Fats: The Good, The Bad and The Ugly
Nutritionists often talk in terms of "good" fats, such as monounsaturated and polyunsaturated fats, and "bad" fats, like saturated and trans fats. Here's a summary of the different categories of fats, broken down into the good, the bad and the downright ugly.
The Good
Monounsaturated Fat:- A "good" fat
- Reduces overall cholesterol levels, and specifically LDL or "bad" cholesterol, while increasing levels of HDL or "good" cholesterol
- Found in nuts and seeds, avocados, olive oil and canola oil
- Another "good" fat
- Reduces overall cholesterol levels, and specifically LDL or "bad" cholesterol
- Found in fatty fish such as salmon, mackerel, trout and sardines, and also in corn, safflower, sunflower and soybean oils
The Bad
Saturated Fat:- A "bad" fat
- Increases overall cholesterol levels, specifically LDL or "bad" cholesterol
- Found in animal-based foods such as meat, poultry and eggs, and also in butter, cream and other dairy products
- Also found in plant-based products such as coconut, so-called "tropical oils" like coconut oil, palm oil and palm kernel oil, and cocoa butter
The Ugly
Trans Fat:- Another "bad" fat
- Increases levels of LDL or "bad" cholesterol and lowers levels of HDL or "good" cholesterol
- Found in hydrogenated fat products such as margarines and vegetable shortenings
- Used in packaged snack foods such as cookies, crackers and chips, and in fried foods from fast-food and other restaurants
The following table shows, in grams, how much saturated, monounsaturated, polyunsaturated and trans fats are contained in 1 tablespoon of various commonly used oils and fats.
