The Realities of Ultra Processed Food
Ultra-processed foods (UPFs) have become a staple in modern diets, making up a significant proportion of what we eat. They are convenient, tasty, and readily available, but they also come with a range of health risks that cannot be ignored. Any nutritionist in Dubai would provide you with many warnings about the nature and impacts these types of foods can have on the human body.
UPFs are often high in sugar, salt, and fat, and lack the essential nutrients that our bodies need to function properly. They are made from cheap, artificial ingredients, and often contain additives that can harm our health.
In this blog article we will examine the science behind ultra processed foods, including the most recent peer reviewed studies and the key conclusions reached in them and what implications these have for the everyday diet of parents, children, men and women.
The Science of Ultra Processed Foods
Ultra Processed Foods are made from a combination of ingredients that have been heavily processed, including refined sugars, oils, flours, and additives.
These ingredients are often stripped of their original nutritional content during processing, leaving behind a product that is low in essential nutrients and high in calories. Studies have shown that the processing of foods can lead to a reduction in vitamins and minerals, including folate, vitamin C, and iron.
UPFs can also have a negative impact on our gut microbiome, the community of microorganisms that live in our digestive system and play a crucial role in our health.
A study published in the journal Cell Metabolism found that a diet high in UPFs reduced the diversity of gut bacteria and led to an increase in inflammation in the body. This, in turn, can lead to a range of health problems, including obesity, diabetes, and heart disease.
RISKS ASSOCIATED WITH ULTRA PROCESSED FOODS
The health risks associated with UPFs are numerous and well-documented. Consuming a diet high in UPFs has been linked to an increased risk of obesity, cardiovascular disease, cancer, and more. A study published in the British Medical Journal found that those who consumed the most UPFs had a higher risk of cardiovascular disease, regardless of other factors such as age, sex, and smoking status.

Aspartame
Aspartame is an artificial sweetener that is commonly used in diet sodas, chewing gum, and other low-calorie foods. It has been linked to headaches, dizziness, and neurological symptoms such as seizures, memory loss, and depression.
A study published in the Journal of Molecular Biology in 2015 found that aspartame can increase the expression of HSP70 and alter the expression of Bcl-2 and BAX.
The study was conducted in vitro using human kidney cells and involved exposing the cells to aspartame at different concentrations.
The researchers found that aspartame caused an increase in the expression of HSP70, which is a heat shock protein that is upregulated in response to cellular stress. They also found that aspartame altered the expression of Bcl-2 and BAX, which are proteins that are involved in regulating cell death. The researchers concluded that the findings suggest that aspartame may have cytotoxic effects on human cells.

Cinnamaldehyde
Cinnamaldehyde is a naturally occurring compound found in cinnamon, which has been used for medicinal purposes for centuries. In moderate amounts, cinnamaldehyde is generally considered safe, however it can have adverse effects if consumed in excessive amounts or in certain individuals who are sensitive to it. Some studies suggest that high doses of cinnamaldehyde may be toxic to liver cells and may cause liver damage in certain individuals and may interfere with other biological pathways and potentially have negative effects.
A study published in the Journal of Cellular Biochemistry in 2017 found that cinnamaldehyde can block the activation of nuclear factor-kappa B (NF-κB) and decrease the signaling of tumor necrosis factor-alpha (TNF-α) and interleukin-10 (IL-10). The study was conducted on human umbilical vein endothelial cells (HUVECs) and suggested that cinnamaldehyde may have potential anti-inflammatory effects by modulating the expression of pro-inflammatory cytokines.

Colorant Curcumin
Curcumin is a food additive that is commonly used as a colorant in various food products, including dairy, baked goods, and beverages. It is derived from turmeric and has been found to have antioxidant and anti-inflammatory properties in studies conducted on animals and in vitro. However, there is limited evidence to support its efficacy in humans, and more research is needed to determine its potential benefits and risks.
There have been several studies investigating the effects of colorant curcumin on the human body. One study found that it can inhibit the production of IL-10 and IFN-Y and downregulate the levels of IL-6 and TNF-A.
IL-10 is an anti-inflammatory cytokine that plays a critical role in regulating immune responses. IFN-Y is an inflammatory cytokine that is involved in the body's defense against infections. IL-6 and TNF-A are also pro-inflammatory cytokines that play a key role in the body's immune response.
The inhibition of IL-10 and IFN-Y and the downregulation of IL-6 and TNF-A levels may have negative effects on the human body. A decrease in IL-10 levels can lead to an overactive immune response and chronic inflammation, which can contribute to the development of various diseases, such as autoimmune disorders and cancer. The downregulation of IL-6 and TNF-A levels can also have negative effects on the body, as these cytokines are involved in many important physiological processes, including the regulation of metabolism and the immune response.
The effects of colorant curcumin on cytokine production may vary depending on the dose and duration of exposure, as well as individual factors such as age, health status, and genetics. Further research is needed to fully understand the potential health effects of colorant curcumin.

