Pregnancy safety
Mayonnaise is only safe in pregnancy if it is prepared the right way
Only if made with pasteurised egg — shop-bought jars are; homemade mayonnaise beaten from raw yolks is not, unless the eggs are British Lion stamped.
Mayonnaise is an emulsion built on raw egg yolk, and egg that has not been pasteurised can carry salmonella, which in pregnancy brings severe vomiting, diarrhoea and dehydration and in rare cases miscarriage.
This is about food safety in pregnancy, not blood sugar — it applies whatever your readings look like. Confirm it with your midwife or doctor.

Mayonnaise for Gestational Diabetes
Mayonnaise is a thick, creamy condiment made primarily from an emulsion of oil, egg yolk, and an acid, typically vinegar or lemon juice. Its rich flavor and smooth texture make it a popular base for countless sauces, dressings, and spreads around the world. The type of oil used can vary, influencing the final taste and nutritional profile, with common options including canola, soybean, or olive oil. While commercially produced mayonnaise is widely available, homemade versions allow for greater control over ingredients and freshness.

0.6gIs Mayonnaise safe with gestational diabetes?
Mayonnaise is suitable for a gestational diabetes diet in strict moderation due to its profile of being very low in carbohydrates but extremely high in fat and calories. Its negligible carbohydrate content means it will not directly cause a blood sugar spike. However, its high caloric density can contribute to excessive weight gain, which is a key concern to manage during pregnancy with GD. Therefore, portion control is absolutely critical when incorporating mayonnaise into your meals.
How does Mayonnaise affect blood sugar during pregnancy?
With a glycemic index near zero, mayonnaise itself does not raise blood glucose levels. In fact, the high fat content can help slow down the absorption of carbohydrates from other foods eaten in the same meal, potentially blunting the overall post-meal blood sugar response. This effect can be beneficial, but it should not be seen as a license to consume large portions. Cooking methods do not alter its glycemic impact, as it is typically used cold.
What is a safe portion of Mayonnaise for gestational diabetes?
A strict portion of one tablespoon is recommended per serving. It is best to use a measuring spoon to ensure accuracy rather than estimating. This amount is sufficient to add creaminess and flavor to a tuna salad or as a spread on whole-grain bread without contributing excessive calories. Visually, one tablespoon is about the size of the tip of your thumb. Exceeding this portion can quickly add hundreds of calories, undermining weight management goals.
How should I combine Mayonnaise to manage blood sugar during pregnancy?
Use mayonnaise as your primary fat source for a specific meal component, not as an addition to an already fatty meal. Pair a small amount with lean protein sources, such as canned tuna in water, grilled chicken breast, or hard-boiled eggs. This combination provides protein and fat without adding carbohydrates, creating a balanced and blood-sugar-friendly meal or snack. Avoid pairing it with high-fat items like cheese, bacon, or fried foods to keep overall calorie and saturated fat intake in check.

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.
