Is It Safe to Eat Capers During Pregnancy? (Health Claims, Nutrition)

When you are pregnant, you worry about everything you do, eat, and put on your body. Knowing what foods you can eat and what to avoid is essential in pregnancy. You may find yourself concerned about some ingredients like capers, especially if they are an item you don’t eat very often.

The good news is that capers are safe to eat during pregnancy in average amounts (about 1 Tablespoon) as an ingredient in a dish.

The sharp, lemony-olive taste of capers is a staple in Mediterranean dishes and can bring a delightful addition to your diet.

While some people may use foods for their medicinal benefits, capers are not recognized as a medication. Therefore if you intend on using them as medication for more than seasoning food, you should discuss it with your doctor. 

Continue reading for details about what capers are, how capers may affect a body when taken in greater doses than in a recipe, and some recipes you can make at home to try out capers.

Capers Are Safe To Eat During Pregnancy

If you have been searching on the internet for some information about whether or not capers are safe, you might become alarmed as you read.

We want to clarify some information for you. 

The Natural Medicines Comprehensive Database compiles data on foods and other plants and their effectiveness as medicines.

They rank different items according to their safety with the following labels: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate.

This website does require a subscription to access the database. 

Capers are a commonly used ingredient in Italian, Spanish, French, and other Mediterranean dishes. Millions of people eat them daily with no ill effects. 

Health Claims About Capers

There are many claims about the benefits of taking large quantities of capers or caper fruit extract as a medicinal agent.

Remember, the effects discussed in these studies are large amounts, much higher than what is eaten in a regular serving of one meal.

One serving of capers is about 1 tablespoon which is equal to about 9-10 grams of whole capers.

The medical studies use caper extract and caper fruit extract, not whole capers. 

However, it is important to note that there is Insufficient Evidence to rate capers’ effectiveness or safety in treating these conditions.

While several studies investigated the benefit of capers, only a couple of small studies limited in scope show any promising results.

Some people claim that using capers as a medicinal product can improve diabetes, fungal infections, chest congestion.

Others claim that caper extracts can cure intestinal worms and leishmaniasis (a parasitical skin disease).


Still, others explain that applying caper extracts can improve skin disorders like dry skin.

It is important to remember that if something sounds too good to be true, it probably is.

The wide variety of claims for this plant should signify that it is too good to be true.

Negative Effects From Capers And Caperberries As Medicinals

There are not any legitimate studies that found capers to be effective at treating any kind of parasite. 

There is also no clear indication that capers have any benefit in clearing lung congestion.

A study conducted in 1991 and another in 2011 determined that rather than healing skin irritation, extract from capers and caperberries caused contact dermatitis and allergic reactions.

One warning you find on multiple websites is that capers have blood-thinning effects and may be dangerous during pregnancy.

This is confusing information. The reason some websites post this warning is that Capers contain rutin, also called rutoside, which is plant pigment.

Rutin is thought to reduce the likelihood of blood clots and strengthen the walls of blood vessels, improving blood flow.

The USDA does not offer any guidelines for using rutin due to the lack of research. Some users have taken this information to indicate that capers may lead to excess bleeding.

However, capers are also high in Vitamin K, which is a known, documented substance that enables clotting according to the USDA, therefore reducing the likelihood of a blood-thinning problem.

This is especially true if you are only eating capers in a meal, and not trying them in a large dose as a medication.

Potential Benefits From Capers And Caperberries As Medicinals

A few studies have shown limited benefits from capers or caperberry extracts. One investigation in 2013 of 60 men found that caper fruit extract in combination with regular treatment and diet change may reduce blood sugar levels in Type 2 diabetics.

The results in this small but promising study have not been repeated. Another study showed that caper fruit extract reduced triglyceride levels in lab rats. 

Collection of Capers

Capers are also rich in antioxidants and have demonstrated health benefits in lab tests, but there hasn’t been a human study.

The conclusion you should take from this research is that capers are safe to eat in a meal whether you are pregnant or not.

What Exactly Are Capers?

We have discussed the benefits and potential drawbacks of capers as a medicinal, but we haven’t covered what capers are and what to do with them. 

Capers are the immature buds of flowers from the prickly caper plant.

It is cultivated in Italy, Morocco, and other Mediterranean regions, and in parts of Asia and Australia.

This small green bud is harvested, dried, then pickled in brine with vinegar, salt, or wine.

The process brings out the flavors of lemon and olive in the capers. If the capers are not harvested, they blossom then grow into caperberries which are just a little larger than capers and are similar to olives but with only a tiny seed.

Nutritional Information For Capers

One serving of capers is about 1 tablespoon, although most recipes call for 3 tablespoons to 1/4 of a cup for 4-6 servings. 1 tablespoon (about 9 grams) of capers has

  • 5 mg potassium (about 1% DV)

What Capers Taste Like 

Capers have a natural lemony-olive flavor. Once they have been dried and pickled, they also develop a sharp, sour taste.

They have a salty taste due to the brine. If you want to reduce the saltiness, you can rinse them before using them in your favorite recipe.

How To Use Capers

Capers are ready to eat right out of the jar. You can toss them in with a salad or finely chop them and use them as a topping on a bagel or a pizza.

Add finely chopped capers to salad dressings, cook them into sauces, or add them to a tapenade.

Small capers can be added whole to roasted or sautéed veggies toward the end of the cooking time.

The flavor of capers works well with salmon, lamb, and pork. They are a frequent ingredient in lemon sauces, remoulades, and Caesar salad dressings. 

Healthy Recipes For Capers During Pregnancy

The following recipes feature foods like salmon and eggplant which support a healthy pregnancy but also include capers so you can experiment with the flavor of this unique ingredient.

Baked Salmon With Capers

While the salmon is cooking, make the caper butter topping.

  1. Melt 3 tablespoons of butter over low heat.
  2. Add one clove of grated garlic and 2 tablespoons of jarred capers, drained. (You can also rinse the capers to reduce the amount of sodium if that is a concern).

Final Thoughts

Capers are a commonly used ingredient in Mediterranean cooking that millions of pregnant women eat every day.

As long as you are eating them in normal amounts used in recipes it is safe to eat capers during pregnancy. 

When you start investigating capers as a medicinal item, you will find many claims about the benefits and dangers associated with them.

Remember that the amounts of caper or caperberry fruit extract in these situations is much higher than a normal amount you would eat in one (or even two) servings of a meal.

Also, there is not enough clear, substantiated scientific information to justify the claims made about capers as a plant medicine.
