A parent’s guide to prebiotics and probiotics – CHOC

By Renae Garcia, dietetic intern at Rady Children’s Health Orange County

Why are prebiotics and probiotics important for kids?

When babies are born, their immune systems are still developing. Breast milk and most infant formulas contain prebiotic fiber. Probiotics can also be found in breast milk and some specialized formulas. When babies start solid foods, the natural prebiotic fibers in them will feed the probiotic bacteria. This supports the growth of a healthy gut microbiome and strong immune system as children grow.

What is the gut microbiome

The gut microbiome is a unique environment mostly found in our large intestines, where close to 100 trillion helpful probiotic bacteria and some yeast (fungi) live and perform important jobs like:

• Helping the body absorb minerals
• Producing vitamins (i.e. b12)
• Fighting off harmful bacteria and viruses 
• Maintaining the right balance of good bacteria
• Breaking down fiber from food we eat
• Creating a healthy intestinal wall
• Supporting healthy and regular bowel movements

What are prebiotics?

Prebiotics are types of fiber found in food the gut can’t break down.  These fibers make their way to the large intestine and act as food for probiotic bacteria.

Good sources of prebiotics fiber

• Fruits:
  • Citrus (oranges, grapefruit, tangerines)
• Vegetables:
  • Brussels sprouts, broccoli, and asparagus
  • Potatoes, sweet potatoes, Jerusalem artichoke (sunchoke)
  • Dark leafy greens like kale, chard, and collards
• Beans and legumes
• Whole grains
• Nuts and seeds
  • Sunflower and pumpkin seeds

What are probiotics?

Probiotics are a group of good bacteria in our gut. They are an important part of our gut microbiome.

Good sources of probiotics

• Yogurt
• Kefir
• Some varieties of cottage cheese
• Sauerkraut
• Kimchi
• Miso
• Tempeh
• Kombucha
• Cultured buttermilk
• Pickled veggies

Should I give my child prebiotic or probiotic supplements?

It’s best for children to get prebiotics and probiotics from foods, not supplements. Both are found in many different foods and are easy to add to the diet. Some children should avoid them, including those with weakened immune systems, short bowel syndrome, or who are in intensive care. Talk with your child’s doctor before use.
