Table 3 Component loadings for derived dietary patterns by PCA

From: Urinary sodium-to-potassium ratio: a simple and useful indicator of diet quality in population-based studies

Foods groups Dietary patterns
1 (traditional) 2 (Western)
Starched vegetables 0.488  
Non-starched vegetables 0.490  
Salty snacks 0.334  
Sweetened beverages 0.332 0.484
Fruits 0.443  
Nuts and seeds 0.390  
Poultry 0.302  
High-fat dairy 0.321 0.344
Sweet snacks 0.331  
Red meat 0.405  
Beans 0.445  
Refined grains   0.437
Fast foods   0.415
Hydrogenated and animal fat   0.341
Total variance 11.75 9.60
  1. Factors loading < 0.3 are not presented for simplicity. Principal component analysis (PCA) was used to obtain main dietary patterns. The derived dietary patterns explained 21.3% of the total variance in food intake overall (variances of 11.7 and 9.6%, respectively)
