Fat is a crucial macronutrient, but understanding which foods are high in fat and the types of fats they contain is essential for maintaining a balanced and healthy diet. This guide explores foods high in fat, differentiating between saturated and unsaturated fats, and provides practical advice on making informed food choices.
Why We Need Fat
While often demonized, fat plays a vital role in our health. It’s a source of essential fatty acids, which our bodies can’t produce. Fat also aids in the absorption of fat-soluble vitamins like A, D, and E. Furthermore, it provides energy; one gram of fat yields 9kcal (37kJ), more than double that of carbohydrates or protein (4kcal/17kJ per gram). Excess fat, carbs, and protein are stored as body fat. The primary types of fat in our diet are saturated and unsaturated fats, each with different effects on our health.
Saturated Fats: Know Your Sources
Saturated fats are prevalent in both sweet and savory foods, primarily from animal sources, but also found in some plant-based products.
Common Foods High in Saturated Fat
- Fatty Cuts of Meat: Ribs, steak, and ground beef can contain significant amounts of saturated fat.

- Processed Meats: Sausages, bacon, and pies often contain high levels of saturated fat.
- Dairy Products: Butter, ghee, lard, cheese (especially hard varieties like cheddar), cream, sour cream, and ice cream are significant sources.
- Savory Snacks: Cheese crackers and some popcorns can be surprisingly high in saturated fat.
- Chocolate Confectionery: Many chocolate products are high in saturated fat due to cocoa butter.
- Baked Goods: Biscuits, cakes, and pastries often contain butter or other saturated fats.
- Tropical Oils: Palm oil, coconut oil, and coconut cream are plant-based sources high in saturated fat.
The Impact of Saturated Fat on Cholesterol
Cholesterol, a fatty substance produced by the liver, is transported in the blood via low-density lipoprotein (LDL) and high-density lipoprotein (HDL). Consuming too much saturated fat can elevate LDL cholesterol, increasing the risk of heart disease and stroke. HDL cholesterol, conversely, helps remove cholesterol from the body, transporting it to the liver for disposal.
Saturated Fat Guidelines
Health guidelines generally recommend limiting saturated fat intake. In the UK, adults should aim for no more than 30g (men) or 20g (women) of saturated fat daily, with children consuming even less.
Trans Fats: Minimizing Your Intake
Trans fats occur naturally in small amounts in some meats and dairy. They can also be found in partially hydrogenated vegetable oil, which must be listed on food labels. Similar to saturated fats, trans fats can increase cholesterol levels. Current guidelines advise adults to consume no more than 5g of trans fats per day. Many supermarkets have eliminated partially hydrogenated vegetable oil from their own-brand products. Focus on reducing saturated fat as a priority.
Unsaturated Fats: The Healthier Choice
Replacing saturated fats with unsaturated fats is beneficial for heart health and cholesterol levels. Unsaturated fats are primarily found in plant and fish oils, and are categorized as monounsaturated or polyunsaturated.
Monounsaturated Fats: Benefits for Heart Health
Monounsaturated fats help protect the heart by maintaining HDL (“good”) cholesterol levels while reducing LDL (“bad”) cholesterol levels.
Good sources include:
- Olive oil, rapeseed oil, and spreads made from these oils

- Certain nuts, such as almonds, Brazils, and peanuts
Polyunsaturated Fats: Omega-3 and Omega-6
Polyunsaturated fats can also lower LDL cholesterol. The two primary types are omega-3 and omega-6 fatty acids. Because the body cannot produce certain omega-3 and omega-6 fats, it’s essential to include them in your diet.
Omega-6 fats are found in vegetable oils like:
- Rapeseed oil
- Corn oil
- Sunflower oil
Nuts rich in omega-6 include:
- Walnuts
- Almonds
- Cashews
Omega-3 fats are found in oily fish, such as:
- Kippers
- Herring
- Trout
- Sardines
- Salmon
- Mackerel
Aim to consume at least two portions of fish weekly, including one portion of oily fish. Vegetarian sources of omega-3 fatty acids include flaxseed (linseed) oil, rapeseed oil, walnuts, and omega-3 enriched eggs.
Buying Lower Fat Foods: Reading Labels
Food labels are crucial for making informed choices. They provide information on total fat and saturated fat content.
Understanding Fat Content on Labels
- Total Fat:
- High fat: More than 17.5g of fat per 100g
- Low fat: 3g of fat or less per 100g (or 1.5g per 100ml for liquids)
- Fat-free: 0.5g of fat or less per 100g or 100ml
- Saturated Fat:
- High in saturated fat: More than 5g of saturates per 100g
- Low in saturated fat: 1.5g of saturates or less per 100g (or 0.75g per 100ml for liquids)
- Saturated fat-free: 0.1g of saturates per 100g or 100ml
Decoding “Lower Fat” Labels
Products labeled “lower fat,” “reduced fat,” “lite,” or “light” must contain at least 30% less fat than similar products. However, even “lower fat” versions of typically high-fat foods may still be high in fat. Also, lower-fat foods are not always lower in calories, as sugar is sometimes used to replace fat. Always check the nutrition label for accurate information.
Conclusion
Understanding “What Foods Are High In Fat” is the first step towards a healthier diet. By prioritizing unsaturated fats over saturated and trans fats, reading food labels carefully, and making informed choices, you can reduce your risk of heart disease and improve your overall well-being. Remember that a balanced diet involves more than just fat intake; it’s about making nutritious choices across all food groups.
