Experts exclude canned legumes and canned fish from ultra-processed foods. Canned foods should not be confused with ultra-processed foods. Canned legumes, frozen vegetables, or canned fish are examples of healthy processed foods that maintain their nutritional properties and are part of a balanced diet, according to food technology specialists.

In contrast, regular consumption of ultra-processed foods—such as cookies, pizzas, pastries, soft drinks, sausages, nuggets, pre-cooked meals, or dairy desserts—has been linked to a significant increase in pathologies. A study presented at the latest congress of the American Society of Cardiology revealed that adding 100 grams daily of these products increases the risk of hypertension by 14.5%, cardiovascular events by 5.9%, cancer by 1.2%, digestive diseases by 19.5%, and mortality from any cause by 2.6%.

The general guideline from experts is to base your diet on fresh or simply processed foods, such as fruit, fish, or canned legumes, leaving ultra-processed foods for occasional consumption.
