Saturated fats, unsaturated fats, trans fats…what do all these mean? These are the different types of fats found in foods that we eat. The difference is in their chemical structure, deeming some “healthy” and others “unhealthy.”
“Unhealthy” Fats: Saturated & Trans Fats – excess intake of these fats are linked with increased rates of disease, such as heart disease. These fats are mostly solid at room temperature.
- Saturated fats – These fats contain all single bonds and are saturated with hydrogen. Some major sources of saturated fats come from meats, poultry with skin, butter, lard, whole milk dairy products, coconut oil, and palm oil. These fats increase LDL (“bad”) cholesterol.
- Trans fats – These fats have been partially hydrogenated (look for those words on a food label to identify them) to increase shelf stability and saturation; the name trans fat comes from the position of the hydrogens and the double bond. Major sources include baked goods, fried foods, margarines, and processed foods. These fats both increase LDL (“bad”) cholesterol and decrease HDL (“good”) cholesterol.
“Healthy” Fats: Unsaturated Fats– Increased intake of these fats are linked with improved cholesterol levels and other various health benefits. These fats are mostly liquid at room temperature.
- Monounsaturated fats – These fats have one double bond present. Major sources include canola oil, olive oil, peanut oil, avocado, and pumpkin seeds.
- Polyunsaturated fats – These fats have two or more double bonds present and include the essential omega-3 fatty acids. Major sources include fish, safflower oil, corn oil, soybean oil, and certain seeds (such as flax & chia).
Is there a “good” time of day to eat fats?
Fats increase your feeling of fullness and satiety because they delay gastric emptying; meaning food stays in your stomach longer. Because of this, it is not a good idea to consume a high-fat meal right before exercise as it may cause an upset stomach, nausea, and cramping.
An important tip to remember is to balance your meals and spread your intake throughout the day. As with any food, moderation of fats is still important. When possible, try to choose the “healthy” fats over the “unhealthy” fats.
How can you increase your intake of healthy fats?
- Choose olive or canola oil based salad dressings instead of creamy dressings. This will also shave a lot of calories off your salads!
- Try snacking on trail mixes with nuts and seeds instead of reaching for a bag of chips or cookies.
- Limit the amount of French fries, ice cream, pastries, fried chicken, and fatty meats
- Try to increase your fish intake to 2x a week. Don’t forget to look for fish items on restaurant menus too!
- Add avocados to your salad or make homemade guacamole. Below is a great and healthy recipe from Central Market. http://www.centralmarket.com/Recipes/RecipeDetail.aspx?rid=81129

Hi! Great article on fats. I think it’s important that people know that not ALL saturated fats are unhealthy. The fat found in coconut is almost all of the saturated kind, but it’s not fair to lump it in with all other saturated fats. The fat found in coconut is a great source of medium chain triglycerides (MCTs) and these are easily digested and actually help your body use fat for energy as opposed to storing it – obviously a great thing!
All hail the coconut!
Keep up the good work!

The difference between saturated and unsaturated fats; Saturated is bad for your health, and when it is left at room temperature it will become solid and waxy.
