GOOD FATS, BAD FATS, AND THE POWER OF OMEGA-3 fats

For years, nutritionists and doctors have preached the benefits of a low-fat diet. We’ve been told that reducing the amount of fat we eat is the key to losing weight, managing cholesterol, and preventing health problems. But when it comes to your mental and physical health, simply “cutting the fat” just doesn’t cut it.

Research shows that, more than the total amount of fat in your diet, it’s the types of fat you eat that really matter. Bad fats increase your cholesterol and your risk of certain diseases, while good fats have the opposite effect, protecting your heart and supporting overall health. In fact, good fats—such as omega-3 fats—are absolutely essential not only to your physical health but your emotional health as well.

Making sense of dietary fat

A walk down the grocery aisle will confirm our obsession with low-fat foods. We’re bombarded with supposedly guilt-free options: baked potato chips, fat-free ice cream, low-fat candies, cookies, and cakes. But while our low-fat options have exploded, so have obesity rates. Clearly, low-fat foods and diets haven’t delivered on their trim, healthy promises.

Despite what you may have been told, fat isn’t always the bad guy in the waistline wars. Bad fats, such as saturated fats and trans fats, are guilty of the unhealthy things all fats have been blamed for—weight gain, clogged arteries, and so forth. But good fats such as the monounsaturated fats, polyunsaturated fats, and omega-3s have the opposite effect.

As a matter of fact, healthy fats play a huge role in helping you manage your moods, stay on top of your mental game, fight fatigue, and even control your weight.

The answer isn’t cutting out the fat—it’s learning to make healthy choices and to replace bad fats with good ones that promote health and well-being.

Myths and facts about fats

Myth: All fats are equal—and equally bad for you.

Fact: Saturated fats and trans fats are bad for you because they raise your cholesterol and increase your risk for heart disease. But monounsaturated fats and polyunsaturated fats are good for you, lowering cholesterol and reducing your risk of heart disease.

Myth: Lowering the amount of fat you eat is what matters the most.

Fact: The mix of fats that you eat, rather than the total amount in your diet, is what matters most when it comes to your cholesterol and health. The key is to eat more good fats and less bad fats.

Myth: Fat-free means healthy.

Fact: A “fat-free” label doesn’t mean you can eat all you want without consequences to your waistline. Many fat-free foods are high in sugar, refined carbohydrates, and calories.

Myth: Eating a low-fat diet is the key to weight loss.

Fact: The obesity rates for Americans have doubled in the last 20 years, coinciding with the low-fat revolution. Cutting calories is the key to weight loss, and since fats are filling, they can help curb overeating.

Types of dietary fat: Good fats vs. bad fats

To understand good and bad fats, you need to know the names of the players and some information about them. There are four major types of fats:

• monounsaturated fats
• polyunsaturated fats
• saturated fats
• trans fats

Monounsaturated fats and polyunsaturated fats are known as the “good fats” because they are good for your heart, your cholesterol, and your overall health.

GOOD FATS

Monounsaturated fat
Polyunsaturated fat

• Olive oil
• Canola oil
• Sunflower oil
• Peanut oil
• Sesame oil
• Avocados
• Olives
• Nuts (almonds, peanuts, macadamia nuts, hazelnuts, pecans, cashews)
• Peanut butter

• Soybean oil
• Corn oil
• Safflower oil
• Walnuts
• Sunflower, sesame, and pumpkin seeds
  Flaxseed
• Fatty fish (salmon, tuna, mackerel, herring, trout, sardines)
• Soymilk
• Tofu

Saturated fats and trans fats are known as the “bad fats” because they increase your risk of disease and elevate cholesterol.

Appearance-wise, saturated fats and trans fats tend to be solid at room temperature (think of butter or traditional stick margarine), while monounsaturated and polyunsaturated fats tend to be liquid (think of olive or corn oil).

BAD FATS

Saturated fat
Trans fat

• High-fat cuts of meat (beef, lamb, pork)
• Chicken with the skin
• Whole-fat dairy products (milk and cream)
• Butter
• Cheese
• Ice cream
• Palm and coconut oil
• Lard

• Commercially-baked pastries, cookies, doughnuts, muffins, cakes, pizza dough
• Packaged snack foods (crackers, microwave popcorn, chips)
• Stick margarine
• Vegetable shortening
• Fried foods (French fries, fried chicken, chicken nuggets, breaded fish)
• Candybars

General guidelines for choosing healthy fats

With so many different sources of dietary fat—some good and some bad—the choices can get confusing. But the bottom line is simple: don’t go no-fat, go good fat.

If you are concerned about your weight or heart health, rather than avoiding fat in your diet, try replacing saturated fats and trans fats with good fats. This might mean replacing some of the meat you eat with beans and legumes, or using olive oil rather than butter.

• Try to eliminate trans fats from your diet. Check food labels for trans fats. Avoiding commercially-baked goods goes a long way. Also limit fast food.
• Limit your intake of saturated fats by cutting back on red meat and full-fat dairy foods. Try replacing red meat with beans, nuts, poultry, and fish whenever possible, and switching from whole milk and other full-fat dairy foods to lower fat versions.
• Eat omega-3 fats every day. Good sources include fish, walnuts, ground flax seeds, flaxseed oil, canola oil, and soybean oil.
