Biochemist Jessie Inchauspé Debunks 3 Dangerous Pregnancy Myths

Maternal nutrition is often oversimplified, yet it acts as the primary architect of a developing child’s future. Jessie Inchauspé, the renowned French biochemist and “Glucose Goddess,” is urging expectant mothers to look past the scales and focus on “DNA programming.”

In a recent viral update, Inchauspé explains that what a mother consumes serves as a “biological postcard” to the fetus, signaling what the outside world is like and shaping the child’s lifelong metabolism and disease risk.

Myth 1: “The baby will always get what it needs from my body.”

Many believe that the fetus acts as a perfect parasite, extracting necessary nutrients regardless of the mother’s diet. Inchauspé warns this is a dangerous misconception.

The Reality: Certain critical building blocks, specifically Choline and DHA (an omega-3 fatty acid), must be consumed intentionally.
The Gap: Studies show that nearly 90% of pregnant women are deficient in choline, and 70% do not get enough DHA. Without these, fetal brain development may not reach its full potential.

Myth 2: “The placenta filters out all the ‘bad stuff’ from the baby.”

People often view the placenta as a sophisticated fortress that shields the baby from toxins or poor nutritional choices.

The Reality: Inchauspé compares the placenta to a “lax bouncer” rather than a fortress. It largely follows the rule of concentration: if a substance is high in the mother’s bloodstream, the placenta assumes it should also be in the baby’s.
The Takeaway: Everything you eat, the baby effectively “eats” too. High glucose spikes or inflammatory ingredients in the mother’s blood are mirrored in the developing child.

Myth 3: “Weight gain is inevitable, so I can eat whatever I want.”

The “eating for two” hall pass often leads to a diet high in processed sugars and refined carvings under the guise of “pregnancy cravings.”

The Reality: This is the most critical myth regarding epigenetics. High sugar intake during pregnancy can “program” the baby’s DNA to have a higher baseline risk for Type 2 diabetes and metabolic disorders before they are even born.
The Message: A healthy diet provides the “information” the baby’s body uses to form itself correctly. Poor nutrition sends signals that can lead to permanent, detrimental biological consequences.

The Glucose Goddess’s Advice for Expectant Moms

To manage blood sugar and provide the best “DNA programming,” Inchauspé recommends her signature hacks, such as:

Savory Breakfasts: To avoid early morning glucose spikes.
Fiber First: Eating vegetables at the start of a meal to slow down sugar absorption.
“Clothe Your Carbs”: Never eating carbohydrates on their own; always pair them with protein, fats, or fiber.
