Introduction
 For years, we were told that fats were the devil. Low fat this and fat free that, no more eating meat and eggs, and a drastic increase consumption of refined grains. I should specify that I have never been on a keto (high fat, low carb) diet. But it is evident how wrong we got it. In correct moderation and from the proper sources, fats are essential for daily life, and their replacement with more starch and sugar has been the main fuel for the recent obesity epidemic.

  


 There’s 3 main categories of fats: unsaturated fat, saturated fat, and trans fats. Think of these types of fats as a traffic light, where green is unsaturated, yellow is saturated, and red is trans.

  


Unsaturated Fat
 Unsaturated fats are typically thought of as the healthiest fat, and are broken down into mono-unsaturated fats and poly-unsaturated fats. Increased unsaturated fat consumption has been shown to decrease inflammation, improve cholesterol, and support heart health. In their pure form, these fat’s are liquid at room temperature. Think olive oil or canola oil (unsaturated fats) as opposed to coconut oil or butter (saturated fats). Foods high in unsaterated fats include avocados, olives, nuts, seeds, and salmon.

  


Saturated Fat
 Saturated fats are somewhere in the middle, like a yellow light. Sometimes you need to speed up, and sometimes you need to slow down. Saturated fats are typically solid at room temperature, such as butter, lard, ghee, and coconut oil. The downside is that high saturated fat consumption is linked to increased cholesterol, blood pressure, and other heart related issues. However, adequate consumption of saturated fats is necessary for promoting healthy liver, bones, brain, heart, and nervous system. Foods high in saturated fats include meats, eggs, and dairy.

  


Trans Fat
 Trans fats are easily the most harmful type of fat, and should be avoided at all costs. They’re so dangerous that the FDA outlawed them in the United States in 2018. Consumption of trans fats are shown to increase LDL and decrease HDL, leading to an increased risk of diabetes, heart attack, and stroke. They’re creating by fully hydroginating unsaturated fats, and are used to make products more shelf stable. They’re typically found in products such as margarine and vegetable oil spread, fried foods, no stir peanut butter, microwave popcorn, and packaged baked goods.

  


Fats: Risks
 Outside of trans and saturated fats, the main thing you’ll hear people comment about fat is calories. While carbs and protein each have about 4 calories per gram, fats on the other hand contain 9 calories per gram. That means that any fatty food, both healthy and unhealthy, will inherently be higher in calories. And while nutrition does go far beyond pure calorie count, is it very important to acknowledge that fatty foods are higher in calories. Thus, consumption must be properly moderated as to not go over your caloric budget and cause unexpected weight gain.

  


Fats: Benefits
 The main benefit of fats is that they help your body absorb fat soluble vitamins. As opposed to water soluble vitamins (such as all the B vitamins, vitamin C, and all minerals), fat soluble vitamins need to be consumed with fat in order to actually reap the benefits. These include vitamins A, D, E, and K. Have you ever wondered why a vitamin D supplement is a soft gel pill, as opposed to a hard regular pill? This is why; it’s packaged with an oil to help your body absorb the nutrients.

  


 Proper consumption of healthy fats is critical for regulating your blood pressure and cholesterol, as well as maintaining nerve and brain function. Omega-3 fats in particular are extremely important; these are anti-inflammatory and lower your risk for diabetes, obesiety, CVD (cardiovascular disease), blood clots, cancer, and Alzheimer’s. Omega-3 fats are found in fatty fish like salmon and mackerel, and seeds like chia and flax. There are 3 main types:
- ALA (alpha-linolenic acid)
- DHA (docosahexaenoic acid)
- EPA (eicosapentaenoic acid)
