Are Artificial Food Additives Harmful to Your Health?

Artificial meals components are artificial elements, that means they aren’t naturally derived, added to meals to reinforce its look, texture, style, and freshness (1).

Types of meals components

The FDA makes use of the next two classes of meals components (1):

  • Direct. These are added for a selected function, equivalent to texture, leavening, binding, or shade. For instance, aspartame is a well-liked synthetic sweetener used to enhance the style of sodas and low calorie or sugar-free meals.
  • Indirect. These could grow to be a part of meals in hint quantities resulting from packaging, storage, or different dealing with practices. In this case, producers should guarantee all packaging supplies are secure to be used.

For probably the most half, direct meals components are the main target of concern for customers. These could be additional categorized into the next two classes (1):

  • Natural. Natural components are derived from a pure meals supply. For instance, crimson beets are used to supply pure crimson meals coloring, whereas soybeans and corn are used to make lecithin — a sort of emulsifier — to bind elements.
  • Artificial. Artificial components should not derived from nature. For instance, most vanilla extracts are made out of vanillin, which is produced in a lab.

Both pure and synthetic meals components should meet strict regulatory and security pointers to be permitted to be used in meals (1).

Types of meals they’re generally present in

Artificial meals components are discovered in lots of standard meals, equivalent to yogurts, breads, salad dressings, sodas, baked items, chips, protein bars, and different processed foods.

In reality, many meals on grocery retailer cabinets comprise both pure or synthetic meals components in some type. Some meals could comprise emulsifiers, whereas others could comprise sweeteners or meals colorings (1, 2).

Unless a meals is totally unprocessed, equivalent to an apple, you should definitely read the label in the event you’re involved about any meals components.

Why they’re added to meals

Many meals merchandise comprise emulsifiers, stabilizers, or thickeners to enhance the standard of the product. These components assist bind elements, equivalent to oil and water, to supply a extra uniform texture and look (3).

A meals can also have synthetic components to enhance its dietary composition. For instance, artificial ascorbic acid (vitamin C) and folic acid (an artificial type of folate) are generally added to meals as a result of they’re extra secure than their pure counterparts (1, 3, 4).

Finally, meals producers could select to make use of synthetic meals components, as they’re normally decrease in value than pure meals components (1).


Artificial meals components are artificial elements added to meals to reinforce its look, texture, style, shelf life, freshness, and vitamin. They’re discovered in lots of meals, equivalent to breads, baked items, yogurts, salad dressings, chips, and drinks.

Despite the strict security protocols that synthetic meals components endure, customers could fear about these elements’ long-term well being results.

Gut well being

To date, there’s little proof that synthetic meals components permitted to be used by the FDA hurt your intestine well being or digestion (5).

That mentioned, the rise in intestine problems, equivalent to irritable bowel syndrome (IBS), Crohn’s illness, and intestine dysbiosis, together with the rise of extremely processed meals, has led many to wonder if there’s a connection between gut health and artificial food additives (6).

Some preliminary analysis in mice means that the consumption of synthetic sweeteners could decrease intestine micro organism range and theoretically result in digestive points — although no analysis instantly ties synthetic meals components to poor intestine well being in people (6, 7, 8).

Keep in thoughts that the human microbiome vastly differs from animals, which can result in variations in how synthetic sweeteners are metabolized.

As nicely, most of those research should not nicely managed and use considerably larger doses than these the common human would devour. Therefore, extra analysis is required.

Also, some mice research have proven that polysorbate 80 (an emulsifier) and titanium dioxide (a meals coloring) could result in alterations in gut microbiome range. Particularly, the rise in sulfate-reducing micro organism could exacerbate IBS signs (6, 8, 9, 10).

However, it’s unknown if these results apply to people, who’ve totally different digestive techniques than mice. Long-term human research are wanted to completely perceive synthetic meals components’ results on human well being (6, 7, 11).

If you imagine you could be delicate to sure meals components, it’s greatest to work with a healthcare skilled who makes a speciality of digestive problems.

