Is olive oil good for you? Believe it or not, the olive oil benefits are so profound that almost any diet should include it. First, extra virgin olive oil (EVOO) is great for heart health. In fact, olive oil consumption has been linked to lower blood pressure, reduced cholesterol levels and improved blood vessel function. (14, 15, 16) The high amount of antioxidants in EVOO means it protects your cells from damage. It also helps improve memory and cognitive function and works as an anti-inflammatory agent. (17) Since inflammation is at the root of most diseases, this is a biggie! (18)

Meanwhile, the official unsaturated fat definition encompasses any type of fatty acid that contains at least one double bond within the chain. These fats are further classified as either a monounsaturated fat or polyunsaturated fat based on the number of double bonds they contain. Unsaturated fats can include foods like vegetable oils, nuts, seeds and fish.
Not only does dark chocolate taste great, but it’s also considered a superfood as well. It’s high in fat and rich in antioxidants, which help protect our bodies from disease-causing free radicals. The flavanols found in dark chocolate also improve heart health, thanks to their ability to lower blood pressure and get more blood flowing to the heart and the brain. (31) And if you’ve ever found that nibbling on a piece of chocolate helps you focus, you’re not alone. It’s a brain food that actually helps improve cognitive performance. (32)
Eggs are an inexpensive and easy source of protein. People often think egg whites are a healthier option than whole eggs because they contain less fat, but while it's true that the egg yolk contains some fat, it's also packed with important nutrients. One whole egg contains 5 grams of fat, but only 1.5 grams are saturated. Whole eggs are also a good source of choline (one egg yolk has about 300 micrograms), an important B vitamin that helps regulate the brain, nervous system, and cardiovascular system. As for the cholesterol? The latest nutrition research has found that eating cholesterol doesn't raise our blood cholesterol. In fact, research has linked moderate egg consumption to improved heart health.
Saturated fat. This is a type of fat that comes mainly from animal sources of food, such as red meat, poultry and full-fat dairy products. Saturated fat raises total blood cholesterol levels and low-density lipoprotein (LDL) cholesterol levels, which can increase your risk of cardiovascular disease. Saturated fat may also increase your risk of type 2 diabetes.
Healthy fats are easy to incorporate into snacks or appetizers. Guacamole served with sliced raw vegetables is one of the healthiest appetizers/snacks you can have. Walnuts and other nuts are delicious and crunchy. Nut butters are wonderful with celery sticks and other crunchy, raw vegetables. You can also top sliced granny smith apples with nut butters or layer slices of apples with slices of grass-fed cheese. Grass-fed cheese is also delicious with olives and is very satisfying.
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.
The type of fat with no redeeming nutritional value is trans fat, which is created when food manufacturers artificially convert unsaturated fatty acids into solid, saturated fats. Trans fats have the worst effect on your cholesterol levels, because they actually lower the good HDL cholesterol and increase the harmful LDL cholesterol. They're also highly inflammatory, which may contribute to chronic diseases, and they contribute to insulin resistance, which drives diabetes development.
One cup of black olives has 15 grams of fat, but again, it is mainly monounsaturated. Plus, no matter what variety of olive you enjoy, they all contain many other beneficial nutrients as well, such as hydroxytyrosol, a phytonutrient that has long been linked to cancer prevention. New research is showing that this phytonutrient may play a role in reducing bone loss as well. And if you have allergies or other inflammatory conditions, olives might be just the snack for you as research suggests that olive extracts function as anti-histamines on the cellular level. Even with all these benefits, it is important to be mindful of your serving size as olives can be high in sodium. Stick to 5 large or 10 small olives as the perfect portion.
Omega-3 fatty acids promote health in several ways. They reduce inflammation and lower the risk of chronic diseases including heart disease, cancer, and arthritis. Omega-3 fatty acids can help lower triglycerides and apoproteins (markers of diabetes), and raise HDL (“good” cholesterol) levels (8). Omega-3 fats are also essential for brain and eye health (9).
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).
A handful of nuts goes a long way! They provide a protective benefit for heart health and contain what is known as good fat. Nuts help to burn calories more efficiently and are proven to add a satiety factor into your daily diet. This, Warren says, helps with not overloading on calories from other foods. A creative way to use nuts as salad add-ins is by whipping up a simple nut sauce made with almond butter to dress your salad. You can also chop a few of your favorites—almonds and walnuts are particularly good in salads—and sprinkle them in.
Avocado: One of the most widely known healthy fats, avocado makes an ideal addition to any dish at breakfast, lunch or dinner. It's also perfect as a stand alone snack! This powerhouse of a superfood isn't only a monounsaturated fat – it's also loaded with folate, potassium, fiber and vitamins E, C and B6. Don't forget to cook the pulp and eat it as well- the avocado seed is loaded with essential vitamins too! Don't let it go to waste!
