This small-scale study is the first randomly controlled study that is considered a gold standard in research. They are defined as industrial ingredients such as hydrated oils, high fructose corn syrup, flavorings and emulsifiers.
After one month of study, 20 healthy adult volunteers stayed at the National Health Clinics Center, where they received all their meals. In turn, for 14 days they were limited to each diet and told them to eat as much as they liked.
The calorie, sugar, fiber, fat and carbohydrate content of the two meal versions was the same. For example, unprocessed breakfast may be oatmeal with bananas, walnuts and skimmed milk, and the other consists of cream with cream cheese and turkey
Participants used about the same amount each day
People have eaten faster because of a highly processed diet and consumed about 500 calories a day (additional aids) than they did a raw diet; this increase in calories was due to higher carbohydrate and fat content, but not protein. As a result, they gained weight – on average, about 0.9 kg or 2 pounds. When working on unprocessed foods, they lost the same weight.
The sex of the participants, the order of their nutrition, and their body mass index had no effect on the different calories that each participant ate on each diet, according to the authors of the study
. Eating too many calories and gaining weight
Engineering and highly processed foods can be hardly limited due to reasons that are not just taste, stated by scientists. For example, a diet of 2,000 calories per day is estimated to be US $ 106 compared to $ 151 for more natural meals.
More time is also needed to prepare less processed foods.
Fitzgerald recommends that you look back at the prepared food package. "Look at the ingredients list. Do you understand all the ingredients that get into your food?" she asked. Buy only products that contain the least ingredients and ingredients you understand.
The authors of the study argue that consumer confusion is another aspect of this problem.
"Permanent diet wars between fractions promoting low-carb, keto, paleo, high-protein, low-fat, plant, vegan and seemingly endless list of other diets have led to great public confusion and mistrust in nutrition science," they wrote. "Restricting the use of especially processed foods can be an effective strategy for preventing and treating obesity."
