Fats can help lower cholesterol

Dietary fat and cholesterol have a long and complicated history, but most modern recommendations say that eating a small amount of saturated fats and a larger amount of unsaturated fats can help improve your cholesterol levels. The Heart Foundation says that these healthy fats increase the amount of "good" cholesterol and lower the amount of "bad" cholesterol in your blood. Studies suggest that even some nutrient-rich foods that have saturated fats, such as eggs, could be helpful for improving cholesterol when eaten in moderation.

There are many factors that determine whether or not a person becomes clinically depressed; so if your loved one struggles with depression, it's probably not due to their diet.

Fats can reduce inflammation

Inflammation is the body's reaction to stressors, which can include anything from pollution to high-intensity exercise. Over the short term, inflammation is benign, but if it becomes chronic, inflammation can lead to serious and sometimes deadly diseases such as cancer. Poor diet can cause inflammation; it's wise to avoid eating the most inflammatory foods on a regular basis. However, some foods can actually be anti-inflammatory, meaning that they help combat this caustic reaction. Studies show that those who eat a diet high in unsaturated fats have lower levels of inflammatory markers in their blood.

Fats help keep your metabolism working

One of the hidden side effects of popular diets such as a low-fat diet is that they can really mess with your metabolism.

Fats are good for your heart

Sure, some fatty foods like burgers and french fries aren't great for your ticker, but a moderate and sufficient amount of dietary fat is crucial for maintaining heart health. In fact, diets focused on moderate fat consumption such as the Mediterranean diet have been shown in some studies to reduce the likelihood of cardiac arrest and other cardiovascular incidents. Of course, some of this is dependent on the types of fats consumed. Trans fats, for instance, have been shown to negatively affect risk factors for heart disease. Cardiologists recommend eating a larger amount of unsaturated fats, such as those from olive oil and avocado, than saturated fats, such as those from butter and animal products. There's a reason almonds, avocados and olive oil are among the best foods you can eat for your heart.
