All The Fuss About Fats



Fats often get a bad rap in the world of nutrition, but the truth is, they’re essential for our health. From fueling our brains to supporting our hearts, fats play a vital role in keeping us healthy. The type of fat you choose, however, can make all the difference. In this essay, we’ll dive into the world of fats—comparing plant-based oils like olive and avocado oil, seed oils, and animal fats. We’ll explore their nutritional profiles, and how they affect your health.

Understanding Fats: A Quick Overview

Not all fats are created equal. On one side, we have plant-based oils, known for their heart-friendly properties and vibrant health benefits. On the other, we have seed oils—ubiquitous in processed foods—and animal fats, staples of traditional diets. Each comes with its own set of advantages and challenges.

Plant-based fats, like those found in olives and avocados, are rich in monounsaturated fats (MUFAs) and antioxidants, offering benefits for heart health, brain function, and inflammation control. Seed oils, such as soybean and sunflower oil, are affordable and widely used but are often processed to the point of losing their nutritional value. Animal fats, like butter and lard, are stable under heat but high in saturated fats, which can raise cholesterol and increase cardiovascular risks.

Our mission here is simple: to explore how these fats affect our health and why plant-based fats emerge as the healthiest option for your pantry.

Nutritional Breakdown: What’s in Your Oil?

Let’s start with the basics: what makes up these fats?

Plant-Based Fats: Oils like olive and avocado are high in MUFAs, which help lower bad cholesterol (LDL) and increase good cholesterol (HDL). Olive oil is also packed with polyphenols—compounds that fight inflammation and protect your heart. Avocado oil is equally impressive, boasting nutrients like vitamin E and lutein, which are great for your skin and eyes.

Animal Fats: Butter, lard, and tallow are high in saturated fats. While stable for cooking, these fats are notorious for raising LDL cholesterol, a known risk factor for heart disease. While they contain some fat-soluble vitamins (like vitamin A), their benefits are often overshadowed by their health risks.

Seed Oils: Seed oils like soybean and sunflower oil are rich in polyunsaturated fats, particularly omega-6 fatty acids. While omega-6 is essential, consuming too much (which is common in modern diets) can lead to chronic inflammation. Processing also strips these oils of any antioxidants, making them prone to oxidation and harmful byproducts.

Cooking Smarts: How Fats Hold Up Under Heat

Cooking adds another layer to the story. Heat can change the structure of fats, sometimes for the worse.

Plant-based oils like avocado oil excel here, with a high smoke point of 520°F, making it perfect for frying and roasting. Extra virgin olive oil, though best for low-to-medium heat, contains antioxidants that protect it from breaking down, even at higher temperatures.

Seed oils, on the other hand, are a risky choice. Their polyunsaturated fats oxidize quickly when exposed to heat, forming harmful compounds linked to inflammation and chronic diseases. Animal fats are more heat-stable, but cooking with them often introduces saturated fats and cholesterol into your meals, which may not be ideal for heart health.

The Omega-6 to Omega-3 Balance: Why It Matters

Modern diets are flooded with omega-6 fatty acids, largely due to the widespread use of seed oils. These fats, while necessary in small amounts, dominate our diets and throw off the balance with omega-3s—essential fats found in fish, flaxseeds, and walnuts. This imbalance can lead to inflammation, increasing the risk of chronic diseases like heart disease and arthritis.

Plant-based oils, like olive and avocado, are naturally low in omega-6 and work beautifully alongside omega-3-rich foods to restore a healthier balance. Toss a salad with olive oil and walnuts, and you’re on the right track!

Health Effects: What Science Says

Fats can make or break your health, depending on their type.

Heart Health: Saturated fats from animal products are known to raise LDL cholesterol, increasing heart disease risk. In contrast, plant-based oils like olive oil reduce LDL and boost HDL, actively protecting your heart.

Brain Function: The brain thrives on healthy fats. MUFAs in olive and avocado oil enhance memory, protect neurons, and fight inflammation. Meanwhile, oxidized seed oils and excessive saturated fats can harm cognitive function over time.

Inflammation: Olive oil’s antioxidants and polyphenols are powerful inflammation fighters, while the pro-inflammatory effects of omega-6 dominance from seed oils can have the opposite effect.

