| 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 |
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)
