An update on processed foods: Relationship between salt, saturated and trans fatty acids contents

The highest salt content was found in snacks, fast-food, sauces and ready-to-eat meals, while the saturated fatty acids were higher (p < .05) in bakery products, cookies, biscuits and wafers, and snacks. The highest levels of trans fatty acids were found in the fast-food group, followed by the snacks, potato and potato-products and bakery products. A significant positive correlation (p < .05) was found between salt and fat content in ready-to-eat meals and in the potato and potato-products. The PCA analysis identified total fat, low trans fatty acids and high salt content as distinctive characteristics of some food categories.
