2.10. Sugar-Added Fruit Juice: More Sugar Than Fruit
Many store-bought fruit juices contain more added sugar than actual fruit. Simply Cranberry Cocktail, for example, contains 29 grams of added sugar per serving and is only 27% cranberry juice. According to the Journal of Clinical Investigation, the sweetness in juice comes from fructose, which is associated with visceral fat.
A Healthier Choice: Stick to 100% juice and avoid products with “cocktail” in the name to cut out added sugars.
2.11. Sugary Cereal: A Breakfast Bomb of Sugar
Sugary cereals can wreak havoc on the body, leading to obesity, diabetes, and heart disease. Fruity Pebbles have 12 grams of added sugar per cup, while Golden Crisps have 21 grams of added sugar, with no fiber to balance the sugar rush.
A Healthier Choice: Look for cereals with less added sugar, and more fiber and protein, such as Purely Elizabeth’s Vanilla Blueberry cereal.
2.12. Cake Frosting: A Chemical Concoction

A Healthier Choice: Use Grade A Medium Amber Pure Maple Syrup, which contains natural antioxidants.
2.14. Bottled Smoothies: Fiber-less and Sugar-Rich
Store-bought smoothies often fall short on nutrition and are filled with calories and sugar. Naked’s Strawberry Banana Smoothie contains 44 grams of sugar and zero fiber.
A Healthier Choice: Blend a homemade smoothie with fruits, vegetables, and protein powder for a fiber-rich, protein-heavy beverage.
2.15. Restaurant Desserts: Oversized and Overloaded

A Healthier Choice: Choose a small scoop of sorbet or vanilla ice cream to satisfy your sweet tooth.
2.16. Added Sugar: A Dangerous Addition to Your Diet
Americans consume about 77 grams of sugar per day, far exceeding the recommended intake. High consumption of refined sugar is linked to type 2 diabetes, heart disease, and obesity.
A Healthier Choice: Use zero-calorie sweeteners or natural sweeteners like honey in moderation. Allulose is a rare sugar that doesn’t spike blood sugars.
2.17. Bottled Coffee: More Sugar Than Coffee
Bottled coffee beverages can be loaded with added sugars. Gold Peak Almond Toffee Coffee Drink contains 53 grams of sugar, far exceeding the caffeine benefits.
A Healthier Choice: Opt for cold brew coffee and add your own creamer and sweetener to control the sugar content.
2.18. Maraschino Cherries: A Sweet and Unnatural Treat
Maraschino cherries are engineered foods containing preservatives, corn syrup, and dyes. These cherries are more of a chemical concoction than a natural fruit.
A Healthier Choice: Eat fresh cherries, which are a good source of resveratrol and other beneficial nutrients.
2.19. Fruit-on-the-Bottom Yogurt: More Sugar Than Fruit
Fruit-flavored yogurts often contain little actual fruit, relying on sugar and fruit juice concentrate. These yogurts are often loaded with sugar and very little protein.
A Healthier Choice: Opt for plain, unsweetened yogurt, Greek yogurt, or Icelandic yogurts that are low in sugar and higher in protein.
2.20. Bottled Salad Dressing: A Sugar and Fat Overload
Many store-bought salad dressings are high in sugar. Stonewall Balsamic Fig Dressing contains 11 grams of sugar, while Marie’s Creamy Italian Garlic contains 19 grams of fat, primarily from inflammatory soybean oil.
A Healthier Choice: Make your salad dressing at home using olive oil, balsamic vinegar, lemon juice, honey, and mustard.
2.21. Fruit Cocktail: A Syrup-Soaked Sugar Bomb
With added sugar on top of natural sugars, fruit cocktail is often worse than consuming fresh fruit on its own. These canned fruits are devoid of nutrients but high in sugar.
A Healthier Choice: Eat whole fruit that’s fresh or frozen whenever possible.
2.22. Certain Protein Bars: Packed with Sugar and Additives
The combination of sugar, carcinogenic colors, and other additives makes most protein bars less of a healthy snack. The Gatorade Recover Peanut Butter Whey Protein Bar has 24 grams of added sugar, which is exactly the daily recommended intake for women.
