The Best Fats for Babies: What Breast Milk Teaches Us About Choosing Oils

Ever noticed how breast milk keeps babies satisfied for hours?
There’s a powerful reason behind it — fat.

Fat is not just a “filler” in your baby’s food. It’s one of the most essential nutrients for their growth, especially during the earliest stages of life. From brain development to energy production, fat plays a starring role in your baby’s nutrition story.


What Does Fat Actually Do for Babies?

You know how rapidly babies grow in their first year? That’s not just bones and muscles — it’s brain and nervous system development, too.

Fat is the fuel for all of it.

Here’s why fat is absolutely vital for babies:

  • Brain growth: The brain is nearly 60% fat, and it triples in size in the first few years of life.
  • Energy: Babies need fat to support their sky-high energy needs.
  • Cell structure & hormones: Every single cell in your baby’s body is wrapped in a fat-based membrane.
  • Nutrient absorption: Vitamins A, D, E, and K — critical for growth — can only be absorbed with fat.

In short? No fat, no development.


What’s in Breast Milk: The Natural Fat Blueprint

Calorie breakdown: 50% fat, 40% carbs, 10% protein

Breast milk is naturally designed to nourish your baby perfectly. It delivers about 50% of its calories from fat, about 40% from carbohydrates, and the rest from protein — a balance that ensures babies stay energized, satisfied, and supported in their development.

The three types of fat in breast milk

Breast milk contains a beautiful mix of fats:

  • Saturated fats (~40%)
  • Monounsaturated fats (~45%)
  • Polyunsaturated fats (~15%)

Each type plays a specific role in building your baby’s brain, cells, and immune system.

Saturated Fats: The Surprising Supporter of Baby Wellness

Saturated fat makes up a significant portion of the fat in breast milk. It provides a stable source of energy, which is especially important for rapidly growing infants. 

One key component of saturated fat in breast milk is lauric acid, which has natural antimicrobial properties — supporting your baby’s developing immune system. 

Saturated fats are also critical for building strong cell membranes and aiding in nutrient absorption.


But Wait — Aren’t Saturated Fats Supposed to Be Unhealthy?

It’s a common concern among parents — and an understandable one. Saturated fat often gets a bad reputation in adult nutrition, but the truth is: it plays a vital role in a baby’s diet. 

In fact, nearly half of the fat in breast milk is saturated. Babies are biologically designed to thrive on it.

What truly matters isn’t whether a fat is “saturated” or “unsaturated” — it’s about the quality and source. Natural, stable fats from whole foods like coconut oil, whole milk, or animal fats very different from the saturated fats found in highly processed foods like French fries or fast food.

At Little Judah, we focus on clean, real-food fats that your baby’s body can recognize, absorb, and use — just like nature intended.

Monounsaturated Fats: Heart-Healthy and Baby-Friendly

This is the largest type of fat in breast milk. Monounsaturated fats are known for their role in supporting healthy brain and nerve development. They also contribute to cardiovascular health and help regulate cholesterol levels. 

A common source of monounsaturated fats in baby food is extra virgin olive oil, which aligns closely with the fat composition of breast milk.

Polyunsaturated Fats: Tiny Amounts, Big Impact

Although polyunsaturated fats are present in smaller amounts, they are incredibly important. This group includes essential fatty acids like omega-3 (DHA, EPA, ALA) and omega-6 (LA), which the body cannot produce on its own. 

They are vital for cell function, hormone production, and especially brain and eye development in babies. 

However, maintaining the right balance between omega-3 and omega-6 is crucial, as an excess of omega-6 — often found in seed oils — may contribute to inflammation.


The Oils We Choose: Mimicking the Breast Milk Balance

Why we use virgin coconut oil and extra virgin olive oil

At Little Judah, we focus on whole, minimally processed oils that reflect the natural fat ratios in breast milk:

  • Virgin coconut oil and coconut milk for its saturated fat and lauric acid content
  • Extra virgin olive oil for its rich monounsaturated fat profile

These healthy fats help your baby digest food well, stay full, and grow strong — just like nature intended.

How our fat sources support growth and digestion

Both coconut and olive oils are gentle on baby tummies, shelf-stable without chemical processing, and work beautifully together to deliver balanced nourishment.

Why Seed Oils Don’t Belong in Baby Food

Common seed oils and their processing concerns

Many baby foods — and even well-meaning parents — use seed oils like canola, soybean, corn, rice bran, or grapeseed oil because they’re affordable or commonly believed to be healthy. However, most of these oils undergo heavy refining, involving high heat and chemical processing to extract and stabilize them.

The oxidation issue: What happens when these oils are heated

Even “cold-pressed” versions of seed oils are rich in omega-6s, which oxidize easily when exposed to heat — the kind of heat used in baby food production. Oxidized oils can create harmful compounds your baby doesn’t need.

Inflammation and imbalance: The risks of excessive omega-6

Modern diets are already flooded with omega-6 fats. Adding more through baby food can increase the risk of chronic inflammation over time — something we’re determined to avoid.


Choosing Clean Fats with Confidence

When it comes to feeding your baby, the type of fat used matters just as much as the ingredients themselves. Here's a simple guide to help you choose wisely:

Best Fats for your baby:

  • Virgin or extra virgin coconut oil
  • Extra virgin olive oil
  • Fresh coconut milk
  • Natural animal fats (e.g., from pasture-raised meats)
  • Butter and ghee
  • Full-fat / full-cream milk
  • Full-fat plain yoghurt and cheese
  • Avocados
  • Whole eggs (with yolks!)
  • Fatty fish like wild salmon
  • Fattier cuts of meats (like chicken thigh or short ribs)

Fats to Avoid:

  • Canola oil
  • Grapeseed oil
  • Soybean oil
  • Corn oil
  • Rice bran oil
  • Vegetable oil blends (usually a mix of refined seed oils)

Smart Questions to Ask When Buying Ready-to-Eat Baby Meals:
– Does this product contain any added fats or oils?
– What type of fats are used?
– Are the oils cold-pressed and minimally processed, or refined and industrial?
– Do the fats used reflect the natural fat profile found in breast milk?

By asking these questions and reading labels carefully, you can make informed choices that align with your baby’s nutritional needs — and feel confident about what’s going into every bite.
