A multidisciplinary expert panel says plain, unsweetened yogurt can be introduced starting at 6 months as part of complementary foods, providing useful nutrients and live microorganisms as well as helping to dispel common myths about dairy in infants.

Recently a special article of the expert panel was published Archivos Argentino de Pediatria Provides a multidisciplinary, evidence-based overview of yogurt in infant nutrition. Based on the insights of a multidisciplinary panel including pediatricians, nutritionists, pediatric gastroenterologists, a psychiatrist and a microbiologist, the review highlights yogurt as a nutrient-rich food rich in protein, vitamins, minerals and live microorganisms, with some products also acting as vehicles for probiotic bacteria that support gut health and immune development. The panel supports introducing yogurt from 6 months of age, as part of a balanced diet, in line with clinical guidance, emphasizing safety, processing and avoiding 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 younger children; Foods like kimchi, miso, and natto may have strong flavors, while other foods like kefir and kombucha may contain small amounts of alcohol. In contrast, yogurt and fresh cheeses are better choices, providing beneficial microbes and important nutrients such as calcium and other micronutrients. Despite these benefits, uncertainty and misconceptions remain regarding the use of yogurt in infant and child nutrition.
In this special article, a multidisciplinary expert panel addressed questions and misconceptions about the use of yogurt in children. Based on clinical practice concerns, the panel selected key questions by consensus. To support their responses, they searched peer-reviewed literature in PubMed, ScienceDirect, and Scopus.
Yogurt: Nutrient Rich Fermented Food in Infant Nutrition
Yogurt is a fermented dairy product traditionally made from pasteurized milk using lactic acid bacteria. Humans have been consuming yogurt for over 4,000 years. With its identification, its benefits were first seen in the Balkan population streptococcus thermophilus And lactobacillus bulgaricuswhich are the primary starter cultures still used today.
Nutritionally, yogurt is a source of live microorganisms, can serve as a vehicle for probiotic bacteria, and provides high-quality protein and essential micronutrients such as calcium, magnesium, phosphorus, zinc, potassium, and vitamins A, B-complex and D. These may help support gut health and immune function. Fermentation enhances the nutritional value of proteins by improving the digestibility of them and increasing the bioavailability of amino acids, calcium, magnesium, phosphorus and some B vitamins, including folate.
Modern production may also include specific probiotic strains, such as l. rhamnosus gg and bifidobacterium animalis Sub. lactisThe standard allows for differentiation between yogurt and probiotic-rich varieties.
Safety and practical recommendations for introducing yogurt in infancy
Health care professionals recommend introducing yogurt around 6 months as part of a balanced complementary feeding pattern, while breast milk or formula continues to provide the main nutritional support. Experts suggest starting with small amounts of yogurt, made from cow’s milk, added to foods such as purees or desserts. They emphasize introducing plain, unsweetened yogurt without added sugar or sweeteners until at least 2 years of age, even though its live microorganisms remain and the probiotic benefits may continue even with minimal sugar content.
Yogurt is generally well tolerated in infants, including those with lactose intolerance, because fermentation reduces the lactose content and improves digestibility. Its composition also slows gastric emptying, allowing better breakdown of lactose. However, there are lactose-free options available if needed. Although yogurt undergoes technical processing such as pasteurization and fermentation, it is not classified as ultra-processed if it is free from additives such as sugar, colors or sweeteners. Furthermore, its nutritional quality remains largely intact depending on the formulation.
Strict heat treatment during production helps to inactivate potentially pathogenic microorganisms, making properly prepared yogurt safe for consumption. However, raw milk yogurt products carry a significantly higher risk of infection, including hemolytic uremic syndrome, and should be avoided in infants. Proper refrigeration is also essential. While yogurt may remain stable for short periods of time due to its acidity, prolonged exposure to room temperature can cause changes in texture and fermentation activity, affecting quality rather than safety.
Debunking Common Myths About Yogurt in Children
Despite widespread misconceptions, scientific evidence does not support the idea that yogurt causes inflammation, excess mucus production, or respiratory symptoms. Studies show that natural, unsweetened yogurt does not increase the risk of tooth decay. Instead, it may support oral health by reducing streptococcus mutansLimiting bacterial adhesion, and inhibiting biofilm formation. Its calcium and phosphorus content may also aid in enamel remineralization when no additional sugars are present.
Similarly, consumption of curd has no relation with 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 unfounded, with any purported effects being due to temporary sensory effects in the mouth rather than actual respiratory changes.
In conclusion, yogurt is a safe, nutrient-rich, evidence-based addition to an infant’s diet from six months of age and may support gut health, immune function and overall nutrition. Its benefits depend on proper use and formulation. While sweetened varieties may also have better nutritional density than confectionery, plain, unsweetened yogurt is the best choice. Better labeling, parental guidance, and further research could help strengthen early life nutrition and its role in long-term health. Danone Argentina SA funded the research, although the authors stated that the company had no editorial control and that the experts participated independently.