A Healthier Choice: Opt for a handful of raw almonds, a piece of cheese, or a hard-boiled egg for a healthier post-workout recovery.
2.23. Instant Oatmeal Cups: Convenient but Loaded with Sugar
Even seemingly healthy options like McCann’s Steel Cut Irish Oatmeal Vanilla Honey pack 17 grams of added sugar into one serving. It’s best to avoid these as a breakfast staple.
A Healthier Choice: Start your morning off right by opting for unflavored oats and adding healthy, filling ingredients like raw almonds and fruit.
2.24. Sugar-Free Jam: Artificial Sweeteners and False Promises
Although it could help regulate your blood sugar, Polaner’s Sugar-Free Jam shouldn’t be your go-to source for fiber. It’s sweetened with sucralose, which may impact insulin resistance.
A Healthier Choice: Your safest bet is to top your peanut butter sandwiches with fresh pieces of fruit like bananas and strawberries. You’ll get a similar taste with none of the artificial sweeteners.
3. Processed Meats and Their Risks
Processed meats often contain high levels of sodium and harmful additives, making them some of what are the most unhealthy foods to consume regularly.
3.1. Processed Red Meat: A Recipe for Health Issues

A Healthier Choice: Choose Impossible Sausage, a meat-free sausage option free from questionable ingredients.
3.2. Corn Dogs: Preservatives and Unhealthy Fats
Corn dogs contain preservatives like sodium phosphate and sodium nitrite, which are potentially harmful additives found in processed meats. Foster Farms corn dogs, for example, contain these additives.
A Healthier Choice: Enjoy corn dogs in moderation, or find healthier, more natural brands at the grocery store.
3.3. Bacon: A Breakfast Favorite with Hidden Dangers
Bacon is often preserved with artificial ingredients like sodium nitrite and nitrates, as well as sodium phosphate. These preservatives have been linked to various health issues, including accelerated aging, vascular damage, and cancer, according to research published in Dtsch Arztebl Int and European Journal of Public Health.
A Healthier Choice: Look for “uncured” bacon, which hasn’t undergone a preservation process using synthetic nitrates or nitrites.
3.4. Breakfast Sausage: Sodium and Saturated Fat Overload
Many breakfast sausage brands contain large amounts of sodium and saturated fat, and some contain additives that have been linked to potential health risks. Jimmy Dean Maple Pork Sausage Links contain 9 grams of saturated fat and almost 500 milligrams of sodium per serving.
A Healthier Choice: Choose Applegate Naturals Chicken and Maple Breakfast Sausage, free from synthetic nitrates and nitrites and made with humanely raised chicken.
3.5. Sausage: High in Saturated Fats and Additives
Sausage is typically made from red meat, which is high in saturated fats, and contains high levels of sodium and additives like nitrates and nitrites. These additives can turn into carcinogenic nitrosamines when exposed to high heat, according to the journal Meat Science.

A Healthier Choice: The AICR recommends avoiding processed meats as much as possible and suggests focusing on fresh poultry, as well as nut butter or hummus that you can throw on a couple of slices of bread.
3.7. Hot Dogs: A Processed Meat Nightmare
Hot dogs are high in sodium and carcinogen-producing nitrites. They are also preserved with sodium phosphates, a food additive linked to potential health consequences like cardiovascular disease and chronic kidney disease.
A Healthier Choice: Opt for an organic, uncured option like Applegate Farms’ Great Organic Uncured Beef Hot Dog.
4. Fried Foods and Their Inflammatory Effects
Fried foods are often cooked at high temperatures in unhealthy oils, leading to the formation of harmful compounds. These are definitely what are the most unhealthy foods for your heart.
4.1. Fried Foods: High Heat, Inflammatory Oil
Fried foods contain high levels of inflammatory Advanced Glycation End products (AGEs). According to a 2015 review published in the journal Advances in Nutrition, AGEs can lead to inflammation and oxidative stress in the body, increasing the risk of disease.
