Introduction: Food classified as snacks can be harmful and have adverse health consequences. Sugar, sodium, saturated fats and trans fats are substan- ces whose consumption is recommended to reduce.

Objectives: To quantify the content of sugar, sodium and saturated fats declared in the nutritional labeling of products sold in supermarkets.

Methods: This is a descriptive study where 200 products were selected and classified into four groups: cereal snacks, tuber snacks, dried fruit snacks and non-alcoholic beverages.

Results: After evaluating the content of sugar, sodium and saturated fats declared in the nutritional labeling, the results show that, on average, beve- rages contain 8.9g sugar/100ml, and more than 40% contained more than 10g sugar per 100ml of product. The average sugar content in cereal snacks was 22.06g/100g and the average sodium content was 311.91mg/100g. Likewise, 70% of these products contained more than 10g of sugar per 100g of product. The average content of sugar in fruit and nut snacks was 12.6g sugar/100g and the average sodium content was 250.6mg/100g of product.
The average content of saturated fats in tuber snacks was 10.2g/100g and the average sodium content was 451.00mg/100g; besides, 60% of these products exceed the maximum limits of sodium allowed by the Peruvian standard for critical nutrients (400 mg per 100g of product).

Conclusions:
Non-alcoholic beverages have high content of sugar in one third of them; the amount of sodium is below the limits established for this food group. The cereal snacks provide more sugar than recommended, as well as the saturated fats intake. The dried fruit snacks exceeded the recommendations for sugar content and one third exceeded the permitted levels of sodium content. Regarding tuber snacks, less than 50% of the analyzed products exceed the recommendations for sugar content, suggesting the need for continued public health efforts.
