Good Fats Vs Bad Fats
Not all fats are created equal. Some fats are better for you than others and may even help to promote good health. Knowing the difference can help you determine which fats to avoid and which to eat in moderation.
Dietary fat, also known as fatty acids, can be found in foods from both plants and animals. Certain fats have been linked to negative effects on heart health, but others have been found to offer significant health benefits. Certain bodily functions also rely on the presence of fat. For example, some vitamins require fat in order to dissolve into your bloodstream and provide nutrients.
What are the less healthy fats?
Two types of fats — saturated fat and trans fat — have been identified as potentially harmful to your health. Most of the foods that contain these types of fats are solid at room temperature, such as:
butter
margarine
shortening
beef or pork fat
Saturated fat: Use sparingly
Most saturated fats are animal fats. They’re found in high fat meats and dairy products.
Saturated fat sources include:
fatty cuts of beef, pork, and lamb
dark chicken meat and poultry skin
high fat dairy foods (whole milk, butter, cheese, sour cream, ice cream)
tropical oils (coconut oil, palm oil, cocoa butter)
lard
Traditionally, doctors have linked higher saturated fat intake with increased heart disease risks. This idea has been called into question more recently.
According to Harvard University, researchers now think saturated fat may not be as bad as once thought — but it still isn’t the best choice for fats. The researchers concluded that replacing saturated fat in your diet with polyunsaturated fats can reduce your heart disease risk.
A 2017 journal article published in the British Journal of Sports Medicine reported that the risks of LDL (bad) cholesterol had previously been overstated, particularly when it comes to a negative effect on heart health.
