood glucose control. Using herbs like Rau Ram can reduce the reliance on high-sugar or high-sodium sauces and dressings. In pregnancy it is the quantity that changes: a few leaves as a garnish is the traditional culinary use and the one to stay with, while the generous raw handfuls some salads call for are best avoided, particularly in the first trimester.
How does Vietnamese Coriander (Rau Ram) affect blood sugar during pregnancy?
The impact of Vietnamese coriander on blood sugar levels is negligible, making it an ideal ingredient for managing gestational diabetes. With a very low carbohydrate count and a decent amount of fiber, it does not cause any spikes in blood glucose. Its glycemic index is extremely low and can be consumed freely without concern for glycemic load. Cooking methods do not alter its glycemic properties, as it is not a starchy food. You can confidently add it to any meal to enhance flavor without needing to account for it in your carbohydrate counting.
What is a safe portion of Vietnamese Coriander (Rau Ram) for gestational diabetes?
Carbohydrate is not what limits Vietnamese coriander during pregnancy; the amount is. A garnish-sized few leaves, torn over a bowl of pho, a salad or a plate of grilled meat, is the portion to work with rather than a generous raw handful. In the first trimester it is worth leaving out altogether and reaching for mint, cilantro or Thai basil instead, which give a similar fresh lift with no such history behind them. At garnish scale it still has no measurable effect on your blood sugar, so it remains a good way to liven up meals without spending any of your carbohydrate budget.
How should I combine Vietnamese Coriander (Rau Ram) to manage blood sugar during pregnancy?
Rau Ram is a versatile herb for creating balanced, GD-friendly meals. Pair it generously with lean protein sources such as grilled chicken breast, steamed fish, or baked tofu to create flavorful and satisfying main courses. Its zesty flavor profile beautifully complements these proteins, reducing the need for sugary marinades. You can also toss it into salads with non-starchy vegetables and a healthy fat source like avocado or a light vinaigrette. This pairing strategy ensures a nutrient-dense meal with minimal impact on blood sugar levels while providing a complex and enjoyable taste.

Important Safety Information
Every pregnancy is different, and gestational diabetes is managed differently depending on your readings, your medication and how far along you are. The ratings and portions on this page are general information — not a diagnosis, a treatment plan or a medical device — and they cannot see your results.
- Low blood sugar:
- If you take insulin or diabetes medication, eating less carbohydrate than your team planned for can push your blood sugar too low. Treat a reading below 70 mg/dL (3.9 mmol/L), or symptoms such as shaking, sweating, confusion or a racing heart, with fast-acting carbohydrate immediately and retest after 15 minutes. Never use this page as a reason to skip or shrink a meal you were told to eat.
- Carbohydrate and ketones:
- Cutting carbohydrate hard to force a number down is not safe in pregnancy — it can produce ketones. Published guidance sets a minimum of 175 g of carbohydrate per day in pregnancy. Readings that stay above target for several days need your care team, not a smaller portion.
- Medication and insulin:
- The portions here are generic and know nothing about your insulin doses, your metformin, or the steroids given to mature your baby's lungs — all of which change how a meal affects you. Never adjust a dose or a mealtime based on this page.
- Food safety in pregnancy:
- Blood sugar is not the only thing that makes a food suitable while you are pregnant. Some foods with excellent glycemic numbers still carry mercury, vitamin A, listeria or alcohol risks, and those are judged separately from the ratings shown here. Check your national pregnancy food-safety guidance before adding an unfamiliar food.
- What these ratings can and cannot tell you:
- Glycemic index values, impact ratings and maximum servings are population averages taken from published tables. Two people eating the same food can get very different readings, so your own meter is the only measurement that describes you. Nutrition figures are indicative per 100 g and vary with brand, ripeness and preparation.
Contact your care team the same day if: your readings stay above target for several days; you have a reading below 54 mg/dL (3.0 mmol/L) or needed someone else's help to treat a low; you test positive for ketones; or your baby is moving less than usual. Seek emergency care for confusion, fainting, repeated vomiting, or a low you cannot bring back up.