A Healthier Choice: Bake or air fry your food instead of frying it in oil.
4.2. Fast-Food French Fries: A Triple Threat of Sodium, Fat, and Calories
Adding a side of fries to your fast-food meal piles on the sodium, fat, and empty calories. Arby’s famous curly fries have over 1,250 milligrams of sodium, while Popeye’s fries have 590 milligrams.
A Healthier Choice: Choose the fries from Chick-fil-A, which have only 240 milligrams of sodium per serving, or opt for a healthier frozen option at home.
4.3. Onion Rings: A Deep-Fried Calorie Bomb
Onion rings are often worse than fries because they tend to have more calories, saturated fat, and total fat. Sonic Onion Rings have 580 calories, 29 grams of fat, 5 grams of saturated fat, and 570 milligrams of sodium.
A Healthier Choice: Order grilled calamari, a house salad, or some chips and salsa instead.
4.4. Fish and Chips: Deep-Fried and Unbalanced
A coating of crispy batter and a pile of deep-fried potatoes is just loaded with sodium and fat, detracting from the health benefits of the fish. The fat and sodium levels make it one of what are the most unhealthy foods.
A Healthier Choice: Abandon fried fish and opt for grilled fish instead.
4.5. Mozzarella Sticks: A Fried Cheese Delicacy
Although there is some protein in mozzarella sticks, this popular appetizer choice is often fried, increasing the calories, sodium, and saturated fat. Applebee’s mozzarella sticks have 18 grams of saturated fat and 2,450 milligrams of sodium.
A Healthier Choice: Munch on pure cheese sticks paired with grapes or almonds, or try an appetizer like bone-in wings or a house salad.
5. Fast Food and Its Health Implications
Fast food is convenient and delicious but often contains high levels of unhealthy fats, sodium, and added sugars. These often top the list of what are the most unhealthy foods because of their accessibility.
5.1. Fast-Food Chicken Sandwiches: High in Fat and Sodium
Continuous consumption of fast food can lead to heart disease, cancers, and even premature death. Fast-food chicken sandwiches are full of ultra-processed ingredients and dangerously high levels of total fat and sodium.
A Healthier Choice: Look for healthier, dietitian-recommended options for fast-food chicken sandwiches.
5.2. Fast-Food Smoothies: Sugar-Packed and Fiber-Poor
Smoothie chains often pack their smoothies full of added sugar with very little protein or fiber. Jamba Juice’s Peanut Butter Mood Smoothie has 102 grams of sugar, while Smoothie King’s The Hulk Strawberry has 91 grams of added sugar.
A Healthier Choice: Make your smoothies at home with veggies, fruit, protein powder, nut butter, and your favorite milk.
5.3. Fast-Food Desserts: Loaded with Excess Sugar and Fat
Fast-food desserts are loaded with excess added sugars, sodium, or saturated fat. McDonald’s Apple Pie or McFlurry, Burger King’s shakes and Sundae Pie, and Taco Bell’s Cinnabon Delights are all high in these unhealthy components.
A Healthier Choice: Order a Wendy’s Frosty in a junior size or a McDonald’s Vanilla Soft Serve Cone.
5.4. Fast-Food Breakfasts: High in Calories and Unhealthy Fats
Fast-food breakfasts are usually high in calories, sodium, and saturated fat, and low in fiber and protein. The Sausage, Egg & Swiss Croissant from Wendy’s has 16 grams of saturated fat and over 1,000 milligrams of sodium, but zero grams of fiber.
A Healthier Choice: Look for lighter options like a McDonald’s Egg McMuffin, a Chick-fil-A Egg White Grill, or Starbucks Egg Bites.
5.5. Fast-Food Burgers: A Culprit of Unhealthy Fats
Fast-food hamburgers and cheeseburgers are some of the worst culprits because of their extremely high fat and saturated fat counts.
A Healthier Choice: Try one of these low-sodium fast-food orders or one of these fast-food meals under 500 calories.
