IVF foods to avoid: Dietary Choices to Skip During Treatment

Quick Overview

This blog includes information on IVF foods to avoid during IVF treatment, that includes alcohol, raw foods, high-mercury fish, caffeine and more. It also explains what to eat during IVF, food safety after embryo transfer, and whether diet can actually affect IVF success. 

Introduction

Foods play an important role in overall health during an IVF journey. While no food can guarantee IVF success, eating a healthy diet can support general health and help the body with its nutritional needs during treatment. 

At the same time, several foods and drinks are avoided during IVF journey, because of concerns of food safety, excessive sugar, unhealthy fats, etc. 

Why Does Diet Matter During IVF?

IVF involves multiple stages such as stimulation, egg retrieval, fertilization, embryo development and embryo transfer. During this period, the body goes through several hormonal and physical changes and a healthy diet provides required nutrients.

A healthy diet provides important nutrients such as protein, fiber, minerals, vitamins and healthy fats. However, it is important to understand that diet alone does not determine IVF success. Factors such as age, egg quality, sperm health, reproductive health, embryo quality, etc also play a major role. People must know IVF foods to avoid that could help in pregnancy.

The goal should be to follow a balanced diet rather than focusing on single fertility food.

Foods To Avoid During IVF

There are multiple IVF foods to avoid. Those are:

• Alcohol

Alcohol must be avoided during fertility treatment, especially around embryo transfer and when pregnancy is around.

Regular alcohol consumption can affect overall health and may have a negative impact on fertility. Once pregnancy is confirmed, alcohol must be avoided fully as there is no known amount of alcohol during pregnancy.

1. High-Mercury Fish

Fish is an excellent source of energy that contains omega-3 fatty acids and protein but some fish contain high levels of mercury.

High mercury exposure can be harmful during pregnancy and can damage the developing nervous system.

Examples of fish that should be avoided during IVF treatment. Those are:

• Marlin
• Swordfish
• Shark
• King mackerel
• Orange roughy

You need not to stop eating all the fish during IVF treatment. You can choose fish with lower mercury that can help in providing required nutrients to the body.

• Raw or undercooked seafood

Raw or undercooked seafood may contain harmful bacteria, viruses or parasites.

Some of the examples are:

• Raw fish
• Sushi containing raw seafood
• Raw shellfish
• Undercooked prawns

During IVF, especially after embryo transfer and when pregnancy is possible, choosing properly cooked seafood is a safer option. One must know IVF foods to avoid during treatment or pregnancy. 

• Raw or undercooked meat

Raw or undercooked meat could contain microorganisms that could cause foodborne illness.

During fertility treatment and early pregnancy, it is better to eat proper cooked meat. Avoid dishes containing raw or undercooked meat, and make sure meat is stored and handled safely..

• Unpasteurized milk and dairy products

Unpasteurized milk and products made from it may contain Listeria. Choose pasteurized milk, yogurt, cheese and other dairy products during IVF or pregnancy.

Always check food labels when you are unsure whether the product is pasteurized.

• Raw eggs and foods containing them

Raw or undercooked eggs can carry salmonella. During IVF and early pregnancy, it’s safer to consume properly cooked eggs. 

Be cautious with foods that may contain raw eggs such as homemade mayonnaise, raw cookie doughs or some dessert.

• Processed and highly packaged food

Highly processed foods are high in sugar, salt, refined carbohydrates and unhealthy fats while providing fewer essential nutrients.

Examples include:

• Chips
• Packaged snacks
• Sugary cereals
• Instant noodles
• Fast food

Eating these occasionally is unlikely to affect IVF, but making it a regular habit can make it harder to maintain a balanced diet. 

• Foods high in added sugars

Excessive intake of sugary foods and drinks can contribute to excessive calorie intake and blood sugar fluctuations.

Limit foods such as:

• Soft drinks
• Candy
• Cakes
• Pastries 
• Cookies

You do not need to completely eliminate naturally occurring sugars in fruits and dairy products. Focus mainly on reducing foods and beverages with large amounts of added sugar.

• Excessive caffeine

Caffeine does not have to be necessarily eliminated during IVF, but excessive consumption is not recommended, especially when pregnancy is confirmed. Caffeine could be found in coffee, tea, cola, energy drinks, etc.

Several pregnancy guidelines suggest keeping caffeine intake to 200 mg/day or less during pregnancy.

• Unwashed fruits or vegetables

Fresh fruits and vegetables are the most important part of a balanced diet, but they should be washed properly before eating.

Unwashed produce may carry microorganisms from soil or handling.

These were some IVF foods to avoid that can help in enhancing your IVF treatment.

What to eat during IVF treatment?

Instead of concentrating on IVF foods to avoid, you should focus on creating a balanced diet. 

You should include:

• Protein: Choose eggs, beans, lentils, dairy products, chicken, fish which are low in mercury in your diet.
• Fruits and vegetables: Include fruits and vegetables in your diet to obtain vitamins, minerals, fiber, etc.
• Whole grains: Brown rice, oats, whole-wheat roti could provide fiber and other essential nutrients.
• Healthy fats: Nuts, seeds, avocados, and suitable vegetable oils can provide unsaturated fats. 
• Plenty of fluids: Water is an important part of maintaining hydration. Your individual fluid needs may vary depending on your health, activity level, and treatment. 

As we keep a track on IVF foods to avoid, it is also important that a proper nutritious food should be consumed during IVF treatment.

Conclusion

Knowing IVF foods to avoid could help you make safer and healthier choices throughout the treatment. Alcohol, raw foods, highly processed foods, unpasteurized dairy products, excessive caffeine, etc must be avoided during IVF treatment or pregnancy. 

At the same time, there is no need to follow an unnecessarily restrictive diet. A balanced eating pattern that includes vegetables, fruits, whole grains, protein, healthy fats, and adequate fluids is a sensible approach.
