A multidisciplinary panel of experts says plain, unsweetened yogurt can be introduced from six months of age as part of a complementary diet, providing useful nutrients and live microorganisms, while helping to debunk common myths about dairy products in infants.
Review: Yogurt in infant nutrition: answers to frequently asked questions. Image credit: Dombrovschi Natalia / Shutterstock
A recent expert panel special article published in Archivos Argentinos de Pediatría provides a multidisciplinary, evidence-based overview of yogurt in infant nutrition. Based on insights from a multidisciplinary panel including pediatricians, nutritionists, pediatric gastroenterologists, psychiatrists, and microbiologists, this review highlights that yogurt is a nutritious food rich in protein, vitamins, minerals, and live microorganisms, and some products also act as vectors for probiotic bacteria that support gut health and immune development. The panel supports the introduction of yoghurt from six months of age, in line with clinical guidance, as part of a balanced diet, with a focus on safety, processing and avoidance of added sugars.
Fermented foods are widely recommended in pediatric nutrition guidance to increase dietary diversity and support gut and immune health. However, some are less suitable for young children. Foods such as kimchi, miso, and natto may have strong flavors, while foods such as kefir and kombucha may contain small amounts of alcohol. In contrast, yogurt and fresh cheese, which provide beneficial microorganisms and important nutrients such as calcium and other micronutrients, are better options. Despite these benefits, uncertainty and misconceptions persist regarding the use of yogurt in infant and child nutrition.
In this special article, a multidisciplinary panel of experts addressed questions and misconceptions regarding yogurt use in children. Based on concerns from clinical practice, the committee selected key questions based on consensus. To support their answer, they searched peer-reviewed literature in PubMed, ScienceDirect, and Scopus.
Yogurt: a nutritious fermented food in infant nutrition
Yogurt is a fermented milk product traditionally made from pasteurized milk using lactic acid bacteria. Humans have been consuming yogurt for over 4,000 years. Its benefits were first noticed in the Balkan peoples, and at the same time thermophilus and bulgarian lactic acid bacteriais the starter culture still primarily used today.
Nutritionally, yogurt is a source of live microorganisms, acts as a vehicle for probiotic bacteria, and provides high-quality protein and essential micronutrients such as calcium, magnesium, phosphorus, zinc, potassium, vitamins A, B complex, and D. These may help support gut health and immune function. Fermentation further increases nutritional value by improving the digestibility of proteins and increasing the bioavailability of certain B vitamins, including amino acids, calcium, magnesium, phosphorus, and folic acid.
Modern production may also incorporate certain probiotic strains, such as: L. rhamnosus GG and Bifidobacterium animalis subspecies of milkit is possible to differentiate between standard yogurt and probiotic-enriched varieties.
Safety and practical recommendations when introducing yogurt in infancy
Medical experts recommend introducing yogurt around 6 months of age as part of a balanced complementary feeding pattern, while breast milk or formula continues to provide the primary nutritional support. Experts suggest starting with a small amount of yogurt made from milk and mixed into foods like purees and desserts. They emphasize serving plain, unsweetened yogurt with no added sugar or sweeteners until at least 2 years of age, even though even minimal sugar content may retain live microorganisms and probiotic benefits may last.
Yogurt is generally well tolerated by infants, including those with lactose intolerance, because fermentation reduces lactose content and improves digestibility. Its texture also slows gastric emptying and promotes the breakdown of lactose. However, lactose-free options are available if desired. Although yogurt undergoes technical processing such as pasteurization and fermentation, it is not classified as ultra-processed if it does not contain additives such as sugar, coloring, or sweeteners. Moreover, depending on the formulation, its nutritional quality remains largely intact.
Rigorous heat treatment during manufacturing ensures that potentially pathogenic microorganisms are inactivated, making properly prepared yogurt safe for consumption. However, raw milk yogurt products should be avoided in infants because they carry a very high risk of infections such as hemolytic uremic syndrome. Proper cooling is also essential. Because yogurt is acidic, it can remain stable for short periods of time, but prolonged exposure to room temperature can change the texture and fermentation activity, affecting quality rather than safety.
Debunking common misconceptions about children’s yogurt
Despite being widely misunderstood, the idea that yogurt causes inflammation, excess mucus production, or respiratory symptoms is not supported by scientific evidence. Research shows that natural, unsweetened yogurt does not increase the risk of cavities. Instead, it may support oral health by reducing it. Streptococcus mutanslimit bacterial adhesion and interfere with biofilm formation. If no sugar is added, its calcium and phosphorus content may also help remineralize enamel.
Similarly, no link has been found between yogurt consumption and acne. In fact, fermented dairy products may provide protective effects through anti-inflammatory compounds such as lactic acid and bioactive peptides. Concerns that dairy products increase mucus or worsen asthma are also unsupported, and the perceived effects are likely due to temporary sensory effects in the mouth rather than actual changes in breathing.
In conclusion, yogurt is safe, nutritious, and science-based addition to infants’ diets starting at 6 months of age and may support gut health, immune function, and overall nutrition. Its benefits depend on proper usage and formulation. Although sweetened varieties may be more nutritious than sweets, unsweetened plain yogurt is still the best choice. Improved labeling, parent guidance, and further research may help strengthen early childhood nutrition and its role in long-term health. Danone Argentina SA funded the study, but the authors said the company had no editorial control and the experts participated independently.
