Many people don't know that diet during pregnancy preparation and early pregnancy is not a trivial matter. A prospective study of 855 couples preparing for pregnancy, recently published in Human Reproduction, tells us with real data: the more ultra-processed foods you eat, the more difficult it is to get pregnant and the slower the embryo grows.
Mom eats ultra-processed foods, the real effect on the embryo
The study directly measured the embryo size at 7 weeks of gestation and the results were very clear: For every 5% increase in the energy supply ratio of the mother's ultra-processed food, the length of the top and hip of the embryo decreased by 0.17mm, and the volume of the yolk sac was reduced by 0.01cm³. This is a key developmental indicator recognized in the international field of reproduction. Simply put: the more processed foods you eat, the smaller your baby will grow in the early years. Dad's diet has also been scientifically proven to have an impact: For every 5% increase in the energy supply ratio of ultra-processed food for fathers, the clinical pregnancy rate decreased by 11%, and the time to conception increased by an average of 9%. Men who eat a lot of ultra-processed foods are delayed by 12–18 days. This means: the more unhealthy the father eats, the slower the mother conceives. 1. Sugary drinks, milk tea, energy drinks 2. Cakes, cookies, donuts, chocolates, candies 3. Ham sausage, bacon, sausage, bacon 4. Instant noodles, instant rice, and quick-frozen food 5. Fried chicken, fries, burgers, takeaway fast food 6. Potato chips, puffed snacks, packaged snacks All of these were defined as foods that "affect embryonic development" in the study. "Higher intake of ultra-processed foods before and in the first trimester is significantly associated with smaller embryo size and slower embryo development," the research team clearly wrote. ” In other words: eating too much processed food during pregnancy can really affect the baby's early development. 1. Drink only water, milk, and weak tea 2. Sugary drinks, milk tea, no more than 1 time per week 3. Minimize takeaways, fast food, and snacks The study data shows: The lower the proportion of ultra-processed foods, the better the pregnancy outcome; When husband and wife adjust together, the effect is the most obvious; Mom is responsible for the quality of the embryo and dad is responsible for the speed of conception, both are important. Preparing for pregnancy is not metaphysics It is a eugenic method supported by real data Eat less processed foods It is the best early gift for your baby Content source: Celine H X Lin, Romy Gaillard, Annemarie G M G J Mulders, Vincent W V Jaddoe, Mireille C Schipper, Periconceptional ultra-processed food consumption in women and men, fertility, and early embryonic development, Human Reproduction, 2026, deag023