Toxins and Processing: The Hidden Story

Not all fats are pure. Seed oils often contain pesticide residues from heavily farmed crops and can be chemically refined using solvents like hexane. Similarly, animal fats may harbor toxins like dioxins or heavy metals from industrial farming practices.

By contrast, high-quality, minimally processed plant-based oils—especially organic options—are much cleaner. Cold-pressed olive and avocado oils retain their natural nutrients without harmful additives, making them a safe and healthy choice.

Practical Tips: How to Incorporate Healthier Fats

Switching to plant-based fats doesn’t have to be complicated. Here are a few easy ways to get started:

1.Cooking: Use avocado oil for high-heat methods like frying or grilling and olive oil for sautéing and roasting.

2.Salads and Dips: Drizzle extra virgin olive oil over salads, grain bowls, or roasted vegetables. Add mustard, vinegar, lemon juice, etc to round out your dressing.

3.Snacks: Replace processed snacks made with seed oils with whole foods like nuts, seeds, or olives.

4.Baking: Swap butter or margarine for olive oil in recipes—it’s healthier and adds a subtle, delicious flavor.


The evidence is clear: plant-based fats like olive and avocado oil are the healthiest and most versatile options for your diet. They support heart health, cognitive function, and overall well-being while minimizing exposure to harmful toxins and additives.

By reducing your reliance on seed oils and saturated animal fats and focusing on high-quality, minimally processed plant-based options, you can transform your diet and improve your long-term health. So, stock up on that bottle of extra virgin olive oil—it’s a small change with big benefits!

Carbs Arn't The Only Culprit - Type 2 Diabetes Deep Dive

Click HERE to read the "short & sweet" version. Although to truly understand the complexity of this subject I recommend taking the time to read this Deep Dive. What is Type 2 Diabetes? Type 2 diabetes is a chronic metabolic condition characterized by insulin resistance and insufficient insulin production. Insulin, a hormone produced by the pancreas, helps regulate blood sugar by facilitating glucose uptake into cells for energy. In type 2 diabetes, cells become resistant to insulin’s effects, and the pancreas fails to produce enough insulin to maintain normal blood sugar levels, leading to hyperglycemia (high blood sugar). Prevalence in the U.S. As of 2021, approximately 38.4 million Americans—11.6% of the population—are diagnosed with diabetes, with type 2 diabetes accounting for 90–95% of cases. Additionally, an estimated 8.7 million adults remain undiagnosed. These statistics underscore the need for increased awareness and early detection. Can Diabetes Develop in Heal...

Artificial Sweeteners vs. Sugar - Deep Dive

Artificial Sweeteners vs. Sugar: Understanding the Acceptable Daily Intake (ADI) The Acceptable Daily Intake (ADI) is a critical benchmark established by health authorities like the FDA and WHO to determine the maximum amount of a substance—such as a non-nutritive sweetener (NNS) or sugar—that can be consumed daily over a lifetime without significant health risks. To explore the differences between artificial sweeteners and sugar, let’s examine their ADI values and how these translate into real-world examples, using an individual weighing 180 pounds and soda as a reference. 1. Calculating ADI: Artificial Sweeteners (NNS) Artificial sweeteners such as aspartame, sucralose, and saccharin are widely used in foods and beverages. The ADI for these sweeteners is measured in milligrams per kilogram of body weight per day (mg/kg/day). For a 180-pound person (equivalent to approximately 82 kg), let’s calculate the ADI and provide examples using a standard 12-ounce can of soda. Aspartame ADI: 50...

Dietary Fats - The Deep Dive

Before you read the rest, this is a deep dive into the topic of fats. If you want a shorter version that still aims to be informative, read this post instead! Dietary fats are a crucial component of human nutrition, providing a dense source of energy, aiding in the absorption of fat-soluble vitamins, and serving as building blocks for cell membranes and hormones. However, not all fats are created equal, and their sources and composition can significantly impact overall health. Traditionally, fats have been categorized into three main groups: seed oils, animal-based fats, and plant-based fats. These categories represent diverse origins, fatty acid profiles, and roles in human metabolism. In recent decades, seed oils like soybean, corn, and canola oil have become dietary staples due to their cost-effectiveness and prevalence in processed foods. Simultaneously, animal-based fats, such as butter, lard, and tallow, have been staples in many traditional diets but are often criticized for th...
