Key Takeaways

Healthy Fat Sources: Making Smart Choices

As with everyone else, I used to be a fat-phobe and was swept up in the ‘low-fat everything’ movement of the 1990s.

But after years of research and testing out different dietary approaches on myself, I have found that healthy fats are not only good for you—they’re essential to your well-being.(1)

I understand where you’re coming from, and I’m here to share my knowledge and experience with you.

Those grocery store shelves that used to be so full of “fat-free” foods?

We’ve since realized that this craze took us down the wrong path.

The truth about fats is far more interesting and valuable to your health.

Let me tell you about what I’ve discovered through my journey of gaining more knowledge on fats.

Here’s what happens when you don’t eat enough healthy fats:(2)

• Your energy levels drop significantly, making it hard to get through the day without feeling exhausted
• Your skin becomes dry and may show signs of premature aging due to lack of essential fatty acids
• Your body struggles to absorb important fat-soluble vitamins, potentially leading to deficiencies

The main types of healthy fats you need in your diet:

• Monounsaturated fats found in olive oil, avocados, and nuts help protect your heart health and reduce inflammation.
• Polyunsaturated fats, including omega-3s from fatty fish and omega-6s from seeds, support brain function and joint health.

Steps to incorporate more healthy fats into your daily meals:

1. Start your day with eggs cooked in olive oil, or add avocado to your morning toast
2. Include a handful of nuts or seeds as your mid-morning or afternoon snack
3. Use olive oil-based dressings on your salads instead of fat-free options
4. Eat fatty fish like salmon or mackerel at least twice a week

Benefits I’ve personally experienced since increasing healthy fats:

• Clearer skin and fewer breakouts
• More stable energy throughout the day without crashes
• Better mental focus and concentration
• Reduced hunger between meals

For someone eating 2,000 calories a day, aim for 44-77 grams of healthy fats.

But remember, it’s not just about numbers—focus on quality sources and listen to your body’s needs.

Let me share a personal revelation that changed my approach to fats.

A few years ago, I was training for a half-marathon and following what I thought was a “healthy” low-fat diet.

Despite my training, I felt constantly tired, and my recovery times were terrible.

My running coach recommended adding more healthy fat to my diet, specifically emphasizing foods rich in omega-3.

The change was incredible – my energy stabilized, my joints improved, and my recovery from running significantly increased.

Discovering the role of fat in hormone production was another wake-up call for me.

Our bodies need healthy fats to produce and regulate many hormones, including those that control metabolism, mood, and stress response.

When I learned this, it accounted for why my mood had been so unstable during my low-fat years.

Quality matters significantly where fats are concerned.

I discovered this the hard way when I was experimenting with different cooking oils.

Extra virgin olive oil, for example, contains strong antioxidants and anti-inflammatory compounds that you just won’t find in refined vegetable oils.

Similarly, the omega-3s in wild salmon are more concentrated and of higher quality than in farm-reared fish.

Understanding this can provide you with assurance that you’re getting the best food for your health.

Temperature for Cooking with Fats

I discovered that some healthy fats, like extra virgin olive oil, are best used for low to medium-heat cooking or as dressings, while others, like avocado oil, can withstand higher temperatures without breaking down.

This knowledge helped me maintain the nutritional benefits of these healthy fats in my cooking.

Start small if you want to include more healthy fats in your diet. These simple changes can significantly improve how you feel.

Remember, transitioning to a diet rich in healthy fats is a journey, not a race.

Pay attention to how different fats make you feel and adjust accordingly. The key is finding a balanced approach for your body and lifestyle.

20 Best Fat Sources

1. Wild Salmon (11g fat/3 oz) 

Imagine biting into a perfectly cooked piece of wild salmon – that rich, buttery texture comes from its impressive healthy fat content.

Wild salmon is special because of its exceptional omega-3 profile, particularly EPA and DHA, which directly support brain health and reduce inflammation.(4)

I’ve noticed a significant difference in quality between wild and farmed salmon, with wild varieties offering a more concentrated nutrient profile.

My favorite way to prepare it is a simple pan-sear with herbs, which preserves those precious omega-3s while creating a delicious crust.

2. Mackerel (15.7g fat/3 oz) 

Often overlooked in favor of salmon, mackerel deserves more attention in your kitchen.

