Ultra-processed Foods Really Do Lead to Weight Gain
Updated: Nov 18, 2019
Filling your plate with ultraprocessed foods really does appear to lead people to eat more and gain weight, according to a new study.
According to Elate Nutrition Experts, ultraprocessed foods alludes to items that will in general experience a number of manufacturing steps to be produced, and contain fixings that outcome from industrial nourishment producing, for example, hydrogenated oils, high-fructose corn syrup, seasoning specialists and emulsifiers, as indicated by studies.
For example, an ultraprocessed breakfast meal could consist of a bagel with cream cheese and turkey bacon, while an unprocessed breakfast could contain oatmeal with bananas, walnuts and skim milk.
The study, published May 16 in the journal cell metabolism involved 20 healthy volunteers who spent about a month in a laboratory at the National Institutes of Health's (NIH) Clinical Center in Bethesda, Maryland, where all of their meals were prepared for them. Participants were randomly assigned to a diet of either ultraprocessed or minimally processed foods for two weeks, after which they were switched to the opposite diet for another two weeks. Importantly, meals for both groups had about the same amount of calories, sugars, fiber, fat and carbohydrates participants could eat as much as they wanted.
The researchers found that, when people were given the ultraprocessed diet, they ate about 500 calories more per day than they did when they were on the unprocessed diet. What's more, participants gained about 2 pounds (0.9 kilograms) while they were on the ultraprocessed diet; they lost about 2 pounds while on the unprocessed diet.
Previous studies that involved large groups of people have linked diets high in ultraprocessed foods with health problems, and even a higher risk of early death. But these studies observed people over time, rather than assigning them specific diets, and so could not prove that ultraprocessed foods actually cause people to eat more or gain weight. For example, it might be the case that people who eat ultraprocessed foods develop health problems for other reasons, such as a lack of access to fresh foods.
Although the new study was small, "results from this tightly controlled experiment showed a clear and consistent difference between the two diets," study lead author Kevin Hall, a senior investigator at NIH's National Institute of Diabetes and Digestive and Kidney Diseases, said in a statement. "This is the first study to demonstrate causality — that ultraprocessed foods cause people to eat too many calories and gain weight."
"Limiting consumption of ultraprocessed food may be an effective strategy for obesity prevention and treatment," the researchers concluded.
All things considered, the study found that individuals would in general eat their meals quicker when they were on the ultraprocessed diet compared with the unprocessed diet. Some past studies have proposed that quicker eating rates can result in increased overall food intake, the researchers said The scientists noticed that ultraprocessed food will in general be gentler and simpler to swallow, which may have prompted the quicker eating rate and delayed feelings of fullness, which could have contributed to increased food intake.
The researchers noted that ultraprocessed foods can be difficult to cut back on, given their convenience and low cost. We have to be mindful that it takes more time and more money to prepare less-processed foods. Contact Elate nutrition experts for the overall management of food habits.
