Ultraprocessed Food Leads to Premature Aging

An article in the medical journal “Medical News Today” found that ultraprocessed food leads to premature aging.

What are ultraprocessed foods?

The NOVA Food Classification System explains what ultraprocessed foods (UPFs) are and what other ones are not. Examples of ultraprocessed foods are: fatty, sweet, savory or salty packaged snacks, pre-prepared poultry and fish ‘nuggets’ and ‘sticks.’ Others are cola, soda and other carbonated soft drinks, pastries, cakes and cake mix. Generally speaking, the food processors add too much salt, sugar and saturated fat. They often also add food preservatives, coloring, and flavor enhancers.

What do ultraprocessed foods cause?

Sugary beverages lead to blood sugar peaks and insulin surges. This in turn can cause type 2 diabetes later on. Melanie Murphy Richter, MS, RDN, a registered dietitian nutritionist said that “overly salty snacks like chips, crackers, and instant noodles, and other UPFs with trans fats and hydrogenated oils all should ideally be avoided”. Read labels before you buy any food product.  Hydrogenated oils and trans fats are increasing LDL cholesterol leading to premature hardening of the arteries. This can cause strokes and heart attacks.

Hot dogs, sausages, and deli meats contain nitrates and nitrites as preservatives. This can form carcinogenic compounds like nitrosamines during cooking or metabolism. The World Health Organization (WHO) has classified processed meats to contain Group 1 carcinogens.  These processed meats also contain high amounts of sodium and saturated fats. This causes high blood pressure and cardiovascular disease.

Telomere length reduced by ultraprocessed foods

Another study regarding consumption of ultraprocessed foods came out in 2020. There were 886 participants aged 57–91. Researchers measured telomere length in saliva samples. Subjects with the highest UPF consumption had almost twice the odds of having short telomeres in comparison to those with the lowest UPF consumption. Patients with shorter telomeres were much more prone to chronic diseases like cancer and cardiovascular disease. The overall death rate was much higher in patients with shorter telomeres. This confirms what another study also found.

Ultraprocessed foods are causing obesity and weight gain

Another study found that ultraprocessed foods caused weight gain and obesity. The authors of this study pointed out that US residents eat up to 70% of the total calorie input as UPFs. They reviewed the literature and found that UPF consumption raises the risk of obesity. Also, chronic conditions like cancer, strokes, heart attacks, type 2 diabetes and depression are directly linked to UPF consumption. Because of the development of these chronic health conditions the life expectancy is about 10% shorter than for those who don’t consume UPFs.

Conclusion

Over the past several decades food companies produced more and more ultraprocessed foods (UPFs). You see them on grocery store shelves. They contain high amounts of sugar, saturated fat and salt. This can cause cardiovascular disease. Added food preservatives, coloring, and flavor enhancers are also of concern as they may lead to UPF food addiction. Obesity, cancer, heart attacks and strokes are often the final result of UPF overconsumption. Another publication that I reviewed showed that consumption of UPF leads to shorter telomeres in all body cells. We know from other publications that short telomeres cause chronic diseases and premature deaths because of organ failures. The bottom line is that you want to reduce your UPF food intake and increase your whole food intake. This will strengthen your immune system, prevent heart attacks, strokes and cancer. Your telomeres will stay long and your life expectancy increases by about 6 years.

Too much Ultraprocessed Food Makes you sick

A Lancet study published on Nov. 13, 2023 found that too much ultraprocessed food makes you sick. Researchers noted that ultraprocessed animal products and sweetened beverages were linked to an increased cancer risk as well as other diseases such as strokes or diabetes.

In Europe more than half of the food intake consists of ultraprocessed food. In the US a 2019 study found that 71% of the food supply is ultraprocessed.

