Six small studies; fortified soy milk may be an adequate alternative for bone.

Does the study support the specific claim? No · Methodological quality: low

Original publication

Plain-language summary

Study explained simply
What did the researchers want to find out?

Check how plant milks affect children's growth.

How was the study done?

Systematic review.

How many people, animals or samples were studied?

6 studies, 15,815 children.

What was actually found?

Lower height, BMI and vitamin D with plant milk; fortified soy may help bone.

How large was the observed effect?

No pooled number.

What do the results mean in everyday life?

If milk is removed, a fortified alternative is needed.

What are the study's limitations?

Observational, few studies.

What does it say about Elawady's specific claim?

Supports the safety note.

Do the results apply to Germany and Europe?

Applicable.

What can explicitly not be concluded from this study?

Cannot prove that plant milk causes shorter height.

Inclusion and exclusion criteria

Studies evaluating growth/nutrition effects of plant-based milk in children

4. Methods and endpoints

Exposure / intervention

Plant-based milk

Comparator

Cow milk

Endpoints

BMI, height, micronutrients, bone density

Statistical methods

Narrative synthesis

5. Actual results

Results

Observational studies: plant-based milk associated with lower childhood BMI, height and serum vitamin D vs cow milk; no association of soy milk with BMI in adolescent girls; low-quality trials showed minimal growth effects; in one study, adolescent girls with low calcium intake who drank fortified soy milk had higher bone density than those who did not.

Absolute risks

not reported

Authors' conclusion

Children who consume plant-based milk may have lower BMI, height and micronutrient intake than those who consume cow milk; fortified soy milk may support bone health in adolescents who do not drink cow milk.

6. Strengths

  • Comprehensive multi-database search
  • Registered protocol

7. Weaknesses

  • Only 6 studies, mostly observational
  • Confounding likely
  • Heterogeneous products (fortification varies)

Rationale

Good search; weak primary evidence.

9. Assessment of the statistical interpretation

Associations only; no pooled estimate.

10. Relevance to the specific claim

Shows that replacing cow milk in children is not neutral unless the substitute is fortified and nutritionally adequate.

11. Independent contrary findings

Fortified soy milk may be an adequate alternative for bone health.

12. Transferability to Germany and Europe

Applies to Egypt; fortified alternatives may be less available (not verified).

13. Overall methodological judgement

Low-certainty but safety-relevant: avoid unplanned removal of milk in children.
