Higher nutrition knowledge is weakly linked to better dietary intake, especially fruit and vegetable consumption, in adults. More high-quality research is needed to confirm this relationship and inform public health policy.
Area of Science:
- Nutrition Science
- Public Health
Background:
- Nutrition knowledge is a key component of health literacy.
- Low health literacy is linked to adverse health outcomes.
- Understanding the link between nutrition knowledge and dietary intake is crucial for public health.
Purpose of the Study:
- To systematically review the association between nutrition knowledge and dietary intake in adults.
- To identify the strength and direction of this relationship.
- To highlight gaps in current research.
Main Methods:
- Systematic review of original research articles published until November 2012.
- Inclusion criteria: quantitative assessment of both nutrition knowledge and dietary intake with statistical association.
- Searched multiple databases using terms related to nutrition knowledge and dietary intake.
Main Results:
- Twenty-nine studies were included, mostly in community (n=22) versus athletic (n=7) populations.
- A meta-analysis was not possible due to methodological heterogeneity.
- 65.5% of studies found a significant, positive, but weak association (r<0.5) between higher nutrition knowledge and better dietary intake, particularly fruit and vegetable consumption.
Conclusions:
- A weak positive association exists between nutrition knowledge and dietary intake.
- Study quality varied, with limited representation from lower socio-economic status groups.
- Further well-designed studies using validated methods are essential to clarify this relationship and inform nutrition education and policy.