Details of the study

The details of the study were summarized in a CNN report. Researchers of the study collected nutritional data from 266,666 men and women (60% were women) from 7 European countries between 1992 and 2000. The researchers followed the participants for 11 years. During that time they observed the participants for the development of chronic diseases and cancer. During the observation time 21,917 primary cancers, 10,939 cardiovascular events, and 11,322 type 2 diabetes cases developed. On entry into the study participants were questioned about their food intake in the past 12 months. This was matched with the NOVA classification system. It became clear that not all ultraprocessed foods were detrimental to the health of the participants. Animal products and sugar-sweetened drinks and foods caused chronic diseases in the participants of the study. However, ultra-processed breads, cereals or alternative plant-based products were neutral in terms of health risks.

Main findings of the study: too much ultraprocessed food makes you sick

The main findings of the study were that ingesting mostly ultraprocessed food leads to a 9% increase of heart attacks, strokes, diabetes and cancer. This is in comparison to controls who ate very little ultraprocessed food. However, when you reduce your intake of ultraprocessed food your risk of developing these diseases reduces. The key is to eat more fruit and vegetables and concentrate on eating minimally processed food.

Other studies with similar findings

In 2022 the British Medical Journal published two studies that documented a higher colorectal cancer rate and cardiovascular disease rate when subjects were eating larger amounts of ultraprocessed foods (UPF). Specifically, when men had exposure to a high percentage of UPF in their diet they developed 29% more colorectal cancer after 28 years of observation in comparison to men who ate a low percentage of UPF. A related study that went on for 14 years showed a 32% higher risk for death from cardiovascular disease for men who ate a high UPF diet in comparison to men on a low UPF diet.

French study 2019

A French study in 2019 followed 44, 551 French adults 45 years or older for 7.1 years. A 10% increase of consumption of ultraprocessed food caused a 14% higher risk of all-cause mortality. The authors stated that 80% of all premature deaths from noncommunicable disease are due to cardiovascular disease (CVD), respiratory disease, cancer, and diabetes. The authors discussed in detail the problems with overconsumption of ultraprocessed food.

Some of the contents of ultraprocessed food

Ultraprocessed food contains:

  • High salt content, and high sodium intake has been associated with cardiovascular deaths and increased stomach cancer risk.
  • Excessive amounts of added sugar. There is an association between added sugar consumption and an increased risk of mortality from cardiovascular disease.
  • Ultraprocessed foods contain very little fiber. More dietary fiber in one’s diet has an association with lower death rates.
  • Studies have estimated that reducing saturated and trans fats, salt, and added sugar in the diet prevent cardiovascular deaths.
  • High temperature food processing produces acrylamide. Acrylamide is a known carcinogen.
  • Consumption of processed meat products causes a higher risk of colorectal cancer and stomach cancer.
More ingredients of ultraprocessed food
  • Artificial sweeteners can alter microbiota and can cause the onset of type 2 diabetes and metabolic diseases.
  • With bisphenol A coating in food packaging endocrine disruptors enter the food. Bisphenol A causes endocrine cancers and metabolic diseases, such as diabetes and obesity.
  • The food industry uses additives frequently in their formulations. Some studies raised concerns about the health consequences of food additives. For instance, the food industry uses titanium dioxide widely. There is an association of titanium dioxide and increased risk of chronic intestinal inflammation and carcinogenesis.

It is easy to see that when we expose our bodies to a mix of these ingredients this can cause cardiovascular diseases, cancers and diabetes. The final outcome is that this leads to premature deaths.

Too much Ultraprocessed Food Makes you sick

Conclusion

Too much ultraprocessed food (UPF) makes you sick. This is the conclusion of a large study, which the Lancet published on Nov. 13, 2023. Researchers followed 266,666 men and women (60% women) for 11 years. The main findings of the study were that ingesting mostly ultraprocessed food leads to a 9% increase of heart attacks, strokes, diabetes and cancer. This is in comparison to controls who ate very little ultraprocessed food. Other studies going back to 2019 and 2022 showed very similar findings.

