15 Foods You Should Always Avoid, According to Experts

Even if you aren’t trying to lose weight, eating the right food – and avoiding the wrong – is a key part of health. Food is linked to everything from heart and brain health to overall longevity. So what food should you avoid at all costs? Here is what the experts say.

Doughnuts

Blanca Garcia, RDN, and nutrition specialist at www.healthcanal.com, recommends avoiding doughnuts. “Although very tasty, doughnuts are sugar on top of sugar; the dough that it’s made of is refined flour, which, when consumed, gets absorbed quickly into the bloodstream, increasing sugar levels. But also, most doughnuts are coated with actual sugar, sugary toppings, and sugary fillings,” she says. “They are also dipped in oil, which increases the fat content. Doughnuts have an excess amount of simple carbohydrates and fat. There is no protein or vitamins and minerals to contribute to health, at no point is doughnut healthy.”

Soda

Blanca also suggests avoiding mainstream soft drinks. “Soda is such a common beverage in homes, restaurants, gatherings, and work gatherings. Regular soda only contributes sugar, no proteins, vitamins or minerals. There is nothing soda can do to contribute to health, it actually displaces the space of foods that do contribute to nutrients,” she says.

Fried Chicken

Chicken is a source of protein, some vitamins and minerals can be healthy if baked, broiled, or grilled, says Blanca. “However, when deep fried with coating, it increases in simple carbohydrates from the coating and is fully engulfed in fat, which significantly increases its fat content besides the already natural fat content found in chicken.”

Nutritionally Empty Foods

Kaytee Hadley, MS, RDN, IFMCP, CPT functional medicine dietitian and founder of Holistic Health and Wellness, stresses the importance of avoiding all nutritionally empty foods. “To lose weight, both nutrients and quality ingredients matter. ‘Nutritionally empty’ foods like chips, baked goods, fried food, and sugary beverages can get in the way of progress because they all contain lots of simple carbohydrates that are high calorie but not very filling, leaving you hungry or improperly fueled,” she says.

Sugary Drinks

“Starting the day with a sugary coffee like Starbucks frappuccinos could be seriously impeding your weight loss goals,” says Hadley, pointing out that one Frappuccino “can easily add 300+ calories to your day without any nutrients to help keep you feeling satisfied, fueled, or even full.”

Fried Foods

Focusing on macronutrients like protein and fat is a common goal for many looking to lose weight, but it’s important to recognize that quality also matters, says Hadley. “Fried chicken, for example, may have high protein content but the fried food can increase levels of inflammation that may actually lead to weight gain. Instead, opt for minimally processed ingredients, gentle cooking methods, and focus on adding colors from fruit and veg to fuel your body at a cellular level.”

Foods with Ingredients You Can’t Pronounce

Mark Hyman, MD, one of the world’s leading physicians and one of Gwyneth Paltrow’s go-to health experts, discussed foods to avoid on episode 818 of his podcast, The Doctors Farmacy. “First of all, if you read something on a label and you don’t know what it is and you can’t pronounce it, don’t eat it,” Hyman instructed, listing Butylated hydroxytoluene, or BHT, as an example as it “is a known carcinogen that’s banned in most countries except the United States.” He adds that food is “not a chemistry project,” so “if you can’t pronounce it, don’t eat it.”

Refined Oils

Refined oils are a no-no, according to Hyman. This includes canola, vegetable, soybean, corn oils, and margarine.

Hydrogenated Fats

Hydrogenated fats are also a big fat no. Hyman explains it “means they’ve chemically altered the fat. It’s a plant oil that is liquid at room temperature and they’ve injected it with hydrogen to bind to the fats, and it’s kind of a chemical thing.” He adds that “there’s no doubt, there’s no controversy, there’s no nutrition scientist, no professional association, no government that says that this is something we should be consuming anymore. It’s just a hard no.”

High Fructose Corn Syrup

Another “hard rule” according to Dr. Hyman is avoiding high fructose corn syrup, because it is “not a whole food” and is “a highly processed industrial food product.” He adds that it has mercury in it and is “basically deconstructed” food. “So in normal sugar, glucose and fructose are bound together. In high fructose corn syrup, they’re not, they’re free, and it’s free fructose,” he says, explaining that it enters your body and causes insulin resistance, inflammation, and elevates uric acid. In order to absorb fructose unlike glucose, “it requires a lot more energy,” he continues, “and so when you’re eating a lot of fructose, it takes a lot of energy in the gut and that actually causes the gut to weaken and leak and become leaky. And then you get these holes in your intestine and that causes food and bacteria to leak in, causing inflammation throughout the body, which leads to heart disease, diabetes, obesity, cancer, Alzheimer’s, you name it, it’s really bad.”

