Microbiome Defense Playbook for Children and Families

Goal

Preserve microbial diversity, reduce inflammatory signaling, and promote resilient host–microbe balance.

Pregnancy: Focus on fiber-rich, whole foods. Avoid ultra-processed foods and unnecessary antibiotics.

Birth: Encourage vaginal delivery when safe; prioritize skin-to-skin and early breastfeeding.

Infancy: Breastfeeding preferred; if formula, consider HMO-supported options. Avoid early sugar exposure.

Aim for fiber intake = age + 5 grams/day.

Encourage 20–30 different plant foods per week.

Include resistant starch (beans, oats, cooled rice/potatoes) and fermented foods.

Limit ultra-processed foods, excess sugar, unnecessary antibiotics, and chronic medications affecting gut health.

Reduce exposure to environmental toxins where possible.

Use condition-specific strains when needed (e.g., Lactobacillus rhamnosus GG, Saccharomyces boulardii).

Avoid random or prolonged use without indication. Always discuss with your healthcare provider before using.

Promote good sleep, physical activity, outdoor time, and strong parent-child connection.

Encourage outdoor play, exposure to nature, pets, and social interaction.

Avoid over-sanitization.

Consider CBC, ferritin, RBC zinc/copper, vitamin D, omega-3 index, and inflammatory markers.

Reserve microbiome testing for complex or refractory cases.

Aim for 80–90% whole foods and allow flexibility.

Use team-based care (nutrition, behavioral health).

Support access to healthy foods and track outcomes.

Use team-based care (provider, pharmacist).

Avoidance of antacids and antibiotics when possible
