Mayonnaise or mayo is a creamy sauce often added to sandwiches, burgers, and salads. It is prepared by mixing egg yolk with an acid, such as vinegar or lemon juice. You might relish it before pregnancy, but eating mayonnaise when pregnant warrants caution. The eggs used in mayo preparation are usually uncooked or raw. Besides, the eggs may or may not be pasteurized. Eating undercooked, raw, or unpasteurized eggs can expose you to harmful pathogens and adversely affect your health and that of your baby. Keep reading to know about the different types of mayonnaise, their safety for pregnant women, and precautions to take when consuming mayo.

Can You Eat Mayonnaise When Pregnant?

Mayonnaise is made both with egg and without it. Eggless mayonnaise contains olive oil or canola oil instead of egg as the base ingredient (1). Both types can be used during pregnancy. However, eating mayonnaise prepared with egg is considered safe if it is made of pasteurized (heat-treated) eggs. It is made of egg yolk, mixed with vegetable oil, and lemon juice or vinegar. Protein and lecithin in the egg yolk act as emulsifiers in mayonnaise (2). Commercial mayonnaise available on the non-refrigerated shelves in supermarkets is made of pasteurized eggs and is safe for consumption. Brands such as Hellmann’s and Heinz are popular varieties of mayonnaise that are safe to eat (3). However, avoid home-made mayonnaise as it is made of raw eggs, which run the risk of containing salmonella (4). Mayonnaise sold in the restaurants or food markets may be avoided unless you are sure that they use pasteurized eggs.

You can select a mayonnaise that suits your requirements of fat and calories, as the spread is made with several variations. Here are a few (5): Real mayonnaise meets the Codex Alimentarius food standards with fat content of 78.5% and egg 6%. Full-fat mayonnaise contains 65-75% fat. Light mayonnaise, as the name suggests has low fat content of 20-30% and around 3% egg. They include thickening agents such as maize starch and xanthan gum. Extra mayonnaise contains less than 10% fat and 4% egg.

Benefits Of Mayonnaise

Mayonnaise, when eaten in limited quantities, can be good for health. Here is how it can be beneficial for you. Total fat during pregnancy is required for the body in small amounts only.

Alternatives To Mayonnaise

Any variations of mayonnaise that do not contain egg are not considered to be mayonnaise in the US, as the Food and Drug Administration does not allow for their labeling in that name (14). Egg-free alternatives to mayonnaise are a great choice for pregnant women who are allergic to egg or are vegans. Brands such as Nayonaise and Vegenaise in the US, and Plamil Egg Free in the UK are famous substitutes for mayonnaise. If you love to have your sandwiches or bread with a spread but want to avoid mayo during pregnancy, opt healthier alternatives such as:

Tofu mayonnaise Almond and cashew paste spread Plain yogurt

Mustard Fat-free sour cream

Just like mayonnaise, they may be eaten if the eggs are pasteurized and are not home-made. Heating can kill infection-causing bacteria to an extent, but pregnancy is not the time to take such risks. However, it is advisable not to eat it during pregnancy as any growing bacteria can affect your health.