Fast Food

Another “no brainer” according to Hyman? “Don’t go to fast food restaurants.” He explains that a chicken nugget has “27 or 37 ingredients and one of which is chicken. Just don’t eat that food. It’s made in ways that are really bad. In fact, a burger at McDonald’s is actually, I think only 50% beef and in the rest of it’s all this weird filler and stuff that we should be eating.”

Anything with MSG

Hyman says that “you have to be really diligent” about identifying foods that have MSG, or monosodium glutamate. “Now, this is an excitotoxin. This is something that glutamate is an important neurotransmitter that regulates something called NMDA receptors in the brain. And if you overstimulate these, it actually can lead to all kinds of brain issues and cognitive dysfunction,” he explains.

Mostly Everything in Aerosol Cans

While certain spray cans are okay, ”aerosol is just bad for the environment. It’s bad for the ozone layer, and I wouldn’t eat it,” says Hyman.

Artificial Sweeteners

Artificial sweeteners should also be avoided, says Hyman. Not only could they lead to weight gain, but it affects your microbiome, and can create inflammation. “It has a huge effect on your microbiome. It causes fermentation, bloating, distension, and I would really encourage you all just to stay away from the sugar alcohols for that reason,” he says. “I think stevia may be all right, monk fruit may be all right. We’re still trying to figure that out. But I would really stay away from all the other artificial sweeteners.”

Processed Foods

“Processed foods that have added sugars, trans fats, and artificial ingredients should be avoided at all costs. They tend to cause weight gain, swelling/inflammation, and even chronic diseases like diabetes and heart disease,” says Antoni Adamrovich, MSN, BA, APRN, FNP-C; the Chief of Medicine and Co-Founder of tb2.health.

“Try to limit your intake of beverages with high sugar (e.g., soda, artificially sweetened juices, etc.) and high-sodium foods (e.g., processed snacks, fast food, etc.). Pack your diet with nutrient-dense foods (e.g., fruit, vegetables, lean proteins, whole grains, healthy fats, etc.),” he says. “Regularly eating these types of foods will go a long way in supporting your health and well-being. They provide your body with the essential vitamins, minerals, and antioxidants you need, while minimizing the intake of empty calories.”

Do you ever feel like your diet is holding you back from optimal health? You're not alone. Dr. Nick Zyrowski, D.C, B.S., a doctor and clinician, is on a mission to help people transform their health naturally. With his expertise in nutrition and wellness, Dr. Zyrowski shares insights on the foods we should avoid for better health. Joining him are other experts like Dr. Mark Hyman, a pioneering functional medicine physician, and Kaytee Hadley, MS, RDN, IFMCP, CPT, a functional medicine dietitian. Together, these health gurus reveal the top foods that might be sabotaging your well-being. Read on to discover which foods you should eliminate from your diet today — your body will thank you for it!

Ditch the Bleached White Flour and Refined Grains

Dr. Zyrowski warns against consuming bleached white flour and refined grains. "This is a grain that's gone through a process where the nutrient-rich wheat kernel has been removed, and so any vitamins and minerals it may have had to begin with are now gone," he explains in his post. These processed grains are often treated with chemicals like benzoyl peroxide and chlorine. Found in many staple foods like bread, pasta, and crackers, these refined grains are far from being real, nutritious food.

Say Goodbye to Low-Fat Foods

Contrary to popular belief, low-fat foods are not the answer to a healthy diet. Dr. Zyrowski debunks this myth, stating, "The idea that we should eat low-fat foods is probably one of the biggest lies ever pushed on people." He reminds us that our brain is 80% fat, and our body's cells have fatty membranes. Instead of low-fat options, he recommends full-fat alternatives like raw almond butter, plain full-fat yogurt, and whole milk from grass-fed cows.

Avoid Processed Deli Meats

Deli meats often contain hidden ingredients that can be harmful to your health. "Deli meats can be loaded with a lot more ingredients than you ever bargained for," cautions Dr. Zyrowski. These processed meats often contain added sodium, nitrates, artificial flavorings, and even corn syrup. He suggests opting for whole, unprocessed meats instead.