6. Other Foods to Watch Out For
Beyond the usual suspects, some other foods can be surprisingly unhealthy due to their ingredients and preparation methods.
6.1. Bread Bowls: An Overload of Refined Carbohydrates
Bread bowls are extremely high in carbohydrates and contain very little fiber, leading to blood sugar spikes. Panera’s Homestyle Chicken Noodle Soup Bread Bowl contains almost 150 grams of carbohydrates and only 4 grams of fiber.
A Healthier Choice: Order your soup in a traditional bowl and get a piece of bread as your side to satisfy carb cravings.
6.2. Delivery Pizza: High in Saturated Fat and Sodium
Delivery pizza is convenient but often higher in saturated fat, sodium, and calories than homemade options. Pizza Hut’s Pepperoni Pizza has almost 600 milligrams of sodium per slice, while their Stuffed Crust Meat Lover’s Pizza has 940 milligrams of sodium and 10 grams of saturated fat per slice.
A Healthier Choice: Try one of these “healthier” fast-food pizza pies.
6.3. Microwave Popcorn: Hidden Sodium and Palm Oil
Many microwave popcorn brands are full of sodium and palm oil, which has been linked to increased risks of heart disease, as noted in PLoS One. Act II also makes a Hot & Spicy microwave popcorn that contains the artificial dye Red 40, linked to behavioral changes in children.
A Healthier Choice: Skip the microwaving altogether and grab a bag of pre-popped Lesser Evil Himalayan Pink Salt Organic Popcorn.
6.4. Bottled Ketchup: Added Sugars and Sodium
Many store-bought ketchups use added sugars and higher levels of sodium. Heinz Tomato Ketchup comes with 4 grams of added sugar and 180 milligrams of sodium per tablespoon.
A Healthier Choice: Primal Kitchen Ketchup is free from any added sugars and made with quality ingredients like organic balsamic vinegar and organic garlic powder.
6.5. Alcohol: Moderation is Key
While some studies support drinks like red wine as heart-healthy because of their high antioxidant levels, excessive alcohol consumption is linked to inflammation, liver disease, and cancer.
A Healthier Choice: Mingle Mocktails are ready-to-drink mocktails that satisfy a desire to sip on something fun for cocktail hour, sans booze.
6.6. Cocktail Mixes: A Sugar Overload in a Glass
Many cocktail mixes are high in added sugars. Jose Cuervo Classic Margarita Mix comes with 24 grams of added sugar, while Master of Mixes Strawberry Daiquiri/Margarita Mix has 46 grams of added sugar per serving.
A Healthier Choice: Combine lime, orange juice, and agave with your tequila for a DIY margarita that is far lower in added sugars.
6.7. White Flour Bread: Bleaching Chemicals and Low Fiber
If the ingredients label on your loaf of bread mentions bleached flour, you’re likely consuming undesirable chemicals. Some manufacturers use azodicarbonamide, a plastic dough conditioner that breaks down into a chemical called urethane during baking, which is considered a carcinogen.
A Healthier Choice: Choose whole-grain and whole-wheat breads that don’t include bleaching chemicals and provide more fiber.
6.8. Charred Meats: Cancer-Causing Compounds
When you char meat, heterocyclic amines (HCAs) develop, increasing the risk of certain cancers, including pancreatic cancer, according to research in Genes Environ.
A Healthier Choice: Add antioxidant-rich spice extracts, like rosemary, to beef patties or marinate it in wine or beer to help reduce HCAs in your grilling process.
6.9. Energy Drinks: A Dangerous Caffeine and Sugar Cocktail
Energy drinks are simply overpriced chemical cocktails with high caffeine and sugar. A University of Maryland study found energy drinks to be 11 percent more corrosive to your teeth than regular soda, and overconsumption can destroy your liver, as reported in BMJ Case Reports.
A Healthier Choice: Choose green tea, which is all-natural and a great energy booster.
6.10. Ready-to-Bake Pie Crust: Preservatives to Avoid
