In my last post, we took a look at sugar and fat consumption. Fat in foods has been vilified in the United States for years, but in reality our bodies need fats to ensure proper function. That said, not all fats are created equal, only some support overall good health and help to fuel workouts. Dietary fats, or the fats that we ingest, are primarily found in foods from plants and animals. The four major types of fats are monounsaturated fats, polyunsaturated fats, saturated fats and trans fats. Take a look below for an explanation and examples of each!
Monounsaturated fats
Monounsaturated fats are found in a variety of foods and oils. Studies show that eating foods rich in monounsaturated fatty acids improves blood cholesterol levels, which can decrease your risk of heart disease. Research also shows that these fatty acids may benefit insulin levels and blood sugar control.
- Examples:
- Avocados, olives, vegetable oils and nuts (almonds, peanuts, macadamia nuts, hazelnuts, pecans, cashews)
- Are these good or bad fats?
- Good – eat up (but don’t go too crazy)!
Polyunsaturated fats
This is a type of fat found mostly in plant-based foods and oils. Evidence shows that eating foods rich in polyunsaturated fatty acids (Omega-3) improves blood cholesterol levels, which can decrease your risk of heart disease. These fatty acids may also help decrease the risk of type 2 diabetes.
- Examples:
- Walnuts, flax seeds, fatty fish (salmon, tuna, etc.,)
- Are these good fats?
- Yes!
Saturated fats
Most saturated fats are found in animal sources of food, such as red meat, poultry and full-fat dairy products. Saturated fat can raise total blood cholesterol levels and low-density lipoprotein (LDL) cholesterol levels, which can increase your risk of cardiovascular disease and Type 2 diabetes.
- Examples:
- Cheeses, meats, butter
- Are these good or bad fats?
- Debatable – consume in moderation!
Trans fats
Trans fat occurs naturally in some foods in small amounts, but most trans fats are chemically engineered in a food processing method called partial hydrogenation. These partially hydrogenated trans fats can increase unhealthy LDL cholesterol and lower healthy high-density lipoprotein (HDL) cholesterol and increase your risk of cardiovascular disease.
- Examples:
- Commercially-baked goods, margarines, vegetable shortening, fried foods and anything that reads “partially hydrogenated”
- Are these good or bad fats?
- Bad
Healthier fats are found in the form of monounsaturated or polyunsaturated fats – eating foods rich in these fats can improve blood cholesterol levels and lower your risk of heart disease. Do your best to avoid over-consuming saturated and trans fats—over time, they can raise total and LDL (“ bad”) cholesterol, which can increase risk of heart disease and also contribute to increasing your risk of obesity, diabetes, and cancer.
Here’s a graphic of healthy fats to incorporate into your diet from the American Heart Association. They recommend to include good fats in your diet, limit saturated fats and keep trans fats as low as possible. Until next time, happy eating!