Cut Out Sugary Drinks

Sugary beverages are a major culprit in poor health. Dr. Zyrowski warns, "There's not a better way to create a problem like insulin resistance in your body than drinking these types of beverages." This includes not just sodas but also fruit juices, sweetened teas, and energy drinks. He recommends choosing water, sparkling water, or stevia-sweetened beverages instead.

Eliminate Sugary Foods

Dr. Zyrowski underlines the dangers of sugar, noting that many people may have insulin resistance without realizing it. He advises avoiding foods like cereals, snack bars, candy, sweetened yogurt, and ice cream. "Sugar comes in over 250 names on the food label," he warns, suggesting we look for ingredients ending in "-ose" to identify hidden sugars.

Steer Clear of Fried Foods

Fried foods, including chips, french fries, and fried meats, are best avoided. Dr. Zyrowski explains that these foods create "a lot of inflammatory advanced glycation end products" and oxidative stress in the body, which can lead to various health issues. Kaytee Hadley, MS, RDN, IFMCP, CPT, adds, "Fried chicken, for example, may have high protein content, but the fried food can increase levels of inflammation that may actually lead to weight gain."

Beware of Bad Fats

Shutterstock

While healthy fats are essential, many common fats are harmful. Dr. Zyrowski advises against vegetable oils, canola oil, soybean oil, and margarine. "These fats are all inflammatory, and they lead to inflammatory conditions," he states. Instead, he recommends healthy fats like coconut oil, avocados, butter, nuts, seeds, and olive oil.

Eliminate Fast Foods

Shutterstock

Fast foods, whether from restaurants or pre-packaged meals, are loaded with unhealthy ingredients. Dr. Zyrowski notes that these foods often contain "the sugar, the preservatives, the bad fats" mentioned earlier. Despite their convenience, he strongly advises against consuming fast foods.

Ban Artificial Flavorings, Sugars, and Dyes

Shutterstock

At the top of Dr. Zyrowski's list are artificial additives. "Artificial means not found in nature, made in a lab, a.k.a. fake food," he explains. These additives are often used to keep costs low and profits high, but they're linked to serious health issues, including cancer.

Avoid Foods with Unpronounceable Ingredients

Dr. Mark Hyman, a leading physician, advises, "First of all, if you read something on a label and you don't know what it is and you can't pronounce it, don't eat it." He gives an example: "Butylated hydroxytoluene, or BHT, is a known carcinogen that's banned in most countries except the United States."

Say No to High Fructose Corn Syrup

Dr. Hyman considers high fructose corn syrup a "hard rule" to avoid. He explains, "It's not a whole food and is a highly processed industrial food product." He warns that it can cause insulin resistance and inflammation and elevate uric acid levels.

Limit Artificial Sweeteners

Dr. Hyman also advises against artificial sweeteners. "It has a huge effect on your microbiome. It causes fermentation, bloating, distension," he explains. Dr. Jacqueline Wolfadds, "Avoid sugar alcohols (which end in -ol) such as sorbitol, mannitol, xylitol and erythritol. They cause gas and often bloating because we cannot break them down."

Be Cautious with Carbonated Beverages

Carbonated drinks can contribute to bloating. Beth Czerwony, RD, explains, "Think about what happens if you shake a can of soda. That's what is happening inside of you after you drink it. The bubbles have no place to go — and it will make you feel bloated."

Watch Out for High-Sodium Foods

The Cleveland Clinic warns, "Eating meals that are high in sodium, high in fat or heavy with refined carbohydrates (such as bread, buns or breading) can all leave you feeling bloated."

Take Action: Tips for Success

Dr. Zyrowski offers practical advice for avoiding these unhealthy foods: Don't buy them, remove them from your home, be wary of misleading marketing, and always plan and prep your meals. By following these strategies, you can take control of your diet and improve your overall health.

Antoni Adamrovich, MSN, BA, APRN, FNP-C, advises, "Pack your diet with nutrient-dense foods (e.g., fruit, vegetables, lean proteins, whole grains, healthy fats, etc.). Regularly eating these types of foods will go a long way in supporting your health and well-being."

You've probably seen articles about "foods to avoid" if you're trying to gain muscle or lose weight—including on this website. Some advice is so strict, that these products feel almost banned from any healthy meal plan.

But is that approach too broad and under-researched? "The 'foods to avoid' question is a very nuanced question without the context behind it. As a dietitian, I don't typically advise patients to just avoid foods just because," says Sarah Schlichter, MPH, RDN of Bucket List Tummy. "Offering blanket recommendations of foods to avoid is not helpful for people without considering their budget, access to food, food and cultural preferences, time available for cooking, etc. Therefore, people should avoid foods they don't like, or that they are allergic to. But, in general, nearly all foods can fit in a person's diet/lifestyle, even if it takes some practice and understanding how to make a balanced plate work for them."