Monosodium Glutamate
Monosodium glutamate (MSG) is a food additive commonly used to enhance the flavor of savory dishes. It is a form of glutamic acid, an amino acid that is naturally found in some foods, such as tomatoes and cheese.
One of the main concerns with MSG is its potential to cause adverse reactions in certain individuals. This includes symptoms such as headache, sweating, flushing, and palpitations, collectively known as "MSG symptom complex" or "Chinese restaurant syndrome." While the exact mechanisms behind these reactions are still not fully understood, it is thought to be related to the way MSG interacts with glutamate receptors in the brain. Other studies have shown that excessive consumption of MSG may lead to increased oxidative stress in the body, which can damage cells and contribute to the development of chronic diseases such as heart disease, diabetes, and cancer. MSG may also have negative impacts on the gut microbiome, which plays a critical role in maintaining overall health. Some animal studies have also suggested that long-term consumption of MSG may have negative effects on the brain, such as impaired memory and cognitive function.
A study published in the Journal of Neuropathology and Experimental Neurology, found that MSG could destroy nerve cells in the brain of newborn mice, leading to brain damage and developmental problems. Another published in the journal Food and Chemical Toxicology, found that MSG consumption could increase hyperactivity and decrease cognitive function in rats. The researchers observed that MSG consumption caused alterations in brain structure and function, which could have negative effects on behavior. Another study, published in the Journal of Food Science, found that MSG exposure could have toxic effects on neutrophils, which are important immune cells that play a role in fighting infections. The researchers observed that MSG exposure caused a decrease in neutrophil viability and an increase in oxidative stress.

Nitric Oxide
Excessive consumption of nitric oxide has been linked to the formation of potentially harmful compounds called N-nitroso compounds (NOCs). These compounds are formed in the stomach when nitric oxide reacts with amino acids, particularly when foods containing nitric oxide are also high in protein.
Whilst nitric oxide (NO) is a molecule that is naturally produced in the body and plays a role in various physiological processes, a study published in the Journal of Immunology Research found that nitric oxide has anti-inflammatory and immune suppressive effects and can regulate the expression of various cytokines such as IL-1, IL-6, IL-8, IL-10, IL-12, IL-18, IFN-Y, and TGF-B. The regulation of these cytokines can have negative impacts on the body, as it can impair the immune system's ability to respond to infections and illnesses.
Excessive consumption of nitric oxide in the form of processed meats has also been linked to an increased risk of developing cardiovascular disease. This is because nitric oxide can react with compounds in the body to form reactive nitrogen species, which can cause damage to the endothelial cells lining blood vessels and contribute to the development of atherosclerosis.

Propionic Acid
Several studies that have investigated the negative effects of propionic acid on the body. One such study found that propionic acid can lead to behavioral changes and alter gene expression in the brain. Another study found that propionic acid can suppress the expression of certain cytokines, including IFN-Y, TNF-A, IL-4, and IL-10, which are important for immune function and inflammation. These findings suggest that excessive consumption of propionic acid may have negative effects on both the nervous and immune systems.
IFN-Y, TNF-A, IL-4, and IL-10 are all cytokines - small proteins released by immune cells that play an important role in regulating the immune response.
IFN-Y is primarily involved in activating immune cells such as macrophages and natural killer cells, which help to fight off infections and cancer cells. It also plays a role in regulating inflammation.
TNF-A is also involved in regulating inflammation, and it is produced by a variety of immune cells in response to infection, injury, or other types of stress. It can promote cell death and tissue damage if produced in excess.
IL-4 is involved in stimulating the production of antibodies by B cells and is also involved in the development of T helper 2 (Th2) cells. Th2 cells play a role in defending against parasites and are involved in allergic responses.
IL-10 is an anti-inflammatory cytokine that helps to dampen down the immune response and prevent excessive inflammation. It is produced by a variety of immune cells and can act locally or systemically to limit immune activity.
Propionic acid suppressing the expression of these cytokines could lead to a dysregulated immune response, leaving the body vulnerable to infection, cancer, and chronic inflammation.
Reduced levels of IL-10 could lead to an excessive inflammatory response, potentially causing tissue damage and contributing to chronic diseases such as arthritis and inflammatory bowel disease.

