These chemicals are found in highly processed foods and are used as carriers to extend shelf life and improve appearance. But growing scientific evidence shows that many of these additives are linked to adverse health effects. Knowing what these chemicals are and what they can do in our bodies is important so we can make informed choices and choose more nutritious foods for a safer and healthier body.
One of the most commonly used and frequently used herbicides is glyphosate, and in many cases this chemical has been linked to genetically modified foods such as soybeans, corn, and wheat. It is also found in smaller amounts in inorganic grains and some fruits and vegetables. Although its main function is to eliminate weeds, processed foods can contain glyphosate residue. Long-term use of the substance has raised concerns about its possible link to cancer and hormonal dysfunction, leading some health authorities to classify it as a possible human carcinogen. Although one meal may only provide a small amount, eating frequently increases the long-term risk. According to a study published in Frontiers, glyphosate is said to have the potential to treat everything from neurological disorders to inflammatory disorders.Artificial sweeteners such as aspartame, sucralose and saccharin are found in diet soft drinks, fat-free foods and most processed foods. They are designed to provide sweetness without adding calories. Several large-scale studies have found that high intake of artificial sweeteners is associated with changes in the gut microbiome, which in turn affect insulin sensitivity and glucose metabolism. Studies have identified potential links to the risk of cardiovascular disease and even depression in adults. Although these sweeteners minimize sugar spikes, their long-term metabolic effects remain controversial, especially in children who consume these foods most frequently. One such study published in PMC noted that regular consumption of ASB was associated with an increased risk of vascular diseases including stroke, diabetes, and dementia, even after adjusting for vascular disease risk factors.Sodium nitrite and nitrate are found in hot dogs, sausages, bacon, cold cuts, etc. It is used in processed meats. This is done to preserve color and prevent bacterial growth. When these chemicals are exposed to high temperatures, they suddenly begin to form acid in the stomach, converting into nitrosamines, potent substances that have been found to increase the risk of certain cancers in laboratory studies. Population studies also show that increased rates of processed meat consumption are associated with increased rates of gastric and colorectal cancer. As noted in a recent meta-analysis published by Springer Nature, it confirms an 18% increase in cancer incidence following consumption of processed foods. In some cases of oral exposure, research at the NIH noted that ingestion of nitrites (from potassium nitrite or sodium nitrite sources) was associated with severe methemoglobinemia in adults and children.MSG is a flavor enhancer known to bring out meat and all its umami flavors. It is found in prepared soups, frozen meals, and many snacks labeled “healthy.”Although most people can tolerate MSG without symptoms, some people experience headaches, facial flushing or nausea when consuming MSG. Chronic or excessive consumption may cause mild neurological symptoms in people hypersensitive to MSG, but the overall health effects remain controversial. A study published in the NIH notes that preclinical studies have linked MSG use to cardiotoxicity, hepatotoxicity, neurotoxicity, low-grade inflammation, and metabolic disorders.Synthetic food colorings such as Red 40, Yellow 5 and other artificial dyes are used to enhance the visual appeal of snacks, drinks and desserts and are often thought to cause behavioral disorders, especially in children with attention problems. Some color additives are being studied for possible links to allergic reactions and possible carcinogenicity. Experts and regulators oppose reducing consumption of food products containing artificial food dyes. A study published in the journal Environmental Research and Public Health says synthetic dyes in food can be harmful to children, causing problems such as hyperactivity, behavioral problems, allergies and even more serious health problems. Children with conditions such as ADHD or autism may experience more severe symptoms, while even healthy children may suffer cognitive, behavioral or nutritional effects.
