More food is induced by over-processed food, which increases the risk of obesity, as a pioneering research suggests that on average 500 calories a day are added.
For the first time, the American study examined the risks of consuming multiple foods with the involvement of volunteers. The participants in the research were watching for one month. It turned out that when the participants consumed heavily processed foods, they took 500 calories a day more than they had eaten unprocessed food, BBC News reported.
The American National Institute for Health estimates that over-processed foods are likely to affect hunger-related hormones, and therefore continue to eat those who consume it.
The exact definition of processed foods is difficult to give, says Kevin Hall, chief researcher of the study, adding that “it’s like pornography, it’s hard to describe, but man immediately recognizes if he sees it”. Includes foods that contain more than five ingredients in their packaging, sweet or flavored salty snacks, chips, chocolate and other sweets, sweetened soft drinks, instant soups, frozen or canned food, and foods mainly or wholly obtained from sugar, oils and fats .
Twenty volunteers were moved to the lab for a month to research.
For two weeks, they either consumed heavily processed foods or unprocessed foods, and then exchanged the second two weeks. The participants ate as much as they wanted, but the researchers recorded every bite they took for themselves.
The processed diet included dishes such as quesadilla and roasted beans, while untreated foods included spinach salad with chicken breast, apple pieces, bulgur and sunflower seeds.
Consumers consuming two weeks of highly processed food consumed an average of 508 additional calories a day and roughly one kilo of it.
Hall, a scientist at the American Institute for Diabetes, Gastrointestinal and Kidney Diseases, stressed that this was the first research to establish a causal relationship between the consumption of over-processed foods and weight gain.
“Processed foods increase calorie intake, increase body weight and gain weight,” Hall said, adding that this relationship may also play a role in obesity in the wider population.
Hall reminded him that the American “obesity epidemic” is caused by the daily consumption of 250-300 extra calories.
The participants in the experiment said that both highly processed and unprocessed foods were “delicious”. So they didn’t eat more of the processed food because they found it better.
The nutrient content of the two types of diets has also been carefully balanced to include sugar and other carbohydrates, fats and fibers in equal proportions.
When one eats unprocessed food, one of the starving hormones, PYY, increases despite having less calories. Research has also shown that the level of the hormone that causes hunger is reduced when consuming unprocessed food.
The study was short-lived with a small group, so it is not clear whether your findings are true for a wider population.
Gunter Kuhnle, a scientist at the University of Reading, said that well-designed and implemented research was interesting, although it was not a surprising result. According to his assessment, the participants found that processed foods were more consumable, eaten faster, and consequently likely to last longer until they reached full sensation.
As pointed out, the other interesting result of the study is the cost per calorie: processed foods were significantly cheaper than the non-processed food dirt, and public health implications are also likely to be significant.
