Food Additives You Should & Shouldn't Avoid Nutrition experts give the 411 on which food additives are best to dodge and which are fine to eat.

There is so much fearmongering about what is in processed foods, especially when it comes to food additives that, as WHO explains, are incorporated “to maintain or improve its safety, freshness, taste, texture, or appearance.” While a diet excluding all processed foods or one that allows for food items with minimally processed ingredients certainly represents a healthy ideal, the additive component of processed foods isn’t always the driving factor behind why it’s perhaps considered harmful to your health. To get a better sense of some common food additives, including how they actually affect your diet and overall health, we consulted a few nutrition experts for their insight.

As the FDA notes, “any substance that is intentionally added to food” is considered a food additive. Furthermore, the FDA has a strict screening process to evaluate food additives, which determines whether or not the additive in question is potentially toxic or generally recognized as safe (GRAS). In fact, there are a number of food additives that are banned because they are regarded as illegal substances, and the FDA tightly regulates this.

So while having a healthy curiosity about what food additives really are and how they may potentially impact your body is completely natural and understandable, you don’t need to consume yourself by obsessively splitting hairs over them. If your aim is to do better for your body, it’s more important to place greater emphasis on eating nutrient-dense foods while carefully regulating the amount of ultra-processed foods you eat, if not avoiding them completely.

Food Additives to Avoid

Because the occasional splurge with a processed treat or consuming foods containing processed ingredients is bound to happen sooner or later, you should be aware that like most things, some additives may serve you and your health better than others. Are there any food additives you should absolutely avoid, and which food additives perhaps seem bad for you but really have a bark that’s worse than its bite?

Here’s what these nutrition experts had to say about exactly which food additives you should—and shouldn’t—worry about. And for more useful healthy eating advice, be sure to also check out 10 Dietitian-Backed Food Trends You Should Try in 2023.

While the FDA has qualified and labeled all food dyes as GRAS, some research acknowledges that there may be a connection between red dye and hyperactivity and aggression in kids. However, more evidence is needed to support a conclusive statement.

Additives That Seem Scary—but Are Actually Safe

“Although more research is needed at this time, it may be worth trying to avoid red dye 40—a synthetic food dye made from petroleum—in children with ADHD,” says Megan Warnke, RDN. While health organizations have concluded red dye 40 poses little health risk, some studies have found its consumption may lead to mild allergic skin reactions and worsen behavioral symptoms in children with ADHD.”

Although many nitrates we consume come from plants, there is growing evidence that nitrates and nitrites added to processed meat are linked to certain cancers, particularly those that can impact your stomach and colon.

“I recommend avoiding nitrates and nitrites found in packaged meats like bacon and lunch meat,” advises KeyVion Miller, RDN, LDN, a dietitian and culinary nutritionist. “These additives have been shown to possibly contribute to an increased risk of colon cancer.”

Although more research in humans is needed before we can make conclusive claims about the potential dangers and health risks associated with this food additive, there does seem to be some evidence to suggest that maltodextrin can disrupt a healthy gut.

“Maltodextrin is added to foods to improve texture, flavor, and shelf-life,” says Kim Kulp, RD, a registered dietitian at the Gut Health Connection. “While generally considered safe, one [2018] study in mice shows it may increase the number of harmful microbes in the gut, and damage the lining of the intestines. These changes may lead to an increased risk of inflammatory bowel disease.”

While putting gum in food may sound concerning, guar gum is an additive you don’t have to fear. In fact, guar gum is a type of fiber that has a functional purpose in our food supply as well as some potential health benefits.

“Guar gum is a long-chain carbohydrate used by the food industry to thicken and bind foods such as ice cream, soups, and sauces,” explains Dr. Vishnumohan. “Guar gum is safe in moderation for most people, and sourced from a legume called guar beans. It is high in fiber and has been associated with better digestive health as well as increased feelings of fullness.”
