Hydrogenated fats, commonly known as trans fats, are a type of dietary fat that can pose significant health risks when consumed in excess. These fats are primarily created through an industrial process called hydrogenation, where hydrogen is added to vegetable oils to solidify them. This process extends shelf life and changes the texture of foods, making them appealing to food manufacturers. However, regularly eating foods high in hydrogenated fats can elevate your risk of heart disease and other serious health conditions.

While some trans fats occur naturally in certain animal products in small amounts, the majority of hydrogenated fats in our diets come from partially hydrogenated oils (PHOs) added to processed foods. These PHOs were once widely used in fried foods, baked goods, and shortening. Understanding which foods commonly contain these harmful fats is crucial for making healthier dietary choices and protecting your cardiovascular health.
Research has consistently demonstrated the detrimental effects of hydrogenated fats on health. They are linked to several negative outcomes, including promoting inflammation throughout the body, increasing levels of LDL (“bad”) cholesterol while decreasing HDL (“good”) cholesterol, and contributing to the development of atherosclerosis, the dangerous buildup of plaque in arteries. These factors significantly elevate the risk of heart disease, a leading cause of death. Health organizations and the FDA have strongly recommended minimizing or eliminating hydrogenated fats and PHOs from our diets to mitigate these risks.
Although regulations and health awareness have led to a reduction in the use of PHOs by food manufacturers and restaurants, hydrogenated fats can still be found in a variety of foods. Being informed about these sources empowers you to make better choices for your well-being. To reduce your risk of heart disease, it’s important to be mindful of the following food categories and check labels carefully.
1. Fried and Battered Foods
Many restaurants, particularly fast food establishments, historically used and some may still use PHOs for frying and battering foods. This is because hydrogenated oils are often less expensive and can enhance the taste and crispy texture of fried items like french fries, fried chicken, and onion rings. While many establishments have transitioned away from PHOs, it’s still wise to inquire about the type of oil used, especially in smaller or local restaurants, or check for trans fat content on nutritional information if available.
2. Baked Goods
A wide array of commercially produced baked goods can be sources of hydrogenated fats. These include items like biscuits, breads, cakes, cupcakes, muffins, cookies, brownies, pies, and sweet rolls such as cinnamon rolls. The PHOs in these products contribute to texture and shelf stability. Checking the ingredient lists for “partially hydrogenated oil” is crucial when purchasing these items.
3. Baking Ingredients
Beyond finished baked goods, certain baking ingredients themselves can contain hydrogenated fats. Common culprits include cake mixes, frosting, margarine sticks, pie crusts (especially pre-made), and shortening. These ingredients are often used to achieve specific textures and consistencies in home baking and commercially prepared products. Opting for alternatives like butter or oils in moderation and reading labels for hydrogenated oils in pre-made ingredients can help reduce your intake.
4. Breakfast Foods
Certain breakfast foods can also harbor hydrogenated fats. Pancake and waffle mixes, while many now are PHO-free, should still be checked for partially hydrogenated oils in their ingredient lists. Breakfast sandwiches, especially those served on biscuits from fast-food restaurants, can be surprisingly high in trans fats due to the use of PHOs in the biscuit or fillings. Frozen breakfast sandwiches may also contain small amounts of trans fat.
5. Frozen Foods
Frozen foods are often formulated to include hydrogenated fats to improve stability during freezing and thawing, as well as to create a more palatable, fatty mouthfeel. While not all frozen foods are problematic – frozen fruits and vegetables are healthy options – some processed frozen meals, pizzas, and even certain ice cream flavors can contain trans fats. Always review ingredient lists for PHOs, even in seemingly healthy frozen food categories.
6. Meat Products
While some trans fats occur naturally in beef, processed meat products can also contain hydrogenated fats added during manufacturing. Examples include beef sausages, canned or frozen beef chili, frozen burgers, ground beef (in some processed forms), hot dogs, and meat sticks. These added fats contribute to texture and preservation. Choosing leaner cuts of meat and limiting processed meat intake is generally recommended for a heart-healthy diet.
7. Non-Dairy Creamers
Non-dairy coffee creamers, often used as a dairy alternative, can be a hidden source of hydrogenated fats. Even if the nutrition label states “0g trans fat per serving” due to rounding rules, partially hydrogenated oils may still be listed as a primary ingredient. If you are a regular coffee drinker using non-dairy creamer multiple times a day, these small amounts of trans fat can accumulate. Consider alternatives like milk, almond milk, or soy milk, or choose creamers that explicitly state they are trans fat-free and check the ingredient list to confirm the absence of PHOs.
8. Snacks
Certain snack foods can also contain hydrogenated fats. Some crackers, even those not listing trans fat on the nutrition label, may contain partially hydrogenated cottonseed oil or other PHOs. Microwave popcorn, including some organic brands, can also be a source of trans fats. While popcorn itself can be a healthy whole-grain snack, it’s important to choose varieties without added hydrogenated oils and limit unhealthy toppings.
To effectively avoid hydrogenated fats, diligently check Nutrition Facts labels and ingredient lists on packaged foods. Look for the words “partially hydrogenated oil” in the ingredient list, as this indicates the presence of trans fats. Be aware that food companies are allowed to list “0g trans fat” if a serving contains less than 0.5 grams, so checking ingredients is crucial. When dining out, especially at smaller establishments, don’t hesitate to ask about the type of oils used for frying or cooking. Making informed choices and prioritizing whole, unprocessed foods are key strategies for minimizing your consumption of unhealthy hydrogenated fats and promoting better heart health.
