Why Am I Craving Olives During Pregnancy?

Health Benefits Of Olives During Pregnancy
If you’re craving olives, you’re in luck. These little fruits offer several health benefits. Let’s take a look at how olives can support your body during pregnancy.
Rich in Healthy Fats
Olives are a great source of fat. Fat is a type of macronutrient that helps promote hormone health and body temperature regulation. Fats also help you stay full longer and make meals more satisfying.
Olives are rich in a type of healthy fat known as monounsaturated fat (3). Monounsaturated fats are plant-based nutrients that can help improve heart health.
The fat found in olives can help lower your LDL (“bad”) cholesterol, which may reduce your risk of heart disease and stroke (4).
Olives are a great source of antioxidants, which can help protect against oxidative stress and DNA damage from everyday stressors on our bodies. Antioxidants also help fight against inflammation.
The specific antioxidants found in olives are: (5)
- Beta carotene
- Vitamin E
Helps with Electrolyte Balance
Olives are high in sodium, which is a mineral and an electrolyte that helps with muscle contractions, nerve function, and fluid balance (6).
Most Americans get plenty of sodium from food. In fact, sodium gets a bad rap because excessive sodium intake has been associated with high blood pressure.
Unfortunately, nausea and vomiting are common during pregnancy. When you vomit, you are losing fluids and electrolytes.
Drinking plain water can help replace the fluid loss, but sometimes adding extra minerals, such as sodium, can help replace what was lost when you were sick.
If you are regularly vomiting, olives may be a great addition to your diet to replace some of this lost sodium.
While they offer several benefits, there are also a few things you need to know to make sure that eating olives in pregnancy with a safe option for you.
Potential Risks of Olives During Pregnancy
High in Sodium
One potential consideration before cracking open that can of olives is the sodium content.
Olives are high in sodium. While this can be helpful for people experiencing frequent nausea and vomiting, high intakes of sodium may also increase fluid retention.
Holding onto extra fluid can be uncomfortable for many women, and for some, the increased sodium may increase their risk of high blood pressure (7).
Risk for Foodborne Illness
Olives that have not been stored at the proper temperature can increase your risk of illness, which can be especially dangerous during pregnancy. However, there are some ways that you can reduce your risk of getting sick from olives:
- Use it prior to the expiration date.
- When you purchase olives, have them back in the refrigerator within 2 hours of opening.
