Pregnancy safety
Limit how much Monkfish you eat during pregnancy
No more than one serving (about 115 g) a week.
Monkfish is on the FDA/EPA "Good Choices" list at one serving a week, as its methylmercury level is higher than the small whitefish that can be eaten two or three times a week in pregnancy.
This is about food safety in pregnancy, not blood sugar — it applies whatever your readings look like. Confirm it with your midwife or doctor.

Monkfish for Gestational Diabetes
Monkfish is a unique-looking bottom-dwelling fish known for its delicious tail meat, which has earned it the nickname 'the poor man's lobster'. Its flesh is firm, dense, and succulent with a mild, slightly sweet flavor that is not overly fishy. Unlike flakier fish, monkfish has a meaty texture that holds its shape well during cooking, making it incredibly versatile. The edible part is primarily the tail, as the head is disproportionately large and typically discarded. It is a popular choice in gourmet cooking due to its luxurious texture and taste.

0gIs Monkfish safe with gestational diabetes?
Monkfish is an outstanding choice for managing gestational diabetes due to its zero-carbohydrate and high-protein content. This nutritional profile ensures it has no direct impact on blood glucose levels, making it a very safe food. The high-quality protein promotes satiety, which helps with appetite control and prevents overeating high-carbohydrate foods. Furthermore, it is a source of omega-3 fatty acids, which are beneficial for both maternal health and fetal brain development. Its lean nature makes it a healthy addition to any meal plan.
How does Monkfish affect blood sugar during pregnancy?
With a glycemic index of zero, monkfish does not cause any rise in blood sugar when consumed on its own. The significant protein content actively helps to stabilize blood sugar by slowing down the absorption of carbohydrates from other foods in the same meal. Cooking methods are key; grilling, baking, or steaming preserves its low glycemic impact. Avoid breading and deep-frying, as the coating adds unnecessary carbohydrates and unhealthy fats that can negatively affect blood sugar control and overall health.
What is a safe portion of Monkfish for gestational diabetes?
A suitable portion of monkfish is a fillet about the size and thickness of your palm. This provides a generous amount of protein to anchor your meal and promote fullness without being excessive. Visually gauging your portion helps maintain consistency without needing a scale for every meal. Be mindful of sauces and marinades, opting for simple herbs, lemon juice, and spices instead of sugary glazes that could introduce hidden sugars and counteract the benefits of the fish.
How should I combine Monkfish to manage blood sugar during pregnancy?
To create a balanced, blood-sugar-friendly meal, pair monkfish with high-fiber carbohydrates and non-starchy vegetables. A serving of quinoa, a small portion of sweet potato, or a large salad provides sustained energy without sharp glucose spikes. The protein in the monkfish will blunt the glycemic response of these carbohydrates. Healthy fats, such as a drizzle of olive oil or a side of avocado, can further aid in blood sugar stabilization and increase nutrient absorption from the vegetables.

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.
