How Eating Fat Makes You Healthy
The low-fat, high-carb mantra of the eighties and early nineties was well intentioned, but it missed the mark. In the years since, science has shown that fat is actually your friend. In fact, eating enough healthy fat is what makes you feel full, allows for the absorption of fat-soluble nutrients like vitamins A, E, D and K, and nourishes your brain, which itself is 60 percent fat.
That said, not all fats are created equal. For example, trans fats—often listed as “partially hydrogenated oils” on the labels of processed foods and baked goods—have a bad reputation for good reason. Created using an industrial process that adds hydrogen to liquid vegetable oils to make them more solid, these fats can raise LDL (bad cholesterol) and have been repeatedly linked to heart disease.
Saturated fat, on the other hand, is not the danger you might have been led to believe. Healthy saturated fats from high-quality, minimally processed animal and vegetable sources provide sustained energy for the body, as well as serving as the building blocks of cell membranes and hormones.
Getting enough good fats from both saturated and unsaturated sources can make a difference in how you look and feel. Here are a few of our favorite options:
Unlike most other fruits, which are high in carbohydrates, avocados are three-quarters fat. Eating this kind of monounsaturated fat has been shown to raise levels of good cholesterol while lowering the bad. What’s more, even though they are high in fat and calories, one study showed that people who eat avocados tend to weigh less and have less belly fat than those who don’t.
Tip: Spread avocado instead of mayo on sandwiches, or blend with herbs and lemon juice to make a creamy salad dressing.
Coconut oil is a good source of both natural saturated fat and medium-chain fatty acids, which are easy for the body to store as energy and can improve brain and memory function. Coconut oil also contains a hefty dose of lauric acid, which has antiviral and antibacterial properties.
Tip: Add a teaspoon to your morning smoothie, or use in place of other oils when cooking or baking.
Packed with healthy fats, protein and fiber, nuts are also high in vitamin E and magnesium. Research has shown that nut eaters are generally thinner, have a reduced risk of heart disease and are less likely to develop type 2 diabetes.
Tip: Since nuts are high in calories, keep serving size in check. A 200-calorie serving of almonds is about 29 nuts, while it only takes 8 walnuts to meet this mark.
Wild-caught salmon is a great source of DHA and EPA, two omega-3 fatty acids that can reduce inflammation and lower the risk of heart disease and some cancers. Trout, mackerel and sardines are other great sources of these healthy fats.
Tip: Instead of chicken or tuna, try salmon salad made with yogurt in place of mayo, along with herbs, Dijon mustard and sunflower seeds.