Other studies

A French study from 2019 noted that a 10% increase of consumption of ultraprocessed food caused a 14% higher risk of all-cause mortality. Several studies in 2022 showed that men who had an exposure to a high percentage of UPF in their diet developed 29% more colorectal cancer after 28 years of observation in comparison to men who ate a low percentage of UPF. A related study that went on for 14 years showed a 32% higher risk for death from cardiovascular disease for men who ate a high UPF diet in comparison to men on a low UPF diet. It follows from this data that a simple diet consisting of vegetables, fruit, nuts and lean meat (chicken turkey, fish) with minimal amounts of UPF protects you from premature death.

Ultraprocessed Food Kills

The British Medical Journal published two papers that showed that ultraprocessed food kills. The first paper showed that highly processed food causes heart attacks and strokes. Another paper in the same journal showed that mortality is significantly increased when people consume highly processed food. Both papers were reviewed by CNN.

Food categories

Food questionnaires were administered over 24 hours every 2 years from every participant using the NOVA classification system.

There were 4 categories.

  • Category 1 consisted of “unprocessed or minimally processed” food. This included legumes, vegetables, fruits, milk, eggs, meats, poultry, fish and seafood, yogurt, grains and natural juice.
  • Next was category 2 of “processed ingredients”. This included salt, sugar, honey, olive oil, butter and lard.
  • Category 3 consisted of “processed foods“. This included breads, cheeses, beer, wine, and cured traditional ham and bacon.
  • Finally, category 4 consisted of “ultraprocessed foods”. This included sausages, flan, chorizo, mayonnaise, pizza, cookies, potato chips, chocolates candies, artificially sweetened beverages including whisky, gin and rum.

Study on cardiovascular risk

A study from France followed more than 105,000 people for 5.2 years. The participants filled out food questionnaires every 6 months. The foods consumed were classified according to the NOVA categories. The results showed that the men’s diet consisted to 17.6% of heavily processed foods while the diet of women consisted of 17.3% heavily processed food. Each 10% increment of highly processed food (called “ultraprocessed” food) had an association with 12% higher risk of cardiovascular disease, 13% more heart attacks and 11% more strokes. The researchers could also show that a decrease in ultraprocessed food was leading to less percentage of these diseases.

Mortality risk when consuming ultraprocessed food

A similar study involving close to 20,000 participants in Spain that had a long observation time of 15 years (from 1999 to 2014). The 4 food categories were as mentioned above.

A person eating more than 4 ultraprocessed items per day or more had a 62% increase of death rate in comparison to those who ate processed food less frequently. Each additional ultraprocessed food item added another 18% of mortality risk. Maira Bes-Rastrollo, professor of Preventive Medicine and Public Health at Universidad de Navarra, Medical School said: “These results are in agreement with other recent results based on populations in France and the United States. If all the different study results align, despite the separate research groups using dissimilar populations, diverse age ranges and different methodologies, then this lends support to a possible cause-effect relationship between ultraprocessed foods and poor health.”

Discussion

You may remember that your grandparents reminded you not to eat “junk food”. Often junk food is consisting of ultraprocessed foods. Both of these independent studies from France and from Spain have shown that there is a significant risk of heart attacks and strokes associated with the consumption of ultraprocessed foods. In addition, there is also a significant mortality risk when you consume ultraprocessed food. The key is to learn from this and cut down on processed foods; instead eat foods that are less processed and are wholesome for you. Eat vegetables, fruit, nuts and stay away from the grocery store’s shelves with processed foods.

Ultraprocessed Food Kills

Conclusion

What your grandparents used to tell you about processed foods is now available as two separate publications from the British Medical Journal. The less processed food you consume, the healthier your food intake is. You will enjoy better health. This is the simple message. Avoiding ultraprocessed food will help you to avoid heart disease, heart attacks and strokes. In addition you will have a longer life expectancy. It is up to us to translate these findings into reality for ourselves.
