Eating for Two: Nutrition Myths Busted: Debunking common pregnancy nutrition myths.

The journey of pregnancy is one filled with excitement, anticipation, and a fair share of myths, especially when it comes to nutrition. The adage “eating for two” has long guided the dietary habits of expectant mothers, but not all the advice that comes with it is backed by science. With a goal to unravel the tangled web of pregnancy nutrition folklore, this blog aims to debunk common pregnancy nutrition myths and provide evidence-based guidelines to support both maternal and fetal health. Let's differentiate fact from fiction and ensure a well-nourished journey towards childbirth.

Article Outline

Myth 1: Eating for Two Means Eating Twice as Much

The notion that expectant mothers need to double their food intake is one of the most pervasive pregnancy nutrition myths. In reality, caloric needs only increase modestly during pregnancy. The Institute of Medicine suggests an additional:

  • No extra calories in the first trimester.
  • About 340 extra calories per day in the second trimester.
  • About 450 extra calories per day in the third trimester.
It’s more important to focus on the quality rather than the quantity of food consumed, emphasizing nutrients that support fetal development, like folate, iron, calcium, and omega-3 fatty acids.

Myth 2: Cravings Indicate Nutritional Deficiencies

While a craving for chocolate or citrus might seem like the body’s way of signaling a deficiency, there is little scientific evidence to back this up. Cravings during pregnancy are common and believed to be caused by hormonal changes, rather than an indication of the body’s nutrient needs. It is okay to indulge in cravings occasionally, but it's crucial to maintain a balanced diet for overall health.

Myth 3: Avoid Seafood Altogether for a Safe Pregnancy

Another common myth involves the exclusion of seafood from a pregnant woman's diet due to concerns over mercury exposure. However, not all seafood is high in mercury, and many types are rich in essential nutrients like omega-3 fatty acids that are important for brain development. The Food and Drug Administration (FDA) recommends consuming 8-12 ounces of low-mercury fish per week, such as salmon, sardines, or tilapia.

Myth 4: A Vegetarian Diet Lacks Sufficient Nutrients for Pregnancy

A well-planned vegetarian diet can support a healthy pregnancy, but careful planning is needed to ensure it includes adequate protein, iron, vitamin B12, and omega-3s, which can be more challenging to obtain from plant-based sources. Pregnant vegetarians might consider fortified foods or supplements specifically designed to meet these needs.

Myth 5: Pregnant Women Should Completely Abstain from Caffeine

It's a common belief that caffeine is a no-go for expectant mothers, but moderate intake is generally considered safe. The American College of Obstetricians and Gynecologists (ACOG) states that pregnant women can safely consume up to 200 milligrams of caffeine per day, equivalent to one 12-ounce cup of coffee. However, it's important to consider that caffeine is found in many other products such as teas, sodas, and chocolate.

Myth 6: All Cheeses are Off-Limits During Pregnancy

Fear surrounding the consumption of cheese during pregnancy stems from the risk of listeria, a type of bacteria that can be harmful to the fetus. Nevertheless, not all cheeses pose this risk. Hard cheeses, along with pasteurized soft cheeses, are considered safe. Pregnant women should avoid unpasteurized soft cheeses, such as brie, feta, and blue cheese, unless they are clearly labeled as made with pasteurized milk.


Dispelling myths surrounding pregnancy nutrition not only lightens the load of expectant mothers but also paves the way for informed decisions that promote optimal health outcomes. By debunking prevalent misunderstandings and focusing on evidence-based dietary practices, we contribute to the well-being of both mothers and their babies. Remember, a balanced, nutrient-dense diet that fits individual health profiles and needs is key, consulting healthcare professionals when in doubt ensures a safe and nutritious dietary journey throughout pregnancy.
