You’ve probably heard it a hundred times: "Fats are bad for your heart." But is that the whole truth?

Well, it’s not! In fact, the US dietary guidelines recommend that fats make up 20-35% of your daily intake. So, if fats are necessary, why are they often seen as the bad guys? The answer lies in the type of fats you’re consuming.

While some fats can protect your heart and keep you healthy, others can clog your arteries and lead to heart disease. Let’s cut through the confusion and figure out which fats you should welcome onto your plate—and which ones you should leave behind.

What are fats, and why do we need them?

Fats are one of the body's main sources of energy, but they do much more than just fuel us. They help:

  • Absorb vitamins like A, D, E, and K
  • Keep your skin healthy
  • Provide energy
  • Synthesize hormones
  • Support brain function
  • Support cell structure and function

In addition, they play an important role in maintaining healthy cholesterol levels and reducing inflammation. However, the type of fat you consume is more important than the total amount.

Different types of fats

Fats can be divided into several categories, as follows:

Unsaturated fats

If you’ve heard the term “good fats,” this is what people are referring to. Unsaturated fats help:

  • Lower LDL cholesterol levels
  • Increase HDL cholesterol levels
  • Decrease inflammation in the body

They are divided into two main categories:

  1. Monounsaturated fats These fats are good for your heart. They lower bad cholesterol (LDL) and raise good cholesterol (HDL). Foods high in monounsaturated fats are: olive oil, avocados, nuts (like almonds and cashews), seeds (like pumpkin seeds), dark chocolate (70% cocoa or more)

  2. Polyunsaturated fats Another form of healthy fat is polyunsaturated fats, which include omega-3 and omega-6 fatty acids. They are found in: walnuts, flaxseeds and chia seeds, sunflower and safflower oils, fatty fish (like salmon and mackerel)

Saturated fats

Saturated fats are often labeled as "bad" fats. You can find them in foods such as: butter, red meat (beef, pork, lamb), tropical oils (coconut oil, palm oil), full-fat dairy products (cheese, whole milk, cream)

For a long time, saturated fats were thought to increase the risk of heart disease. This was because they can raise LDL cholesterol levels. However, recent studies suggest that this connection may not be so clear. Research indicates that the negative effects depend on the specific food source. Not all saturated fats affect health in the same way.

That said, consuming too much saturated fat can still raise your bad cholesterol levels and increase your risk of heart disease. The key is moderation. A little butter on your toast or a reasonable portion of red meat for dinner can be fine, but these foods shouldn’t dominate your fat intake.

Trans fats

If there’s one type of fat to limit as much as possible, it’s trans fats. These unhealthy fats are artificially made through a process called hydrogenation, which converts liquid oils into solid fats. You’ll often find trans fats in:

  • Processed snacks (potato chips, microwave popcorn)
  • Packaged baked goods (cookies, crackers, cakes)
  • Fried foods (French fries, doughnuts)
  • Margarine and shortening

Trans fats are harmful to heart health. They increase LDL cholesterol levels and lower good HDL cholesterol. This can lead to serious heart problems and increases the risk of heart disease, stroke, and type 2 diabetes.

Fortunately, many countries have begun to ban or heavily regulate trans fats in food. However, it’s still important to read labels for “partially hydrogenated oils,” which indicate the presence of trans fats. Even small amounts can be harmful.

Ways to include healthy fats in your meals

So how can you add healthy fats into your diet? Here are some simple tips:

  1. Replace butter with olive oil for cooking or as a salad dressing.
  2. Use avocado in place of mayo or other high-fat spreads in your meals.
  3. Opt for nuts or seeds as snacks rather than processed chips or crackers.
  4. Choose lean cuts of meat and reduce your intake of processed red meats like sausage or bacon.
  5. Include fatty fish like mackerel or salmon in your meals twice a week for extra omega-3 fatty acids.
  6. When shopping for packaged foods, always check the labels for trans fats and avoid anything with "partially hydrogenated oils."

Bottom line

To wrap it up, fats aren’t the villains they’ve been made out to be. In fact, some fats are important for keeping your heart healthy. The key is knowing which fats to consume and which ones to limit. So, next time you’re planning a meal, don’t be afraid of adding a little healthy fat into the mix—it’s good for your heart!
