Since sources of fat are more calorie-dense, it is important to understand what a serving of a fat is equivalent to. For example, one teaspoon of butter, margarine or mayonnaise is one fat serving. For times when you may not have a measuring spoon available, a visual equivalent of one teaspoon is the tip of your thumb. See below for examples of serving sizes for added fats.
Polyunsaturated fats can also be healthy. The two main types are omega-3 and omega-6 fatty acids, essential fats our bodies need for brain function and cell growth. Omega-3s are beneficial for every aspect of heart health, and are mostly found in fish and algae, nuts, and seeds. “Other polyunsaturated fats, [omega-6s], can be found in certain plant-based oils,” Hunnes adds. “They’re not particularly harmful, but not necessarily beneficial the way omega-3s and monounsaturated fats are.” Omega-6s work alongside omega-3s to lower LDL cholesterol, but research suggests that eating more omega-6 than -3 may contribute to inflammation and weight gain, so the key is to make sure your omega-3 intake is always higher.
Additionally, a higher consumption of eggs can reduce your risk of metabolic syndrome, a cluster of conditions including factors like excess body fat, high blood sugar levels and abnormal cholesterol levels. Having any of these conditions makes you more likely to suffer from heart disease, stroke or type 2 diabetes. A 2016 study found that adults over 40 years old who regularly ate eggs significantly reduced their risk of metabolic syndrome. (10)
Polyunsaturated fats can primarily be found in plant-based foods and oils. Similar to monounsaturated fats, polyunsaturated fats can decrease the risk of heart disease by lowering levels of blood cholesterol (9). A certain type of polyunsaturated fat, omega-3 fatty acids have been found to be particularly beneficial for heart health. They not only lower the risk of coronary artery disease but can also lower blood pressure and protect against irregular heartbeats (9). Omega-3 fatty acids can be easily consumed by eating fatty fish such as salmon, sardines and trout.
