Are you on a quest to know the most common additives in processed foods? then my friend, you are in the right place.
Food additives include substances added to food to make it safer, fresher, tastier, better textured, or more visually appealing.
Many processed foods contain a variety of additives for these purposes. While some additives are natural and harmless, others are artificial and controversial in terms of their health effects.
This article explores some of the most common food additives found in processed foods and provides an overview of their purported health risks and benefits.
Food additives preserve and enhance the appeal of food. With the rise of processed foods in the 20th century, the use of additives dramatically increased as companies sought to maximize the shelf life and palatability of their products.
Today, it’s estimated that there are over 10,000 substances added to foods. However, the long-term effects of many of these additives are not fully understood.
Below we’ll explore 11 of the most ubiquitous food additives found in processed foods, looking at what they are, why they’re used, and potential concerns about each one:
MSG (Monosodium Glutamate)
MSG is a common flavor enhancer added to foods like canned soups, salad dressings, seasoning mixes, and frozen dinners to amplify the natural taste. This additive is known to intensify the savory umami flavor and allows manufacturers to use less salt.
However, MSG remains controversial. A condition called “Chinese Restaurant Syndrome” was first coined in 1968 to describe symptoms like headaches, flushing, and heart palpitations experienced by some people after eating MSG-laden Chinese food.
While multiple studies have failed to conclusively prove that MSG is harmful, negative reactions seem to occur in a small subset of individuals who are sensitive to its effects.
High-Fructose Corn Syrup
High-fructose corn syrup (HFCS) is made from corn starch and used to sweeten sodas, fruit juices, candies, desserts, condiments, and other processed foods. It’s cheaper to produce and sweeter than traditional sugar.
However, regular consumption of HFCS may contribute to obesity, liver disease, diabetes, and cardiovascular disease. Some evidence also suggests that fructose fails to stimulate hormones like insulin, leptin, and ghrelin, which help regulate appetite. This could encourage overeating.
Trans Fats
Trans fats, or trans fatty acids, are created by adding hydrogen to liquid vegetable oils to turn them into solid fats, like shortening or hard margarine. Products made with trans fats have a longer shelf life and more consistent taste and texture.
However, trans fats significantly raise levels of LDL (bad) cholesterol and lower HDL (good) cholesterol, increasing risk of heart disease, stroke, and type 2 diabetes. For this reason, the FDA banned the use of partially hydrogenated oils, the main source of trans fats, as of June 2018.
Sodium Nitrite and Nitrate
Sodium nitrite and nitrate are used to preserve processed and cured meats like bacon, ham, lunch meats, hot dogs, and corned beef. They prevent bacterial growth and give cured meats their characteristic red color and smoky flavor.
However, during digestion nitrites can combine with compounds called amines to form nitrosamines, which are powerful cancer-causing chemicals linked to colorectal, stomach, and pancreatic cancer. There are also concerns that sodium nitrite may cause DNA mutations.
Artificial Coloring
Artificial food colorings like Red 40, Yellow 5, and Yellow 6 are added to many processed foods to restore color lost during processing or make foods and drinks more visually appealing. Studies have linked artificial coloring to hyperactivity and behavior problems in children. There are also concerns that food dye yellow 5 may aggravate asthma and other allergies.
Artificial Sweeteners
Artificial sweeteners like aspartame, sucralose, and saccharin are used in “diet” and “sugar-free” products to provide the sweetness of sugar without the calories. They’re found in soft drinks, yogurts, ice cream, candy, gum, and other processed foods.
While better than sugar for people with diabetes, artificial sweeteners are controversial. Some studies associate them with weight gain and increased appetite, while others link them to cancer or neurological effects like depression and migraines in sensitive individuals.
Sodium
Sodium, usually in the form of table salt, is the most common food additive used to flavor and preserve processed foods. High sodium intake is linked to high blood pressure, which raises the risk of stroke, heart attack, and other health issues. The average American consumes around 3,400 mg of sodium per day, much higher than the 2,300 mg limit recommended.
Phosphates
Phosphates like mono- and diglycerides are emulsifiers and leavening agents used to improve texture and prevent crystallization in processed meats, cheeses, baked goods, powdered foods, and soda. However, phosphates may promote heart disease, chronic kidney disease, and osteoporosis. They’re also linked to accelerated aging.
Guar Gum
Guar gum is a thickener extracted from guar beans used to improve the texture and shelf life of processed foods like yogurt, soups, puddings, sauces, and salad dressings. It provides a creamy “mouthfeel” but is very high in fiber, which can cause gas, diarrhea, and abdominal pain when over-consumed.
Guar also contains FODMAPs, which some people with irritable bowel syndrome (IBS) and other digestive conditions may be sensitive to.
Carrageenan
Carrageenan is a thickener and emulsifier extracted from red seaweed that helps improve the texture of processed foods like nut milks, yogurt, cottage cheese, ice cream, and deli meats. Degraded forms of carrageenan may cause colon inflammation, ulcers, and cancer in animal studies. More research is needed.
Some research suggests that carrageenan may cause digestive problems, like bloating and gas, in sensitive individuals. It’s best to avoid it if you have IBS or other digestive issues.
Preservatives
Preservatives like sodium benzoate, sulfur dioxide, sodium bisulfite, and sodium metabisulfite are added to foods to prevent bacterial growth and mold. They’re found in vinegar, processed fruits, pickled foods, soft drinks, and fruit juices. Preservatives may trigger asthmatic symptoms and other allergic reactions in those who are sensitive.
An academic investigation of the most common food additives in processed foods reveals that many of these ingredients are linked to various health issues, such as cancer, hyperactivity, behavior problems, weight gain, and digestive problems.
If you’re concerned about the potential health effects of food additives, it’s best to limit your intake of processed foods and read food labels carefully.
Should You Avoid Processed Food Additives?
While the negative health effects of some food additives like trans fats are clear, more research is still needed to fully understand the impact of many common food additives. Some individuals also seem more prone to adverse reactions than others.
Rather than trying to eliminate all processed food additives, which is unrealistic for most people, the FDA recommends checking labels and minimizing intake of foods with additives you want to avoid when possible. As with many nutrition topics, moderation is key.
Additionally, focusing your diet on whole, unprocessed foods like fruits, vegetables, lean proteins, whole grains, legumes, nuts and seeds will help limit your exposure to potentially harmful additives, especially when combined with making fresh, homemade alternatives to many processed foods.
Key Takeaways:
- Many processed foods contain additives like MSG, high-fructose corn syrup, trans fats, sodium nitrite, artificial coloring, artificial sweeteners, sodium, and more.
- Certain food additives may promote health issues like obesity, cancer, diabetes, and heart disease, especially when consumed in excess.
- Individual sensitivities and reactions vary – some people experience negative side effects from additives, while others appear unaffected.
- Check labels and minimize intake of processed foods with controversial additives when possible.
- Focus diet on whole, unprocessed foods to limit additive exposure. Moderation is key, as occasional processed foods in small amounts are unlikely to be harmful.
