A new study reveals that diets rich in minimally-processed foods offer more significant benefits for weight loss than those relying on ultra-processed foods. Experts say that the key difference lies in how much processing has altered the food’s nutritional content and palatability.
According to Dr. Amar Dave, a lifestyle medicine specialist, processed foods are those that have been changed in some capacity, such as heating, freezing, or dehydrating. However, not all processed foods are created equal. Ultra-processed foods, on the other hand, undergo significant processing to enhance their taste and shelf life, often at the expense of nutritional value.
The NOVA classification system is a framework used by researchers to categorize foods into four categories: unprocessed or minimally processed foods, processed culinary ingredients, processed foods, and ultra-processed foods. Under this system, minimally-processed foods are those that have undergone minimal changes, such as removing inedible parts or freezing, while ultra-processed foods undergo extensive processing, often involving industrial methods and additives.
Diets rich in ultra-processed foods tend to be high in salt, fat, and added sugar, making them more palatable but also increasing the risk of chronic diseases like diabetes, cancers, and heart disease. Experts recommend prioritizing whole and minimally-processed foods, such as fruits, vegetables, whole grains, lean proteins, and essential vitamins and minerals.
While an occasional ultra-processed food is unlikely to cause harm, a diet dominated by these foods can have negative consequences on overall health. The key takeaway is that understanding the difference between minimally-processed and ultra-processed foods is crucial in making informed dietary choices.