With that in mind, we talked to Derek Lipton, MS, RD, CSSD, CSCC, a Registered Dietitian and Sports Nutrition Consultant for Bodybuilding Reviews. He says certain big-name "healthy eating" experts—one in particular—spread misinformation and are fearmongers, but most of what some say isn't backed by science and/or is over-exaggerated. Here are some he says are A-OK in moderation.

Processed Foods Can Be Included in Your Diet Mindfully

"Processed foods are often demonized because they are associated with weight gain and poor health. Processed foods tend to be higher in calories, lower in nutrients, and less filling -- so it's easy to over-consume them and gain weight; however, a balanced diet can easily include these if you're mindful of your calories and make sure to focus on mostly whole foods," says Lipton.

Seed Oils Aren't Inherently Dangerous

"Seed/refined oils are largely demonized due to observational research and animal studies; however, human trials have shown time and time again that there is actually no inherent harm from these oils and are actually BETTER for you than animal fats (PMID: 33127255, PMID: 33762150, PMID: 30809634, PMID: 30006369). The issue is quantity. Seed oils are much cheaper than olive oil or butter, so they get used more -- especially in fried foods and packaged products. So over time, we've seen a correlation between seed oil intake and obesity + other health problems -- but this is due to excess caloric intake and resulting weight gain, not the inherent nature of the oils themselves (as the aforementioned studies demonstrate)," says Lipton.

High Fructose Corn Syrup is Like Sugar, Dangerous When Abused

"The negative image of HFCS is similar to that of seed oils. As HFCS intake increased, so did obesity and related health problems. Once again, it's because HFCS is much cheaper than natural sugar, so companies have been able to use more of it in their products -- resulting in increased calories consumed. In fact, the body cannot tell the difference between sucrose (table sugar) and HFCS -- it's simply just the lower cost of HFCS has enabled higher usage," says Lipton.

Artificial Sweeteners Can Help Reduce Caloric Intake

"Artificial sweeteners are another fun one, because people will cite studies showing the link between these and cancer or impaired gut health -- however, these studies were done in RATS. The dose they used in these studies would be equivalent to drinking over 40 cans of diet soda PER DAY. However, no studies in humans have shown any detrimental impact from using artificial sweeteners. In fact, these artificial sweeteners are great way to reduce caloric intake in those that typically like sweetened beverages," says Lipton.

Final Word From the Expert

"Overall, a lot of demonized foods and fear-mongering comes from misunderstood research or animal studies and is usually blown out of proportion. When looking at human control trials, these foods can all be consumed within moderation and not present any negative on health, as long as you stay within your caloric needs," says Lipton.

Avoid All Simple and Most Complex Carbohydrates, She Recommends

“Disclaimer, this will be challenging and not for everyone,” she warms at the start of the clip. “Avoid all simple carbohydrates and most complex carbohydrates. For now, this includes fruits as they're high in sugar, except for avocados and berries,” she says.

Here Is Why Carbohydrates Are Bad, She Says

“So what can you eat here?” She suggests starting by drinking “plenty of water, avoiding soda, juice, and coffee with cream or sugar.”

She Suggests Eating These 12 Foods

She goes on to list “12 foods with little to no sugar,” starting with greens. “Organic kale with zero grams of sugar. Red meat such as beef, lamb, and organ meats with zero grams of sugar. Wild salmon with zero grams of sugar, chicken with zero grams of sugar, coconut oil, or extra virgin olive oil with zero grams of sugar. Pure butter with 0.1 grams of sugar per a hundred grams sauerkraut with 0.1 grams of sugar per ounce cheese with zero to 0.4 grams of sugar per ounce. Avocados with 0.4 grams of sugar eggs with 0.6 grams of sugar vegetables such as the ones listed above with zero grams of digestible carbs. Lastly, berries with four to 10 grams of sugar per a hundred grams,” she says.

RDN Disagrees and Calls This “Unsustainable”

Cutting Out Added Sugar Is Fine

“Cutting out added sugar is fine and there is no negative to doing it other than just maybe going through some cravings at first,” she continues. “Cutting out all carbs and natural sugar can leave you with very little fiber (constipation and other digestive issues) and also will potentially leave you with very little energy.”