Weight acquire

Artificial sweeteners are standard meals components, however whereas some use them as an answer to a excessive sugar weight loss program, others imagine they could do extra hurt than good.

Also referred to as nonnutritive sweeteners, artificial sweeteners comprise zero energy however add sweetness to meals and drinks. Popular varieties embody aspartame, acesulfame Ok, saccharin, and sucralose.

Despite containing zero energy, it’s thought that synthetic sweeteners could contribute to weight acquire by altering the intestine microbiome, resulting in modifications in metabolism and hormone regulation (12, 13).

However, most synthetic sweeteners don’t attain the decrease gut the place the intestine microbiome exists. Therefore, it’s unlikely that synthetic sweeteners would change the intestine microbiome, and no research have proven that synthetic sweeteners trigger weight acquire (12, 13).

In reality, one research discovered no distinction in intestine micro organism colonies when human customers consumed a traditional quantity (throughout the acceptable day by day consumption suggestions) of synthetic sweeteners (13).

Additionally, some theorize that synthetic sweeteners could not sign the discharge of hunger-regulating hormones in the identical method as sugar, resulting in elevated starvation and meals consumption (14).

That mentioned, associations should not the identical as trigger and impact. In many circumstances, different confounding elements (e.g., complete dietary consumption, historical past of weight-reduction plan, and bodily exercise) can even affect weight acquire or weight reduction.

Additionally, outcomes can range relying on the research design and which exterior elements are managed. Because of those variations, there was a substantial amount of conflicting analysis.

For instance, a lot of cross-sectional human research present a dose-dependent affiliation between synthetic sweetener consumption and physique mass index (BMI), but quite a few scientific trials and meta-analyses have proven synthetic sweeteners could support weight reduction (15, 16, 17, 18, 19, 20).

Additionally, a latest meta-analysis within the British Medical Journal confirmed no relationship between synthetic sweetener consumption and BMI. The authors concluded that larger high quality, long-term research are wanted (21).

All in all, continued analysis is warranted.


Some synthetic meals components could also be related to the next threat of sure kinds of most cancers.

In explicit, a weight loss program excessive in nitrites and nitrates, that are generally present in processed meats, has been linked to an elevated threat of colorectal most cancers (22).

In 2015, the World Health Organization categorized processed meat as carcinogenic to people resulting from elevated analysis displaying a dose-dependent relationship between processed meat consumption and colorectal most cancers threat (22).

Bisphenol A (BPA), an additive generally present in meals packaging, has additionally been linked to an elevated threat of most cancers and endocrine disruption. Though now banned in child merchandise, it may possibly nonetheless be present in some water bottles, cans, and different packaging (23, 24, 25, 26).

Limited analysis instantly connects different meals components to an elevated threat of most cancers. However, a extremely processed weight loss program is related to the next threat of most cancers total, although it’s unclear whether or not meals components play a task on this (27).

The best methods for reducing your cancer risk embody avoiding smoking, limiting your alcohol consumption, sustaining a wholesome physique weight, staying energetic, and following a nutritious weight loss program excessive in fiber, fruits, and greens (28, 29, 30).

Children’s well being

Some customers ponder whether sure synthetic meals components, equivalent to meals colorings, result in hyperactivity, attention deficit hyperactivity disorder (ADHD), or autism spectrum dysfunction (ASD) in kids.

Artificial meals colorings and flavorings are used to reinforce the look and style of many meals merchandise, particularly these catered to kids. Though pure choices exist, synthetic colours and flavors are normally used resulting from their vibrancy and low value.

Though many teams and diets, equivalent to the Feingold diet, declare that synthetic meals components trigger behavioral points or neurodevelopmental problems in kids, little analysis helps this (31, 32, 33, 34).

However, BPA is an endocrine disruptor which will result in developmental points in rising infants. As such, it has been banned in child bottles, sippy cups, and packages containing toddler formulation. Look for merchandise that say “BPA-free” on the label (35).


Most synthetic meals components are secure for adults and kids to devour. Those which have been proven to hurt human well being are banned or strictly regulated by the FDA.
