Probiotics play a crucial role in supporting healthy gut microbiome . The condition of our kid’s microbiome can impact digestion, gut motility, and constipation . Probiotics use prebiotics, like Begin Health’s Growing Up Prebiotics as fuel to create a flourishing and diverse microbiome. Just like how our kids’ bodies need the right nutrition to stay healthy, prebiotics are the nutrition probiotics need to set the foundation for a healthy gut. Incorporating a variety of probiotic-rich foods into your kiddos’ diet can help promote regular bowel movements . Let’s explore some of the top sources of naturally probiotic-rich foods for kids, how much probiotics they provide, and review how they can help digestive health and provide additional constipation support for our kiddos.
How much probiotics are found in foods?
Probiotics identified by different strains of good bacteria. Some of the most common strains identified in probiotic products are :
Probiotics strains are measured by the Colony Forming Units (CFUs) which indicate the total number of cells that are alive and working. It’s important to note that a higher CFU number does not indicate that a health product has better health effects. Instead, review the quality of the bacteria strain by looking for well-researched strains. The two most researched strains of probiotics in kids include Lactobacillus and Bifidobacterium . The recommended dosage will vary depending on your child’s age and health needs, but most studies show that doses ranging from 10 million to 10 billion CFUs may be beneficial to their health .
Yogurt (with live and active cultures)
Yogurt, specifically ones that indicate “live and active cultures” on the label will contain probiotics such as Lactobacillus and Bifidobacterium, which both support gut health in kids . Bifidobacterium breve specifically has shown to be effective for increasing stool frequency in kids with functional constipation . Opt for plain yogurt and add fresh fruits or a drizzle of pure maple syrup for natural sweetness.
For an extra boost, try mixing in our Growing Up Prebiotic into your kiddos favorite yogurt. Our prebiotic blend contains chicory root fiber, which can support softer stools and increase stooling frequency with daily consistent use . Prebiotics feed beneficial gut bacteria in our digestive system to promote good gut health .
Kefir is a fermented dairy product similar to yogurt but with a thinner consistency. It is rich in probiotics, including Lactobacillus and Bifidobacterium strains, which can improve friendly gut bacteria and provide constipation support for kids . The fermented components in kefir also show additional health promoting characteristics linked to improving the microbiome and immunity . For a nutritious probiotic boost, drink it on its own, mix into oatmeal or use it as a base for smoothies.
Sauerkraut is made from fermented cabbage and contains lactobacillus bacteria that aid in digestion and promote regular bowel movements . Introduce small amounts of sauerkraut to your little one’s meals gradually to let their taste buds adjust to the tangy flavor. Incorporating sauerkraut in sandwiches or as a side dish can be an enjoyable way to include probiotics in their diet.
Kombucha is a fermented tea beverage that contains various strains of beneficial bacteria and yeast, such as Saccharomyces cerevisiae. Studies on Saccharomyces cerevisiae indicate that it is effective against different gastrointestinal diseases and contain anti-inflammatory properties .
It is important to note that kombucha does contain a small amount of natural alcohol due to the fermentation process, typically around 0.5% or less per serving. The industry standards in the United States require that store-bought kombucha must maintain less than 0.5% alcohol by volume, ABV, to be classified as a non-alcoholic beverage . The percent ABV is comparable to the natural alcohol content found in yeast breads . A standard serving is generally safe for kids ages 4 and above. Start with small amounts and monitor your kid’s reaction to ensure they tolerate it well. Opting for low-sugar options can help avoid excessive added sugar intake. The American Heart Association recommends no more than 25 grams of added sugars (6 tsp) per day for kids two years of age or older.
Kids’ Added Sugar Recommendations
Not recommended for this age group
2 years and up
Foods like pickles, tofu, and certain cheeses like feta  are all made through the process of fermentation, which uses bacteria or yeast to break down the food to naturally produce probiotics. Offering a variety of fermented foods to your kiddos can help them expand their palate and promote a healthy digestive system.