This fatty fish contains more healthy fats per serving than its popular cousin.

What fascinates me about mackerel is its dual benefit – not only is it packed with heart-healthy omega-3s and one of the best natural sources of vitamin B12.

My cooking experiments show that its rich flavor stands up beautifully to bold seasonings and high-heat cooking methods.

3. Sardines (11.5g fat/3 oz) 

Let me tell you why sardines have become my go-to emergency protein source.

These tiny powerhouses pack an incredible nutritional punch – one of the few foods naturally containing vitamin D and healthy fats.

What’s more remarkable is that when you eat them whole, you get a significant calcium boost from their soft, edible bones.

For those worried about the “fishy” taste, try the ones packed in olive oil with lemon – they’re a game-changer for both nutrition and flavor.

4. Eggs (5g fat/large egg) 

The humble egg might seem simple, but its fat composition tells an incredible story.

The yolk contains nearly all of the egg’s healthy fats, arranged in a unique phospholipid structure that our bodies love.(5)

I’ve learned through years of cooking that eggs are incredibly versatile – whether making a quick scramble or incorporating them into baked goods, their fats remain stable and nutritious.

Most fascinating is how the egg’s fat content varies based on the chicken’s diet, which is why I always opt for pasture-raised eggs when possible.

5. Grass-fed Butter (12g fat/tbsp)

After years of avoiding butter, discovering the truth about grass-fed butter transformed my cooking.

The golden color comes from its high concentration of fat-soluble vitamins, particularly vitamin K2, which is rare in modern diets.

Unlike conventional butter, grass-fed varieties contain higher levels of conjugated linoleic acid (CLA), a unique fatty acid that supports metabolic health.(6)

I’ve found it adds an incomparable richness to both sweet and savory dishes.

6. Extra Virgin Olive Oil (14g fat/tbsp) 

My journey with extra virgin olive oil began during a cooking class in Italy, where I learned that not all olive oils are created equal.

The best varieties contain high levels of polyphenols, antioxidant compounds that protect both the oil and your body.

The peppery kick at the back of your throat?

That’s from oleocanthal, a natural anti-inflammatory compound.(7)

I store mine in a dark glass bottle away from heat to preserve these delicate compounds.

7. Coconut Oil (14g fat/tbsp) 

What makes coconut oil unique is its medium-chain triglycerides (MCTs) behave differently in your body than other fats.

They’re processed more like carbohydrates, providing quick energy rather than being stored.

Through my kitchen experiments, I’ve discovered that coconut oil is perfect for high-heat cooking due to its stable structure.

Its subtle sweetness adds an interesting dimension to savory and sweet dishes.

8. Almonds (14g fat/oz) 

Think of almonds as nature’s perfect snack package.

Their fat content comes primarily from monounsaturated fats, the same heart-healthy type found in olive oil.

What sets almonds apart is their impressive vitamin E content—just a handful provide 37% of your daily needs.

I’ve found soaking them overnight improves digestibility and brings out a subtle sweetness that makes them even more enjoyable.

9. Walnuts (18g fat/oz) 

Walnuts’ wrinkled exterior mirrors the composition of our brain – and again, very interestingly, that indicates their intellectual benefits.

Walnuts contain a unique combination of omega-3 fatty acids and alpha-linolenic acid (ALA), which support brain activity.

Other nuts do not provide plant-based omega-3s as hard to find elsewhere in the vegetable kingdom.

From personal experience, I have learned that a light toasting of walnuts enhances their buttery flavor and the bioavailability of their nutrients.

10. Macadamia Nuts (21.5g fat/oz) 

When it comes to monounsaturated fats, macadamia nuts reign supreme in the nut world.

Their fat profile closely resembles that of olive oil, which explains their buttery, rich taste.

What makes them truly special is their low omega-6 to omega-3 ratio, something rare in today’s diet.

I’ve discovered they’re incredibly satisfying—just a small handful can curb hunger for hours due to their optimal fat content.

11. Pine Nuts (19.1g fat/oz) 

Let me share something fascinating about pine nuts: they’ve been prized for their healthy fats since ancient Roman times.

