What is ultra-processed food, and what are its long-term effects on the human body?

Ultra-processed food is a category of food that has undergone various stages of industrial processing and typically contains a large number of additives, such as preservatives, colorings, flavorings, and emulsifiers. Some common examples of ultra-processed foods include ready-to-eat meals, sweetened beverages, chips, sweet snacks, instant foods, and some processed meat products such as sausages and nuggets.

- Nutritional Content:

Typically low in essential nutrients such as vitamins, minerals, and fiber, but high in sugar, salt, and unhealthy fats.
