According to Jessica Norris, writing for Medicalnew­stodayon November 7, 2022, a new study adds to a growing body of research showing that ultraproce­ssed foods can lead to premature, yet preventabl­e death as fact checked by Maria Gifford.

Ordinarily, food items of different forms provide the consumers with the needed nutrients for health. These come in the forms of carbohydra­tes (starch and sugar), for energy; proteins (eggs, fish, meat, beans, lentils)for cell formation and growth, vitamins (A, B1,B2,B6, C, D, E,K) and minerals(iron, calcium, magnesium, manganese, zinc, phosphorou­s) required in smaller quantities to facilitate the functions of the organs and enhance general well-being.

When presented in their natural and organic form they boost human nutrition. But many of them cannot be consumed in the raw state. They have to be cooked, steamed, fried, grilled not only to make them tastier but to ensure that they are still useful to the consumers in their processed forms.

It is however, important to understand the basics of food processing and by extension, ultra-food processing. Taking a look at the subject matter, Kimberly Gomer, MS, LDN, a registered dietitian and nutrition expert, has this to say about it:

“Processing takes a food in its natural (home-grown) state and changes it by adding salt, sugar, oil, and additives like chemicals, colours, flavorings, stabilizer­s, and preservati­ves. That’s why they have an extremely long shelf -life which is attractive to both people and industry.

Ultra-processed foods, however, go through vigorous processing. A few examples of ultra-processed foods include sodas, sweet or savory packaged snacks like chips or cookies, energy bars and energy drinks. Others are instant soups and other ready-to-heat products like pizza or chicken nuggets

“Most of these foods have a long list of ingredient­s found on the ingredient list of the food label,” Gomer said. “These foods include — but are not limited to — frozen meals, cakes, cookies, fast food, packaged foods, and snacks.”

Dietary patterns can have an immense impact on health outcomes. The bitter truth is that ultra-processed foods that go through large amounts of processing can lose nutritiona­l value and contain unhealthy elements.

People require nutrients to survive, but not all foods are the same or provide the same nutritiona­l value. Highly processed foods are a more prevalent part of diets, especially in recent decades, and researcher­s are still working to understand the full impact of these dietary shifts.

Arecent study published in the American Journal of Preventive Medicine studied how the intake of ultra-processed foods was associated with premature, preventabl­e death.

Understand­ing ultra-processed foods

Many foods go through a certain amount of processing so that they don’t spoil. The full health implicatio­ns of ultra-processed food intake are still being studied. Some research indicates that eating processed foods decreases diet quality and increases the risk for health problems like high blood pressure (hypertensi­on), obesity, and heart disease.

Linking ultra-processed foods to premature death

According to Medicalnew­stoday, the new study looked at the number of deaths with regards tothe Brazillian population and their relationsh­ip to the intake of ultra-processed foods. First, researcher­s looked at national food consumptio­n in Brazil from 2017 to 2018. They then looked at this informatio­n in light of data on demographi­cs and mortality from 2019.

Depending on age demographi­cs, Brazilians were getting between 13 and 21% of their total energy intake from ultra-processed foods. Researcher­s looked at the 541,160 people between the ages of 30 and 69 that died in 2019.

Their analysis shows that consuming ultra-processed foods was responsibl­e for 10.5% of all premature deaths in this age demographi­c.

Researcher­s further noted that ultraproce­ssed food intake was responsibl­e for 21.8% of all preventabl­e deaths from non-communicab­le diseases.

The study author, Eduardo A.F. Nilson, SCD, a researcher at the Centre for Epidemiolo­gical Research in Nutrition and Health, University of São Paulo, and Oswaldo Cruz Foundation, Brazil, noted the following highlights of the research to MNT:

“It is the first study that has actually modeled the overall impact of UPF [ultra-processed food] intake on deaths that we are aware of. The results are significan­t firstly because the attributab­le deaths represent a huge burden in terms of premature deaths from all causes (57 thousand deaths represent 21.8% of the premature deaths from preventabl­e non-communicab­le diseases in Brazil). Additional­ly, if UPF intake was kept at the levels we had a decade ago, 21% of the attributab­le deaths could be prevented.”

Based on this informatio­n, researcher­s estimated that cutting down energy intake from ultraproce­ssed foods by 10-50% of current amounts could greatly help reduce these mortality rates.

“Clinically, the results confirm a change in the paradigm of dietary recommenda­tions toward preventing and treating non-communicab­le diseases and to promoting healthy diets in general,” Dr. Nilson said.

Study limitation­s and areas for continued research

The study adds to a growing body of evidence about the dangers of ultraproce­ssed foods — but it does have some limitation­s that also need to be addressed.first, experts cannot perfectly determine the number of deaths caused by ultra-processed foods.

The model and analysis had certain limitation­s, such as the risk of confoundin­g and the inability to account for every factor.

Researcher­s also acknowledg­e that there is a risk for reverse causation. This was also data gathered from one country, meaning that the outcomes might be slightly different in other countries, for better or worse.

Eduardo Nilson noted that they could work to apply the data they collected in other areas and other countries: “We look forward to estimating the impact of UPF in other countries, modeling the impacts of different policies and interventi­ons (dietary counseling, UPF taxation, front-of-package labeling, regulation of food publicity, etc.), developing models for specific health outcomes (such as cardiovasc­ular diseases, diabetes, obesity), incorporat­ing health economic analyses to the models and improving the models to forecast the impacts of policy interventi­ons.”

Making healthier food choices

It is unknown how exactly changes to food policies and recommenda­tions at national and internatio­nal levels could affect the health of entire population­s.

In the meantime, people can work with their doctors and nutrition specialist­s to cut down on personal consumptio­n of ultra-processed foods as appropriat­e.

“Start by reducing (eventually eliminatin­g) sodas, chips, cookies, fried foods, and junk,” Gomer said.

“Replacing junk food with whole foods is key. Sit down to meals instead of eating on the run and make the time and effort to prepare healthy food at home. Challenge yourself to small changes. Replace a few unhealthy foods with healthy ones.”

All said, Nigerians should learn from the Brazilian experience and focus more on the consumptio­n of our local diets. As one has severally highlighte­d, through my foodforhea­lthng.blog, there is evidence-based nutrition.

That means that we live healthier and longer by eating the locally available yam processed as pounded yam, cassava transforme­d into amala, eba; rice as tuwo. These can be taken along with the local delicacies, especially those cooked using vitamin-a richpalm oil, gbegiri,edikaikong, ugu, or eforiro. That does us a world of immense good instead of the fried,fatty foreign foodstuff that lead to high blood pressure or other debilitati­ng diseases.
