Animal Fats vs Plant Fats: What Science Says About Inflammation

Inflammation is at the root of many chronic diseases, from arthritis to heart disease. But did you know the fats you eat can either fuel or fight inflammation? Recent research reveals key differences between animal fats and plant fats and understanding them can help you make healthier choices every day.

We’ll break down the science, debunk common myths, and share simple, healthy swaps to support your overall wellbeing.

The Science of Fats and Inflammation

Not all fats are created equal. While they’re essential for energy, hormone production, and nutrient absorption, the type of fat you consume matters, especially when it comes to inflammation.

Animal Fats

Animal fats, such as those found in red meat, butter, cheese, and processed meats, are typically high in saturated fats. Some studies suggest that high intakes of saturated fats can:

• Increase production of pro-inflammatory molecules in the body

• Elevate LDL cholesterol, which is linked to cardiovascular inflammation

• Alter the gut microbiome, contributing to systemic inflammation

However, it’s worth noting that not all animal fats are equal. For example:

• Fatty fish (e.g. salmon, sardines, mackerel) are rich in omega-3 fatty acids, which are anti-inflammatory.

• Grass-fed meats tend to have slightly better omega-3 to omega-6 ratios compared to grain-fed meats.

Plant Fats

Plant-based fats, found in foods like olive oil, nuts, seeds, and avocados, are typically high in unsaturated fats, particularly monounsaturated and polyunsaturated fats. These are known to:

• Reduce levels of C-reactive protein (CRP), a marker of inflammation

• Support heart and brain health

• Improve the balance of omega-3 and omega-6 fatty acids when consumed thoughtfully

For example:

• Extra virgin olive oil — a staple of the Mediterranean diet — is rich in anti-inflammatory compounds like polyphenols.

• Walnuts, chia seeds, and flaxseeds are excellent plant-based sources of omega-3s, which help counteract inflammation.

Healthy Swaps to Lower Inflammation

Small, sustainable changes can make a big difference. Here are some simple swaps backed by research:

Instead of…	Try…	Why
Butter or lard	Extra virgin olive oil	Rich in anti-inflammatory polyphenols and monounsaturated fats
Processed meats	Grilled salmon or mackerel	Provides omega-3 fatty acids to combat inflammation
Cream-based sauces	Avocado or tahini-based dressings	Packed with healthy unsaturated fats
Crisps and fried snacks	A handful of mixed nuts	Offer anti-inflammatory compounds and keep you fuller for longer
Standard cooking oil	Cold-pressed rapeseed oil	High in omega-3s and stable at high temperatures

Balance is Key

It’s important to remember that you don’t need to avoid animal fats completely. Moderation and balance are crucial:

• Enjoy lean meats and fatty fish a few times a week.

• Limit highly processed meats and deep-fried foods.

• Prioritise plant-based fats daily.

A Mediterranean style eating pattern; rich in vegetables, whole grains, legumes, nuts, olive oil, and fish, has been consistently linked with lower levels of chronic inflammation and better long-term health outcomes.

Takeaway

When it comes to inflammation, the type of fat matters more than the total amount. Generally, plant-based fats and omega-3-rich animal fats are your allies, while excessive saturated and trans fats can tip the balance towards inflammation.

Making simple, science-backed swaps can help protect your heart, joints, and overall health without feeling restrictive or complicated.

Pro tip: Next time you cook, try swapping butter for extra virgin olive oil and sprinkle some flaxseeds on your salad. Small tweaks today can build an anti-inflammatory foundation for the future.