These tiny powerhouses contain a unique fatty acid called pinolenic acid, which some studies suggest may help support healthy weight management by increasing satiety hormones.

In my kitchen experiments, I’ve found that lightly toasting pine nuts release their essential oils, intensifying both their nutrient availability and nutty flavor.

12. Brazil Nuts (19g fat/oz) 

Did you know that just one Brazil nut can meet your daily selenium needs?

This mineral synergizes with the nut’s healthy fats to support thyroid function and immune health.

Their fat content is primarily saturated, but don’t let that worry you – it’s a different type than what’s found in processed foods.

I limit myself to 2-3 Brazil nuts daily to avoid excessive selenium intake while still benefiting from their healthy fats.

13. Chia Seeds (9g fat/oz)

These tiny seeds expand to absorb up to 10 times their weight in liquid, creating a unique gel-like consistency.

Combined with their omega-3 content, this property makes them incredibly versatile in the kitchen.

I’ve found that adding chia seeds to smoothies or overnight oats boosts the nutrition profile and creates a satisfying texture that keeps me full for hours.

Their mild flavor makes them an easy addition to almost any dish.

14. Flaxseeds (4.3g fat/tbsp) 

The story of flaxseeds goes back thousands of years, but their nutritional importance has never been more relevant than today.

These tiny brown or golden seeds are unique because they contain soluble and insoluble fiber and healthy fats.

Their lignans content makes them particularly special – they contain up to 800 times more lignans than other plant foods.

I’ve learned to grind them fresh before use since whole flaxseeds can pass through your system undigested, preventing you from accessing their valuable nutrients.

15. Hemp Seeds (15g fat/3 tbsp) 

Unlike many plant foods, hemp seeds offer something remarkable: a perfect ratio of omega-6 to omega-3 fatty acids alongside all essential amino acids.

They have a subtle nutty flavor that reminds me of pine nuts but with a softer texture.

From my experience, hemp seeds require no preparation – no grinding or soaking needed.

They’re among the few seeds that provide complete protein and optimal fatty acids, making them especially valuable for plant-based diets.

16. Pumpkin Seeds (13.9g fat/oz) 

Often overlooked outside of the fall season, pumpkin seeds are nutritional champions for mineral content.

Their healthy fat content helps your body absorb their impressive zinc and magnesium levels.

I’ve discovered that lightly roasting them at a low temperature (around 170°F) preserves their delicate oils while enhancing their flavor.

The green color indicates high chlorophyll content, adding to their nutritional benefits.

17. Avocado (15g fat/half) 

There’s something magical about how nature packages avocados’ healthy fats.

The monounsaturated fats in avocados are protected by the fruit’s own antioxidants, making them incredibly stable.

What I find fascinating is how the ripening process affects their nutrient availability—a perfectly ripe avocado tastes better and provides more bioavailable nutrients.

I’ve learned to store them with apples to speed up ripening when needed, as the ethylene gas helps develop their creamy texture.

18. Dark Chocolate 70%+ (12g fat/oz) 

The fascinating thing about dark chocolate’s fat content is that it contains stearic acid, a unique type of saturated fat that doesn’t impact cholesterol levels like other saturated fats.

Through my chocolate tastings, I’ve discovered that the fat content contributes to flavor release and the smooth mouthfeel.

Higher cocoa percentages typically mean more beneficial compounds but also require a more refined palate to appreciate their complex flavors.

19. Tahini (16g fat/2 tbsp) 

Made from ground sesame seeds, tahini offers a unique fatty acid profile that supports calcium absorption, which is particularly important since sesame seeds are also rich in calcium.

Its creamy texture comes from a high concentration of healthy fats, making it an excellent base for dressings and sauces.

I’ve found that different tahini brands can vary significantly in bitterness – the lighter varieties tend to be milder and more versatile in recipes.

20. Olives (11g fat/3.5 oz) 

The process of converting fresh olive into edible fruit is an interesting one that truly heightens their accessibility to healthy fats.

Different types yield slightly varying fat levels – for instance, Kalamata olives will typically contain greater levels of healthy fats than green ones.

The best part of olives for me is the fact that they can make flavors in dishes stand out while providing you with healthy fats in their purest form.

The brine they are preserved in can also contribute mineral content, making them a healthy whole-food source of fat.