Sodium Benzoate
A study entitled "Sodium benzoate, a food preservative, affects the functional and activation status of THP-1 human monocytes" found that sodium benzoate can inhibit the TH-1 immune response, which is responsible for fighting off intracellular pathogens such as viruses and certain bacteria. This can weaken the body's ability to fight infections and increase the risk of developing chronic diseases.
Sodium benzoate can modulate the levels of certain cytokines, including NF-kB, TNF-A, and IL-1B. These cytokines play important roles in the body's immune response, inflammation, and cell growth. NF-kB regulates the expression of genes involved in immune and inflammatory responses, while TNF-A and IL-1B are pro-inflammatory cytokines that help to fight off infections and promote tissue repair. However, when overproduced, these cytokines can contribute to chronic inflammation, which is linked to many diseases such as cancer, heart disease, and autoimmune disorders.
The ability of sodium benzoate to inhibit TH-1 response and modulate these cytokines can be detrimental to overall health & the study suggests that the use of sodium benzoate as a food preservative should be carefully monitored and limited.

Sodium Nitrite
Sodium nitrite is a food additive commonly used as a preservative and color fixative. Research has shown that sodium nitrite exposure can increase the levels of TNF-A and IL-1B in testicular tissue and enhance NK cytotoxicity. TNF-A and IL-1B are pro-inflammatory cytokines that play a role in the immune system's response to infections and tissue damage. However, excessive production of these cytokines can lead to chronic inflammation and tissue damage, potentially contributing to the development of chronic diseases such as cancer, diabetes, and cardiovascular disease.
Enhanced NK cytotoxicity can lead to damage of healthy cells and tissues, contributing to tissue damage and inflammation. This increased cytotoxicity may also affect the normal function of the immune system and increase the risk of developing autoimmune diseases. Several studies have shown the potential harmful effects of sodium nitrite in the body, including its ability to induce oxidative stress, impair DNA repair mechanisms, and damage cell structures. Therefore, it is essential to limit or avoid the consumption of food products that contain high levels of sodium nitrite to reduce the risk of these negative health outcomes.

Sodium Sulfite
Sodium sulfite is a food preservative that has been shown to modulate the release of leptin in the body. Leptin is a protein hormone that is involved in the regulation of energy balance and appetite. High levels of leptin signal to the brain that the body has enough energy stores, while low levels signal that the body needs to consume more food.
In the body, the cytokine IL-6 is involved in the regulation of immune responses and inflammation. High levels of IL-6 have been associated with chronic inflammation and various diseases. Sodium sulfite has been shown to modulate the release of leptin in response to both high and low levels of IL-6.
This modulation of leptin release by sodium sulfite can have negative impacts on the body. Abnormal levels of leptin can lead to disruptions in energy balance and appetite regulation, which can contribute to the development of obesity and other metabolic disorders. Additionally, alterations in IL-6 levels can lead to dysregulation of the immune system and chronic inflammation, which can contribute to the development of various diseases.

Sunset Yellow
Sunset yellow's chemical name is "disodium 6-hydroxy-5-[(4-sulfophenyl)azo]-2-naphthalenesulfonate", it is also known as "FD&C Yellow No. 6". Sunset Yellow is a food colorant that has been found to lower the expression of several important cytokines in the body, including IL-2, IL-4, IL-6, IL-17, IFN-B and TNF-B. These cytokines are involved in a variety of important immune system functions, including the regulation of inflammation, cell growth and differentiation, and the activation of immune cells.
IL-2, for example, is a cytokine that plays a key role in the activation and proliferation of T-cells, which are a type of white blood cell involved in immune defense. IL-4 is another important cytokine involved in the regulation of T-cell function, and is also involved in the development and differentiation of B-cells, another type of immune cell.
IL-6 is a cytokine involved in the regulation of inflammation and immune response, and is produced in response to infection or injury. It is also involved in the differentiation and activation of immune cells, including B-cells, T-cells, and macrophages.
IFN-B is a type of interferon, a family of cytokines that are involved in antiviral and antitumor immune responses, as well as in the regulation of inflammation. TNF-B is a cytokine that is involved in the regulation of immune cell proliferation and differentiation, as well as in the regulation of inflammation.

Tartrazine
The chemical name of Tartrazine is "Trisodium 1-(4-sulfonatophenyl)-4-(4-sulfonatophenylazo)-5-pyrazolone-3-carboxylate", it is also known as Yellow No. 5. It is a synthetic yellow azo dye used in many processed foods, medications, and cosmetics. Studies have shown that tartrazine can cause adverse reactions in people who are sensitive or allergic to it.
Tartrazine can trigger allergic reactions such as hives, itching, swelling of the lips, tongue, and throat, difficulty breathing, and anaphylaxis in some people. It has also been associated with hypersensitivity and asthma exacerbations. Tartrazine's mechanism of action is not entirely clear, but it is believed to act as an irritant or sensitizer by binding to specific cell receptors in the immune system.
In addition to its potential effects on the immune system, tartrazine has also been linked to behavioral changes and hyperactivity in children. This is thought to be due to its ability to increase the release of histamine in the brain, which can cause changes in behavior and mood.
