Food additives are ubiquitous; they can be found in many foods and almost every prepackaged food.
They are substances added to food to enhance its flavor, appearance, texture or shelf life. While some food additives are simply unhealthy at their best, others have the potential to cause negative health effects and should be avoided or limited.
We’ve compiled a list of the 12 worst food additives. Today we’ll dive into the first six (we don’t want this scary food data to overwhelm you, after all!).
Let’s get started.
01
MSG
What is it?
Monosodium glutamate (MSG) is derived from L-glutamic acid, an amino acid found in your body and many foods. It’s a popular food additive used to enhance flavor and can be used to reduce overall sodium intake when used in place of salt.
MSG boosts the flavor of foods by stimulating taste receptors and has been shown in research studies to increase the acceptance of particular flavors. Adding MSG to foods results in an umami taste, which is characterized as savory and meaty.
What can it do?
Some of the physical symptoms tied to long-term consumption of MSG include:
- Headache
- Flushing and sweating
- Face pressure or tightness
- Numbness, tingling or burning in the face, neck and other areas
- Quick, fluttering heartbeats and chest pain
- Nausea and weakness
Where’s it found?
- Fried chicken
- Pizza
- Sausage
02
Artificial food coloring
What is it?
Artificial food coloring is used to enhance the color of food. (Go figure!) It’s … everywhere.
What can it do?
- Allergic reactions
- Possibly increase the risk of cancer
- Hyperactivity in children
Regarding that last point: the evidence is mostly based on animal studies and no human trials have confirmed these links.
Where’s it found?
- Candy
- Popsicles
- Sports and soft drinks
- Cereals
- Chips
- Ice cream
03
Sodium nitrite
What is it?
Sodium nitrite is a chemical compound that is used as a preservative and a color enhancer in some processed and cured meats, cheese, fish, and also certain medications.
Sodium nitrite can prevent the growth of harmful bacteria, such as Clostridium botulinum, which causes botulism.
What can it do?
- Increased risk of pancreatic and colorectal cancer
- Shortness of breath
- Headache
- Nausea
- Fatigue
- Rapid heart rate
- Confusion
- Dizziness
- Cyanosis (bluish skin and lips)
- If inhaled or absorbed through the skin, it can irritate the eyes, skin, nose, and throat
Where’s it found?
- Bacon
- Ham
- Salami
- Hot dogs
- Corned beef
- Pastrami
- Pepperoni
- Bologna
- Sausages
- Canned meat
- Smoked fish
04
Partially hydrogenated vegetable oil
What is it?
Partially hydrogenated vegetable oil is a type of fat that is created by adding hydrogen atoms to liquid vegetable oil, making it more solid at room temperature. This process also produces trans fats, which are harmful for the health of the heart and blood vessels.
According to the U.S. Food and Drug Administration (FDA), partially hydrogenated oils are no longer “generally recognized as safe” and should be avoided as much as possible.
What can it do?
- Raises the levels of “bad” LDL cholesterol and lowering the levels of “good” HDL cholesterol, which increases the risk of heart disease and stroke
- Increased inflammation, which can contribute to chronic diseases such as diabetes, arthritis, and cancer
- Interfering with the function of essential fatty acids, which are needed for brain development, hormone production, and immune system regulation
Where’s it found?
- Baked goods such as cakes, cookies, pies, pastries, and doughnuts
- Margarine, shortening, and non-dairy creamers
- Snack foods such as potato chips, corn chips, crackers, and popcorn
- Fried foods such as french fries, chicken nuggets, and onion rings
- Frozen foods such as pizza, pies, waffles, and biscuits
05
High-fructose corn syrup
What is it?
Similar to but worse than table sugar, high-fructose corn syrup (HFCS) is a sweetener made from corn starch that is widely used in processed foods and beverages. It contains a mixture of glucose and fructose.
The high amounts of fructose in HFCS means it is metabolized differently than glucose and can cause more fat accumulation in the liver and blood. Fructose may also affect appetite regulation and increase the risk of overeating and weight gain.
What can it do?
- Obesity
- Diabetes
- Fatty liver disease
- Heart disease
- Inflammation
Where’s it found?
- Soda and fruit juice
- Breakfast cereal
- Bread and baked goods
- Candy
- Yogurt
- Ketchup
- Soup
- Canned fruit
06
BHA and BHT
What are they?
BHA (butylated hydroxyanisole) and BHT (butylated hydroxytoluene) are synthetic antioxidants that prevent fats and oils from going rancid. Also found in some cosmetics, BHA and BHT are used to preserve food color, flavor, and odor.
What can they do?
Some studies have suggested that BHA and BHT may have harmful effects on human health, such as
- Increased risk of cancer
- Liver damage
- Organ damage
- Disrupted hormone function
- Allergic reactions
Where are they found?
- Lipsticks
- Moisturizers
- Cereals
- Potato chips
- Chewing gum
- Butter
- Meats
- Beer
- Dehydrated potatoes
- Food packaging
- Animal feed
- Rubber and petroleum products
To avoid these harmful food additives, it’s best to read the ingredient labels carefully and choose natural, whole foods whenever possible. You can also look for organic or non-GMO certified products that are less likely to contain synthetic chemicals.
Stay tuned for next week and the conclusion of our list of the 12 worst food additives!


Hey Carla,
Thanks for your comment! Here are some meat alternatives to chicken and fish:
• Turkey
• Beef
• Pork
• Lamb
• Bison
All 5 are great sources of protein and are low in fat. They’re also rich in vitamins and minerals such as iron, zinc, and potassium. However, it is important to choose lean cuts to avoid consuming too much saturated fat.
Hope this helps!
Time to eat better
