Newborns may have low birth weight and face an increased risk of developing conditions such as obesity, diabetes, and cardiovascular diseases\u2014including heart attacks\u2014later in life.<\/p>\n\n\n\n<p>This phenomenon is known as <strong>fetal programming<\/strong>, a process in which conditions during pregnancy\u2014such as poor nutrition\u2014can send the fetus <strong>\u201cfaulty instructions\u201d<\/strong> <strong>even before birth,<\/strong> explained <a href=\"https:\/\/www.researchgate.net\/profile\/Rosa-Maria-Gueant-Rodriguez\" target=\"_blank\" rel=\"noreferrer noopener\">Rosa Mar\u00eda Gu\u00e9ant<\/a>, a professor and expert in metabolic biochemistry and nutrition at the University of Lorraine and the University Hospital of Nancy. She spoke during the <a href=\"\/en\/tag\/international-conference-on-obesity-research-2025\/\" target=\"_blank\" rel=\"noreferrer noopener\">International Congress on Obesity Research 2025.<\/a><\/p>\n\n\n\n<p>During her talk,<em><strong> B Vitamins, the Epigenome, and Fetal Programming<\/strong><\/em>, Gu\u00e9ant explained that if a pregnant woman does not get adequate nutrition, <strong>the baby&#8217;s body may be \u201cprogrammed\u201d to store fat,<\/strong> function with fewer nutrients, or struggle to process sugar\u2014essentially<strong> adapting to a nutrient-poor environment<\/strong>. However, these early-life adaptations can increase the risk of developing metabolic diseases and organ issues in adulthood, particularly in the liver and heart.<\/p>\n\n\n\n<p>Vitamin B12, found in foods like meat and fish, and folates\u2014such as vitamin B9, which comes from vegetables\u2014help regulate fetal genes during pregnancy through a process called methylation. This mechanism acts like a control system that determines which genes are switched on or off during development.<\/p>\n\n\n\n<p>In her <a href=\"https:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S0083672922000164\" target=\"_blank\" rel=\"noreferrer noopener\">research<\/a>, Gu\u00e9ant has shown that disruptions in this regulatory process can result in low birth weight due to altered genetic instructions.<\/p>\n\n\n\n<p>\u201cThe required amount of B12 is extremely small\u2014just four micrograms a day. And that\u2019s enough,\u201d said Gu\u00e9ant.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe title=\"Cient\u00edficos detectaron micropl\u00e1sticos en la leche materna\" width=\"800\" height=\"450\" src=\"https:\/\/www.youtube.com\/embed\/ATMQ557pA24?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><figcaption class=\"wp-element-caption\">Captions are available in English.<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">B12\u2019s Role in Babies<\/h2>\n\n\n\n<p>When pregnant women are deficient in vitamins like B12 and folates (folic acid), their babies don\u2019t receive enough <strong>methyl groups<\/strong>\u2014one of the key <strong>epigenetic mechanisms<\/strong> involved in development. Epigenetics refers to the way a fetus\u2019s genes are regulated during gestation, depending in large part on maternal nutrition.<\/p>\n\n\n\n<p>Gu\u00e9ant pointed out that there are <strong>three main epigenetic mechanisms that regulate gene behavior<\/strong>: DNA methylation, which adds methyl groups to suppress certain genes; histone modification, which alters the proteins surrounding DNA and affects gene accessibility; and non-coding <a href=\"\/en\/biotechnology\/what-is-rna\/\" target=\"_blank\" rel=\"noreferrer noopener\">RNAs<\/a>, which regulate gene activity without turning into proteins themselves.<\/p>\n\n\n\n<p>In other words,<strong> when these genetic instructions are altered, fetal development can be affected.<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full\"><picture>\r\n                <source srcset=\"https:\/\/tecscience.tec.mx\/en\/wp-content\/uploads\/sites\/9\/2025\/04\/what-is-rna-2-1024x1024-1.webp\" type=\"image\/webp\">\r\n                <img fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"1024\" src=\"https:\/\/tecscience.tec.mx\/en\/wp-content\/uploads\/sites\/9\/2025\/04\/what-is-rna-2-1024x1024-1.jpg\" alt=\"\" class=\"wp-image-169449\" srcset=\"https:\/\/tecscience.tec.mx\/en\/wp-content\/uploads\/sites\/9\/2025\/04\/what-is-rna-2-1024x1024-1.jpg 1024w, https:\/\/tecscience.tec.mx\/en\/wp-content\/uploads\/sites\/9\/2025\/04\/what-is-rna-2-1024x1024-1-300x300.jpg 300w, https:\/\/tecscience.tec.mx\/en\/wp-content\/uploads\/sites\/9\/2025\/04\/what-is-rna-2-1024x1024-1-150x150.jpg 150w, https:\/\/tecscience.tec.mx\/en\/wp-content\/uploads\/sites\/9\/2025\/04\/what-is-rna-2-1024x1024-1-768x768.jpg 768w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/>\r\n            <\/picture><\/figure>\n\n\n\n<p>\u201cWhen a gene is methylated, its protein expression decreases. A lack of methyl group donors contributes to fetal programming\u2014especially in the liver and heart. The result is inflammation, fibrosis, and steatosis (fat accumulation),\u201d Gu\u00e9ant explained.<\/p>\n\n\n\n<p>She presented findings from various studies examining how maternal vitamin deficiencies impact fetal programming and babies\u2019 metabolic development. In one study using a rat model, <strong>female rats were fed a deficient diet during mating, pregnancy, and lactation<\/strong>. Researchers then analyzed how this lack of nutrition affected their offspring.<\/p>\n\n\n\n<p>The pups were born with low body weight, but by day 21 had already accumulated abdominal fat and developed liver steatosis, mitochondrial abnormalities in the heart, and reduced metabolic functions.<\/p>\n\n\n\n<p>In a separate population-based study in France, Gu\u00e9ant analyzed 682 samples of placentas, umbilical cords, and blood from children under age five. The goal was to trace how maternal nutrition and fetal metabolism shape biological markers from birth through early childhood. The results identified methylated genes linked to body fat percentage at age five, as well as metabolites associated with insulin resistance.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full\"><picture>\r\n                <source srcset=\"https:\/\/tecscience.tec.mx\/en\/wp-content\/uploads\/sites\/9\/2025\/04\/1-6.webp\" type=\"image\/webp\">\r\n                <img decoding=\"async\" width=\"750\" height=\"500\" src=\"https:\/\/tecscience.tec.mx\/en\/wp-content\/uploads\/sites\/9\/2025\/04\/1-6.jpg\" alt=\"\" class=\"wp-image-169450\" srcset=\"https:\/\/tecscience.tec.mx\/en\/wp-content\/uploads\/sites\/9\/2025\/04\/1-6.jpg 750w, https:\/\/tecscience.tec.mx\/en\/wp-content\/uploads\/sites\/9\/2025\/04\/1-6-300x200.jpg 300w\" sizes=\"(max-width: 750px) 100vw, 750px\" \/>\r\n            <\/picture><figcaption class=\"wp-element-caption\">Roc\u00edo D\u00edaz, head of the Integrative Biology Unit at IOR, and Rosa Mar\u00eda Gu\u00e9ant at the Conference organized by IOR.
