Walnuts are one of the best sources of omega-3 fatty acids, specifically alpha linoleic acid, an omega-3 found in plants. A recent study linked a handful per day to lower total cholesterol and LDL cholesterol as well as improved blood vessel function. Research has also shown that eating nuts appears to reduce the risk of blood clots that can cause heart attacks as well as improve the health of the lining of our arteries.
Confused yet? Why would our body break something down to just put it back together? Long-chain fatty acids are insoluble in blood and in order to transport these across, triglycerides are packaged into chylomicrons that are basically a vehicle that gets released into the lymphatic system and eventually in the blood for circulation. When chylomicrons reach the capillaries of muscle and fat tissue, they activate lipoprotein lipase (stay with me here).
Saturated fats are found in animal products (meat, poultry skin, high-fat dairy, and eggs) and in vegetable fats that are liquid at room temperature, such as coconut and palm oils. The 2005 Dietary Guidelines recommend limiting saturated fats to 10% or less of your total calories, while the American Heart Association recommends keeping them to just 7% of total calories.
Incorporating healing fats into your diet has many health benefits. Healing fats provide building blocks for cell membranes and hormones. They also function as carriers for important fat-soluble vitamins such as vitamins A, D, E, and K and aid in the absorption of minerals. Healing fats are essential for a healthy body and lifestyle. Let’s look more closely at several healing fats.
Get more avocados in your diet by trying one of these avocado recipes. Alternatively, use it to cook with by adding avocado oil to your kitchen pantry. It has a mild taste that won’t overpower dishes the way other oils might and also has a high smoke point, which means it works well for grilling or frying. And because it remains a liquid at room temperature, it’s a tasty choice to drizzle on salads, sandwiches or veggies.
Investigators looked at the relationship between saturated fat intake and coronary heart disease (CHD), stroke, and cardiovascular disease (CVD). Their controversial conclusion: “There is insufficient evidence from prospective epidemiologic studies to conclude that dietary saturated fat is associated with an increased risk of CHD, stroke, or CVD.”(13)
But while there’s still a good amount of debate on the question “Is saturated fat bad?,” there’s no arguing that trans fats should be cut out of your diet altogether. Trans fats are often added to foods through a process called hydrogenation, which is used to increase the flavor and texture while extending the shelf-life of foods like vegetable oils.

For years, only true diet detectives knew whether a particular food contained trans fat. This phantom fat was found in thousands of foods, but only those familiar with the “code words” partially hydrogenated oil and vegetable shortening knew when it was present. Fortunately, after a large body of research in the 1990s sounded the alarm on its deleterious health effects, a series of policy initiatives led to the near elimination of artificial trans fat in the U.S. food supply by 2018. However, the road to eliminating trans fat was not so straightforward, and outside the U.S. there’s still more work to be done. In many developing nations, trans fat intake remains high.Read more about the key research and policy initiatives shining the spotlight on harmful trans fats.
Several studies explore and show the this type of saturated fat in coconut does not negatively affect cholesterol levels nor overall heart health like we were once told. Some studies have shown coconut oil moderately increases metabolic rate, which is often a “selling” point that it helps boost your metabolism and contribute to fat loss or weight control. I’ll let these studies here, here, and here tell you what we do know.
